How Long Does a Roof Last? (And When Insurers Start to Worry)

The short answer

Most asphalt shingle roofs last about 20 to 30 years. Metal can last 40 to 80 years, and tile and slate can last far longer. But your insurer may start asking questions long before your roof wears out, often somewhere between 15 and 25 years for shingles. For insurance, the age that matters is usually the insurer’s cutoff, not the material’s full lifespan.

Is this you?

Your roof is 15 years old or more and your renewal is coming up.
You are not sure what your roof is made of or how much life it has left.
Your insurer mentioned the roof’s age or its remaining useful life (how many more years it should keep working).
You are helping a parent decide whether to repair, certify, or replace an older roof.

How long each roof material lasts

The table below uses two well-known guides. The first is the life expectancy chart from InterNACHI, a large home inspector association. The second is a 2007 study of home components by the National Association of Home Builders (NAHB). Both say these are estimates for roofs with normal wear and regular care, not promises.

Roof material	InterNACHI estimate	NAHB 2007 estimate	How insurers often see it
Asphalt shingles, 3-tab	About 20 years	20 years (all asphalt)	Questions often start around 15 years. See asphalt shingle roofs.
Asphalt shingles, architectural	About 30 years	20 years (all asphalt)	Many insurers apply the same age rules as 3-tab.
Metal	40 to 80 years	Not rated (copper: lifetime)	Often treated as a “hard” roof with longer limits. See metal roofs.
Clay or concrete tile	100+ years	Lifetime	Often given longer limits. See tile roofs.
Slate	60 to 150 years	50+ years	Often given longer limits.
Wood shakes or shingles	About 25 years	30 years	Many California insurers will not cover them because of fire risk.
Flat: built-up (tar and gravel)	About 30 years	30 years (coal and tar)	Some insurers want a minimum slope. See flat roofs.
Flat: modified bitumen	About 20 years	20 years	Same as above.
Flat: EPDM rubber	15 to 25 years	Not rated	Same as above.
Flat: TPO	7 to 20 years	Not rated	Same as above.

Notice the gap. An architectural shingle roof might last 30 years on paper, but an insurer may start treating it as old at 15 to 25 years.

Why the same roof lasts longer in some places

A roof does not age by the calendar alone. NAHB notes that roof life depends on local weather, how well the roof was built and designed, and maintenance. InterNACHI says hot climates drastically shorten the life of asphalt shingles, and that hail, tornadoes, and hurricanes can shorten the life of any roof.

Heat and sun. Shingles in hot, sunny places tend to wear out sooner than the chart suggests.
Hail and wind. Hail knocks off the protective granules on shingles, and strong wind can lift or tear them. One bad storm can take years off a roof.
Poor attic ventilation. The FORTIFIED program, run by the insurance-funded Insurance Institute for Business & Home Safety (IBHS), says curled shingles can point to poor attic ventilation or a poor install.
Shade and moisture. Moss and algae grow in shady, damp spots. Moss traps water against the roof.

So two roofs installed the same year can be in very different shape. That is why some insurers, and some state laws, look at condition as well as age.

Roof lifespan vs. insurer age limits

Insurers do not wait for a roof to fail. They set their own age rules, and those rules vary by company and state. A few real examples:

Florida law. Insurers may not refuse to write or renew a homeowners policy only because a roof is less than 15 years old. For a roof 15 years or older, the insurer must let you get an inspection first. If an authorized inspector finds 5 or more years of useful life left, age alone cannot be the reason to refuse coverage.
Citizens Property Insurance (Florida). Under rules that took effect in 2023, shingle and other soft roofs older than 25 years, and tile, slate, concrete, or metal roofs older than 50 years, need an inspection showing at least 5 years of remaining useful life. Citizens then extends coverage for up to 5 years at a time.
California. Insurance Business reported in May 2026 that Farmers’ filed guidelines show asphalt roofs older than 15 years may qualify only for actual cash value coverage. It also relayed reports that Mercury and Wawanesa generally do not insure roofs older than 25 years, with exceptions for tile and slate.

Actual cash value (ACV) means the insurer pays what your roof is worth after wear and tear, not what a new roof costs. On an older roof, that gap can be large. Our guide to ACV roof coverage explains it.

What to do at each stage

Under about 10 years. Keep your roof permit, invoice, and photos in one folder. This is your proof of roof age later.
About 10 to 15 years (shingles). Ask your insurer or agent, in writing, at what age they start requiring inspections or switching the roof to ACV. Have the roof looked at after any big storm.
15 to 20 years (shingles). Get an inspection that states remaining useful life in years. If the roof is in good shape, a roof certification may keep your coverage in place.
20 years and up (shingles). Start planning and saving for replacement before your insurer sets the deadline for you. Get quotes early so you are not rushed.
Tile, slate, or metal. Insurer limits are often longer, but repairs, storm damage, and flashing still matter. Ask your insurer which age limit applies to your roof type.

Good to know

Ask any inspector to write the remaining useful life as a number of years, not just “fair” or “good.” Florida law and Citizens both use that number, and many other insurers find it useful too.

Wondering how much life your roof has left?

A local roofer can look at your roof and give you a written estimate of its remaining useful life to share with your insurer. Free, with no obligation.

Common questions

Does a 30-year shingle mean my roof will be insured for 30 years?

No. The rating on the package is the maker’s estimate. Your insurer sets its own age rules and may look at condition. Many start asking questions at 15 to 25 years.

If only part of my roof was replaced, how old is my roof?

It depends on the insurer. Citizens in Florida, for example, bases roof age on the oldest part of the roof when the whole roof was not replaced at the same time. Ask your insurer how it counts.

Which roof lasts the longest?

Slate and clay or concrete tile have the longest estimated lifespans, often 50 years or more. Insurers usually give these hard roofs longer age limits than shingles.

Can a roof wear out faster than the chart says?

Yes. Heat, hail, wind, poor ventilation, and skipped maintenance can all shorten a roof’s life. That is why a roof’s condition matters as much as its age.
