Abstract
A roofing shingle comprising a mat having regions of various thicknesses. A layer of asphalt-based material coats the mat and a layer of granules is deposited on the asphalt-coated mat. The variations in the thickness of the regions of the mat give the shingle differences in thickness corresponding to the thickness variations in the regions of the mat, thereby giving the shingle an appearance of depth.
