What is Asphalt Shingles?
Roofing Glossary · Materials
Definition
The most widely installed residential roofing material in North America, consisting of a fiberglass or organic mat coated with asphalt and surfaced with mineral granules. Asphalt shingles come in two primary profiles — 3-tab and architectural (dimensional/laminate) — and offer Class A fire ratings with lifespans of 15 to 30 years depending on grade. They are valued for affordability, wide color availability, and ease of installation.
