Your roof material may actually be Alpha Superflex TPO instead of EPDM. These are both considered rubber roof materials, and both can use the Dicor sealant. The way to tell if you must know the type, is to remove the inside bezel from a ceiling vent and look at the roof material that is folded down from the roof. If it is white with black underneath, then it is EPDM, but if it is all white it is TPO.
