Flat & Low Slope Roofing

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, 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, 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.

Superior Performance
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

EPDM's high resistance to wind damage has also proven to be an increasingly desirable attribute. These roof systems can be designed to meet a variety of wind uplift criteria from Factory Mutual, including 1-60, 1-90, and 1-120 ratings and greater, and the stringent code of Dade County, Florida.  Architects, roof consultants and contractors have come to depend on EPDM's time tested, long-term performance.
