ABSTRACT:
A waterproof-sheet type of roofing shingle comprises a belt-like tape attached to a bottom side of the roofing shingle facing a concrete slab. The belt-like tape has air passages for reducing a pressure of steam or vapor generated from concrete. The air passages are formed by projections or grooves and adapted to be in communication with air passages of an adjacent roofing shingle. The air passages are eventually in communication with an ambient atmosphere so as to vent the steam or vapor to the atmosphere, and therefore, bulging of waterproofing material is prevented from occurring.
