How long does a roof last?
A roof's lifespan comes down to one thing more than any other: what it's made of. Asphalt shingles — on roughly 80% of U.S. homes — last 15 to 30 years. Metal, tile, and slate can outlive the people who installed them. Below is what to expect by material, what shortens it, and what replacement actually costs in 2026.
How long does each roofing material last?
- Asphalt shingles (3-tab): 15–20 years. The most common and the shortest-lived.
- Asphalt shingles (architectural / dimensional): 25–30 years. Thicker, heavier, now the default on new builds.
- Wood shingles/shakes: 25–30 years, less in wet or fire-prone climates.
- Metal (standing seam): 40–70 years.
- Clay or concrete tile: 50–100 years (the tile outlasts the underlayment, which needs redoing sooner).
- Slate: 75–150+ years. Effectively permanent if maintained.
What makes a roof wear out faster?
Climate does most of the damage. Intense sun, big temperature swings, heavy snow load, and salt air all shorten the numbers above. So does poor attic ventilation (it cooks shingles from below), trapped debris, and deferred small repairs that let water find the decking. A south-facing slope in Arizona ages faster than a north-facing one in Oregon — same shingle.
How do I tell how old my roof is?
Three ways, easiest first: check the home's permit history (re-roofs usually pull a permit), look for the original spec or a receipt in your closing documents, or have a roofer read the granule loss and curling. If you bought the house, the inspection report often estimated remaining life. Almwell pulls permit and property records automatically and estimates your roof's age from them — no digging required.
What does a new roof cost in 2026?
For a typical single-family home (about 1,700–2,000 sq ft of roof area), replacement cost bands:
- Asphalt shingles: $6,000–$16,000
- Metal: $15,000–$40,000
- Tile: $15,000–$45,000
- Slate: $25,000–$60,000+
Your actual number depends on pitch, layers to tear off, region, and material — which is exactly the kind of thing worth knowing before it's an emergency. See our methodology for how we estimate component ages and cost bands.
When should I start budgeting for it?
If your roof is asphalt and past year 15, start setting money aside now. A roof is the single most expensive predictable home repair most owners face, and it almost never fails on a convenient schedule. Knowing your roof's age turns a $12,000 surprise into a line item you've been funding for years. See our guide on how much to budget for home maintenance.
