Failing Seams on an EPDM Rubber Roof
Black rubber vs white rubber? The condensed argument goes like this: Black rubber (bad) is glued together and the glue will eventually fail. White rubber (good) is heat-welded together and becomes a single, impermeable membrane. Black rubber is called EPDM (ethylene propylene diene monomer). It is essentially the same thing as a rubber tire inner tube rubber for inside a car tire. White rubber is in two types; either PVC (polyvinyl chloride) or TPO (thermoplastic polyolefin).
They are both heat-welded together and they are both better than EPDM. However, we at Ace Roofing believe that the best product that we can offer our customers for flat roof applications is a PVC membrane manufactured by IB Roof Systems. These roofs will last 30+ years and we take pride in installing them with integrity. Click on this link FLAT ROOFS for more information.
