EPDM is an extremely durable synthetic rubber membrane (ethylene propylene diene terpolymer) widely used in low slope building in the United States. The two main ingredients are ethylene and propylene which are derived from oil and natural gas.
EDPM roofing holds several advantages over traditional asphalt shingles:
EPDM can be installed directly over plywood board, making roof installation relatively quick and cost-effective. Asphalt, tar, felt, or shingle roofing must be removed prior to the application of EPDM – the petroleum content in these roofing materials can cause the rubber roofing to swell, rendering the roof unstable.
The downside to using the rubber material comes only in a very few circumstances. Climates that are consistently humid or extremely wet may not be the ideal site for an EPDM flat roof. Dry conditions are required for proper installation of the rubber adhesive as well.
Faulty installation can cause bubbling, blistering, and tearing of the EPDM. Hire a professional like SUNNY ROOFING, experienced in flat roofing installation to avoid these problems.
