Abstract:
A rigid roof panel system that includes a plurality of overlapping, underlapping and interlocking, application specific panels installed on roof structures using trusses or rafters having a minimum roof pitch of 3:12 wherein each panel is affixed directly to a top edge of said truss or rafter with no conventional plywood or other rigid sheathing and no moisture barrier required and employs a series of horizontally, vertically and diagonally arrayed water channels that perform their function of shedding water beneath the exposed or visible top surface of the overlapping panels while also providing a method of positively positioning each panel with adjacent panels of the same course and adjacent panels of the previous and following courses with said panels employing an integral seal along a horizontal head-lap and a diagonal edge-lap for each overlapping and underlapping seam, and each panel being securely fastened to the trusses or rafters of the roof structure by means of self sealing, threaded fasteners that are tightened to compress the integral seals and are covered by a composite plug whose design features an exposed surface identical in texture and color to the panel in which it has been installed, whereby said panels are injection molded with a thermoplastic compound comprised in part of recycled plastics, tire rubber and printed circuit board resin wherein said thermoplastic resins, additives and rubber unite in a homogenous blend hardening around and binding to the integral printed circuit board resin, and in which a fiberglass mesh sheet is encapsulated in said compound during the injection molding process providing structural rigidity and the ability to withstand the intermittent flame and fire brand tests required to achieve a UL Class A fire rating as well as wind uplift tests as specified by UL
