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.
