The most common type of roofing material in the United States, asphalt shingles generally last between 15 to 30 years, depending on their quality and installation. Three-tab asphalt shingles are the most basic option and tend to have a shorter lifespan, typically around 15 to 20 years. On the other hand, architectural shingles, made from a thicker layer of asphalt and designed to mimic the look of more expensive materials, can last up to 30 years. Homeowners should consider factors such as climate, maintenance, and the quality of installation, as these can significantly influence the longevity of asphalt shingles.
