Technical Bulletin 1 on EPDM Continued Performance
“EPDM (ethylene propylene diene terpolymer) rubber roofing membrane has been an appealing choice of the low-slope commercial roofing industry for over 40 years, with more than 500,000 warranted roof installations using 20 billion-plus square feet. Annually, EPDM accounts for over 1 billion square feet of new roof coverings in the United States, and is the most frequently used roofing material in the marketplace. Building Design and Construction magazine and the National Roofing Contractors Association (NRCA) confirmed in their 2002-2003 market surveys that EPDM continues to be the number one roofing choice of architects, roof consultants and contractors for both new construction and replacement roofing projects.”
