Repair Mastic & Waterproofing

Roof repair mastic is designed to heal cracks and splits in flat roofs and we stock waterproof mastic from leading brands including Cromar and Black Jack. This type of mastic creates watertight repairs, perfect for emergency situations and remedial work.

Black Jack’s 903 Bitumen Trowel Mastic is competitively priced and is ideal for waterproofing, bonding and sealing. It adheres to most construction materials, including roofing felt, cast iron, fibre cement and slate. 

Alongside our mastic waterproofing options, we also stock roofing and guttering waterproofing compounds as well as all-weather compounds and roof coating. If you’re unsure which is the best option for your project, give our friendly team a call on 01752 692 221.
