Published lifespans are averages. In North Texas, sun, heat and hail are what usually decide how long a roof really lasts.

The InterNACHI life-expectancy chart lists about 20 years for 3-tab asphalt shingles, 30 years for architectural shingles and 40 to 80 years for metal. In Dallas–Fort Worth, intense sun and repeated hail often end a shingle roof’s life sooner, and insurers may cover an older roof at actual cash value.
| Roof covering | Typical life (InterNACHI) |
|---|---|
| Asphalt, 3-tab | About 20 years |
| Asphalt, architectural | About 30 years |
| Metal | 40 to 80 years |
| Clay or concrete tile | 100+ years |
These are estimates for typical conditions, not guarantees.
A “30-year” or “lifetime” shingle warranty describes what the manufacturer covers and how, often prorated, not how long the roof will last on your house. See roofing warranties explained.
Insurers inspect roofs when you apply and may charge more or refuse coverage based on the roof’s condition. As roofs age, some companies switch them to actual cash value coverage. See does insurance cover a new roof?
InterNACHI estimates about 30 years. In North Texas, heat and hail often shorten that.
InterNACHI lists 40 to 80 years for metal roofing.
It can. Some insurers move older roofs to actual cash value coverage, and a roof in poor condition might not be covered.
