Abstract

An asphalt shingle having an asphalt-coated substrate sheet with a top surface and a bottom surface, wherein a liquid release layer is applied on the bottom surface of the asphalt shingle instead of conventional backing particulates. The liquid release layer may help the shingle proceed through the manufacturing machinery without sticking and may prevent the adhesion of the bottom surface of the asphalt shingle to an adjacent shingle in a stack of shingles upon experiencing a pressure up to around four pounds per square inch, a temperature of around eighty degrees Celsius or below. The liquid release agent may also prevent adhesion of adjacent shingles in a stack at various temperature and pressures for at least fourteen days.
