Durability & Weathering

For Envelope, Target Durability, as Well as Energy.

“As roof designers place more emphasis on LCA and cradle-to-cradle concepts, EPDM’s combination of low installation cost and lifetime economic value, durability, installation ease, design flexibility, and recyclability make it an economic and sustainable choice.”

The EPDM Roofing Association retained the services of Jim D. Koontz & Associates, Inc. to perform laboratory testing on 81 test targets provided by the association. The targets varied in age and substrate. The samples were impacted with ice spheres… Read More

“The roof is becoming a more complex, challenging, and important component of any number of buildings, but especially so for schools and universities. The current economic climate, the growing presence of energy producing systems (solar panels or wind turbines), the… Read More

“Based on field and test data, it is clear that EPDM roof membranes outperform other roof systems in terms of hail protection. In tests including simulation of hail up to three inches of diameter, EPDMroofing membranes did not suffer membrane… Read More

“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

“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

“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.”
