Get your flat roof ready for bad weather with Thompsons 10 Year Roof Seal - it seals up any damaged or worn areas, repels water molecules and adds an extra binding strength to the surface. As a result, it's commonly used on felt roofs for sheds, but will also work on asphalt, slate, tiles, concrete, brick and corrugated metal. It helps to keep the inside of your shed well insulated and free from drips or leaks.
The roof seal has excellent UV resistance, meaning the deep black colour won't fade in the sun. After six hours, when the first layer has fully dried, a second coat can be applied, which provides extra protection from the rain.
Thompsons Roof Seal has a malleable formula that moves with the roof, so it prevents cracks from appearing and stops the surface from flaking in the heat or cold.
• Repairs your flat roof to get it weatherproof
• Suitable for use with felt, asphalt, slate, tiles, concrete, brick and corrugated metal
• Outperforms standard bitumen paint
• Flexes with the natural movement of the roof
• Resists the sun's UV rays, so colour won't fade
• Rainproof in six hours
• Coverage of approximately 0.5m² per litre
