Gorilla Waterproof Patch & Seal Tape – Flexible Leak Repair for Roofing, Gutters & More

Gorilla Waterproof Patch & Seal Tape is the ultimate repair solution for anyone dealing with outdoor leaks, tears, or gaps. Designed with a thick, rubberised backing and ultra-strong adhesive, it conforms to uneven surfaces and forms a long-lasting seal—even underwater‡.

This tape is trusted by tradespeople for roofing and gutter repairs, and by campers and caravan owners for sealing trailers, tents, and RV panels. It’s wide enough to cover large cracks, flexible enough to wrap around pipes, and strong enough to hold up in extreme weather.

Use it to patch holes in tarpaulin, seal gaps around window frames, reinforce drainage pipes, or extend the life of inflatable pools. It’s a must-have for toolboxes, glove compartments, and emergency kits—ready to stop leaks before they become costly problems.
