INTERFACE Newsletter of The Roof Consultants Institute #107 April 1985 RCI NATIONAL CONFERENCE SECOND ANNUAL RCI NATIONAL CONFERENCE It has been two months since we concluded the events of our Second Annual RCI National Conference in New Orleans; however, many of the ideas, philosophies, and projects committed to at this conference will have an effect on this industry for many years to come. Not only has our overall association membership increased dramatically this past year, but the attendance at our conference was also markedly increased, with members attending from all regions from coast to coast. In addition to our supportive members, we were also fortunate to have all but one of our newly formed Board of Regents in attendance with us at the conference. A special thanks to Chairman Dr. Herbert Buschi ng and all the Regent Members for their time and valuable input at this conference. Once again Bob Phillips and Bill Correll are to be complimented on an excellent job of organizing this event for us. We wish to thank our Associate Members for their support of RCI, and a special thanks to those firms and representatives who made presentations to our group during the technical up-date sessions at this years conference. Last, but not least, we would like to thank John Karolefski, Editor of RSI Magazine, for taking time out of his busy schedule to address us on the subject of “An Overview of the Roofing Industry”. On a personal note I would like to take this opportunity to once again thank everyone for all their time, energy, and support in helping to make the RCI a reality. A very special thanks to Dick Canon, Bob Phillips, Mike Kelleher, and Bill Correll for their unselfish and total commitment to RCI by serving terms as our Executive Officers. As past President of RCI, I wish to extend my congratulations and best wishes to our newly elected Executive Officers and to our newly appointed Regional Directors. I pledge my continued support to RCI in my new capacity as Board Member, and I appeal to all of you to become more active in RCI this year. The future of RCI depends on all of us, and the future of our roof consulting industry depends on RCI! ROBERT W. LYONS, immediate past President RCI.

JEFFERSON SCOTT, Indianapolis, Indiana Region FIVE: FELIX L. GEORGE, San Diego, California A MESSAGE FROM THE PRESIDENT In speaking with a well known Roof Consultant recently, I asked if he would be interested in joining the Roof Consultants Institute, RCI. His answer 2 RCI Interface, April 1985 was provocative. He stated he was flattered to be asked to join the RCI but that his firm had discussed the possibilities and had determined that joining would serve them no purpose; it would not benefit his company. He went further and stated that they had concluded that it may even jeopardize or hurt their company. It is a tragedy when an organization, regardless of its size or longevity, is met with such opposition. RCI has been confronted with this reaction from several companies and individuals. These companies and names are some that we have heard of for years. Names that we have established in our minds as the experts, the epitome of a “Roof Consultant”. I thought it was interesting in my discussion with both this and another fine gentleman that neither had attended the Roofing Industry Educational Institute presentations. R.I.E.I., founded and directed by Richard Fricklas, has information pertinent to all individuals involved with roofing. It makes no difference whether you are a fledgling or whether you are an old veteran of consulting. We all need information. Information is the seed that grows the fruit of our business. Failure to accept this information is to cut-off the life source. A man who thinks he has all the information he needs about roofing is fooling himself. That’s not to say that individual is not intelligent, but he is not in touch with reality. I have yet to speak to a consultant, a manufacturer, a roofer, or an owner, regardless of his position or place within the roofing construction business, who has not taught me something. I have never been so full of knowledge that I could not accept more. Perhaps I’m an “Anomaly”. An anomaly is something that differs from all else around it. Maybe I am the only one who continues to gain information from those with whom I am involved but I think that perhaps the anomaly is the person who thinks he has all the information he will ever need and needs no more. It’s great when people have reached the plateau in their career that they can look down upon those below them who know less and, believe me, I look up to many of those individuals. But it seems to me that it would be a tragedy of our profession if we only look down, and not across or up. We all need to look up, to look across, and to look down for information. I think I can say with complete confidence and honesty that despite of all my ignorance, on occasion I have been able to convey some information, and some experience to those who have been in business for 20, 30, or 40 years; information and experience that they have not yet gained. Are there any among us who know everything? Are there any among us who know nothing? Again, I don’t think so. We are a blend of our knowledge and our experiences. The Roof Consultants Institute is the melting pot for information for the roof consultant. The invitation is open to all. The position of the gentleman who stated that it would not benefit his company, (it may even jeopardize his company) is missing the opportunity to be a vital part of progress. The best way I know to fight the war of ignorance is to establish an