Single-Ply Roof Systems: More than Meets the Eye
A roof is more than the surface that keeps water out of buildings; it’s the first line of defense from the elements, whether it’s rain, snow, wind, hail, heat, or sun. Roof systems are a complex part of the building enclosure with many components that serve as a means to control water, air, vapor, and heat transfer. This presentation will review how changes in energy codes and local ordinances have shifted the paradigms in what is considered best practice when it comes to specifying energy-efficient and durable single-ply roof assemblies. We will discuss the different types of roof membranes, coverboards, attachment, insulation, and vapor barriers used in single-ply roof systems. To provide context, we’ll review several project examples to demonstrate the best practices and tools available to designers who may be new to single-ply roof assemblies or cool roof requirements.

The Building and Roofing Science team offers regional expert building enclosure collaboration through design, specification, and educational support for customers of GAF and Siplast, both Standard Industries companies. GAF is North America’s largest roofing manufacturer with more homes and businesses in the U.S. protected by a GAF roof than any other product. Siplast, a leader in building enclosure systems, offers a portfolio of advanced, high-performance SBS-modified bitumen, PMMA liquid-applied, PVC KEE, lightweight insulating concrete, wall air & water barrier systems, and amenity/vegetated systems.
LEARNING OBJECTIVES
Evaluate the effectiveness of major types of single-ply roof systems to meet the requirements for cool roof building codes and achieve improved energy efficiency. Understand when to specify the different types of roof membranes, coverboards, attachment/adhesive, insulation, and vapor barriers used in single-ply roof systems. Identify how the performance of single-ply roof systems can be enhanced when considering sustainability, energy efficiency, wind uplift, puncture resistance, and ease of repairs. Apply examples of best practices and tools to assist in designing durable and cost-effective roofing assemblies.
