A synthetic foam roofing system having roofing sections with a relatively broad undersurface and exposed surface configured to resemble interlocked and overlapping roofing shingles. Ridge, valley, hip, starter gable and starter course shingles are all constructed in a manner similar to the roofing sections to interface and interlock with the roofing sections. The roofing sections and interfacing components may be affixed by conventional means such as nails and adhesives to roof boards, rafters or over old existing roofing structures utilizing wood batting.

A method of molding a composite foam synthetic resin product in an open cavity mold comprising: providing an open cavity mold having a step along a first end and first side of said mold cavity; applying a barrier coat to the inside surface of said mold cavity; providing a pressure plate cover having a stepped portion along one side and one end said stepped portion adapted to engage a second side and end of said mold cavity; detachably securing a base member to said pressure plate with a side and end of said base member abutting the stepped portion of said pressure plate; chilling the mold in a chilling compartment to chill the surfaces of the mold cavity; injecting a foamable thermosetting resin reaction mixture into the chilled mold cavity; securing the pressure plate and attached base member into said mold with said base member lying on the stepped portion along the first side and end of said mold cavity; curing the resin reaction mixture for a period of time sufficient to permit it to foam and adhere to said base member; removing said pressure plate from said mold after completion of curing; and detecting the composite foam synthetic resin product from said pressure plate whereby a portion of the base member along one side and one end is exposed and a portion of the foamed resin reaction mixture is exposed along the opposite side and end of said product.
