The short answer
There is no single national limit. Many insurers start asking questions when an asphalt shingle roof reaches about 15 to 20 years, and some will not write a new policy on older shingle roofs. Metal, tile, and slate usually get more leeway. Condition matters as much as age.
Typical roof lifespans
| Roof type | Typical lifespan |
|---|---|
| Asphalt shingle (3-tab) | About 15 to 20 years |
| Architectural shingle | About 20 to 30 years |
| Metal | About 40 to 70 years |
| Clay or concrete tile | 50 years or more |
| Slate | 75 years or more |
| Flat or low-slope | About 10 to 25 years |
These are general ranges. Weather, installation quality, and upkeep change them a lot.
What insurers may do as a roof gets older
- Ask for a roof inspection or a roof certification
- Switch the roof to actual cash value coverage or a roof payment schedule
- Add a roof surcharge to your premium
- Decline to write a new policy, or decline to renew
What usually happens at each roof age
| Roof age | What often happens |
|---|---|
| 0 to 10 years | Rarely an issue. Most insurers offer full replacement-cost coverage. |
| 11 to 15 years | Usually still insurable. Some insurers start moving the roof to actual cash value coverage. |
| 16 to 20 years | Asphalt shingle roofs, usually built to last 20 to 25 years, may trigger an inspection, an aerial photo review, a surcharge, or coverage limits. |
| More than 20 years | Many standard insurers limit roof coverage, ask for a replacement, or decline to renew. Tile, slate and metal roofs are often treated differently. |
These are typical patterns, not rules. Each insurer and state sets its own, so the letter from your insurer is what counts.
Example: Florida
Florida law says insurers can’t refuse to write or renew a policy only because a roof is less than 15 years old. For older roofs, the insurer must allow an inspection, and if it shows at least 5 years of useful life left, roof age alone can’t be the reason. Citizens, Florida’s state-backed insurer, asks for a roof inspection on shingle roofs older than 25 years, showing at least 5 years of remaining life. Rules change, so confirm the current version.
What counts as roof age?
Usually the date of the last full roof replacement, not the age of the house. Small repairs normally don’t reset the clock. If your insurer has the wrong roof year on file, send proof and ask them to correct it.
Good to know
Keep proof of your roof date in one place: the permit, the roofer’s invoice, and the warranty. Not sure how old your roof is? See how to find out.

A local roofer can check your roof and tell you whether a repair, a roof certification, or a replacement makes sense. Free, with no obligation.

Common questions
Is a 20-year-old roof too old to insure?
Not always. It depends on the roof type, its condition, your state, and the insurer. A shingle roof in good shape may still be insurable, sometimes with an inspection or actual cash value coverage.
Does a metal roof help with insurance?
Often. Metal and tile roofs last longer, so insurers usually accept them at older ages. Some insurers also offer discounts for impact-resistant roofs.
What if my insurer’s roof age is wrong?
Send proof such as a permit or invoice and ask them to update their records in writing.
