• EPDM is an extremely durable synthetic rubber roofing membrane  (ethylene propylene diene terpolymer) widely used in low-slope buildings worldwide. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas. EPDM is available in both black and white, and can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specially formulated tape.

    The EPDM (ethylene propylene diene terpolymer) rubber roofing membrane has been an appealing choice of the low-slope commercial roofing industry for over 40 years. EPDM continues to be a top choice of architects, roof consultants and contractors for both new construction and replacement roofing projects.

    The greatest test of any construction material is how it performs under actual field conditions. Forty years of empirical experience in field applications has shown EPDM to have the roofing industry’s longest average service life. Characteristics that contribute to this superior overall system performance include:

    • Cyclical membrane fatigue resistance
    • Proven hail resistance
    • High resistance to ozone, weathering and abrasion
    • Flexibility in low temperatures
    • Superior resistance to extreme heat and fire
    • Thermal shock durability
    • Ultraviolet radiation resistance
    • High resistance to wind damage

    Please note that EPDM is a commercial roofing product, designed to be used in non-residential roof systems.
