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.
The expected lifespan of an architectural asphalt shingle roof, often called a dimensional shingle roof, is 24 to 30 years in Florida. Architectural shingles start with a heavier mat base than a standard 3-tab shingle, typically fiberglass that has been coated with asphalt.
