Joe F. Hale, FRCI President ’Tis the Season to Be Busy If RCI thrives on activity – and the track record indicates it does – then November was a jolly month for our association. Within an eight-day pe¬ riod, we presented our levels I and III courses in several cities, administered RRC and RRO exams (to over 40 peo¬ ple), and held three regional meetings. I personally had the pleasure of attend¬ ing all three of these meetings. RCI Says Aloha to Hawaii Our first regional meeting in Hawaii was a great success and revealed a high level of enthusiasm among our island colleagues. The meeting also demon¬ strated that RCI is expanding its reach toward an increasingly greater variety of professionals. The audience repre¬ sented a good cross-section of the in¬ dustry – contractors, materials suppliers, architects, engineers, insur¬ ance representatives, and state govern¬ ment officials. More than 20 people attended the Basics of Roofing, proving once again that this course is a valuable educa¬ tional tool. It additionally provides more visibility to our mission’ and cre¬ ates growth for the Institute. Think what we could accomplish if each re¬ gion hosted the Basics of Roofing In This Issue President’s Message . . 1 Roles of Professional Roof Consultants and Professional Roof Contractors . 5 Proper Eaves Details for Asphalt Shingles . 8 State Farm Boosts RCI ’ s Di saster Research Effort . 10 Retirement Programs: A Guide for Business Owners and the Self-employed . 11 Book Review . :. 12 Institute Announcements . 13 News From Our Regions . 16 RICOWI Updates . 19 We Get Letters . 21 From Our Members . 21 Convention Update . 23 When Are Innocent Contractors Subject to Environmental Liabiltiy as “Owners” and Operators” ? . 25 Industry News . 26 Calendar of Events . 27 Roof Consultants Institute twice a year! Further, in response to requests from the private sector, we’ll gladly bring the course to individual companies that want to present it. This course is very beneficial to all ele¬ ments of the industry. Any member can sponsor the Basics of Roofing at his/her firm with an attendance of 20 or more people. Texas Tech Wind Research After leaving the land of beautiful beaches, we headed toward the big countiy – Lubbock, Texas. Dr. Jim McDonald, Director of the Institute for Disaster Research at Texas Tech Uni¬ versity (TTU), explained to a well in¬ formed crowd TTU’s edge wind research which RCI helps to fund. Af¬ terward he gave us a tour of the Wind Engineering Research Field Labora¬ tory, an impressive facility that moni¬ tors and measures wind speed, direction, temperature, barometric pressure, and relative humidity. RCI can be proud of its efforts in Region Four, where membership has increased to 65, up significantly from 39 just one year ago. These people take seriously our Add-A-Member contest! I personally took advantage of this mo¬ mentum to encourage more growth, to take a few pictures for our RCI mem¬ bership cards (coming soon), and to urge the group to be “good evangel¬ ists” and spread the word. National Institute of Stand¬ ards and Technology We rounded out the week in Gaith¬ ersburg, Maryland, with a tour of the National Institute of Standards and Technology (NIST). As usual for Re¬ gion One, attendance was high. Dr. Walt Rossiter, of NIST’s Center for Building Technology, is a leading ex¬ pert on building and insulation materi¬ als. His contributions have benefitted the whole field of building technology as well as the roofing industry. Doug Burch, of NIST’s Building and Fire Research Laboratory, discussed his new interactive software “MOIST” which models a wall assembly for the purpose of detecting the migration of moisture. “Think what we could ac¬ complish if each region hosted the Basics of Roofing twice a year! … We’ll gladly bring the course to in¬ dividual companies that want to present it. ” Ray Corbin, Director of BURSI, also made excellent presentations at this meeting. Ray’s value to the indus¬ try is matched only by his value and commitment to RCI. Ray is a long time member of the Institute, since 1987, and RCI has been enriched by virtue of his time, effort, and expertise. Our Registered Roof Observer (RRO) program received an important boost this weekend when seven people pulled themselves away from the seminars to take this exam. We hope to see many more RRO exams given at the regional level. We owe much gratitude to Jim Magowan, RRC, whose untiring dedication has made this program a reality. Jim is both a past president and a fellow; his record is well known. However, not everyone realizes that Jim still continues his hard work and service to the Institute, as evidenced by the success of the RRO program. One more important event came to pass: I met with Larry Gallo and Walt Rossiter and set up a return meeting during which we would develop closer involvement between NIST and RCI. Our goal is to go beyond liaison and work together to implement important research programs. This is an exciting opportunity for RCI and we’ll keep you informed of all developments. What’s Ahead? With 1993 winding down, RCI looks forward to an exciting new year. Two very important events are already in the planning stages. 1) We have been invited by the Oak Ridge National Laboratory to help or¬ ganize a reroofing workshop to be held in May of 1994. RCI will provide speakers on three topics: the reroof/recover decision, practical considera¬ tions in roof design, and field evaluation of roofing. 2) Next February, RCI will sponsor its first Mid-Atlantic Building Enve¬ lope Conference, which will bring to¬ gether designers, consultants, and facilities managers to discuss prob¬ lems and explore new technologies and practices affecting the building en¬ velope. Look for more information about these coming events and the recent region meetings inside this issue. ■ 2 Interface Nov/Dec 1993 Roof Consultants Institute RCI Announces Its Inaugural Mid-Atlantic Building Envelope Conference CONSULTANTS!

