Roof Refurbishment

Refurbishment or replacement of defective or problematic roof coverings is a common problem. Stripping off the existing roof covering and replacing it is can be an expensive proposition and a logistical nightmare. Liquid roofing involves the application of a monolithic, liquid polyurethane coating to a roof. The coating cures to form a rubber-like elastomeric waterproof membrane, which is fully bonded to the existing roof covering and capable of stretching in order to accommodate movement in the roof. The coatings can be applied over most traditional roofing materials, including felt, asphalt, bitumen, and concrete


  • Cost Effective

Liquid roofing systems are a reliable, cost effective, long term solution to failed roofs. And because liquid systems can be applied directly over the existing materials, costly removal and disposal to landfill is avoided. This allows the resurfacing of the defective roof to take place with minimum disruption to the occupants of the building.

  • Safety

Unlike the installation processes of felt, asphalt and bitumen membranes, liquid roofing does not involve hot works. Hot work on roofs is an extremely high-risk process, that poses a significant fire risk to contractors as well as the building and its occupants.  Liquid polyurethane roofing systems require no hot works, removing any fire risk from the project.

When applied, liquid roofing systems encapsulate the surface they are applied to, preserving whatever is underneath and protecting it from weathering. This is especially desirable when dealing with asbestos roofs, as attempted removal of asbestos roofing can damage it, releasing material that can trigger asbestosis. Using a liquid coating system instead seals the asbestos, therefore making disturbance of the material more difficult.

  • Ease of Detailing

Pipe penetrations, roof lights, upstands and other complex detailing are easily incorporated into the waterproof seal, becoming an integral part of the roof membrane without the need for any additional mechanical or adhesive fixings.
