摘要:
This invention is directed to a multi-layer laminated shingle, wherein each shingle layer has granule and bituminous coated web, with the layers laminated together and with the butt zone of the base layer disposed against a bottom surface of the tab zone of the secondary layer and with the tab zone of the base layer disposed against the bottom surface of the butt zone of the secondary layer. The shingle lends itself to having tabs spaced by voids. Because the tabs in the base layer are inverted, the base layer's butt zone is visible through voids in the tabs of the secondary layer. The method of making the shingle lends itself to complementally cutting out the tabs of two side-by-side shingles from a given line. Enhanced nailing area is provided, and stacking of shingles for packaging is facilitated.
