ETHYLENE PROPYLENE DIENE MONOMER (EPDM)
EPDM is a synthetic rubber made from Ethylene Propylene Diene Monomer (EPDM) Polymer. It is a versatile membrane that offers a variety of installation options including fully adhered, ballasted, or mechanically attached that deliver long-term weatherability and exhibit exceptional wind uplift resistance. It has a high resistance to damage from heat, cold, and UV rays, but the EPDM membrane shrinks with age, especially at walls and curbs.
The drawback to EPDM roofs is the glued and/or taped seams, which are common causes of leaks. Also, black EPDM roofs are not considered "green" roofs and therefore do not offer heat reflectivity or emissivity and do not qualify for potential energy savings and rebates. Depending on the thickness of the EPDM membrane, insulation layers, deck type, and installation method, EPDM warranties range from 10 years to 30 years.
