A prefabricated structural system including a support frame and prefabricated panels having strength sufficient to bridge spaced support beams under the panel is disclosed. Each panel includes a sheet metal support subpanel having corrugations, a thin flat metal sheet as a top surface, and a layer of insulating foam filling the space therebetween. A Hypalon membrane is intimately and continuously bonded to the thin, flat metal sheet and has Hypalon fasteners disposed along each edge of the Hypalon sheet and connected to the Hypalon sheet by flexible flaps. The panels are disposed in a continuous array and fastener halves are joined and the corners sealed to provide a continuous Hypalon membrane unpenetrated by fastener screws above the array of panels. A flashing system is disclosed which continues the Hypalon membrane from the panel array up adjacent parapet walls and building walls and accessories extending above the roof deck and over the edge of the roof deck to the outside of underlying walls to provide a watertight roof structure. The flashing system includes plain and box fascia systems including a box gutter system, parapet flashing, all corner and end transitions for these systems, penetration flashings for vents, pipes, deck drains and curbs.
