The discussion reviews the author’s experience from hail events of all magnitudes. Roof types explored herein are not all-inclusive but are instead repre­sentative of the author’s frequency of expe­rience” Author: Lyle D. Hogan… Read More

RSI: Evaluating Ballasted Single-Ply Roof Systems

“Stone-ballasted membranes constitute about 10 percent of all newly constructed built-up and single-ply roofing systems, and many older systems continue to perform well in the low-slope roofing market. Unfortunately, in their zeal some structural engineers have confused the smaller and lighter pea gravel used on built-up roofs (BURs) for fire and weather protection with the… Read More
