What is the typical lifespan of asphalt shingles?

Asphalt shingles typically have a lifespan of 15 to 30 years, depending on various factors such as the quality of the shingles, the climate in which they are installed, and how well they are maintained. Higher quality shingles, often referred to as architectural or dimensional shingles, may last toward the upper end of this range, while standard three-tab shingles may wear out more quickly, especially if exposed to extreme weather conditions.

Proper installation and regular maintenance, including inspections and timely repairs, can help extend the life of asphalt shingles, further solidifying the expectation of them lasting between 15 to 30 years. Understanding these factors is crucial for homeowners and inspectors alike when assessing roof conditions and making recommendations for future action.
