Is Your Timber Flat Roof Failing?
Timber and OSB flat roofs commonly suffer from:
• Failed felt systems
• Movement at board joints
• Ponding water
• Delamination
• Moisture ingress and timber rot
• Leaks around roof lights and trims
Our liquid PU system eliminates lap joints and forms a continuous waterproof membrane directly bonded to the timber substrate.
