How Long Does a Roof Last? Lifespan by Roofing Material

Quick answer: Asphalt shingles typically last 15 to 30 years, wood shake 15 to 30, metal 40 to 80, and tile and slate 50 years or more, but climate, attic ventilation, installation quality and storms can cut those numbers. Replace a roof when its condition says so, such as widespread damage, granule loss or recurring leaks, rather than by age alone. Check your insurer's roof-age rules and your local permit rules first, because both vary by state.

Roof lifespan by material

The first factor in how long a roof lasts is what it is made of. These are typical ranges under normal conditions with regular maintenance. Sources differ, so treat them as ranges, not promises.

Low-slope roofs, found on additions and porches, use membranes whose life varies by product. Check the manufacturer's warranty rather than relying on a generic number.

What shortens a roof's life

Climate is the biggest variable, and it works differently in each region.

• Heat and sun: In a 10-year IBHS test of asphalt shingles in South Carolina, Wisconsin and Ohio, differences in solar radiation, temperature swings and latitude changed how the shingles aged. The U.S. Department of Energy says reflective "cool" roofs save the most in hot climates, and can raise heating costs in cold ones.
• Humidity: Moss and algae growth shorten life in damp regions, and algae-resistant shingles exist.
• Freeze and snow: Warm attic air melts snow, which refreezes at the eaves as an ice dam. MI Ready, Michigan's preparedness program, recommends sealing air leaks, R-30 or better attic insulation (R-38 in northern areas) and ventilation from the eaves to the ridge.
• Hail and wind: See the regional table below.
• Poor attic ventilation, bad installation and neglected maintenance: GAF lists all three, plus severe storm damage, among the causes of early aging.

IBHS also found that shingles often lose wind resistance between years 5 and 10 as the sealant bond weakens, and that a shingle's initial wind rating does not predict how it will age.

Signs your roof needs attention

You do not need a leak to know a roof is aging. From the ground, or with binoculars, look for:

• Missing, buckling, curling, cracking or torn shingles
• Heavy granule loss, such as grit in the gutters
• Sagging along the roofline
• Recurring or widespread leaks, or daylight in the attic
• Lifted or cracked flashing around chimneys, vents and skylights
• Moss or dark streaks

The National Roofing Contractors Association says homeowners should inspect only from ground level because the risk of falling is too great, and recommends hiring a professional roofer to inspect as soon as possible after storm damage.

Repair or replace

No single rule fits every roof. GAF suggests replacement when you see widespread damage, recurring leaks or a roof past 20 years with extensive damage. Isolated damage on a roof with most of its life left is usually a repair.

• Repair fits localized damage, a failed flashing or a few lost shingles on a roof in its middle years.
• Replace fits widespread wear, repeated repairs, or a roof near the end of its expected life.
• Check for layers. Many jurisdictions follow the model code: a new roof cannot be installed over an existing roof that already has two or more layers of roof covering. Kettering, Ohio; Arlington, Texas; and Yonkers, New York all apply that wording, which means a full tear-off.
• Storm damage is different from wear. Texas's insurance department notes that insurers will not pay for replacement just because a roof is old or worn.

What replacement costs in 2026

Cost surveys differ in scope, so use these as a range and get at least three written local quotes.

The Cost vs Value report uses a defined project specification, which is why its figures run far above the surveys. It reports resale value recouped at 68 percent for asphalt and 50 percent for metal.

By material, Fixr lists installed prices per square foot of roughly $3 to $15 for asphalt, $4.50 to $40 for metal, $10 to $25 for clay tile, $7 to $30 for slate and $4.50 to $13.50 for wood. HomeAdvisor lists removal and disposal at $1,500 to $4,500 and permits at $100 to $1,400. Size, pitch, local labor and the condition of the roof deck move the total more than the shingle brand does.

How this varies by region

How insurers and permits differ by state

Insurance rules are set by each state's insurance department, and companies set their own roof-age policies within them. Confirm details with your agent and your state insurance department.

• Nationally: Triple-I says that if a roof is over 20 years old, most insurers require it to pass an inspection when you apply, and may limit older roofs to actual cash value (ACV), which subtracts depreciation, instead of replacement cost.
• Texas: The Texas Department of Insurance says insurers may move a roof from replacement cost to ACV as it ages, wind and hail deductibles can differ from other deductibles, and your policy might not pay if the roof is in poor condition. It tells owners to ask whether the roof age and material on the policy are correct.
• Oklahoma, Kentucky, Tennessee: United Policyholders reports a shift toward ACV roof coverage and roof payment schedules in states with costly wind and hail losses, including Allstate's House & Home policy in 27 states.
• Florida: Statute 627.7011 says an insurer may not refuse to issue or renew a policy solely because of roof age if the roof is under 15 years old, and a roof of 15 years or more with at least 5 years of useful life remaining per an inspection is also protected.
• California: The Department of Insurance's Safer from Wildfires regulation requires insurers to offer discounts for mitigation actions, including a Class A fire-rated roof. Discounts vary by insurer.
• FORTIFIED roof states: Alabama, Louisiana, Kentucky, North Carolina, Oklahoma, South Carolina and Florida run grant programs for storm-resistant roofs, mostly capped at about $10,000, and Alabama and Kentucky require insurers to offer related discounts. Programs and funding change, so check the current status.

Permits also vary. Kettering, Ohio, says most standard reroofing needs no permit, though approvals may be required depending on scope. Arlington, Texas, requires a permit issued before work starts and a contractor registered with the city. Yonkers, New York, charges a $125 base fee plus $15 per $1,000 of estimated cost. Ask your local building department, and check your state licensing board for contractor requirements.

Track your roof in Steadwell

Add the roof as an asset with its material, install year and contractor, and keep the invoice and roof warranty with it. The home condition assessment takes photos of a roof or gutters and returns a 1 to 5 grade with a years-left estimate, which you review before it saves. It is AI-assisted and available on Plus and Pro, so it does not replace a roofer's inspection. The free home insurance tracker stores your policy, deductible and renewal date. Our seasonal home maintenance checklist covers when to look at the roof and gutters.
