What is EPDM?

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. Trims are available in both black and white. EPDM will be installed with water based glue or self adhesive, with the seams of the roofing system sealed with specially formulated tape.
