Roofing tile with weather durable coloring matter

摘要

A synthetic roofing material for a roofing tile and a method of extruding a resinous polymeric precursor of an exterior polymeric sheet for one or more roofing tiles; and applying a weather durable coloring matter on a surface of the precursor, wherein the cooling matter comprises one or more pigment colors in a variegated surface coloration pattern, which simulates a distinctive coloration of a natural material. The precursor is impressed with surface topography features and a surface roughness that simulate the surface features of the natural material.

1. A method of making a roofing tile, comprising:
extruding a precursor of a capstock layer; providing said precursor of a capstock layer with an extruded roofing tile profile having a butt edge, a single nailing edge and substantially planar top and bottom surfaces; applying weather durable coloring matter comprising ink or paint in a predetermined coloration pattern onto at least said top surface of said precursor of a capstock layer, vacuum molding an impression into at least said top surface of said precursor of a capstock layer; applying a base layer on the precursor of the capstock layer, the base layer adapted to form a flat planar interior surface; and cutting a plurality of side edges into the extruded roofing tile profile of the precursor of a capstock layer and the base layer to form separate shingles attached to the single nailing edge, wherein a first shingle is thicker and shorter in length to the butt edge than a second shingle, wherein each shingle is formed with substantially the same volume of polymeric material, wherein the butt edge has a topography to provide a jagged appearance.