Mr. Magowan has been involved in the roofing industry for over 40 years and is currently president of Roof Indus¬ try Consult¬ ants, Inc., a roofing and moisture proofing firm located in Dublin, California. Mr. Magowan has been published in CSI’s The Construction Specifier and various other industry publications. He has participated in seminars and panels, and acted as moderator for Western States Roofing Contractors Association, National Roofing Contractors Association, Western Construction Consultants, and RCI’s level one education course. Jim is presently Chairman of the Qual¬ ity Assurance Observer Committee. Purpose The purpose of this document is to identify the duties, responsibilities, and expectations of the professional roof consultant and the professional roofing contractor when each is en¬ gaged in a common project. General The construction industry is unique in the sense that the projects it provides are each a first-time, full-scale proto¬ type. There is seldom an opportunity to test the prototype, and it must func¬ tion in the intended manner when it is complete. Although the materials and much of the equip¬ ment incorporated in a roof can be tested and their per¬ formance in other situations is known, many otherfactors vary with each pro¬ ject. Therefore, the unique combina¬ tion inherent in each constructed project is a new application, succeed¬ ing or failing on the ability, skill, and knowledge of the design and construc¬ tion team. The owner and consultant cooperate to select a contractor for the project team. The “team” consists of the owner, the professional roof consult¬ ant and the professional roofing con¬ tractor. When the members of the project team are competent and work together, chances for quality and prof¬ itability for all are greatly increased. It must be noted that the responsi¬ bilities and actions of the consultant and the contractor may be impacted by local jurisdictions. These laws, stat¬ utes and regulations vary by jurisdic¬ tion. The consultant and contractor must be aware of and follow these requirements. Roof Consultant While the roof consultant’s respon¬ sibilities vary depending on the con¬ tractual arrangement, his or her responsibility is defined and described in the consultant’s contract with the owner for professional services. Up to the start of construction, the consultant has primary control over the project’s quality by developing construction documents. When construction be¬ gins, quality control becomes the con¬ tractor’s role and quality assurance be¬ comes the consult¬ ant’s. The consultant’s role shifts from specifying project quality to ob¬ serving the construc¬ tion process to determine if the project follows the design intent and quality standards. The various quality efforts require careful coordination. Roof consultants must provide de¬ tailed quality control criteria and pro¬ cedures to be carried out during construction, as stipulated in the de¬ sign documents. These include testing and quality assurance observation us¬ ing the specified test procedures, and distribution of test results. Test results must be promptly reviewed by the con¬ sultant. Testing specifications must clearly state what constitutes failure of each test. Should the failure of any test or series of tests be considered to have an adverse effect on overall quality, detailed communications procedures must be established. These should in¬ volve stating who must be notified, When construction begins, quality control becomes the con¬ tractor’s role and quality assur¬ ance becomes the consultant’s. Nov/Dec 1993 Interface 5 Roof Consultants Institute both orally and in writing, and who is authorized to make such decisions. The roof consultant’s position on the construction team is defined and described in the contract documents and in the consultant’s agreement to provide professional services. Most agreements for professional services are customized to accommodate a spe¬ cific construction project. Recogniz¬ ing the controlling force behind the project documents and his contract with the owner, the roof consultant is generally expected to: • Consult with and advise the owner, acting as the owner’s repre¬ sentative, as stipulated in the con¬ tract between the owner and the roof consultant. • Convene and attend conferences and meetings with the roofing con¬ tractor and others. Prepare and cir¬ culate minutes. • Maintain orderly files of all job records. Keep a diary or log book of weather conditions with names, addresses, and telephone numbers of the contractor, subcontractors, and major suppliers. • Provide resident quality assurance services with a continuing pres¬ ence at the site during administra¬ tion of the construction contract. • Have authority to act on behalf of the owner to the extent provided in the contract between the owner and the roof consultant. • Have no authority orresponsibility for the contractor’s means, meth¬ ods, techniques, or procedures of construction. • Have no authority or responsibility for the roofing contractor’s safety precautions and programs, or for failure of the contractor to comply with laws, rules, regulations, ordi¬ nances, codes or orders applicable to the roofing contractor’s work, except to bring deviations to the contractor’s and owner’s attention. • Di sapprove of the roofing contractor’s work while it is in progress if the roof consultant believes that such work does not conform to project requirements or will preju¬ dice the integrity of the design con¬ cept. Once identified, these discrepancies must be brought to the attention of the contractor. In the event this cannot be resolved at this level, it must be brought to the attention of the owner for resolu¬ tion. • With reasonable promptness, pro¬ vide necessary interpretations and clarifications of the contract docu¬ ments; issue work directive changes; and prepare change or¬ ders as required. • With reasonable promptness, re¬ view and take appropriate action in respect to shop drawings, samples, and other data the contractor is re¬ quired to submit. (The contractor who fails to submit and have ap¬ proved a shop drawing submittal schedule cannot expect prompt¬ ness when many shop drawings are submitted to the consultant all at once.) It is the consultant’s respon¬ sibility to review such shop draw¬ ings with equal care and attention. • With reasonable promptness, evaluate alternatives and substitu¬ tions proposed by the roofing con¬ tractor. • Submit to the contractor, before substantial completion, a list of items that remain to be completed or corrected, and conduct a final inspection with the owner and roofing contractor. Verify that all items on the final list have been completed or corrected. • Determine if warranties and main¬ tenance manuals and other re¬ quired data have been assembled by the contractor and forwarded to the owner. • Prepare as-built plans and specifi¬ cations, as required. • Accompany the owner’s personnel and inspectors during site visits, as well as representatives of agencies having jurisdictional interest. • Carefully review applications for payment submitted by the contrac¬ tor and make prompt recommen¬ dations to the owner. • Conduct quality assurance obser¬ vations, issue a statement of sub¬ stantial completion, and recommend final payment to the roofing contractor, according to the contract documents. • Be the initial interpreter of the re¬ quirements of the contract docu¬ ments. • Review claims, disputes, and other matters concerning the accept¬ ability of the work and change in contract price or time. The above guidelines outline the roof consultant’s conduct in construc¬ tion administration and specifically state the consultant’s position on the team. For any team to function suc¬ cessfully, all team members must fo¬ cus on the project’s goals. If the consultant observes the contractor us¬ ing a method that will not produce an acceptable result, the consultant should inform the contractor’s super¬ intendent and log the event. One should never wait until faulty work is complete before reporting it. Delays in passing information, processing pay¬ ment applications or similar actions can be instrumental in lowering the quality of any project. The above guidelines apply to al¬ most all situations except those that are catastrophic or subject to imminent disaster. The consultant should report any unsafe methods that he observes, but he must never recommend or su¬ pervise corrective measures. Any member of the team who becomes aware of unsatisfactory methods is ex- 6 Interface Nov/Dec 1993 Roof Consultants Institute pected to promptly respond to avoid or minimize serious consequences. If the roof consultant has contracted directly with the owner for design, the consultant is legally and ethically re¬ sponsible for the project’s design qual¬ ity. Roofing Contractor Roofing contractors lead the quality control effort as the actual constructors while the roof consultant leads the quality assurance effort. The contrac¬ tor’s primary responsibility is to meet the quality standards outlined in the project manual and contract between roof contractor and his client. Quality can be seriously eroded if the contrac¬ tor does not carefully review the con¬ tract documents at the start and