ABSTRACT:
A roofing shingle having apertures formed therein in upwardly spaced relation from the lower or free edges of the tab or tabs thereof adapted to receive the lower corners of the tabs of the shingles in the next higher course of shingles, when said shingles are applied in courses, in order to anchor said tabs to reduce any likelihood of damage commonly resulting when free, unanchored shingle tabs are peeled away from the roof by high winds. The apertures may permit the passage of some rain or other moisture therethrough, but any such moisture is trapped and safely disposed of by a special backing applied to the shingle, the backing also serving as a "dry-ply" between the shingles and the sheathing boards of the roof.
