Abstract
A uniformly applied monolithic roofing surface membrane at appropriate thickness and pitch is field applied upon a surface. The surface membrane may be field applied from a spray applicator foam dispenser moving between two parallel tracks. The uniform application of foam at each pass is assured, by accelerating the speed of the foam dispenser at the end of each pass, by providing continuous movement of the spray applicator upon the tracks. The monolithic roofing surface monolithic thus formed includes a spontaneously curable polymer, such as low rise polyurethane adhesive or polyurethane foam, having a mesh such as of fabric or fiberglass therein, with a silicone coating thereon.