organization, develop regulations, train the troops, disseminate the information, and then attack our common enemy, ignorance. Such is the purpose of the R.C.I. to the professional roof consultant. As we enter our third year we have established a goal of recruiting 75 new members in 1985. That will require each of us to aggressively seek out new members, many of whom may be our strongest competition. As we grow in numbers we will also grow in strength, and hopefully wisdom. Our Board of Regents is committed to assist us in our venture and to guide our efforts. Our five Regions are now, for the first time, organized and gaining momentum. Let me urge you to become an active participant on committee assignments. It is imperative that we move forward professionally in ’85 and impress RCI on the minds of Owners and others as a professional institute founded to assist them through its organization. .Who needs R.C.I.? – you, the Professional need it! And R.C.I. needs you! “BE A PROFESSIONAL” (The following is an abstract of the presentation made by Dr. Herbert Buschi ng, Chairman RCI Board of Regents, at the RCI Annual Meeting in New Orleans, February 1985). Congratulations are in order to members and Regents of the Roof Consultants Institute. The formation and growth of RCI is a tribute to the founders and officers who devoted so much time and effort to wrestle with concepts and administrative structure. Those of you at the head table have, I know, invested a great portion of the past year in planning for this annual meeting. To all RCI members – welcome to the annual meeting! Accept the challenge to make the Institute a more professional and persuasive voice in roofing technology. There is ample opportunity for leadership and I hope each of you here this evening will assist with growth and maturation of the Institute during 1985. Be active in your association. You will contribute and receive benefits in direct proportion to your activity. The technology and practice of roofing is changing rapidly. The roof is the only portion of the building that requires major rehabilitation periodically. That period may be 15-20 years or, unfortunately, it may be less than 10 years. The proliferation of products for low-slope roofing compounds the difficulty of dealing effectively with the large number of products and problems. As consultants, you often oversee the demise of the old roof as well as the specification and construction of a new one. Hence, you serve as both undertaker and pediatrician. There is ample opportunity to improve the U.S. inventory of approximately 1200 square miles of low-slope roofing. There should be well-defined responsbilities and liabilities for roof consultants. The initials of this Institute – RCI – remind me of my responsibilities as an instructor in a land-grant university where our efforts encompass Research, Continuing Education, and Instruction. For the Institute, I propose that RCI stand for (especially for this evening) Responsibility, Competence, and Integrity. To be a professional in any field requires a good measure of each of these characteristics. Acting responsibly, competently, and with RCI Interface, April 1985 3 integrity is what professionalism is about. The professions normally have education requirements, certification of competence through internships and examination, requirements for continuing education, and a code of ethics. RCI members have made good progress this year, it seems, in addressing increased responsibility, competence, and integrity. The agenda of the Regents meeting (reprinted elsewhere in this issue) has been directed to improve the competence, utility and visibility of RCI. Hopefully, several of the suggestions made by the Regents can be initiated and completed during the coming year. RCI programs should assist in increasing competence of members and ultimately benefit materials producers, roofing contractors, and building owners. Perhaps one of the most important facets of your professional life and your contact with clients is your communication skill. It is a reflection of your responsibility, competence, and integrity. In the university, our industrial advisory boards all recommend that we require engineering students to take technical writing and, if possible, public speaking. Requirements for being technically competent are misdirected if our product, the students, cannot communicate effectively. Likewise, the need for practicing communications skills continues throughout your careers. Your letters and reports are perhaps your most important product. Let us learn this evening from an expert – columnist James Kilpatrick. He has provided some brief rules for workers in the “carpentry of words”. He provided these rules for student editors; however, these rules are useful for RCI members too!! Here is Mr. Kilpatrick’s advice. “1. Be clear . This is the first and greatest commandment. In a large sense, nothing else matters. For clarity embraceth all things: the clear thought to begin with: the right words for conveying that thought: the orderly arrangement of the words. It is a fine thing, now and then to be colorful, to be vivid, to be bold. First be clear. 2. Love words, and treat them with respect. For words are the edged tools of your trade: you must keep them honed. 