How Old Can a Roof Be Before Insurance Says It's Too Old in California?

No State Roof Age Limit Exists Yet

We look at a lot of tired roofs in Ontario, and the question we hear most after a homeowner opens a renewal letter is simple. How old is too old? The answer is that it depends on the company, not the state.

In May 2026, Insurance Business reported on a review of the underwriting rules filed by the 20 largest home insurers in California, which wrote 90 percent of the state's homeowners premiums in 2024 (Insurance Business, May 26, 2026). The rules were all over the map. Mercury and Wawanesa generally will not insure a home with a roof older than 25 years, but tile and slate roofs are the exception. Farmers may limit asphalt roofs older than 15 years to actual cash value instead of full replacement cost. Many carriers will not take wood shake at all, and many want flat roofs to have enough slope to drain.

So a 22 year old shingle roof can be fine with one company and a deal breaker with the next. That is why the same street in Ontario can have one neighbor who renewed with no trouble and another who got a letter.

Most insurers look at two things. The age of the roof, and what it looks like. Age comes from your application, permit records or the year the house was built. Condition now often comes from aerial photos, and the same article noted a bill to regulate how insurers use aerial and satellite images (Insurance Business).

Why Tile and Shingle Roofs Get Treated Differently

The InterNACHI life expectancy chart for home inspectors lists a 3 tab asphalt shingle roof at about 20 years, an architectural shingle at about 30, and clay or concrete tile at 100 years or more (InterNACHI chart). Those are guides for normal wear, not promises. Insurers know the gap, which is why some of them carve out tile from their age rules.

On a tile roof in the Inland Empire, the catch is the paper. The tile can last a lifetime, but the paper under it does not. On the tract homes built in Ontario, Rancho Cucamonga, Chino and Eastvale in the 1980s, 1990s and 2000s, we often find tile that looks fine from the street and underlayment that is dried out and torn. An aerial photo cannot see that. A leak from worn out paper is wear, and wear is the kind of damage home policies usually do not pay for.

Older shingle ranch homes near downtown Ontario, Montclair, Upland and Pomona are the ones that run into age rules first. Hot dry summers and strong sun bake shingles, and a 20 year old shingle roof here often shows its age in curled edges and lost grit.

Wood shake is its own problem. The California Department of Insurance lists a Class A fire rated roof as a wildfire safety step and says wood shake shingles are not Class A rated, while asphalt shingle, concrete or clay tile and metal mostly qualify (CDI Safer from Wildfires). If you still have shake, expect trouble with most carriers no matter its age.

Replacement Cost vs Actual Cash Value on an Old Roof

Losing your policy is the worst case. The more common case is quieter. The insurer keeps you but changes how it pays for the roof, and you only find out when you file a claim.

Replacement cost pays what it costs to repair or replace the damage without taking anything off for age. Actual cash value takes depreciation off first. California law says that when a policy requires you to rebuild to collect full replacement cost, the insurer pays actual cash value first and then the rest once the work is done (Insurance Code 2051.5). The same law gives you at least 12 months from the first payment to collect the rest, or at least 36 months for a loss tied to a declared state of emergency.

Say a storm damages a roof that would cost $20,000 to replace, and the insurer judges that roof to be 80 percent used up. On replacement cost you collect about $20,000 minus your deductible. On actual cash value you collect about $4,000 minus your deductible. Same roof, same storm, a very different check.

Read your renewal for words like roof surfacing, roof payment schedule, actual cash value roof, or a separate wind and hail deductible. Insurance Code 678 requires a renewal offer to spell out any reduction of limits or coverage that is being removed (Insurance Code 678). If you see one of those changes, ask your agent what it means in dollars for your roof before the policy starts.

Your Rights Today If You Get a Nonrenewal

Under the law in force as of October 2026, an insurer that will not renew your home policy has to send the notice at least 75 days before the policy ends (Insurance Code 678). The notice must give the specific reason or reasons, a phone number for the company, and a statement that you can ask the Department of Insurance to review it. CDI can be reached at (800) 927-HELP (4357) or insurance.ca.gov.

