RoofSeal/OneStep creates a waterproof, moisture and air tight barrier with no additional sealing required. RoofSeal/OneStep remains flexible to temperatures as low as -70°F making it virtually impossible to thermally shock the roof causing a leak.

Basic Use

Eternabond RoofSeal/OneStep Tape is used to seal roof joints (seams) and tears, flashings, copings, skylights, gutters, etc.  Perfect for repairing and restoring roofs on mobil homes and RVs.  Very flexible, RoofSeal/OneStep seals to itself so it can be cut and folded around an object, as if wrapping a present.
