- Roof leaks
- Gutter leaks
- Pipe and flashing patches
A fast, clean alternative to asphalt cement for leaks on smooth surfaces: gutters, metal, rubber, PVC, and flashings. Not for shingle roofs, and you get one shot at placement.
Pros
- Instant waterproof bond with no cure time; press it on and the patch is done
- Thick butyl conforms over gutter seams, flashings, pipes, and RV/metal roofs cleanly
- Extreme -70 to 200 F service range and works applied wet, cold, or even underwater
Cons
- Cannot be repositioned; once it touches the surface the bond is permanent
- Not made for asphalt shingles, so it is the wrong tool for a typical composition roof leak
- Needs a reasonably smooth, clean surface; it will not conform well over granular shingle texture
