Is there a warranty on EPDM? Yes, black EPDM carries a 20 year warranty against weatherability and factory defects. Warranty excludes chalking. Can EPDM be bonded directly over asphalt, tar, shingles, asphalt rolled roofing or felt paper? No, the oils in pertroleum based products will cause EPDM to swell and fail. EPDM should be bonded over 5/8″ plywood, 5/8″ OSB board, or polyisocyanurate board with a fiberglass backing. Can I install EPDM membrane directly over an existing roof? You can install EPDM membrane over an existing roof only if a new layer of 5/8″ plywood, 5/8″ OSB board or polyisocyanurate board with a fiberglass backing is used as a barrier to protect the EPDM.
