“This article is offered as a proposal for uniformity in the assessment of what actu­ally constitutes hailstorm compromise to various roof types. The discussion reviews the author’s experience from hail events of all magnitudes. Roof types explored herein are not… Read More

“In 1978, the California Energy Commission (CEC) established the Energy Efficiency Standards for Residential and Nonresidential Buildings in response to a legislative mandate to reudce the state’s energy consumption. These standards, which became known as Title 24, are updated periodically… Read More

“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… Read More

“Since the EPDM Roofing Association (ERA) was founded in 2002, it has sought to educate the construction and roofing communities by providing current, accurate data; technical informational and educational forums to discuss the characteristics and benefits of EPDM roof systems…. Read More

One of the unique attributes of EPDM is its ability to be easily repaired and restored – an attribute never seen before in the roofing industry. In some situations, when system enhancements are incorporated, the aged roof system is restored… Read More

“Selecting the most appropriate roofing system for a particular structure must always be approached carefully, but when the structure is located in the hail belt of the United States, there are additional considerations.”  

On the basis of the results of the study, the useful life of correctly made EPDM roofing membranes may be evaluated as clearly over 50 years under Central European climate conditions.  

The results obtained in this study confirm the outstanding field aging performance of EPDM membranes. The tensile strength and tear resistance data obtained for both ballasted and exposed roofs exceed the ASTM D 4637 specifications new and heat aged membranes… Read More

“In spring 1995, a group of roofing professionals from around the world with expertise in roof system design, roofing forensics, material manufacturing and material research convened in Brussels, Belgium, to discuss an emerging idea within the roofing community—sustainability.”  

Advances in seaming, fastening technology improve EPDM installation.
