RoofSeal/OneStep tape is used to seal roof joints (seams) and tears, flashings, copings, skylights, gutters, etc. Perfect for repairing and restoring roofs on mobile homes and RVs. RoofSeal/OneStep seals to itself so it can be cut and folded around an object.

For use on virtually all roofs, RoofSeal/OneStep features a UV stable backing. With the exception of surface prep, RoofSeal/ OneStep is a one-step permanent repair system for virtually all roof types, and roof accessories. RoofSeal/ OneStep creates a waterproof, moisture, and air tight barrier with no additional sealing required. RoofSeal/ OneStep remains flexible to temperatures as low as -57C making it virtually impossible to thermally shock the seam causing a leak.

RoofSeal/OneStep bonds to a wide range of surfaces including difficult roof materials such as: EPDM, TPO, aged PVC, CSPE/Hypalon, CPE , SBS, APP modifieds, asphalt BURs, coal tar BURs, all metal roofs, tiles, shingle, aluminum, Galvanized steel, gypsum board, wood, polyethylene, propylene, polystyrene, fiberglass, brick, concrete, masonry, OSB, etc.
