Abstract: The present invention is directed to methods of interlocking panels as well as panels and paneling kits useful in working those methods. The complete interlocked panel assembly resulting from working these methods exhibits a horizontal pattern, excellent wind uplift resistance and water tightness. Concealed fastening devices for panel-to-substrate affixation add to the water proofing and aesthetic qualities of the finished panel assemblies of the present invention. The self-interlocking panels of the present invention are easy to install, especially in that no external clips or other fasteners are necessary for panel-to-panel affixation. The interlocking panels of the present invention may be installed from the top of the underlying structure downward.

Abstract: A roofing structure includes a series of overlapping, interlocking panels, each of which has a small ridge and a large ridge at opposing edges of the panel. The large ridge of each panel overlaps a small ridge on an adjoining panel, but the ridges are sized and spaced from one another to interrupt capillary movement of water between them. Each panel is fastened to a roof board using a noninvasive fastener which fits within a groove in the upper surface of each panel. The fastener can slide relative to the groove to allow expansion and contraction of the panel without buckling or breaking.
