Features and benefits
Roofer’s No.1 Roof & Gutter Sealant is formulated specifically for sealing and weatherproofing roofing and external building components where durability and flexibility are essential. Its advanced hybrid polymer formulation adheres strongly to a wide range of common construction substrates, including metals, masonry, plastics, and coated surfaces.
Designed to withstand prolonged exposure to UV radiation, moisture, and temperature fluctuations, the sealant remains elastic over time, accommodating movement without cracking or shrinking. This makes it particularly well suited for gutter laps, sheet metal joints, roofing seams, and cladding interfaces where expansion, vibration, or thermal cycling may occur.
Supplied in convenient 300 ml cartridges, the sealant is easy to apply and suitable for both professional roofing installations and maintenance or repair work.
