I’ll admit it; I significantly overlooked some important technical complexities of reroofing during some of my first projects. Luckily, I’ve worked with experienced colleagues and competent contractors. After working on dozens of reroofs as the engineer of record, I’ve learned a lot. This presentation will focus on case studies from reroofing projects, highlighting a technical aspect of the project that can be helpful to anyone working on their next reroofing project. The projects reviewed are extensive and range from sloped shingle roofs to low-slope membrane roofs to flat lock copper.
1. Learn key code requirements that should be addressed during reroofing, such as venting, thermal issues, increased structural loads, and existing deck condition.
2. Understand peripheral reroofing considerations such as public safety during construction and adding fall protection anchors.
3. Identify critical items to include in the design documents to help reduce omissions and assist contractors with accurate information for bidding.
4. Review examples of how design decisions can impact performance and construction cost.

What appeared to be a simple reroofing job at a 51,000-square-foot institutional facility turned into four years of research and design to determine the best possible solution.
The existing roof on an institutional facility in California’s Central Valley had reached the limits of its existing useful service life and had several leaks. The roof contained thousands of penetrations, including façade access davits, guardrails, guard walks, solar hot water heaters, vents, communication lines, etc. The original roofing system consisted of liquid-applied roofing in an inverted roofing membrane assembly (IRMA). The inherent function and conditions of an institutional facility presented a long list of restraints. The facility was overcrowded and contained a laundry facility, health care units, kitchen, locker room, exercise facilities, and court room. Restraints included: odor, delays due to security clearances, number of penetrations, schedule, and costs.
Several performance mock-ups were done to test for removal of the existing membrane, adhesion, and odor. Different roofing systems were tested, including poly-methyl methacrylate (PMMA), polyurethane, and styrene-butadiene-styrene (SBS) modified-bitumen roofing. Several issues were discovered during the mock-ups, including vapor drive and dust control. Without performing these mock-ups, the project could have been mired in delays and change orders.
This presentation will present the case that mock-ups, surveys, and investigations are essential for any remedial work. With the increasing need to renovate and convert existing buildings, mock-ups become more and more necessary. Spending time and money upfront will help to save time and money in the future.
1. Understand to identify and prioritize constraints on a project that are essential to design.
2. Understand various test methods for liquid-applied roofing application.
3. Understand how mock-ups can be utilized to verify or determine existing conditions for remedial projects.
4. Understand how mock-ups can help identify unknowns that can lead to costly change orders.

Since the early 2000s, the building industry has been evolving to include more stringent provisions relative to sustainable construction. In its infancy, most of this trend focused on energy-hogging MEP systems. However, as MEP systems have become more efficient, the “green” focus has expanded to include other methods of achieving “better” buildings, including green and cool roofs. The trend of cities adopting requirements for green and cool roofs (and all the associated provisions that come along) has a major effect on the way the industry designs, constructs, maintains, and replaces roofing systems. Understanding the general trends associated with these changes—including the spread of the adoption, the influence of the public on this process, and the incorporation of other technologies, such as solar and rainwater catchment—is imperative for proper maintenance and replacement of existing roofs. However, as these trends emerge, they also bring to light a serious question of whether our current strategies are truly sustainable at all, or if a more “back-to-basics” approach to roofing sustainability might serve buildings better. The lessons learned in the continuing evolution of Denver’s Green Buildings Ordinance provide numerous examples of how these trends affect our industry, and ways that well-intentioned “sustainability” provisions can have unintentional consequences. A clear understanding of these concepts will enable us to provide the best service to our communities, and to become proactively involved in shaping the future of our industry.
1. Understand the basic history and general adoption trend of green and cool roof provisions.
2. Learn the current trends accompanying the adoption of green and cool roof requirements, such as the expansion of the adoption, the involvement of the public, and the incorporation of solar and rainwater catchment systems in these requirements.
3. Evaluate the true sustainable merits of green and cool roof requirements.
4. Learn some “back-to-basics” sustainability approaches which can be applied successfully in all climates to improve our built environment

The Concha Townhomes were built in 1987, and concrete roofing tiles were installed. After 32 years of exposure to harsh climate conditions, there were numerous leaks. In addition, the roof tiles had been discontinued. The homeowners’ association (HOA) needed to decide if to continue repairing or if it was time to replace the roofs. Multiple units were inspected to determine the overall condition of the roofs. The tile was good, but the sub-system was at the end of its life cycle. Reroofing was the best option. New roofing materials and color options were reviewed, and the HOA decided on Class IV hail-impact-rated concrete roofing tile, and a scope of work was created. The emphasis was in understanding the failures and in adopting changes for better long-term performance. Four roofing contractors were selected and sent requests for quotes (RFQs) and a scope of work. A contractor was chosen, and the project was started. The project took six months, and final punch items were completed.
1. Understand the existing conditions repair history, roof tile / system components, and current issues with the system to assess repairability or replacement options.
2. Understand system evolution and presentation of options to a HOA with respect to life cycle expectations.
3. Understand project administration of roof replacement projects, including third-party inspections and field issue resolution.
4. Understand the project close-out process and closing document packet containing warranties, permits, etc.

Window replacements and retrofits represent a significant investment, and, therefore, it is key to decide on the right strategy and to provide the owner with accurate information on performance and options. Before you replace or retrofit windows, many factors need to be carefully evaluated. The most important first step is understanding the owner’s reason for wanting to replace or retrofit windows. For example, if improving sound control is the primary reason, then glass selection for the new window or a retrofit storm sash are the critical factors to consider. If water intrusion is the main complaint, then it is critical to understand whether the water intrusion is related to the window only or the surrounding wall claddings or flashing. The second most important step is evaluating the existing conditions of the windows and its integration and flashing with the surrounding wall claddings. These first two critical steps will then help you advise the owner on appropriate replacement and retrofit strategies and options, which include window types and installation options. This presentation will cover this evaluation, design, and installation process and explain several key energy efficiency upgrades that can be considered at the time of window replacements for low incremental cost. This presentation will also show example case studies of what can go wrong when these steps are not followed.
1. Identify the owner’s reasons for window replacement or retrofit, including whether to address water intrusion, condensation, air leakage, thermal comfort, energy performance, functionality of window sizes, aesthetics, acoustics, or security.
2. Describe the steps in a condition assessment to determine performance of existing windows and the integration with surrounding wall claddings and flashings.
3. Summarize window replacement and retrofit options, including punched windows, ribbon windows, reglazing options, and installation options.
4. Explore with the owner energy efficiency retrofit options for both windows and surrounding claddings that can be performed at the time of window replacement for low incremental cost