evaluate specific and unforeseen risks. The following is a list of responsi¬ bilities and limitations of authority that apply to roofing contractors on most jobs. The items are not listed in order of importance. It should be clear that the project delivery plan of a given project is binding. The roofing con¬ tractor should: • Provide supervision and control the execution of the work. The con¬ tractor is also responsible for means, methods and sequences of construction, and project safety. • Provide timely progress schedules, shop drawings, submittal sched¬ ules, signs, utilities, and office fa¬ cilities as required. Delayed execution in these areas negatively influences team performance. Make a thorough review of shop¬ drawing submittals and keep sup¬ pliers on schedule. Be receptive to different opinions and attempt to quickly resolve any differences. Failure to do so can result in serious disputes. Maintain record documents at the site with properly noted changes made during construction. Be an active member of the team. The roofing contractor may sug¬ gest an alternative material or pro¬ cedure which may reduce costs and meet quality specifications. Pro¬ posed changes, however, must be communicated in writing to the roof consultant through proper channels to determine if the pro¬ posal adheres to the overall design concept. An “add” or “deduct” number must be included. Respond constructively to quality control and assurance issues gener¬ ated by sub-contractors, suppliers, and the roof consultant. The roof consultant and his or her assistants are responsible for identifying po¬ tential problems or quality control/ assurance issues. The roofing contractor is solely responsible for installing or fabricating materials, equipment, and accessories that meet the specifications. If an unexpected event occurs, co¬ operate with other members of the construction team to provide an ap¬ propriate resolution. Be familiar with the contract docu¬ ments and follow the project deliv¬ ery plan. A competent contractor knows the contract documents. • Provide material and system sam¬ ples at the direction of the consult¬ ant when specified or required by the contractor or owner to demon¬ strate that proposed materials and equipment are acceptable. • Recognize and respect the author¬ ity of the roof consultant as specifi¬ cally noted in the contract documents and his contract with client. • Cooperate fully with and provide the owner, roof consultant, and in¬ spection authorities access to the project for adequate inspection. When potentially hazardous condi¬ tions occur during construction, the roofing contractor or subcontractor executing the hazardous activity is di¬ rectly responsible for detailed plan¬ ning and scheduling to minimize risks to the public and site personnel. Plans must be communicated to all con¬ cerned parties, including other con¬ tractors on the site, the roof consultant, and inspection officials. Summary The relationships of a project often become adversarial between the par¬ ticipants rather than a team effort to meet mutual objectives. Failure to meet the responsibilities as defined above is usually the underlying reason. RCI’s interest is to nurture greater un¬ derstanding and mutual efforts toward better-working relationships; thus, we stand available and welcome the op¬ portunity to participate in all efforts with this as our objective. ■ QUOTE OF THE MONTH “An expert is an individual who has made every conceivable mistake in a narrow field. ” Dr. Edward Teller Nov/Dec 1993 Interface 7 Roof Consultants Institute Proper Eaves Details for Asphalt Shingles R.L. Corbin Ray Corbin is Director for the Better Understanding of Roofing Systems In¬ stitute (BURSI), a 21-year old national educational program on roofing sys¬ tems de¬ signedfor ar¬ chitects, en¬ gineers and building owners, which is sponsored by Schuller In¬ ternational, Inc., Manville® Roofing Systems. Mr. Corbin is also a faculty member ofRIEI, has served as Chair¬ man of the Code Committeefor ARMA, and is a member of BOCA, SBCCI, ICBO, ASIM, CSI andRCI. He holds four U.S. Patents for roofing shingle design and application and has pub¬ lished numerous technical articles. It’s obvious that a well constructed building begins with a good founda¬ tion. What may be less obvious is that a well constructed asphalt shingle roof begins with proper application at the eaves. Without it, the finished roof will be far less than satisfactory. It’s impor¬ tant, therefore, to pay close attention to the eaves details once the APA rated decking has been installed. Here are some recommendations that should prove helpful. First, install a drip edge along the lower leading edge of the deck. Drip edges come in the basic “L” angle or the “T” shape. Either type will afford the needed protection to the leading edge from running and/or dripping water. The “T” shape also gives a point to trim the shingles as it provides the necessary 1/2-inch overhang required to direct the water flow into the water carrying system. Second, add an eaves flashing strip, preferably with one of the modified bitumen, ice-and-water protection membranes. This type of additional protection is especially important where cold weather conditions exist (January temperatures of 25 degrees Fahrenheit or colder) or in warm, rainy climates where pine needles and other debris accumulate along the eaves, creating a damming action similar to that of ice and snow. In order to guard against the resul¬ tant leaks from the damming effect, install a single ply of an ice-and-water (or pine needle) protection membrane directly over the decking and drip edge. Position the membrane to a point at least 12 inches inside the interior wall line on slopes of 4″ in 12″ (or greater) and to at least 24 inches inside on the slopes from 2″ in 12″ up to 4″ in 12″. Overlap the underlayment on top of the membrane about 4 inches (19 inches for low slope conditions). The tacky nature of the membrane will seal the penetrating shanks of the nails and also act as a barrier to backed-up water. The third and final consideration re¬ garding eaves is the starter course. 8 Interface Nov/Dec 1993 Roof Consultants Institute Correctly applied, it provides a straight edge starting point for the shingle roof. It also forms an important part of the roof’s water-shedding system. When using an “L” shape drip edge, make certain that the starter course extends 1/2-inch beyond the drip edge. The starter course is cut even when the “T” shape drip edge is installed. A chalk line should be used to get the starter course running straight along the eaves. There are three starter course meth¬ ods: 1) a 9-inch wide roll starter strip; 2) inverting a full shingle; and 3) cut¬ ting a starter from a three-tab shingle. The roll method is quickest, and when applied straight, offers a good clean line to follow. The applicator must apply tab cement along the un¬ derside of the first full course of shin¬ gles to seal them against wind blow-off. When using shingles that come with a seal stripe along the un¬ derside (as do most laminates), the tab cement is not needed. The second method, inverting a full shingle, is favored by many applica¬ tors. One advantage is that it offers a factory cut edge to use as a guide when applying the first course. However, the inverted shingle method also has a po¬ tential problem. Unless tab cement is properly used (as with the roll method), the first course of shingles is unstuck and prone to start a blow-off action on the roof. There is also the added problem of creating a water trough 12 inches up from, and running parallel to, the eaves. This situation is created by using a 12-inch first course shingle over a 12-inch starter shingle. In lower sloped roofs, the usual result is the lateral movement of water along the trough and a penetra¬ tion of the water shedding system at the butted shingle end joints. The third method of trimming the tabs of three tab shingles is recom¬ mended by most shingle manufactur¬ ers and offers the most positive approach of the three. This method requires a little more labor to trim the tabs off just below the seal stripe. However, since it doesn’t require the use of tab cement, it’s actually the quickest method of all. The applicator simply trims (cuts) the tabs off of the three tab shingle. Trim four inches (minimum) off the first starter piece in order to prevent an end joint in the first course from falling over a starter course end joint. The cut starter shingle is then applied with the sealing stripe closest to the eaves edge, nailing three inches up and not within two inches of where a cutout in the starter course will fall. This nailing procedure should be carried out in all three methods. As with all aspects of application, a few positive steps during the setup stage will result in a better-applied roof. By designing the roof to resist blow-offs along the eaves, you will, ultimately, help to prevent a blow-off action that could peel off the rest of the roof. It’s also a good idea to use the chalk line to snap on occasional verti¬ cal lines in order to apply the entire roof with proper vertical alignment. The result will be a roof that looks good — and shingles that stay on and keep the water out. ■ LIVE ROOFING DEMO!

