The EPDM single ply product is a synthetic rubber roofing membrane. EPDM stands for Ethylene, Propylene, Diene Terpolomer (Monomer). The single ply EPDM rubber roof has been in use since the 1970's and offers excellent resistance to ultra-violate light rays (sun). The EPDM roof membrane can be ballasted, mechanically attached or adhered to insulation or other substrates.
EPDM Single Ply Roofing is made of similar rubber to the material used in bicycle tires providing a flexible roofing material. EPDM is available in 45 and 60 mil thickness as roofing materials. The EPDM sheets are manufactured in a variety of widths ranging from 10 to 50 feet, and lengths ranging from 50 to 250 feet long.. Seams are glued with an adhesive or taped with a self adhesive material. The EPDM can be installed as a smooth surface, or ballasted with at least 10 lbs/sf of large round river rock.
The ballast provides weight to help secure the assembly to the buildng. A 90 mil thick material is available for roofing and waterproofing installations. It is normally black in color, but is also available in white. The white EPDM membrane is used in either adhered or mechanically attached assemblies where reflectivity is desired or required.
Single ply EPDM rubber roofs provide flexibility through elongation and weather resistance in addition to waterproofing properties. Seams are glued or taped together at ends and side laps. Some systems add a sealant at side and end laps.
The large round river washed rock used on top of the material provides extra fire-resistance. These roof membrane assemblies might also used under photovoltaic and vegetative garden roof assemblies.
The EPDM roof system has to be installed to the manufacturers installation instructions, the listing, where applicable, and the building code.
