Abstract

A roofing material includes a plurality of laminate layers and a surface treatment. The plurality of laminate layers includes a top laminate layer which at least partially overlaps a bottom laminate layer. The surface treatment is on portions of the top and bottom laminate layers. A shadow area is created on a top surface of the bottom laminate layer, adjacent to the top laminate layer, that is void of the surface treatment. This shadow area has a distinct visual appearance from the other portions of the top and bottom laminate layers that are subjected to the surface treatment.