Nov/Dec 1993 Interface 9 Roof Consultants Institute STATE FARM BOOSTS RCI’S DISASTER RESEARCH EFFORT Critical pre-disaster data will make an important difference in analyzing destruction caused by high wind speeds. In the October, 1992, special edition of Interface, Sam Huff, RRC, de¬ scribed the tremendous recovery effort that took place in the aftermath of Hur¬ ricane Andrew. His words painted a poignant scene of families and busi¬ ness people alike, trying to salvage what they could — without the help of electricity, water, hot food, and sani¬ tary facilities. “We saw numerous examples of car¬ ing and sharing. Neighbors were help¬ ingneighbors; city, county and private business employees whose own homes had been destroyed were hard at work under terrible conditions, helping to provide the goods and services neces¬ sary to survive and to begin the re¬ building process. ” Heroic acts of everyday people such as these brought hope and determina¬ tion to an otherwise tragic situation. Equally important, though, are the continuing research efforts that may prevent such devastation from occur¬ ring again. RCI’s Disaster Research Program, begun in 1990, has developed a track record for gathering post-disaster data on damaged buildings. Renown re¬ searchers presented their findings at our last convention in Orlando, Flo. However, research to date has been frustrated by the lack of pre-disaster information. To effectively evaluate the performance of various roof sys¬ tems, designs, and construction prac¬ tices, the research program requires both pre- and post-disaster stand¬ ardized data on specific roofs. Recognizing the need for this type of information, State Farm Insurance Co. has agreed to supply RCI with accurate data on over 40 of their claims offices located within 60 miles of the east coast, from Florida up along the coastal storm belt. This cooperative effort was made possible by Sam Huff, RCI’s director of the Disaster Re¬ sponse Program, who negotiated the arrangement with Ken Sampen, State Farm’s Assistant Vice President of Administrative Services, and Lon Bradle. Assistant Director of Building De¬ sign and Construction. According to the agreement. State Farm will provide RCI with the following information about each building: • date of construction • deck type • type and thickness of roof insu¬ lation • type of roofing membrane • method of securement for the various components • photo of rooftop The standards for specifications, construction, and maintenance are consistent for all buildings owned by State Farm, providing a built-in con¬ trol factor for our research. This pre¬ sents a unique opportunity by eliminating many variables. “These buildings are all built to the same, high standards,” explains Sam. “If we know in advance the kind of construction we’re dealing with, after a hurricane hits we can determine how well these roofs withstood the high wind speeds.” Once the construction information has been received from State Farm, weather stations will be installed on selected roofs to measure wind speed, both sustained and gusts. We can cor¬ relate this information with what is observed on the roofs and analyze the results. RCI will additionally share the data with any agency requesting it. “Our hope is that this research will reveal which roofs withstand the dam¬ aging winds and which processes are most effective in preventing damage,” said Ken Sampen. “The information obtained will be disseminated throughout the construction industry, and will come back full circle in the form of better construction and re¬ duced losses. This is a win-win situ¬ ation for everyone: building owner, contractor, and insurer.” This type of proactive effort is what we need in the construction industry to improve design specifications and construction practices, thus producing better and safer buildings overall. ■ WHA T IS A WEA THER STA TION? To help obtain accurate wind data, weather stations will be mounted on selected roofs where and when there is threat of a hurricane or severe storm. Each weather station consists of a light-weight, yet sturdy, anemometer equipped with wind cups and a vane, used respectively for sensing speed and direction. A small thermometer will be mounted separately. The whole assembly weighs less than three pounds. Data travels to an AC-powered monitor display mounted with the ane¬ mometer. This monitor stores the information, along with the time and date, for up to 24 hours. An accompanying software program helps to manage, store, graph and analyze the data. 10 Interface Nov/Dec 1993 Roof Consultants Institute Retirement Programs: A Guide for Business Owners and the Self-employed Jim Hunt John Edwards Banta Jim Hunt was in sales with Owens- Corning for 11 years prior to mak¬ ing a career change into finan¬ cial planning with Kidder, Peabody & Co. Over the years, he was actively involved with consultants, architects, contractors, and distributors in the commercial roofing industry. Addi¬ tionally, he was an associate member of the Chicago, Midwest, and National Roofing Contractors Associations. After completing his Master ’s degree in finance and marketing at the J.L. Kellogg Graduate School of Manage¬ ment at Northwestern University, he made a career shift to personal and business financial management. John Edwards Banta is Jim ’s partner at Kidder ‘s Chicago office. John is completing his Master ’s de¬ gree in finance at the Graduate School of Business at the University of Chicago, has over ten years experi¬ ence in financial planning, and is a company Vice President. He has com¬ pleted the Portfolio Management Pro¬ gram at the Investment Institute and is a licensed Advisory Agent. In addition to performing a management role in the securities industry, John has con¬ sulted or acted as a principle in sev¬ eral business ventures. Qualified Plans Qualified plans have several avail¬ able formats, and are typically distin¬ guished by their contribution features. The most commonly used plans in¬ clude: Money Purchase Plan – allows you to contribute up to 25% of annual compensation, to a maximum of $30,000 per plan participant. Contri¬ bution levels selected are inflexible and must be contributed regardless of the firm’s profitability. Profit-Sharing Plan – allows you to contribute up to 15% of annual com¬ pensation, to a maximum of $30,000 per plan participant. Your contribution percentage can be flexible from year to year as long as it is not discriminatory. Cash or Deferred Arran gement £401kl – a modification of a profit sharing plan. It allows your employees to contribute to the plan themselves, and/or to make certain elections con¬ cerning your contributions on their behalf. The maximum that any participant may elect to defer into the plan is 15% or $8,994, whichever is less. However, employer matching may bring the total contribution up to $30,000. Certain discrimination tests apply to this type of plan. Defined Benefit Plan – features ac¬ tuarially computed contribution which in some cases may be higher than com¬ pensation. This plan is used to maxi¬ mize contributions, while ensuring a specific income at retirement. Annual contributions are not as flexible as the profit-sharing plan, and due to the ac¬ tuarial computation involved, may be more expensive to maintain. The SEP Alternative As an alternative to the qualified retirement plan, you may wish to con¬ sider the easy maintenance and econ¬ omy of the Simplified Employee Pension plan. The SEP is structured so that you make contributions into IRAs established by each eligible employee. Your employees can also make annual IRA contributions directly into their SEP accounts, however the deductibil¬ ity of these contributions is subject to restrictions. All participants direct their own investments, reducing con¬ siderably your fiduciary liability. As with a profit-sharing plan, the SEP contributions are a flexible 15% of salary, to a maximum of $30,000 per participant, whichever is less. The SEP generally costs much less than other business retirement plans and requires no complicated govern¬ ment filings. However, its eligibility requirements are stricter and it has no provisions for deferred vesting, par¬ ticipant borrowing, or favorable treat¬ ment of lump-sum distributions. Obviously, each plan has different features and applications which should be weighed against your company’s needs before you make a final selec¬ tion. Of course, you should always consult a tax or pension professional before making your final selection. Next Issue: Which plan makes sense for you?

Phalen Jr. Professor Emeritus of Mechanical Engineering Technology Northeastern University, Boston, Mass. PTR Prentice Hall. 734 pages. $96.00 By Lyle Hogan, PE, RRC This text begins by analyzing the origin of single ply roof membranes. Section 1-10 contains a blunt discus¬ sion of liability of design — a feature commonly disregarded by some who select and specify roof systems. Lo¬ cated later in Chapter One is the best justification for factors of safety I have encountered. Chapter Two explores recognized engineering properties of polymeric membranes. The topics discussed in¬ clude surface hardness, load-strain relationships, permeability, flame re¬ sistance, and many others. Later, meteorological study is ex¬ amined as it relates to the statistical (and therefore financial) justification of making a perfect product. The same logic (financial) provides rea¬ soning for an industry’s failure to do the same. Professor Phalen’s book places strong emphasis on the topic of wind. Fully nine of twelve chapters visit the issue in some respect. Chapter Six contains a thorough discussion of parapet wall height and the corre¬ sponding influence of wind uplift. Chapter Seven contains excellent il¬ lustrative documentation of stone ballasting rates and particle size ver¬ sus coverage. This portion of the text offers some surprising revelations that seem to contradict conventional thinking on this subject. Many roofing technologists are aware of wind protection afforded by tall structures adjacent to another roof under study; however, little un¬ derstood is a “channeling” behavior, effectively increasing the prevailing wind’s influence. This concept is ex¬ plored in Chapter Eight. Chapter Nine summarizes the steps leading to development of an interlocking, paver block, ballasting system. Most of that work is predi¬ cated upon strong technical refer¬ ences such as wind tunnel work by Kind and Wardlaw (household names in this type of science). There is especially helpful treatise on fas¬ tening contained in Chapter Eleven. Thread geometry, eccentric loads, and issues of corrosion are analyzed. Chapter Twelve rounds out the work by dealing with thermal considera¬ tions and comparative properties of popular insulations. Seemingly omitted, however, is the reference to air barriers (although Article 6-9 describes requisites for this issue). I would not register this observation but for the fact that, as stated earlier, nine of twelve chapters explore wind uplift issues. From that observation, it could be expected that particulars of wind effects can be lo¬ cated in this work. Exclusive of air barriers, a roofing technologist would not be disappointed in this work. Several times, the author had the courage to state certain behaviors of specific product types. The allega¬ tions were corroborated by exhaus¬ tive testing and are expressed by fairly straight-forward arithmetic re¬ lationships. Results on several occa¬ sions required plots on logarithmic scales to simplify expression of rela¬ tionships. The author refers to these relationships as “power equations” – his basis for the interpretation of data collected. The work appears to serve roofing audiences and reaches that end for polymeric one ply roofing; more¬ over, the work could assist research into the performance of other roof assemblies where an intense study of wind influence is the focal point. The book is founded in practical mathematics. It is for a practicing roofing technologist, by a technolo¬ gist. Forthose who dislike processing logarithmic equations to extract a message, the author continuously summarizes hidden meanings by an italicized conclusion. This attention to detail proved most helpful. The photos, figures, tables, graphs, and highlighted conclusions combine to make this a very worthwhile re¬ source. 12 Interface Nov/Dec 1993 Roof Consultants Institute Institute Announcements Planning to Take the RRC or RRO Exam Next Spring in San An¬ tonio ? The exams will be administered on Sunday, April 10, 1994. A re¬ view course for the RRC exam will be given on the preceding Satur¬ day.

