A panel composed of wood sawn tapered shingles including an undercourse of longer shingles and an upper course of shorter shingles disposed with the tips of the shingles in the two courses even and the shingles of the two courses being integrated by staples penetrating both courses of shingles and extending into a narrow cleat behind the undercourse of shingles. The lower edge of the cleat is spaced from the butts of the shingles of the undercourse for engagement with the tips of the shingles of the next lower panel to serve as a gauge for establishing the relative positions of adjacent upper and lower panels applied to a roof or sidewall.
