Every part of your home has a lifespan. How long does a roof last? About 20 years for asphalt shingles. A furnace, 15 to 18. A dishwasher, about 9. Knowing these numbers helps you budget for repairs, and in California’s tough insurance market, it also affects which carriers will insure your home, what you pay and how a claim is paid.
Typical lifespans of home components
These ranges come from a study of home component life expectancy by the National Association of Home Builders and Bank of America (2007). Actual lifespans depend on quality, installation, maintenance and climate, and California’s heat and sun can shorten roofs and exterior paint.
| Component | Typical lifespan |
|---|---|
| Roof (asphalt shingles) | About 20 years |
| Exterior paint | Up to 15 years |
| Windows | 15–30 years |
| Furnace | 15–18 years |
| Heat pump | About 16 years |
| Air conditioning unit | 10–15 years |
| Asphalt driveway | 15–20 years |
| Wood deck | 10–15 years |
| Carpeting | 8–10 years |
| Kitchen faucet | About 15 years |
| Tub and shower faucets | 20+ years |
| Range | 13–15 years |
| Refrigerator | About 13 years |
| Dryer | About 13 years |
| Washing machine | About 10 years |
| Dishwasher | About 9 years |
| Smoke detectors and security systems | 5–10 years |
| Electrical switches and outlets | 10+ years |
| Kitchen cabinets | About 50 years |
| Shower enclosure | About 50 years |
| Wood or stone flooring | 100 years |
| Toilet | Lifetime |
Garage doors, fences and other structures
The parts of your property outside the house wear out too, and they’re insured differently. Fences, detached garages, sheds and gates usually fall under your policy’s other structures coverage, which is often set at a percentage of your dwelling limit. Typical lifespans (industry estimates; only the garage door opener comes from the NAHB study):
| Item | Typical lifespan |
|---|---|
| Garage door opener | 10–15 years |
| Steel garage door | 20–30 years |
| Wood garage door | 15–30 years, with regular sealing and paint |
| Wood fence | 15–20 years |
| Vinyl fence | 20–30 years |
| Chain-link fence | 15–20 years |
| Wrought iron or steel fence | 20+ years, with rust maintenance |
In wildfire country, a wood fence matters for more than looks. A wood fence or gate that connects to your house can carry fire right up to it. Fire-safety guidelines recommend a noncombustible section, such as metal, where a fence meets the home. It’s one of the things we look at during a Wildfire Insurability Walk-Through, along with your garage door’s seal against embers. For more on the area right next to your home, see Zone Zero in California.
Check your other structures limit, too. If you have a long fence line, a detached garage or a workshop, a limit set years ago may not cover replacing them at today’s prices.
Why your roof’s age matters most for insurance
Your roof is the single biggest factor in how insurers view your home. Many carriers ask for the roof’s age on every quote, and some limit or decline coverage once a roof passes a certain age or shows wear. Others may settle roof damage at actual cash value instead of replacement cost on older roofs. We cover this in depth in Roof Age and Home Insurance in California.
In wildfire country, the roof’s material matters as much as its age. A Class A fire-rated roof is one of the key home-hardening features under California’s Safer from Wildfires program, and it can help with both insurability and discounts.
If your roof is 15 years or older, it’s worth knowing before you shop for insurance or list your home for sale. Keep your roofing invoice or permit. Proof of a newer roof can open doors with carriers.
How age affects a claim: depreciation
If your policy pays actual cash value, the insurer deducts depreciation for wear and age, and these lifespans are what that math is based on. A 15-year-old roof with a 20-year lifespan has used up most of its useful life, so an ACV payment for it will be much lower than the cost of a new roof.
California law limits depreciation to parts of a home that normally wear out and get replaced, like roofs, paint, flooring and appliances. Long-lasting parts like the foundation and framing generally aren’t depreciated, and labor can’t be. With a replacement cost policy, you recover the depreciation when you repair or rebuild.

Systems carriers ask about
Beyond the roof, these are the items most likely to come up when you apply for coverage (see also Insuring an Older Home in California):
- Electrical: very old wiring and certain older electrical panels can limit your carrier options. Updated wiring helps.
- Plumbing: older supply lines and some older pipe materials raise water-damage concerns. Updated plumbing and leak detectors can help.
- Water heater: typically lasts about 8 to 12 years. California requires water heaters to be strapped for earthquakes, and a leaking one is a leading cause of water claims.
- Heating and cooling: a furnace or AC near the end of its life is a maintenance item, but an updated system shows a well-kept home.
Planning a home sale or purchase?
For sellers, updated roofs and systems make a home easier to insure, which makes it easier to sell (more tips for sellers). For buyers, knowing a roof’s age early prevents a surprise during escrow, when coverage has to be in place before closing.

Frequently asked questions
How long does a roof last?
An asphalt shingle roof typically lasts about 20 years, though California’s heat and sun can shorten that. Tile and metal roofs generally last longer.
Does the age of my roof affect my home insurance in California?
Yes. Most carriers ask for roof age, and some limit or decline coverage on older roofs or pay roof claims at actual cash value. A newer Class A fire-rated roof can improve your options in wildfire areas.
How long does a fence last?
A wood fence typically lasts 15 to 20 years, vinyl 20 to 30 years and chain-link 15 to 20 years. Fences are usually insured under your policy’s other structures coverage.
How long does a garage door last?
A steel garage door typically lasts 20 to 30 years, and a garage door opener 10 to 15 years.
What is depreciation in a home insurance claim?
Depreciation is a deduction for age and wear on parts of a home that normally get replaced, like a roof or flooring. Actual cash value policies subtract it. Replacement cost policies pay it back when you repair or rebuild.
What home systems do insurers ask about?
Usually the roof, electrical wiring and panel, plumbing, water heater and heating system. Updates to any of these can make a home easier to insure.
Should I check insurability before selling my home?
Yes. Knowing early how carriers view your roof and systems helps avoid surprises during escrow, when the buyer needs coverage in place before closing.