4 RCI Interface, April 1985 Do not infer when you mean to imply; do not write fewer, when you mean less than. Do not use among, when you mean between. Observe that continually and continously have different meanings. Do not write alternately when you mean alternatively. Tints are light, shades are dark. The blob on the gallery wall is not an abstract. Beware the use of literally, virtually, fulsome, replica, many-faceted, and the lion’s share. Pinch-hitters are something more than substitutes. Learn the rules of that and which. When you fall into the pit of “and which,” climb out of your swampy sentence and begin anew. 3. Asa general proposition, use familiar words. Be precise, but first be understood. Search for the solid nouns that bear the weight of thought. Use active verbs that hit an object and do not glance off. When you find an especially gaudy word, possessed of a gorgeous rhinestone glitter, lock it firmly away. Such words are costume jewels. They are sham. 4. Edit your copy; then edit it again; then edit it once more. This is the hand-rubbing process. No rough sand-papering can replace it. 5. Stri ke the redundant word. Emergencies are inherently acute; crises are grave; consideration is serious. When you exhort your readers to get down to basic fundamentals, you are dog-paddling about in a pool of ideas and do not know where to touch bottom. Beware the little qualifying words; rather, somewhat, pretty, very. As White says, these are the leeches that suck the meaning out of language. Pluck them from your copy. 6. Have no fear of repetition. It is better to repeat a word than to send an orphan antecedent in its place. Do not write horsehide, white pellet, or the old apple when you mean baseball. Members of City Council are not solons; they are members of City Council. If you must write banana four times, then write banana four times, nothing is gained by three bananas and one elongated yellow fruit. 7. If you cannot be obviously profound, try not to be profoundly obvious. Therefore, do not inform your reader that something remains to be seen. The thought will have occurred to him already. 8. Strive for a. seasoned perspective. True crises come infrequently; few actions are outrageous; cities and economies are seldom paralyzed for long. A two-alarm fire is not a holocaust. Not much is imperative or urgent; still less is vital. To get at the size of a crowd, divide the cops’ estimate by 3.1416. 9. Style depends in part upon the cadence of your prose. Therefore, 1isten to your copy with a fine tuned ear. In the prose that truly pleases you find that every sentence has an unobstructive rhythm that propels it on its way. With a little re-arranging you can keep the rhythm going. But do not do this always; you may sound like Hiawatha. 10. Beware of long sentences; they spread roots that tend to trip the reader up. The period key lies nicely on the bottom row of your machine, down toward the right-hand end. Use it. Use it often.” With more attention to effective communications, RCI members will serve themselves and the Institute well. I wish you success in your ventures this year and hope you will, with new members, attend the next RCI meeting. In the meantime, practice your improved communications through active involvement on an RCI committee. Enjoy your technical and social functions in New Orleans and Godspeed on your trip home.

The varied and current technical input of the Board of Regents will assist RCI in maintaining itself in the forefront of sound, state-of-the-art technology relative to the Roof Consulting Industry. METAL ROOFING – (Part I) Contrary to many opinions, the concept of metal roofing systems is not new. In fact, the practice of sheathing a roof surface with metal cladding is known to have occurred on the European continent somewhere around the Renaissance Period. Metal roofing has been successfully used for many years in the United States. Colonial outhouses, servant’s quarters and farmhouses were protected from the elements by panels of sheet metal materials as far back as we are able to reconstruct the heritage of rural America. After its initial introduction into the United States, metal roofing seems to have undergone an excruciatingly 6 RCI Interface, April 1985 slow, but progressive metamorphosis. My observations prompt me to categorize metal roofing into two rudimentary, but useful classifications. First , the copper family including the softer, light-gauge sheet metals such as cold-rolled copper, soft copper, lead coated copper, etc. By far the most popular of these materials has been cold-rolled copper. Second , there are the pre-formed metal panels of various profiles, consisting of ferrous materials such as galvanized iron or steel with factory applied finishes. Stainless steel and aluminum materials appear to be cross-linked somewhere in between these two categories, depending upon whether or not they are extruded, pre-formed or flat sheets. Please understand that I am not attempting to develop any industry standard. I merely use these groups for my own convenience. COPPER . Soft-metal roofing, such as copper, appears to have received more favorable consideration through the years with regard to usage. Psychologically there may have been an association between copper roofing materials and the metals used by early European artisans for statuary and jewelry. However, I believe that these softer metals most likely appeared within early roofing systems because of their familiarity, workability and availability. Presumably due to their widespread usage throughout the Renaissance period, they have become associated with classic Architecture to a degree which has accorded them a great – deal of respect and recognition as a superior and prestigious roofing material. Copper roofs have been used in this country since Colonial times, on such impressive structures as Christ Church in Philadelphia, Pennsylvania. Built in 1787 it has the reputation of being the oldest known copper-roofed church