EPDM Roofing Systems
What is an EPDM Roof?
Ethyline Propolyne Diene Terpolymer (EPDM) is a dimensionally stable membrane that can withstand and resist almost any type of nature-born stress. This single-ply roof membrane, also commonly referred to as a rubber roof system, utilizes carbon black as its the molecular "backbone" which enables it to take on characteristics such as the ability to expand up to 300% yet retain 100% structural memory. EPDM also has excellent weathering resistance and serves as a superb second generation (roof-over) application.
EPDM roof systems are typically installed in one of three methods:
Mechanically attached - This application provides a lightweight, cost-effective solution whereby the roof membrane is affixed to the structural deck utilizing mechanical anchors.
Fully adhered - The system is applied by bonding the membrane directly to the affixed insulation board or other roofing membrane substrate.
Ballasted - Using large sheets and 10 to 12 pounds of rock ballast per square foot to hold the membrane in place, this roof system can be the most cost-effective due to the ease and speed of installation. However, this application does require a structural engineer's approval.
EPDM roofing systems are based on a high-performance synthetic rubber compound that provides outstanding weathering characteristics in climates worldwide. From office buildings and distribution warehouses to hospitals and schools, Firestone has an EPDM roofing solution that’s right for you.
