Liquid Roofing is the process of waterproofing a roof by the application of a specialist liquid roof coating. It is suited to all types of roof including flat, pitched and domed. It very popular on commercial roofs. Liquid application systems provide one of the most cost effective methods for making a new or existing roof waterproof. Liquid systems can provide savings of up to 70% on roof replacement costs. Single component moisture-cured polyurethane coatings are the majority of today’s liquid applied roof coating technologies.
Liquid roofing involves the application of a monolithic, fully bonded, liquid based coating to a roof. The coating cures to form a rubber-like 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. Liquid roofing is applied cold.
Liquid roofing is sometimes the preferred method to make an old roof “cool” as a number of finishes have reflective solar properties. It is most commonly used to extend the life of a TPO roof that is near the end of its lifespan.
