Abstract:
1. A roofing system comprising: a) a plurality of support members secured to a roof deck, a plurality of said support members spaced apart from one another, a plurality of said support members having a generally flat support flange spaced above said roof deck; b) a plurality of insulation blocks positioned between a plurality of said support members, a plurality of said insulation blocks having a thickness such that a top surface of said insulation block has a same height or a less height than a top surface of a plurality of said support flanges when said support members and insulation blocks are installed on said roof deck; c) a plurality of roof panels, each of said roof panels includes a peripheral edge, said roof panels positioned over a plurality of said insulation blocks, a plurality of said roof panels substantially not bonded to a plurality of said insulation blocks, a plurality of peripheral edges of adjacently positioned roof panels overlapping one another; d) a sealant positioned between a plurality of said overlapping peripheral edges of said roofing panels, said sealant forming a watertight seal between said overlapping peripheral edges; e) a plurality of compression bars designed to compress together said overlapping peripheral edges of said roofing panels, at least two of said compression bars positioned at least partially on top of said overlapping peripheral edges of said roofing panels, at least two of said compression bars including a plurality of openings along a longitudinal length of said compression bars, each of said at least two of said compression bars including a body and only one lip along at least a portion of a longitudinal length of said body of said compression bars, said body prior to being secured to said roofing panels having two sides and a generally flat and planar bottom surface lying in a bottom plane, said lip prior to being secured to said roofing panels angling downwardly from one of said sides of said body of said compression bars such that a front end of said lip is positioned below said bottom plane of said body, said other side of said body prior to being secured to said roofing panels absent any lip, a plurality of said compression bars secured to said roofing panels such that said flat and planar bottom surface of said body is positioned over at least one of said roofing panels and lies flat on at least one of said roof panels and said lip is positioned over at least one edge of said roofing panel; and, f) a plurality of connectors, said connectors include a top and body portion, said body portion of said connectors penetrating through one of said openings in said body of said compression bar and through said overlapping peripheral edges of said roofing panels and through said sealant between said overlapping peripheral edges and through said through said support flange of said support member, said plurality of said connectors causing a plurality of said compression bars to apply a substantially even compression force on said overlapping peripheral edges of said roofing panels and to said sealant positioned between said overlapping peripheral edges of said roofing panels.
