US 5,697,197 A · Roof panel system having increased resistance to wind loads

Abstract

A standing seam roof assembly in which adjacent roof panels are supported by underlying support structure in overlapping edge relationship to form a standing seam between adjacent roof panels is disclosed. A plurality of fasteners secures medial portions of the roof panels to underlying support structure so that the standing seam is prevented from unfurling during uplift of the roof panels. The fasteners rigidly attach the roof panels to the underlying support structure, or alternatively, secure adjacent roof panels relative to one another. Additionally, the use of a floating underlying structure allows the panels to expand and contract as a result of environmental conditions without damaging the panels or underlying structural connections. The fasteners may be located adjacent to structural corrugation crowns located in the medial portions of the panels as well as adjacent to the standing seam.

Dependent claims

A standing seam roof assembly in which adjacent roof panels are supported by an underlying support structure in overlapping edge relationship to form a standing seam between adjacent roof panels, the standing seam roof assembly comprising:

a first roof panel having a female sidelap portion and a corrugated medial portion forming a first clip retaining surface;
a second roof panel having a male sidelap portion and a corrugated medial portion forming a second clip retaining surface, the female sidelap portion and the male sidelap portion of the first roof panel and the second roof panel, respectively, interconnecting to form the standing seam;
and
clip means for securing the medial portions of the first and second roof panels so that the standing seam is prevented from unfurling during uplift forces on the first and second roof panels, the clip means including first and second radiused portions each having distal ends, the distal ends contacting the first and second clip retaining surfaces.

1 more element

A standing seam roof assembly having increased resistance to unfurling as a result of wind loads upon the roof assembly, comprising:

a pair of adjacent roof panels having sidelaps and corrugated medial portions, the medial portions including hook engaging surfaces, the sidelaps interconnected to form a standing seam;
and
panel retaining means for retaining the panels, the panel retaining means including a pair of hook clips, the hook clips engaging the hook engaging surfaces of the medial portions of the roof panels to secure the roof panels and prevent unfurling of the standing seam as a result of wind loads upon the roof panels.
