End lap seam construction for standing seam roof panels
First Claim
1. A generally rectangular standing seam roof panel having an upstanding seam member extending the entire length of at least one longitudinal side edge of said panel, said seam member including a longitudinally extending outer wall, a mastic waterproofing bead located on and extending the entire length of said wall at the outer side thereof, and means defining an endlap notch in said seam member at one end of said panel having a longitudinally extending notch edge located above said bead and below the top of said outer wall whereby two such panels may be disposed in overlapping end-to-end relationship with the outer side of the seam member wall of the overlapped panel nested in adjacent face-to-face relationship with the inner side of the wall of the underlapped panel in the region of said notch.

Abstract
An end lap seam construction for metal roof panels in a standing seam roof is provided wherein a continuous water-tight seal extends around the entire periphery of each panel. Mating factory installed mastic strips are employed to seal the standing side seams of adjacent panels. The end lap seam of the present invention incorporates a mastic tape which may be field-applied without any great degree of precision to mate with and bond to the side seam mastic strip of an overlapping mating panel.

5. In a standing seam roof assembly having a pair of generally rectangular prefabricated panels disposed in overlapped end-to-end relationship with each other;
- the improvement wherein each of said panels comprises an upstanding seam member including an outer wall extending the entire length of at least one longitudinal side edge of the panel, a mastic waterproofing bead located on and extending the entire length of the wall at the outer side thereof, means defining an endlap notch in the seam member of the underlying panel extending along the last mentioned seam member above the bead thereon for a distance equal to or slightly greater than the extent to which the overlying panel overlaps the underlying panel, the outer side of the wall of the overlying panel being located in adjacent face-to-face relationship with the inner side of the wall of the underlying panel below said notch.

11. In a standing seam roof assembly made up of generally rectangular prefabricated roof panels;
- the improvement wherein each of said panels comprises an upstanding seam member extending along a side edge of the panel and including a generally vertical outer wall projecting upwardly from the panel at the side edge thereof, each wall having a continuous bead of mastic sealer extending the entire length of the outer side of the wall, a first pair of said panels being located in side-by-side relationship with the seam member walls thereof in opposed face-to-face relationship to each other, a continuous strip of mastic sealer extending transversely across the top of each of said first pair of panels and up the inner sides of the walls thereof in adjacent spaced relationship to one end edge of the respective panels, a second pair of said panels respectively located with one end edge thereof in overlapping face-to-face engagement with said one end edge and the mastic strip on the respective panels of said first pair, the outer sides of the walls of the panels of said second pair being located in overlapping face-to-face engagement with the inner sides of the walls of the panels of said first pair, and a continuous elongate cap strip of generally inverted U-shaped transverse cross-section enclosing and compressed against the inner sides of the walls of all of said panels to press said walls and the mastic beads thereon laterally against each other and to compress the mastic beads on said second pair of panels against the intersecting transversely extending mastic strips on said first pair of panels.

16. In a generally rectangular standing seam roof panel of sheet metal material having an upstanding seam member integrally formed thereon and extending the entire length of at least one longitudinal side edge of said panel;
- the improvement wherein said seam member includes a main portion extending longitudinally along said side edge from one end edge of said panel to a lap location spaced longitudinally from the opposite end edge of said panel, a lap portion of said seam member extending from said main portion at said lap location to said opposite end edge of said panel, said main portion of said seam member being of a generally inverted U-shaped transverse cross-section and including a generally vertical outer wall projecting upwardly from said panel to define one leg of said U-shaped section, an inner web defining the other leg of said U-shaped section and spaced inwardly of said panel from said outer wall, the outer wall of said main portion of said seam member extending from said main portion beyond said lap location to define said lap portion of said seam member.
