Abstract:
1. A method of producing a seamless roofing system comprising the steps of: providing a plurality of hardened foam roofing panels, applying layer of a rising foam adhesive to a pre-determined surface of a roof to be covered, placing a first hardened foam roofing panel of said plurality of hardened foam roofing panel upon said rising foam adhesive upon said roof to be covered; each said hardened foam roofing panel being formed of polyurethane foam wherein each said hardened foam roofing panel has a density of about 2.5 to 3.16 cubic pounds per foot and said hardened foam roofing panel has a top surface, a bottom surface, and at least one first indented periphery; said top surface having an integral layer of fabric bonded to said hardened foam roofing panel; mating said at least one first indented periphery of said first hardened foam roofing panel to a further hardened foam roofing panel upon said layer of rising foam adhesive applied to said predetermined surface of said roof, said further hardened foam roofing panel having at least one further indented periphery, said at least one further hardened foam roofing panel having a density substantially equal to said density of said first hardened foam roofing panel, said at least one first indented periphery of said first hardened foam roofing panel being larger than said at least one second indented periphery of said second hardened foam roofing panel, thereby preventing a tight fit between said at least one first indented periphery of said first hardened foam roofing panel and said at least one second indented periphery of said second hardened foam roofing panel, fitting said at least one first indented periphery and said at least one second indented periphery loosely together with a gap provided between said first hardened foam roofing panel and said at least one second hardened foam roofing panel, and, allowing said rising foam adhesive to rise within said gap therebetween.
