EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas.
EPDM membrane will not leech or emit hazardous chemicals. Unlike non-vulcanized elastomers that may begin curing in the field once exposed to moisture and heat, EPDM membrane has no shelf life. Its physical properties remain stable, which makes repairs much easier in the unlikely event of cuts or tears.
EPDM is available in both black and white, and is sold a broad variety of widths, ranging from 7.5 feet to fifty feet, and in two thicknesses, 45 and 60 mils.

EPDM Sizes
EPDM membrane is manufactured in various thicknesses (.045" to .090" thick) and is available as a non-reinforced or reinforced sheet (depending upon application). Other thicknesses are also available for use in non-roofing applications as a special order.
Reinforced EPDM Membranes
Reinforced membranes contain an internal fabric that is completely encapsulated within the EPDM membrane sheet and is available in various thicknesses (.045" to .075"). A fleece layer can be added to the underside of the sheet that serves as a built-in underlayment for direct re-roof applications over certain types of existing roofing material.
Vulcanized EPDM
EPDM is also manufactured as vulcanized (cured) or non-vulcanized (uncured) membrane. Vulcanized membranes have set physical properties due to the vulcanization process and exhibit consistent behavior throughout the sheet that allow the membrane to have memory. When stretched it will return to its original state. No-vulcanized EPDM will not.
Benefits of EPDM Roofing
EPDM resists thermal shock and hail damage. EPDM remains flexible and will not shatter in frigid temperatures.
EPDM is superior in its ability to withstand UV damage. EPDM offers one of the best dollar-for-dollar values.
EPDM accommodates structural movement without membrane stress. EPDM does not deteriorate.
