Also known as laminated or dimensional shingles, architectural roofing shingles are among the highest quality roofing products made. Traditionally, they are composed of a heavy fiber glass mat base and ceramic-coated mineral granules that are tightly embedded in carefully refined, water-resistant asphalt.
