When it comes to protecting your property, your roof is the first line of defence. Whether you’re dealing with small leaks, ageing materials, or full-on weather damage, using the right roof repair sealant can make all the difference. At Sealant Supplies Ltd, we stock a wide range of products to support pitched roofing, flat roofing, and general waterproofing — all available with trade discounts and bulk buying options.
If you’re tackling a roofing job, either as a seasoned pro or a confident DIYer, having the right sealant on hand is key to getting a lasting, reliable finish.
Pitched Roofing: Seal and Secure
Pitched roofs are common across UK homes and offer excellent water runoff. But they still need regular maintenance, especially around joints, chimneys, and roof windows where leaks often start. We offer a great selection of roof repair sealants suitable for pitched applications.
Top picks include:
-
Everbuild Lead Mate 295ml
This lead-coloured, flexible sealant is specially designed for pointing around lead flashing. It prevents water ingress and remains permanently flexible — ideal for tricky junctions between roof tiles and leadwork. -
Bond It Bitumen Paint
A fast-drying, solvent-based coating that offers weatherproof protection for metal, concrete, and asphalt surfaces. Perfect for sealing smaller areas on pitched roofs and gutters. -
Soudal Yellow – Window, Door & Building Silicone 290ml
Though commonly used around windows, this durable, weather-resistant silicone is also great for sealing roofing gaps and edges where flexibility and adhesion are essential.
Flat Roofing: Reinforced, Resilient Protection
Flat roofs are notoriously vulnerable to water pooling, UV degradation, and long-term wear. A specialised roof repair sealant for flat roofs can extend the life of these surfaces and save you from major repairs down the line.
Best products for flat roofing include:
-
Everbuild Black Jack All Weather Roof Coating
A traditional favourite, this solvent-based coating is effective in both dry and damp conditions. It’s ideal for emergency repairs and routine maintenance. -
Acrypol+ With Fibre Waterproof Roof Coating
One of the most popular solutions on the market, this fibre-reinforced coating bridges small gaps and cracks, creating a flexible waterproof layer. It can be applied in damp conditions and offers instant protection. -
Acrypol Metal-Kote Roof Coating 20L
Designed for metal roofs, this reflective coating helps prevent corrosion and reduces solar heat absorption — great for industrial or commercial buildings.
Waterproofing: Total Coverage from the Inside Out
Waterproofing isn’t just about the outer surface — internal areas like bathrooms, wet rooms, and under-roof spaces also benefit from high-performance sealants and coatings.
Top waterproofing solutions include:
-
Cromar Cromapol Primer 20kg
A primer designed to improve adhesion before applying waterproof roof coatings. Essential for getting the most out of your topcoat. -
Cromar Roofing Emulsion 25L
A reliable bitumen-based emulsion for damp-proofing and sealing flat or pitched roofs. It’s easy to apply and provides a tough, flexible finish. -
