Abstract: A system for constructing a roof on a roof support structure comprising (a) identifying and mapping the roof by zones of demand requirements throughout the area to be covered by the roof; (b) covering the area with metal panels; (c) choosing a connecting process for connecting side-adjacent and end-adjacent panels, wherein a connecting process is selected for each demand zone to inter-connect the side-adjacent and end-adjacent panels that satisfies the performance requirements of that particular demand zone so that all of the metal panels are inter-connected to each other and to the roof support structure.

Abstract: A zone based roofing system for roofing a building, the roof of the building identified by demand zones of the roof, the type of seaming process used for each demand zone varied to connect the standing seams of the panels to meet the minimum requirements of the demand zones. The panels are secured to the roof support structure and adjacently disposed panels are interlocked such as by seaming according to demand zone requirements to achieve demand quality for each zone and thereby minimizing the cost of the roof.

Abstract: A module gauge is described for moduling the next-to-be-erected roof panel to conform its actual width with the design modular width by compressing or expanding the roof panel as needed. Conformation of the panel widths results in a weathertight roof structure.

Abstract: 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.
