The EPDM Roofing Association has initiated a field-based research study designed to improve scientific understanding of the long-term performance of EPDM membranes and explore methods for estimating their remaining service life in commercial roofing systems. The study focuses on EPDM membrane samples from commercial roofs that have been exposed to decades of real-world environmental conditions. This approach incorporates field-aged materials that reflect actual in-service performance, providing an opportunity to evaluate the characteristics of membranes after years of natural aging and compare them with membranes subjected to accelerated aging and weathering. Collected samples will undergo laboratory testing in their as-collected condition … Read more
