ABSTRACT:
A method is taught of making a multiple-layer, three-layer shingle, in which a base shingle layer is formed by separating a first shingle layer longitudinally into halves, with adhesive applied longitudinally to the halves of the base shingle layer, and with a second shingle layer then being separated into halves to function as secondary shingle layers that are applied over the adhesive on the base shingle layers, to secure them together, and with a third shingle layer being separated longitudinally into halves and then transversely into segments, with adhesive being applied transversely over granules on the top surface of the secondary shingle layer, with the segments of the third shingle layer forming a top shingle layer, with such segments being selectively applied to yield predetermined design effects. The result is to produce a three-layer laminated shingle, with the layers adhered together with granules on the top surfaces of the layers sandwiched therebetween. The secondary shingle layer may have a lower edge of its tabs foreshortened to reveal granules on the top surface of the base layer, which granules are preferably darker for contrasting effect.
