HSS Roof Repair Tape — Waterproof Commercial Roofing & RV Sealant Tape, Grey 2in x 25ft, UV- and Weatherproof

HSS Hanse Syntec Systems Sealant Tape with MicroSealant is a commercial-grade, instantly waterproof roofing tape that seals leaks on roofs and RVs and resists UV and weather damage.

This high-performance roof repair tape combines a durable backing with a patented MicroSealant layer to create a fast, long-lasting seal. Engineered in the USA for commercial use, the tape is designed to bond to a wide range of roofing materials and surfaces, stopping leaks immediately and staying flexible through temperature swings. Its grey finish blends with most roof colors while offering heavy-duty protection against sun, rain, and snow.

How does the MicroSealant technology stop leaks right away?

The MicroSealant is a pressure-activated adhesive that forms a watertight bond on contact, filling small gaps and conforming to irregular surfaces. It starts sealing instantly and continues to cure to deliver durable adhesion under moving joints or thermal expansion.

• Patented micro-particle adhesive for quick tack and long-term grip
• Conforms to seams, cracks, and textured roof surfaces
• Creates an immediate waterproof barrier on application

Will this tape hold up to sun, rain, and freezing temperatures?

Yes — the formulation is made for exceptional UV and weather resistance so it won’t crack, peel, or lose adhesion under intense sun or repeated freeze-thaw cycles. The tape remains flexible and bonded even after months of exposure, protecting repairs through seasonal extremes.

• UV-stabilized backing prevents breakdown and discoloration
• Flexible construction resists splitting in cold weather
• Waterproof barrier resists prolonged moisture and runoff

Which surfaces and applications is this roofing tape suitable for?

The HSS sealant tape adheres to most common roofing materials and is particularly useful for RV roofs, flat commercial roofs, flashing, gutters, vents, and patched seams. It’s ideal for quick emergency repairs and for planned maintenance when a durable, weatherproof patch is needed.

• Bonds to metal, EPDM, TPO, PVC, asphalt, and many coated surfaces
• Works on horizontal and slightly angled surfaces including RV domes
• Useful for flashing, vent collars, seams, seams on trailers and skylights

How do I apply the tape for best performance?

Surface preparation and correct application ensure the longest life. Clean the area of dirt, loose material, and moisture, then press the tape firmly with a roller or hand pressure to activate the MicroSealant layer. Overlap seams and smooth out any air pockets for a continuous seal.

• Clean and dry surface; remove loose debris and oil
• Cut to length, peel backing, align, and press firmly into place
• Overlap existing tape by at least 2 inches for seam repairs
