The most popular roof in the country is hands down a composition roof.
What you should know about composition roofing.
The most widely used roofing material is the composition shingle. These shingles come in a variety of colors, designs and sizes. Depending on the product, the warranty can be anywhere from 15 to 50 years or a “Lifetime.” Composition shingles are also called composite, asphalt, or fiberglass shingles. They start with a fiberglass base mat and are then dipped in asphalt and coated with mineral granules to add color and texture. Roughly 75% of roofs in Seattle are composition.