SPRI president, Jim Mollenhoff, opened the meeting with the following personnel in attendance: Mr. Joe Hale, RCI President Mr. William Marcum, RRC, RCI Treasurer Mr. John Newark, RCI Executive Manager Mr. Bruce Wilby, SPRI Immediate Past President Ms. Ruth Warshaw, SPRI Executive Vice President This first liaison meeting provided both organizations the opportunity to President Joe Hale, Treasurer Bill Marcum, SPRI President Jim Mollenhoff, and SPRI Past President Bruce Wilby find time to relax during their liaison meeting. fully introduce themselves to each other and describe their respective or¬ ganizational structure, goals, and achievements. Spirited conversation easily led to the realization that both organizations could cooperatively work toward bet¬ terment of the roofing construction in¬ dustry. SPRI accepted an offer extended by RCI to be an exhibitor at RCI ’s upcom¬ ing national convention in San Anto¬ nio, Texas. Numerous topics were openly discussed which were of mu¬ tual interest. The meeting was ad¬ journed with both groups in agreement that a liaison should continue.

Host of the meeting was Tom Wallace of Northern Division, NA VFACENGCOM. Among the speakers and topics discussed were Robert Alumbaugh (NCEL Roofing Research), Robert Andrukonis (GSA Roofing Update), Andre Dejarlais (ORNL Roofing Re¬ search), Frank Hancock (COE Speci¬ fication), Orange Marshall (CERL Roofing Research), Walt Rossiter (NIST Roofing Research), Wayne Tobiasson (CRREL Roofing Research), and Al Knehans (EHSC Roofing Up¬ date). Invited guests included Tom Smith, AIA, RRC (NRCA), Joseph Jones (ARMA), and George Sievert and Roger Morrison (Polyurethane Foam Contractors Division), who made a presentation on uncoated graveled polyurethane foam. RCI was represented by Richard Horowitz, AIA, RRC, who was invited to present a brief overview of RCI and its programs. The committee was par¬ ticularly interested in both the RRC and educational programs and asked many incisive questions. In response, Mr. Horowitz stated that a list of all committee members would be sent to RCI headquarters and that each mem¬ ber would receive copies of Interface, RCI’s Membership Directory, and complete information regarding the RRC and educational programs, in¬ cluding the RRC application (which sets forth all requirements for becom¬ ing an RRC), and RRC Study Guide. About Our Members IT’S A GIRL! Congratulations to Le Ann Lankton, PE, on the birth of her baby girl. Ms. Lankton is with Firestone Building Products Company, and has presented seminars for RCI. When reading the November, 1993, issue of Professional Roofing, look for the feature column:Q&A. Terry Sim¬ mons, RRC, Deputy Director of Tech¬ nology and Research, recently published his first technical question and answer column. He will share the authoring duties with Mark Graham, Deputy Director of Technology and Research, who recently joined NRCA’s Technical Services Section. The Q&A column started in February of 1989 and has been authored by Tom Smith, AIA, RRC, Don Berg, PE, and Jim Carlson over the years. The expe¬ rience and expertise of the NRCA’s Technical Services staff makes for ex¬ cellent monthly reading on technical questions received by NRCA. 14 Interface Nov/Dec 1993 Roof Consultants Institute Executive Staff Meets With School Officials On October 31 through November 2, RCI exhibited at the trade show sponsored by the Association of School Business Officials (ASBO) In¬ ternational, a non-profit association of professionals involved in the manage¬ ment of school business services. ASBO serves its members as a primary resource for research, information, and professional services. Representing RCI were Joe Hale, Arthur Sark, Bill Marcum, and John Newark. They spoke with many offi¬ cials who religiously use roof consult¬ ants, convinced those who did not, and spread around our directories so that everyone could ensure that his/her roof consultant belonged to RCI. It is estimated that public schools nationwide will spend 34 billion dol¬ lars this school year on facilities and business operations, representing a hefty chunk for the construction indus¬ try. Colleges and universities will spend about 25 billion dollars on fa¬ cilities. RCI Participates in Reroofing Workshop At the invitation of the Oak Ridge National Laboratory (ORNL), RCI has joined a steering committee of roofing industry associations in the organiza¬ tion of a technical workshop on reroof¬ ing. RCI representative Christopher English, RRC, met with 13 other asso¬ ciations on November 16, and together they planned the workshop which will be held in May of 1994 at ORNL’s facilities in Tennessee. RCI will sponsor several presenta¬ tions, including the following: the reroof/ recover decision, practical considerations in roof design, and field evaluation of roofing. More details will be provided as they become avail¬ able. Proceedings of the May work¬ shop will be published and circulated. Some people literally “get into” (or, in this case, under) their work.

The event began on Thursday morning with a business meeting conducted by Bill Marcum and a few words of inspi¬ ration from President Joe Hale. The technical sessions followed, be¬ ginning with an overview of BURSI given by program director Ray Corbin. After his introduction, Ray presented a market share analysis of various roof systems and insulations, as well as a case study on the performance charac¬ teristics of inch perlite retrofit board. He also discussed issues affect¬ ing shingle performance, including weight of glass mat reinforcement, content of coating asphalt, and the im¬ portance of ventilation, including guidelines currently under considera¬ tion by ARMA which would recom¬ mend a iVi inch air space for composite insulated deck assemblies. Russ Snyder followed this discus¬ sion with an update on the activities of ARMA. Tom Campbell and Steve Kuhn, both of Schuller International, offered a new look at some important issues regarding fibrous glass felt, modified bitumen membranes, expansion joint covers, and metal fascias. The first day of our program con¬ cluded with a buffet dinner and table top exhibition. We thank our exhibi¬ tors fortheir participation and ongoing support of RCI. On Friday, Dr. Walt Rossiter Jr. of NIST presented an overview of his ongoing research into the performance of EPDM seams.

