Structall Building Supply - The Professional Contractor's Resource for Aluminum Building Supplies & Laminated Panels

For use on virtually all roofs, RoofSeal / OneStep Tape incorporates Eternabond’s advance MicroSealant Technology and features a UV stable backing.
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.
RoofSeal / OneStep permanently bonds to materials such as EPDM, TPO, most PVC, CSPE/Hypalon, CPE, SBS, APP modifies, asphalt BURs, coal tar BURs, all metal roofs, tiles, shingle, aluminum, Galvanized steel, gypsum board, wood, polyethylene, propylene, polystytrene, fiberglass, brick, concrete, masonry, OSB, etc.

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.

Surface Preparation
Surface must be clean and dry; free of loose rust and scale, dust, talc, and dirt. Oil, grease, and other contaminants should be removed with a suitable solvent / cleaner.

The Year After Year, All-Season Solution for Preventing Leaks

Leaks occur for two main reasons: water finds air tunnels, or the sealant bond breaks down. Structall offers Flex-Seal, a sealant tape which combines two superior products into one.

Both products working together create an extremely flexible and durable sealant solution for panel, extrusion, skylight, and window sealing applications, creating a sealing tape that has no air tunnels and a bond that won’t break.

Flex-Seal bonds instantly and protects immediately, no wait time is necessary. A full bond is achieved in just 24 hours.
Superior resistance to UV, chemicals, mildew, dirt & environmental extremes.
Remains flexible even under very cold conditions (-60˚ F).
It remains stable even at temperatures as high as 270˚.
Application of Flex-Seal is clean and simple, no messy solvents to deal with.
No additives or plasticizes that can create dirt problems.
The surface is essentially “self-cleaning”. Typical airborne dirt washes off with each rain.
The peel strength is 17 lbs. per linear inch, compared to other tapes that fall somewhere between 4 pli, and 8 pli.
