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.

1. A monolithic roofing surface membrane formed in place on and in combination with a roof, said roofing surface membrane comprising:a sprayed-on seamless first layer of a spontaneously curable polymer, said polymer having a lower surface integral with the roof, a second layer of a mesh placed on said first layer of polymer during curing, said mesh including a plurality of fibers separated by recesses, wherein upon curing said cured polymer extends through said recesses in said mesh and surrounds said fibers of said mesh, and, said first and second layers being covered by a waterproof and ultraviolet resistant coating.