in America, constructed only eleven years after the American Revolution. Heavy copper sheet was commonly employed for early roofing installations due to the fact that thinner materials were not available. Copper rolling techniques had not yet advanced to the present efficiency which now permits copper sheet to be manufactured in extremely light gauges. In addition, we have learned that placement of expansion joints at proper intervals, determined by the gauge of the metal and the shape of the section, will relieve stress in the metal created by thermal expansion. This will result in the reduction or total elimination of buckling. Working with light-gauge metal roofing requires a degree of careful attention. Even the practice of soldering two pieces of metal together should be given careful thought. The most commonly used material to join together sheets of light-gauge metal is solder. Solders that melt at temperatures of more than 800 degrees Fahrenheit should not be used for light-gauge sheet metal work. Ideally a solder of 50% tin and 50% lead, or 60% tin and 40% lead should be used. Solder is a weak alloy. It therefore possesses the strength to make a joint or seam as strong as the metal itself when used with copper up to 20 ounces in weight. However, when working with copper in excess of 20 ounces, solder should only be used as a waterproof ing medium – not as a structural element. Under such circumstances, the strength of a joint should be obtained mechanically. Whenever I observe a soldering failure, I immediately look at the design of the joint, and then question the composition of soldering materials. Last year, my firm was involved with a sixteen building campus project. Each building was shaded by structural overhangs which were affectionately referred to as “eyebrows”. An extremely complicated assembly resulted where the “eyebrows” adjoined various roof perimeters. Lead-coated copper was used as a sheathing over plywood and a significant number of the lead-coated copper panels had begun to buckle and deform. To illustrate my point I quote one excerpt out of our report concerning this problem. It said, “In our opinion, unilateral buckling of lead-coated copper throughout the entirety of this intricate and complex design is largely attributable to the utilization of sheet metal materials with inadequate weight and temper. Although absence of a sufficient number of transverse joints has admittedly contributed to buckling, the wide-spread existance of this undesirable condition in virtually every type of lead-coated copper configuration RCI Interface, April 1985 7 at each building has served as convincing evidence that a heavier gauge should have been required for all lead-coated copper sheet metal used to construct typical beam box covers and coping panels at this project”. On the above project inspection revealed that the lead-coated copper sheet metal selected for use at this project was 16 ounce cold-rolled sheet copper, conforming to ASTM B-101, Type I, Class A. Through a hot-dipping process, approximately 6 to 7 1/2 pounds per one hundred square feet of lead surfacing was laminated to each exposed face of copper sheet. It is possible that this hot-dipping application may have diminished the original temper of the copper. In practice, it is not unusual to find lead-coated copper being specified into a heavier weight increment than might have otherwise been specified for cold-rolled copper sheet metal. For example, if 16 ounce cold-rolled copper is considered adequate for a particular installation, it would not be surprising to find 20 ounce lead-coated copper material specified for a similar application. Generally, the practice of specifying a heavier gauge for leadcoated copper is to compensate for an anticipated loss in temper as a result of hot-dipping during the lead coating process. Even 20 ounce lead-coated copper sheet metal would not have proved sufficient for the design requirements on the above project. Due to the fact that numerous coping panels and beam box covers are generally more than 24 inches wide, further complicated by the thermal and structural dynamics which are involved at these buildings, we believe that 24 ounce lead-coated copper would have only proved minimally adequate, and that 28 ounce material should have actually been specified. Even with all of its particular idiosyncracies, there is not the slightest doubt in my mind that soft, light-gauge metal roofing will remain one of the most desired and sought-after materials for any roof construction requiring the very best performance with regard to weathering and aging. My observations indicate that no other roofing material in common usage can even approach the service life of copper. When designed and constructed correctly the initial investment usually proves to be the first, and essentially the last, cost for roofing. When life-cycle costing and salvage value are taken into consideration over a protracted period even the economics of this roofing method become very attractive. A new generation of highly intellient and sophisticated architects and designers has grown up. This New-Breed, as well as some of the Old-Guard, are currently producing outstanding innovative designs that utilize soft, light-gauge metal and pre-formed metal panels. The contemporary Architect, Engineer, Designer, Consultant and Roofing Contractor would be well advised to begin paying serious attention to this facet of the roofing industry. In my opinion, metal roofing represents a methodology whose time has not only come, but has been long overdue. (Note: the above is Part I of an article written by D B.
