It’s just a roof, right? And buildings or designs never change. Not quite. Roofing plays an important role in protecting the building from the elements as well as insulating to preserve occupant comfort. With a wide variety of roof systems used on commercial buildings, selecting low-slope roofing assemblies can be complicated. Starting with four unique roofing case studies to review design team considerations and decisions, we will ask the infamous question “What if?”. You will leave this interactive session with a better understanding of best practices in low-slope roof system design and selection, including ways to establish air tightness, reduce moisture intrusion, and lower the overall risk of failure to ensure you are able to appropriately evaluate design change requests on your next project.
- Understand how design parameters, such as building and rooftop use, as well as climate and building location influence roof design decisions.
- Recognize the basic components of low-slope roofing including different insulations, coverboards, and membrane types.
- Differentiate between attachment methods of roofing systems including insulations and membrane attachment options.
- Utilize case studies to understand how decisions made during the design process can impact the performance of the roof.