This – was the first Region time a region meeting had been held in the islands, and the turnout was gratifying: 48 people attend¬ ed. Moderated by Robb Smith, RRC, of Advanced Roof Technology, the sessions focused on personal experi¬ ences investigating hurricane-inflicted roof damage. Robb Smith, RRC Director Robb Smith began the meeting with a video presentation discussing the ori¬ gin of hurricanes which strike the east coast and illustrating the destructive nature of hurricane force winds. President Joe Hale, FRCI, of HDH Associates, provided background in¬ formation on FEMA building per¬ formance reports of hurricanes Andrew and Iniki and distributed these reports to the attendees. Having led the RCI Disaster Re¬ sponse Team investigations after An- Sam Huff, Mike Hickey, Phil Dregger, and Ed Keith faced an enthusiastic audience in Honolulu. drew, Sam Huff, RRC, of Huff Con¬ sulting Services, observed first-hand the remains of numerous commercial and residential buildings. He detailed his observations, emphasizing damage caused by rooftop mechanical equip¬ ment. Typically, HVAC units were not fastened in place and gravity was insufficient to resist the extreme wind forces of Andrew. With primary focus on the structural failings of typical residential construc¬ tion, Ed Keith, PE, of American Ply¬ wood Association, illustrated several reasons for widespread destruction. These were usually due to inadequate nailing of plywood sheathing and ab¬ sence of hurricane clips and other steel connections. Phil Dregger, PE, RRC, of Techni¬ cal Roof Services, addressed his per¬ sonal experiences investigating roof (See REGION SIX, page 18) SEMINAR ON CALIFORNIA LICENSING, INSURANCE, AND SAFETY TRAINING REQUIREMENTS A Region Six meeting took place on September 13 in El Segundo, Calif., which focused on the theme “How to Protect Your Company from Litiga¬ tion”. Ernie Orchard, of Orchard Roofing Consultants, began the ses¬ sions with an outline of the topics: licensing, insurance, and safety and training. David Orbach, Esquire, of Maguire & Orbach, outlined the requirements for “experts” and “consultants” who practice in California. He pointed out that before offering recommendations for repair and budgeting, state law re¬ quires the professional to be licensed. While a non-licensed expert can testify on right vs wrong, he can’t give recom¬ mendations for repair. Pat Riley, an insurance broker with Westland Insurance Brokers, outlined what he looks for when writing an insurance policy for a company and what can lead to cancellation of a pol¬ icy. He emphasized the need for safety programs which involve all em¬ ployees, documented attendance at safety meetings, and updated em¬ ployee files about safety -related warn¬ ings. Emie Orchard closed the program with an outline showing how to de¬ velop an Illness and Injury Prevention Program, as is required by California state law. He then offered recommen¬ dations on how to get and keep em¬ ployees involved in safety programs. A rather heated discussion followed on whether or not roofing consultants should be licensed contractors. The meeting concluded with Mr. Or¬ chard stating that if the consultant is neither a licensed architect nor engi¬ neer, he must be a licensed contractor in order to comply with California state law.a Nov/Dec 1993 Interface 17 Roof Consultants Institute (REGION SIX continuedfrom page 17) damage of resort properties on Kauai resulting from Iniki. Much of his fo¬ cus was directed toward the need to discern damage directly related to the hurricane versus damage which may have been developing as a result of pre-existing roofing and waterproof¬ ing conditions, such as splits in the membrane or cracks in the walls. The performance of tile roofing sys¬ tems was reviewed in a presentation by Mike Hickey, of Newport Fasteners. Mike discussed the pros and cons of the mortar set method common in Florida and compared it to mechanical fastening. He illustrated, as example, a tile roof on a building (located in Guam) which survived 190 mph winds of Typhoon Omar. On Tuesday, the Basics of Roofing seminar was presented with 18 people in attendance. Both meetings were well reviewed by those attending, most of whom had not heard of RCI Native Hawaiian Hut: Just One of the Enjoyable Sights of the Islands until recently. RCI has lately added to its ranks four members from Hawaii: Lance Luke, Bernie Lander, Howard Meechan, and Reno. Region Six plans to have at least one meeting in Hawaii annually. The next meeting is planned for Monday, March 21, 1994, in Salt Lake City, Utah. The topic will be tile roofing in snow country. ■ (REGION ONE continuedfrom page 16) levels of surface preparation on seam performance. Douglas Burch, also of NIST, fol¬ lowed with a discussion of moisture accumulation in walls and an introduc¬ tion to his new software “MOIST”, designed to predict heat and moisture transfer through construction assem¬ blies. The group then departed for a tour of the enormous NIST facility and a look at the varied construction re¬ search performed at the Center for Building Technology. The Registered Roof Observer exam was offered at this meeting to those whose applications were ap¬ proved, and seven brave souls stole away for a few hours to take this exam. We wish them well and look forward to many more RRO exams offered at region meetings. ■ The RCI Board of Directors Wishes You a Safe and Happy Holiday Season and New Year President Joe Hale First Vice-President Sam Huff, RRC Second Vice-President Arthur Sark Secretary Christopher L.

