Abstract
Method and apparatus for a metal roofing system having a plurality of panels having overlapping edges forming a ridge wherein the ridge is covered by a snap-on cap wherein the cap has opposing legs which are resiliently biased toward each other and are shaped to precisely conform with the shape of the lower portion of the ridge so that the cap can be firmly and securely attached to the ridge. A plurality of screws are inserted through the apex of the ridge so as to attach the roofing panels to the roof of the building structure. An end cap is also provided as a sealing mechanism for the open ends of the ridges and ribs disposed between the ridges.
Claims16
A roofing system for attachment to a framework of a building, comprising:
- (a) a plurality of panels, said panels having left and right edges, wherein said left and right edges are sized and shaped to mate to each other;
- (b) wherein said right edge has a raised portion consisting of a downwardly extending lower right leg and a lower right foot which terminates as a free end, and said left edge has a raised portion consisting of a downwardly extending lower left leg and a lower left foot which terminates as a free end;
- (c) wherein said panels overlap on said left and right edges to form a hollow ridge, a first ridge being disposed on said left edge and a second ridge being disposed on said right edge, each said ridge being wider at the top than at the bottom and having a concave surface proximate said bottom;
- (d) a plurality of upstanding ribs disposed in a spaced apart relationship in the non-overlapping flat portion of the panels between said first and second ridges, each said rib being wider at the top than at the bottom and having a concave surface proximate to said bottom;
- (e) a plurality of caps disposed on each said ridge to prevent leakage of water through said panel;
- and
- (f) each said cap having a top, a left leg and a right leg, wherein each leg has an inset on a distal end being inset toward said opposite leg, wherein said inset is convex shaped and mated to said concave surface on said ridges and wherein insets are resiliently biased toward each other so that said caps are removably secured to said ridges to provide a water-proof seal.
A method for roofing, the resulting roof for attachment to a framework of a building, comprising the steps of:
- (a) providing a plurality of panels, the panels having left and right edges, wherein the left and right edges are sized and shaped to mate each other,
- wherein said right edge has a raised portion consisting of a downwardly extending lower right leg and a lower right foot which terminates as a free end, and said left edge has a raised portion consisting of a downwardly extending lower left leg and a lower left foot which terminates as a free end,
- and wherein a plurality of upstanding ribs are disposed in a spaced apart relationship in the non-overlapping flat portion of the panels between said first and second ridges, each said rib being wider at the top than at the bottom and having a concave surface proximate to said bottom;
- (b) forming a hollow ridge by overlapping the panels on the left and right edges, a first ridge being disposed on the left edge and a second ridge being disposed on the right edge, each ridge being wider the top than at the bottom and having a concave surface proximate the bottom;
- (d) disposing a cap on each ridge to prevent leakage of water through the panel;
- and
- (d) wherein each cap has a top, a left leg and a right leg, wherein each leg has an inset on a distal end being inset toward the opposite leg, wherein the inset is convex shaped to mate to the concave surface on the ridges, and wherein the insets are resiliently biased toward each other so that the caps are removably secured to the ridges to provide a waterproof seal.
