Fluid Applied Roof Membrane speaks to what is fluid applied roof membrane.
They are used primarily for domes, shells and other complex shapes that are difficult to roof by conventional means. Such shapes are often too flat on top for shingles, but too steep on the sides for built up roof membranes and if doubly curved they are difficult to cover with preformed sheets.
Fluid membranes are installed in liquid form with a roller or spray gun usually in several coats and cure to form a rubbery membrane. Materials applied by this method include neoprene, with a protective layer od CSPE, silicone, polyurethane, butyl rubber and asphalt emulsion.
Fluid membranes are also used as a waterproofing layer over sprayed on polyurethane foam insulation in proprietary roofing systems designed for surfaces that are hard to fit with flat sheets of insulation and membrane. These systems are also a convenient means for adding thermal insulation and a new roof membrane over existing deteriorated built up roofs on any shape of building.
Membranes for low slope roofing can have life expectancies ranging from 10 to 30 years, depending on the membrane material and thickness, the geographic location of the roof, its exposure to extremes of temperature and UV radiation, and the quality of the roof’s installation and maintenance.