The objective of the TTU research is to obtain full-scale measurements of mean wind pressures and associated stresses imposed on metal edge flashings by natural wind. This data could then be used as a ra¬ tional basis for development of guide¬ line recommendations for metal flashing thicknesses, fasteners size and spacing, and cleat interlock de¬ tails. Thanks to recent pledges of finan¬ cial support from several other indus¬ try organizations and three flashing manufacturers, the research project is now fully funded. Initial wind tunnel pilot tests have already been per¬ formed to help determine locations for pressure taps for the full scale tests. The wind tunnel tests yielded some interesting data about how continuous cleats seem to influence the magnitude and distribution of pressure coeffi¬ cients behind the vertical face of the metal flashing, when compared to the influence of “discrete” cleats (clips). On October 13, 1993, the project’s steering committee met in Lubbock, Texas, to review the TTU full-size ro¬ tating field laboratory building and to select metal flashing configurations for testing. Five coping and “gravel stop” configurations, with different face dimensions and cleat configura¬ tions, were finally agreed on for full scale testing at both edge and “comer” locations. Field testing is anticipated to At Texas Tech University, Phil Dregger, of Technical Roof Services, Pleasant Hill, Calif, examines a mock-up metal edge flashing next to the wind tunnel at left (38 ft. long). Initial wind tunnel tests provided important information about location and spacing ofpressure taps for full-scale testing. begin in mid-November and to be completed in approximately six months, depending on favorable wind conditions at the site. Data analysis is expected to be completed in the fall of 1994. The TTU research project will be discussed further at the RICOWI meeting scheduled in conjunction with the 1994 RCI Convention in San An¬ tonio, Texas. ■ RICOWI Meets at Clemson The November 19, 1993, RICOWI meeting began with a tour of the Clem¬ son University Wind Engineering Laboratory and its new BRER-WULF (BRE Real-time Wind Uniform Load Follower) testing apparatus. The BRER-WULF apparatus includes a special “bi-polar” valve that allows ex¬ tremely rapid fluctuations of air pres¬ sure above and below a test specimen. This procedure can simulate the dy¬ namic forces associated with wind gusts whereas procedures presently Nov/Dec 1993 Interface 19 Roof Consultants Institute used by Factory Mutual and others are basically “static” in nature. Following the tour, reports of cur¬ rent wind related activities were given by several executive committee mem¬ bers and industry representatives. Highlights include: • The 1992/93 amendments to the Standard Building Code (SBC) clarify that membrane roof cover¬ ings should be designed to resist the full code prescribed wind forces. • Some lightweight insulating fill decks have been observed to fail by delamination within the fill mate¬ rials rather than by pull-out or pullthrough of base sheet fasteners. Mr. George Smith, with Factory Mutual Research Corporation, ex¬ plained that Data Sheet 1-48 will be revised some time next year to reflect this concern for installa¬ tions requiring Zone 3 securement (field uplift pressures greater than 45 psf). • A research program funded by the National Science Foundation at Texas Tech University is develop¬ ing a computer program to predict hurricane damage based on build¬ ing type and roof covering. • Changes to ASCE 7-88 are due out in 1995 (ASCE 7-95) and will in¬ clude a new wind speed map for “three-second” wind gusts. RCI’s Executive Committee Report focused on the newly revitalized Dis¬ aster Response Program and the strong emphasis given to wind considerations in RCI’s levels II and III education courses. RCI’s Disaster Response Program maintains the goal to obtain accurate weather data and post-hurri¬ cane performance data on pre-docu¬ mented buildings. Exciting new developments in the Disaster Re¬ sponse Program include: • A focus on roofs installed in ac¬ cordance with current standards. • Development of non-penetrating weather station mounting systems. • A cooperative agreement with State Farm Insurance Company to utilize selected buildings along vir¬ tually the entire Atlantic and Gulf Coasts. The next scheduled RICOWI meet¬ ing will be on April 9 and 10, 1994, at the RCI National Convention in San Antonio, Texas. ■ Information Central Still Growing Strong In the year and a half since its incep¬ tion, Information Central has ex¬ panded like a hot air balloon and taken flight. Members and non-members alike regularly call for information, and the information stacks up higher and higher on our shelves. But don’t worry, Headquarter’s floor space has increased, too, so there’s plenty of room for more material. What is Information Cen¬ tral? Information Central is a catalogued library of: • Manufacturers’ specifications and technical information • Building codes • Proceedings from meetings of various industry committees and associations • Interface articles • Published articles written by RCI members • Technical books and textbooks • Reference manuals • Business-related resource material This centralized index serves the in¬ dustry by providing up-to-date facts and resources on a variety of topics. Archival reference and cross indexing is also available to assist those who need information. How Is Information Central Accessed? Just call Headquarters. If we can’t answer your question right away, someone will get back to you. Anominal fee of $ 10 (more for non-members) is charged for requests involving re¬ search. Where Does all that Infor¬ mation Come From? Now for the pitch. All information comes from only one place: you sub¬ mit it. Headquarters acts as a clearing¬ house and data manager, but you provide the substance by sending us your old (new is fine, too) catalogs, journals, textbooks, codes, articles, photos, etc. Anything you consider valuable resource material will be wel¬ come.

Suffice to say, the meeting of individuals throughout the country who looked forward to generating something new was very exciting. By now, probably everyone knows the names involved with RCI. I look back at what I consider to be turning points in the evolution and growth of RCI, and I am genuinely honored and delighted to have been part of it. One of my fondest remem¬ brances was when RCI came of age in moving away from elitism and isola¬ tionism and, instead, went to a joining of the industry by expanding RCI membership to include industry, asso¬ ciation, and other classifications. Who of us will ever forget the tremen¬ dous fight on the floor of the conven¬ tion when RCI members dedicated themselves to the industry, instead of to individual desires? Who of us will ever forget Ben Hale’s recommendation for our first annual convention? It was a daring and bold step for which all of us are grateful to Ben and to those who fought so hard to bring the first con¬ vention to fruition. It was a truly ad¬ venturesome leap, which helped to put RCI on solid ground. We can all look back now on the CRC/RRC and the Educational pro¬ grams and feel a certain amount of pride. It was a commitment that RCI made to education and improvement of the industry. But it was certainly not easy. Again, do we all remember the floor fights at the convention where, once again, RCI members put aside their personal feelings and voted to make this test available to all members of the industry, whether consultant, roofer, manufacturer, etc.? Looking back, the floor fight was worth it, and I believe RCI’s commitment to excel¬ lence through education was never more manifested than in that lone de¬ cision. One of my personal and fondest memories was the time that Dick Canon asked if I remembered making a statement at a committee meeting years before, which freely translated, said that “RCI is a business and must be run as such.” I answered that I did remember that statement. He re¬ sponded that at the time he did not agree, but having watched the evolu¬ tion of RCI, he now thinks that, yes, it truly is a business and should be run (See ANNIVERSARY, page 22) The following letter, submitted by Robb Smith, RRC, was originally published in Western Roofing magazine as a letter to the editor. David Orbach wrote this letter in response to a Western Roofing ar¬ ticle, dated March, 1993, entitled “Roofing Consultants: When the Watch Dog Joins the Wolves, the Sheep Don ’t Stand a Chance. ” This article asserted that a few “bad wolves” in the industry gave rise to roof consultants, who, un¬ less regulated, may do more harm than the wolves. Reprinted with permission from Western Roofing. FROM OUR MEMBERS Saving for a Rainy Day As an attorney who specializes in construction litigation, including sub¬ stantial defect litigation, I was taken aback by the article bemoaning the proliferation of roofing consultants. I was even more surprised by the fact that this article was written by some¬ one whose company is based in Or¬ ange County, California, where sloppy roofing practices are nearly legendary. The proliferation of roof consult¬ ants, in my estimation, is the direct result of one thing: rain. During the past seven years of drought, the issue of roofing was relatively minor and the quality of roofs installed was left to the roofing contractor who operated with little supervision and worked from plans which were basically schematic in nature and from skimpy, if not downright irrelevant, specifications. Guess what? During the past two win¬ ters there have been more roof leaks in California, especially in Southern California, than probably in the pre¬ ceding ten years combined. Every contractor and insurer com¬ plains about the explosion in defect lawsuits, be it single family resi¬ dences, commercial structures, apart¬ ment complexes, or more frequently, condominiums and