If the insurer misses the 75 day deadline, your current policy stays in force with no changes for 75 days from the day the notice was sent (Insurance Code 678). Check the postmark and your policy end date the day the letter arrives.

When the reason is your roof, call the company and ask exactly what it saw and what would change its mind. Sometimes a repair or a written roof report is enough. Sometimes the answer is a new roof or a new company. Either way, start shopping right away, because a new policy can take time to line up.

What Changes on January 1, 2028

On September 27, 2026, Governor Newsom signed SB 1301 into law (SB 1301 bill text). Most of it starts January 1, 2028. It does not help with a letter you get this year, but it is worth knowing now.

The roof age rule. An insurer may not refuse to issue or renew a home policy, or decide you are not eligible, solely because of the age of the roof if you get and pay for an independent roof inspection that confirms at least five years of useful life left. The law also says insurers can still take roof age into account. So age can still affect your price and terms. It just cannot be the only reason you get turned away when a report backs up the roof.

More notice and a chance to fix it. The nonrenewal notice moves from 75 days to 90 days. If the problem is something you can fix, like a worn roof, the insurer must send notice at least 120 days before the policy ends, explain what would qualify you to renew, and give you at least 90 days to do the work or send proof (SB 1301).

You get to see the evidence. The insurer must give a plain language reason and the nonaerial images (photos not taken from the air) it relied on, and must hand over any inspection reports it used within 15 days of your request (SB 1301). If an aerial photo got your roof wrong, that is your opening.

If You End Up on the FAIR Plan

The California FAIR Plan is the fallback for homes that cannot get a regular policy. The Department of Insurance describes it as a limited fire policy with limits up to $3 million per location for homes, and says you need a separate Difference in Conditions policy for things like water damage, liability and theft until a fuller FAIR Plan option is finished (CDI FAIR Plan page).

The roof matters here too. The FAIR Plan's replacement cost addendum, still posted on its site in October 2026, says a home built more than 25 years ago is not eligible for dwelling replacement cost unless the roof was updated in the last 25 years (FAIR Plan form CFP-RCAD-2). The form asks for the year the roof was updated or replaced. Any Ontario home built before 2001 is past 25 years old now, which covers most of the 1980s and 1990s tile tracts. If your roof is original, you may only be able to buy actual cash value coverage on the house.

CDI also says FAIR Plan homeowners can get a discount on the wildfire part of the premium for hardening the home (CDI FAIR Plan page), and a Class A roof is one of the listed steps (CDI Safer from Wildfires).

What a Roof Inspection or Certification Does for Insurance

A roof inspection does not make an old roof new. What it does is replace a guess with facts. The insurer may only know the year the house was built and what a photo from the air shows. A written report with photos shows the real condition, the remaining life and what was fixed.

That matters most for tile. A 30 year old tile roof with a new underlayment re-lay is a very different risk from a 30 year old tile roof with the original paper, and the year built on your application does not show the difference. Keep the invoice, the permit and photos from any re-lay or replacement. That is your proof of when the roof was updated.

A roof inspection with a written report is also the kind of document the 2028 law has in mind. The law says independent and paid for by you, and it does not spell out who counts, so ask your insurer what kind of report it will accept before you book one.

Repair, Re-Lay or Replace Before Renewal?

If the roof is sound and only a few spots are worn, a repair and a clean report is the cheapest way to keep your policy. If it is a tile roof with tired paper, a tile underlayment re-lay reuses your tile and resets the clock on the part that actually leaks. If it is an old shingle roof past 20 years with curling and bald spots, a full roof replacement is often the move that fixes both the leaks and the insurance problem.

Do not let a renewal deadline rush you into signing with the first door knocker. Get the insurer's reason in writing, get a real look at the roof, and then decide. If you want a written estimate and photos of what your roof actually needs, call Ontario Roofing at (909) 404-9464. The phone is answered 24 hours.
