摘要： One aspect of the disclosure is roofing shingle including a shim layer having a top surface, a first side edge, and a second side edge positioned opposite the first side edge. The roofing shingle also includes a top shingle layer at least partially laminated to the top surface of the shim layer, where the top shingle layer includes a first side edge offset a sidelap distance from the first side edge of the shim layer such that a side portion of the top surface of the shim layer is exposed, and a second side edge extending beyond the second side edge of the shim layer so as to overlap the second side edge of the shim layer by the sidelap distance.

摘要： The present disclosure relates generally to roofing products, for example, suitable for use covering and protecting the roofs of structures. The present disclosure relates more particularly to a roofing product including an upper section and an exposed section. The roofing product includes a substrate having a top surface and a bottom surface, and a plurality of zones of roofing granules disposed on the top surface of the substrate. The plurality of zones includes first, second and third zones within the exposed section. The first zone includes a first collection of algae-resistant roofing granules and has a first algae-resistance intensity. The second zone includes a second collection of algae-resistant roofing granules and has a second algae-resistance intensity. The third zone has a third algae-resistance intensity that is different from the first algae-resistance intensity.
