Roof‑Mate Roof & Gutter Sealant is a polymer-enhanced, lap‑jointing sealant designed specifically to prevent leaks in gutters, downpipes, roofing penetrations, and flashing. Its robust, yet flexible formulation ensures it can accommodate typical building movements—up to around 5%—without cracking, and remains reliably pliable for about 15 years . The sealant provides strong adhesion to a wide range of building materials, including metal, plastics like PVC, painted surfaces, stone, timber, brick, bitumen, and asphalt.One of its standout features is its ability to be applied even in wet conditions, making it practical for urgent repairs during rain or damp weather .
Offered in a 310 ml cartridge (with bulk options of 4, 12, or 25 cartridges depending on supplier), it dispenses easily using a standard sealant gun and cures to form a durable, weather-resistant seal. The black finish helps it blend into most roofing and guttering systems, giving a professional appearance once applied.
Perfect for both emergency patches and longer-term maintenance work, Roof‑Mate is a go-to solution for builders, roofers, and DIYers seeking a reliable fix for leaks and joint issues in roofing and drainage systems.
