How long does a asphalt shingle roof last?

A standard asphalt shingle roof lasts about 20 to 25 years. Enter the year it was installed and this calculator estimates the remaining life and when to start a replacement fund, so you can plan the job instead of reacting to a leak.

Architectural shingles and good attic ventilation reach the top of the range; cheap three-tab shingles and poor ventilation fall short. Curling, cracked, or missing shingles and granules in the gutters are signs the roof is aging out.

These lifespans are typical ranges for a well-maintained unit. Hard water, heavy use, and skipped maintenance shorten them; regular service extends them. Use the estimate to plan a replacement fund, not as a firm expiration date.

Frequently asked questions

How long does an asphalt shingle roof last?
Asphalt shingle roofs last about 20 to 25 years. Architectural (dimensional) shingles and well-ventilated attics reach the high end, while three-tab shingles in harsh sun or poor ventilation wear out sooner.
What are the signs I need a new roof?
Curling, cracked, or missing shingles, bald spots where granules have worn off, granules collecting in gutters, and any interior water stains all point to a roof nearing replacement.
