Abstract
A series of roofing shingles (200, 240, 260, 280) are disclosed which have multiple tabs across the exposed width of the shingle. A polymer foam layer is bonded to an asphalt shingle material to form the roofing shingle. The polymer foam is thicker at certain of the tabs than others to provide a pleasing layered appearance to the roof. The tabs can also be varied in width and length relative to adjacent tabs.
