Adhesives in Single-Ply Roofing Systems
A Sticky Situation in Single-Ply Roofing
Sponsored by GAF | Siplast | Presented by James Kirby, AIA, and Kristin Westover, PE, LEED AP
Webinar On-Demand
Roof systems are a complex part of building enclosures with many functions and components; adhesives are often used to hold the components together, while offering improved installation speed and long-term performance benefits. This webinar discusses roofing adhesives in general, as well as providing specifics based on membrane type. Examples will demonstrate how roof system design installation factors are used to meet key project goals: system design, energy-efficiency, wind resistance, resilience and schedules/budgets.

LEARNING OBJECTIVES
- Determine what it means to adhere a roof system, including review of adhesive types.
- Discuss material and substrate limitations when adhering roof assembly components, including vapor barriers, insulation, coverboard and single-ply membranes.
- Recognize key roof system performance attributes of adhered roofs, such as the effect on wind uplift, impact resistance and air intrusion.
- Explore case studies of adhered and mechanically attached roof assemblies, including R-value reductions due to thermal bridging, material costs and overall energy efficiency of the different assemblies.
