Abstract
A roof or wall covering comprising a plurality of horizontal courses of molded plastic panels each formed with a single row of simulated shake shingles. The panels have a continuous upper interlock flange that facilitates inner-engagement of the panels of overlying courses without cumbersome handling of numerous small interlock fingers which can be missed during installation. Cooperating detents are provided between the overlying lower and upper marginal edge regions which facilitate proper positioning of the panels and which support the weight of the panel during securement to a wall surface. A bottom interlock flange is supported transversely across a rear side of the panel by vertically-spaced support plates which facilitate both liquid drainage and air circulation through the installed wall covering. In the preferred embodiment, the panels in alternate courses are identically formed with different shake patterns for enhancing the natural appearance of the wall covering.