multi-family pro¬ jects. I believe it is safe to assume that if one removed cases resulting at least initially from water leaks, the defect litigation would be reduced by 50 per¬ cent overnight Possibly more. Had the roofs been properly designed, installed and maintained, most of those leaks (See RAIN, page 22) Nov/Dec 1993 Interface 21 Roof Consultants Institute (ANNIVERSARY, from page 22) like one. Again, we were looking at our own personal growth and the growth of this institute. In closing, I’d like to reference a statement made by Al Pacino in the movie The Godfather. “This is not per¬ sonal. It is strictly business.” In my opinion, it has become more evident over the years that, despite our individ¬ ual feelings, likes and dislikes, we have all grown into that axiom. With regard to RCI and its past struggles. floor fights, kibitzing, etc., this is now taken to mean that, “Gentlemen, this is not personal. It is strictly business,” and we are all looking toward the same goals: professionalism and excellence in this industry. I would personally like to take this opportunity to thank everyone for making possible the experience of RCI, its members, and its staff. I appre¬ ciate the privilege of having watched an institute grow and have a positive impact on the roofing industry. If I have one thought of which I am most proud and that best describes the vision of RCI, it is the fact that its members have taken the attitude of inclusion, rather than exclusion. The result has been the emergence of a strong institute. Very truly yours, Robert F. Martin, FRCI President, Roof Maintenance Systems (RAIN continuedfrom page 21) and subsequent litigation could have been avoided. I represent a number of roofing contractors. I rarely see a prob¬ lem with their work. However, on cases on which I have represented the owner, I have seen tom felt, improp¬ erly lapped felt, no felt, and nailing practices which are bizarre at best. I have seen actual testimony where a roofing contractor admitted under oath that the standard nailing practices in the industry differ depending on whether a city inspector is on site. This brings me to the issue of the relevancy and desirability of utilizing roof con¬ sultants on construction projects. If I were building a house, I would hire a roof consultant. I recommend to all my clients that they hire a roof consultant for any pro¬ ject which will affect the roof. First of all, architects do not spend much time designing the roof or contemplating water penetration issues. A good roof¬ ing consultant should review the plans, point out potential areas of concern including maintenance items, draft co¬ ordinated specifications for the roof, and sign off on both the plans and specifications. The consultant should be on site when the roof is being in¬ stalled and should photograph the ac¬ tual application on a continuous basis. The consultant should make sure that the various trades working on the roof are working in conjunction with each other and that the various applications are consistent with the plans and speci¬ fications. Should roofing consultants be li¬ censed? Maybe. It is probably too small a fraternity to warrant state li¬ censing. How to insure the roofing consultant knows what he or she is doing? I know some groups, such as the Roof Consultants Institute, of which I am a member and regional counsel, that have certification proce¬ dures. What I recommend for roofing consultants is what I recommend for any consultant: check references and qualifications. Make sure the consult¬ ant is insured and has some specific specialization which coincides with the project being considered. Will re¬ taining a roof consultant stop water leaks? Maybe. Maybe not. Will it cause more stress to the prime contrac¬ tor and roofing subcontractor? Some¬ what. That stress is nothing compared to the stress caused to the owner of the project who will have to live with the results of the contractor’s work. Until I see a fundamental change in the way roofing contractors perform their work, I will continue recommending to all my clients that they hire a roof consultant.

Perry R. Safran, Attorney With thanks to Michael J. Rizzi Perry R. Safran is a licensed contractor, realtor, and an attorney with Safran Law Of¬ fices, in Raleigh, North Carolina. Mr. Safran com¬ bines his cons t r u c t i o n expertise with his legal practice to of¬ fer a unique service. He is a registered lobbyist, a registered arbitrator, and sits on the Board of several industry associations. In addition, Mr. Safran teaches construction law at North Carolina State University. Michael J. Rizzi is a thirdyear student at the Campbell University School of Law in Buies Creek, North Caro¬ lina. He re¬ ceived his undergraduate degree from Bucknell University in Le¬ wisburg, Pennsylvania, and hopes to practice personal injury and workers ’ compensation law in North Carolina. If a contractor signs a contract, per¬ forms work, and improves the property without environmental contamination on his part, he is free from environ¬ mental liability, correct? Not under the current definitions of the federal statute Comprehensive Environmental Response, Compensation and Liability Act, (CERCLA) 42 U.S.C. §9607. Contractors need to know when they will suffer environmental liabil¬ ity. With CERCLA, many property owners are trying to find new angles of recovery against third parties such as contractors. When confronted with CERCLA clean up costs, many prop¬ erty owners will try to spread the costs to as many people as possible. This is where contractors must beware. The CERCLA definitions of “owner” and “operator” allow recov¬ ery from any person “who at the time of disposal of any hazardous substance owned or operated any facility at which such hazardous substances were disposed of.” The definition of “owner” is very broad. For example, if construction companies, lending insti¬ tutions, residential developers, etc. buy land previously contaminated by the last owner, they are held liable as “owners” under CERCLA. Even though the current owner didn’t cause the contamination, he is still the “owner” under CERCLA’s definition, and will be liable for cleanup costs. Current owners of any facility which releases or threatens to release a toxic substance are automatically liable. “Operator” is an equally broad term under CERCLA. A general contractor was recently held to be an “operator” where, during grading, contaminated dirt was pushed onto an existing con¬ taminated site without adding any new contaminants. By merely pushing around contaminants, the contractor fell under CERCLA’s definition of “operator” and was liable for cleanup costs. Homeowners have tried to hold con¬ struction companies liable under CER¬ CLA as “operators” when a third-party spill occurs on the land while the home is being built. For example, if, during construction, someone unrelated to the job releases a contaminant on the prop¬ erty, homeowners may try to hold the construction company liable as an “op¬ erator”, asserting that the contractor’s physical presence on the site is enough control over the property to be held an “operator” under CERCLA. But courts have limited the definition of “opera¬ tor” and dismissed these claims, be¬ cause the owner retains ultimate control over the land, even during con¬ struction, and could order the contrac¬ tor off the site. Contractors are not present continuously, only as light and weather conditions allow, and then only in the limited capacity of workers. Using this approach, courts have found contractors not to be “operators” under CERCLA. Contractors need to know exactly what risks they are taking when they sign a contract. They need to get “hold harmless” provisions written into the contract, or require the owner to pro¬ vide results of soil testing before be¬ ginning work. But, if the owner later becomes insolvent, the contractor may still he held liable for cleanup costs discovered later in the course of the project under CERCLA. ■ Nov/Dec 1993 Interface 25 Roof Consultants Institute ASTM TO DEVELOP EMERGENCY STAND¬ ARD ON ABATEMENT OF LEAD HAZARDS Subcommittee of ASTM E-6 on Per¬ formance of Buildings will meet Janu¬ ary 12-13, and March 20-23, 1994, to develop an emergency standard for en¬ capsulation products. Encapsulation offers a means of management that is generally lower in cost than abatement through removal. For more informa¬ tion, contact Carolyn Thompson at 215-299-5517. NEW SMACNA MANUAL The Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA) will soon publish the fifth INDUSTRY NEWS edition of its Architectural Sheet Met¬ al Manual. This revision includes new master roof plans keyed to figures, up¬ dated rainfall data, and expanded standing seam pan schedules. This edition also reflects more quality control in simplifications, prescrip¬ tions for detailing, and the addition of model specifications for regulating work. Recent independent roofing tests indi¬ cate that standing seam and batten seam custom-fabricated sheet metal roofs installed on solid plywood sheathing can withstand hurricane strength winds without blowing off or becoming damaged. This valuable data is now available in the Architec¬ tural Sheet Metal Manual. Contact SMACNA’s Publications Department at 703-803-2989. New Opportunity to Advertise to Lucrative Education Market! From 1993 to 1995, it is estimated that educational institutions will spend more than $3.5 billion on new and retrofit roofing. This represents a tre¬ mendous market for your services. Now you, as an RCI member, can tap into this market at a reduced cost. RCI has negotiated a special agree¬ ment with American School & Univer¬ sity that allows you to advertise each month to over 51,000 school adminis¬ trators and facilities nationwide at a ten percent reduction off the normal price. Your order will entitle you to a monthly listing, like the one shown at right, in the AS&U magazine.
