Generally rectangular wood shake covering elements laid up in overlapping courses are spaced apart transversely of their lengths by sawn wood shingle filler elements. Preferably the major portion of the overlapped portion of each course is formed by the tips of the sawn shingle filler elements, whereas the major portion of the exposed portion of each course is formed by the wood shake covering elements. One of such elements can be notched providing a transversely extending shoulder dividing such element into tip and butt portions of unequal width. In application, the shoulder tightly abuts the adjacent element. The covering and filler elements can be used to construct a roofing panel which includes a sawn shingle underlayer beneath each course and waterproof paper which underlies at least the major portion of the shingle underlayer but which is secured to the roofing panel by having one end portion interposed between the underlayer and the covering or filler element at one end of the panel. The covering elements can have registered kerf lines to align the successive courses of panels.
