Liquid roofing involves the application of a monolithic, fully bonded, liquid based coating to a roof. The coating cures to form a rubberlike elastomeric waterproof membrane, capable of stretching and returning to its original shape without damage. Such coating systems are usually reinforced with secondary materials such as glass reinforced plastic to provide additional tensile strength. The coatings can be applied over most traditional roofing materials, including felt, asphalt, bitumen, and concrete. 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. The coating material used in the liquid roofing process is applied cold, thus negating any fire risk. Tor Elastaseal Roof Waterproofing Systems have been developed to solve the problems associated with the long term waterproofing of flat roofs, gutters and pitched roofs.
