A roofing material comprising an upper surface and a lower surface, wherein the upper surface includes reduced-particle size granules and may further include a reduced- thickness face coating. The thickness of the upper surface is related to the particle size of the granules deposed on the face coating. A smaller particle size granule than those used in traditional roofing shingles is utilized in the upper surface which may allow for a reduced-thickness face coating while not sacrificing the retention of the granules on the surface of the roofing material or desired physical characteristics. The face coating may include a reduced amount of filler material, such as mineral fillers, than face coatings of traditional roofing materials.
