EPDM Roofs

The EPDM (ethylene propylene diene monomer) rubber roofing membrane has been an appealing choice of the low-slope roofing industry for over 40 years, with more than 500,000 warranted roof installations on 20 billion-plus square feet. Annually, EPDM accounts for over 1 billion square feet of new roof coverings in the United States.

EPDM also has one of 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 wind resistance

What is EPDM?

EPDM is an elastomeric compound that is manufactured from ethylene, propylene, and a small amount of diene monomer. These ingredients are synthesized to produce a product that exhibits a high degree of ozone, ultraviolet, weathering and abrasion resistance, and outstanding low temperature flexibility. These ingredients also contribute to resistance to acids, alkalis, and oxygenated solvents (i.e., ketones, esters, and alcohols).
