How Long Does a Roof Last? Lifespan by Material
An asphalt shingle roof typically lasts 20 to 30 years. Metal, tile and slate last far longer. Climate, ventilation and installation quality can move any of these numbers by years.
Lifespan by material
The ranges below assume a proper installation and normal maintenance. Hot climates, poor attic ventilation and repeated hail shorten the life of shingle roofs in particular.
| Item | Guidance | Notes |
|---|---|---|
| 3-tab asphalt shingles | 15 to 20 years | $7,400 to $11,200 to replace |
| Architectural asphalt shingles | 20 to 30 years | $9,400 to $15,200 to replace |
| Metal (standing seam) | 40 to 60 years | $20,400 to $33,200 to replace |
| Wood shakes | 20 to 35 years | $16,400 to $31,200 to replace |
| Concrete tile | 40 to 50 years or more | $16,400 to $35,200 to replace |
| Slate | 75 to 100 years or more | $30,400 to $71,200 to replace |
What shortens a roof's life
Poor attic ventilation cooks shingles from below. Overhanging trees drop debris and hold moisture. Ice dams lift shingles. Hail bruises them. A second layer installed over the first traps heat and hides decking problems. Installation errors, especially at flashing, cause most early leaks.
How to tell how old your roof is
Check the permit history with your city, ask the previous owner or look for a dated receipt. If none exists, a roofer can estimate age from granule loss, shingle flexibility and the condition of flashing and vents.
Signs it is near the end
Granules collecting in gutters, curled or cracked shingles, bald spots, daylight in the attic, sagging areas and leaks after ordinary rain.
Common questions
How long does an asphalt shingle roof last?
About 20 to 30 years for architectural shingles and 15 to 20 for 3-tab, depending on climate and ventilation.
How long does a metal roof last?
Standing seam metal commonly lasts 40 to 60 years, and copper or zinc longer.
Should I replace my roof before it fails?
Replacing a roof that is visibly worn but not yet leaking avoids water damage to decking, insulation and ceilings, which can cost more than the roof.
