Liquid Applied Flat Roof

Useful for upgrading an existing felt or asphalt roof

Liquid applied roofs are a resin material applied cold to a glass fibre matting. The resin is laid in two coats and can be finished a light grey. Wood rolls can also be formed on the roof so that the finished surface looks like a lead roof. (But if yours is a listed building or in a conservation area, you may still be required to replace an existing lead roof with lead.) The resin can be formed around features such as vents, ducts and pipes which often protrude through roofs.  The material can be used to upgrade an existing felt or asphalt roof,  by adding insulation over the existing roof and then applying the resin. The old roofing acts as a vapour barrier.

This type of roof should be laid by accredited installers and they should provide a 25 year warranty. To extend the warranty a further 25 years, the roof can be recoated with the material.
