Roofing material with surface treatment and shadow area

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.

What is claimed is: 
     
         1 . A roofing material comprising:
 a plurality of laminate layers, wherein a top laminate layer which at least partially overlaps a bottom laminate layer;   a surface treatment on portions of the top and bottom laminate layers; and   a shadow area on a top surface of the bottom laminate layer, adjacent to the top laminate layer, that is void of the surface treatment.   
     
     
         2 . The roofing material of  claim 1 , wherein each laminate layers comprises:
 a substrate; and   granules disposed on the substrate.   
     
     
         3 . The roofing material of  claim 1 , wherein a width of the shadow area, as a distance from the top laminate layer, is dependent on an application angle of an applicator configured to apply the surface treatment to the portions of the top and bottom laminate layers. 
     
     
         4 . The roofing material of  claim 3 , wherein the width of the shadow area is further dependent on a thickness of the top laminate layer. 
     
     
         5 . The roofing material of  claim 3 , wherein the surface treatment comprises a coating applied to the plurality of laminate layers. 
     
     
         6 . The roofing material of  claim 1 , wherein the surface treatment comprises a directional coating applied to the portions of the top and bottom laminate layers from an angle at which the top laminate layer that shields the shadow area on the bottom laminate layer.
