Interlocking panels with infinitely variable relative positioning for use as siding and roofing panels. The panels are of relatively uniform thickness having raised decorative elements, such as by way of example, shake, tile, brick, stone and slate, to name a few, with a rear and side nailing flange thereon. The rear of the decorative elements include a rearward extending protrusion, with the front of the decorative elements having a continuous slot extending under the front edge of the decorative elements and effectively extending uninterrupted along the length of the panel. This allows the protrusions on the rear of the decorative elements of one course to engage the slot in the lower part of the next course in any relative position, so as to allow the breaking up of what would otherwise be a recognizable, limited pattern. The continuous slot weakens the front edge of individual panels sa that the same should not be walked on. However, by properly proportioning the projections at the rear of the panel and the slot and structure therearound, support is provided for the slot in installed panels, making it safe to walk thereon as if the slot had been formed in a discontinuous manner. Fabrication of the panel may be by various techniques, though injection molding is preferred.
