EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States, Canada and worldwide. Its two primary ingredients, ethylene, and propylene are derived from oil and natural gas.
EPDM is available in both black and white colors and is sold a broad variety of widths and length, ranging from 10×100, 20×100, 30×100 feet to 50×100 feet, and in three thicknesses, 45,60 and 90 mils (most required is 60 mil).
EPDM 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 Ballasted Systems, the workhorse of the three EPDM roofing systems, account for approximately 35 percent of EPDM installations today. Using large panels measuring up to 50 feet by 100 feet, the ballasted system provides fast coverage at a relatively low cost.
The EPDM panels are loose-laid over the insulation and held in place by smooth, river-washed stoned or concrete pavers. Ballasted systems are primarily used for large new construction projects but can also be used on roof replacement or recovery projects where the existing structure can support the additional weight.
Ballasted systems are traditionally the easiest of all systems to install and have earned the Underwriters Laboratories Class A rating.
