Abstract
Single-ply rubber membranes, based upon ethylene-propylene-diene terpolymers (EPDM), have been used as roofing membranes for over 30 years. A summary of the pysical properties of aged field samples was reported in 1991. Under the auspices of the EPDM Roofing Association, thissubject will be revisited and extended to include the performance of aged EPDM membranes in place for the past 20 to 25 years. Roof systems by various manufacturers will be sampled in a variety of locations. An indepent laboratory will evaluate the samples to determine elongation, tensile strength, and tear resistance of the aged membrane. The impact of the results on the actual field performance and long-term stability of EPDM roofing membranes in various climates and system configurations will be discussed.
