Is there a roof age limit for home insurance in California?

No. Each insurer decides which roofs it will cover, and the rules differ from one insurer to the next. A standard insurer files those rules with the Department of Insurance along with its rates.

In May 2026 the San Francisco Chronicle compiled the filed rules of the state's 20 largest home insurers, which together wrote 90% of the business in 2024. Nearly all restrict roofs by material, slope or age.

Where a rule names an age for asphalt or composition shingle roofs, it is mostly 20 or 25 years. Tile, slate and some metal roofs get longer limits or none.

Your insurer's rule is not secret. In 2018 the Department's general counsel wrote that rules filed with a rate application must be open to public inspection, even if marked confidential. Ask your insurer or agent for its current roof rule in writing.

Wood roofs top the list. The Chronicle found wood shake and wood shingle roofs ineligible "for the majority of major insurers," for some everywhere and for others only in high wildfire-risk areas.

Fire is the reason. CAL FIRE calls the roof "the most vulnerable part of your home" and says a wood shingle roof puts a home "at high risk."

Age and water damage come next. Among the most common bans, the Chronicle found, were roofs "beyond their estimated life expectancy" and flat roofs without proper drainage. Several insurers also refuse roofs with more than two layers of shingles.

Insurers also look from the air. In March 2025 the Department of Insurance said it had investigated complaints in which "insurers used imprecise drone or satellite photos to assess roof conditions."

An actual cash value roof is covered at its used value, not the cost of a new one. Actual cash value pays what it would cost to replace the roof, minus "a fair and reasonable deduction for physical depreciation," as California's Insurance Code puts it.

An insurer can keep an older roof on the policy this way instead of refusing it. The Chronicle reported that at one large insurer, asphalt roofs older than 15 years qualify only for actual cash value coverage.

The FAIR Plan has a roof rule too, the Chronicle reported in May 2026. For a home more than 25 years old, full replacement cost requires a roof replaced within the last 25 years, or the Plan offers only actual cash value. The Plan's current dwelling policy form does not state that rule.

Read your declarations page and any roof add-on. If the roof is covered at cash value, ask what a newer roof would change, before a claim rather than after.

A non-renewal notice must be mailed or delivered at least 75 days before the policy ends. It must give "the specific reason or reasons for the nonrenewal."

California's insurance privacy law also requires the specific reasons in writing when an insurer turns down or non-renews a home. The 75-day rule explains the notice clock.

SB 1301, signed September 27, 2026, makes non-renewal notices come at least 90 days ahead on and after January 1, 2028. The insurer must explain the grounds in plain language and share the images it relied on, other than aerial ones. On request, it must also send any inspection report it relied on within 15 days.

On and after January 1, 2028, an insurer must tell you about a problem you can fix at least 120 days before the policy ends. You then get at least 90 days to fix it. If the insurer verifies the fix, you qualify for renewal.

On and after January 1, 2028, an inspection can also protect you. Insurance Code section 676.14 then bars an insurer from refusing to issue or renew a policy "solely on the basis of the age of the roof."

On and after January 1, 2028, the insurer may still weigh the roof's age. The rule protects you when you pay for an independent roof inspection that "confirms at least five years of useful roof life remaining."

Get the facts in writing. Ask a licensed roofer for a written report of the roof's age, material and remaining life. A Santa Cruz roofer told the Chronicle that many clients with insurance problems come for a letter vouching for their roof's age.

Keep the permit and invoice from any roof work. California requires a roof installer to give the owner a certification of the roof covering's fire rating, so ask for it.

If you replace the roof, choose Class A, the highest fire rating. In a Very High fire hazard severity zone, state law generally requires at least Class A when more than half the roof is replaced within a year.

Class A also counts toward discounts. It is the first item on the Department's Safer from Wildfires list, which standard insurers must recognize, and the FAIR Plan lists it among its own discounts. What home hardening earns covers the rest of the list.

Some insurers now require it. One large California insurer's own website says, "Your roof must be a Class A fire-rated roof."

State Farm's filing to resume new homeowners applications, announced in September 2026, covers homes that meet IBHS Wildfire Prepared Home standards.

Those standards require a Class A roof, permit no wood roofs and cover much more than the roof. A Wildfire Prepared Home designation is for detached single-family homes, modular homes and manufactured homes built after July 1994, on a permanent foundation and three stories or fewer.

Search before you spend. United Policyholders' Amy Bach told the Chronicle that homeowners dropped over a flat roof should get quotes from at least two other insurers before costly construction.

They set their own rules. Specialty insurers are not licensed by the State of California. Their prices and roof rules are not filed with the Department, which lets them take some homes standard insurers turn down.

Search standard insurers first, then specialty insurers (the technical name is surplus lines). The FAIR Plan is the fallback for homes neither will cover.
