A non-renewal letter that blames the age of your roof is often not really about the condition of your roof. In California, roof age and home insurance have become the same conversation, and not for reasons that have much to do with your house. Carriers have spent several years retreating from the California homeowners market, and roof age is a clean, defensible underwriting line to draw. Los Gatos Roofing has walked plenty of roofs with genuine service life left that a carrier simply would not accept.
That is an uncomfortable thing for a roofing company to say out loud, because the easy version of this conversation ends with us selling you a roof. The honest version starts with understanding what the letter actually is, what California law requires it to tell you, and what your real options are before you spend thirty thousand dollars solving a problem that may not be a roofing problem.
One note up front: Los Gatos Roofing is a roofing contractor, not an insurance advisor. Anything specific to your policy belongs with your agent, broker, or the California Department of Insurance.
Why Roof Age Became the Mechanism in California
California’s non-renewal rate reached a multi-decade high in 2024 at 3.18 percent, and the January 2025 Palisades and Eaton fires added roughly $30 billion in insured losses on top of an already strained market. Carriers responded by tightening what they would write, and roof age, roof material, brush score, and ZIP code became the filters. Roof age is easy to verify from a permit record and easy to apply uniformly, which is exactly why it gets used.
The market has loosened somewhat in 2026. Several large admitted carriers have reopened or expanded California homeowners availability under the Department of Insurance’s Sustainable Insurance Strategy, and brokers have reported meaningful volumes of new business moving back into admitted markets that were closed in 2023. That is real progress, and it does not change the fact that a twenty-two-year-old roof still gets flagged.
The Department also issues mandatory moratoriums after a declared wildfire emergency, barring cancellation and non-renewal for one year in the affected area. Those orders are tied to the specific ZIP codes named in each bulletin, and they protect against non-renewal based on wildfire risk, not roof age, so they generally will not help a homeowner whose notice cites the roof.
What a California Non-Renewal Notice Has to Tell You
California Insurance Code Section 678 requires an insurer to give at least 75 days’ written notice before non-renewing a residential property policy, and that notice must state the specific reason or reasons for the non-renewal. It also must include a phone number for the insurer’s consumer inquiry representatives. If the carrier fails to give 75 days’ notice, the existing policy stays in force, unchanged, for 75 days.
Read the stated reason carefully, because “roof age” and “roof condition” are different claims. Age is a number and there is nothing to argue about. Condition is an assessment, and an assessment can be documented — which is the only one of the two a roofer can help you with.
Your insurer and your broker are the right people to talk to about what the notice means and what your options are. Ours is the narrower job described below: putting the actual condition of your roof on paper.
Wood Roofs Draw the Hardest Line
If your home has a cedar shake or shingle roof, this is a materially harder problem than an aging composition roof. The Department of Insurance’s Safer from Wildfires materials identify asphalt shingle, concrete and clay tile, and metal shingles or panels as Class A fire-rated coverings, and wood shake is not among them. California Building Code Chapter 7A requires a Class A roof assembly in designated Wildland-Urban Interface areas and Very High Fire Hazard Severity Zones, and fire-retardant-treated wood shingles and shakes have to be approved and listed by the Office of the State Fire Marshal to be used at all.
Even where a treated wood assembly does carry a Class A rating, our experience across Los Gatos, Saratoga, Los Altos Hills, and the hillside neighborhoods above Highway 9 is that carriers decline it anyway. The rating is not what they are underwriting. The material is.
Discoloration makes it worse, and this is where the process stops being technical. An adjuster once pointed at the greenish cast on the north slope of a cedar roof on one of our jobs and called it mold. That cast is algae and weathering patina — cedar’s natural oils make it decay-resistant, and that slope was doing its job — but the word in the report was mold, and the report is what the underwriter read. Flat roofs with any discoloration get flagged the same way.
What a Roofing Contractor’s Letter Can and Cannot Do
Los Gatos Roofing has written condition letters for homeowners in this exact position. A condition letter documents what a contractor found on the roof — the covering, the flashings, the fasteners, the details — and states a professional opinion on remaining useful life and whether the roof is keeping water out. It is evidence, and it is more than an underwriter usually has.
Sometimes a carrier accepts it. Sometimes the same letter, on the same roof, goes nowhere with a different carrier. Acceptance is entirely the insurer’s decision, and no contractor can promise you an outcome — anyone who does is selling you something. What the letter reliably gives you is a documented, dated, third-party assessment to attach to an appeal or to hand to the next carrier’s underwriter.
Pair it with the rest of the file. Permit records establishing the install date, photographs, prior repair invoices, and documentation of any completed wildfire mitigation work all help. Under the Department’s Safer from Wildfires regulation, insurers must offer discounts for listed mitigation actions, including a Class A fire-rated roof, and proof of completion is what triggers them.
Where a Roofer’s Job Ends
There is a whole conversation about coverage options that follows a non-renewal, and it is not ours to have. Your broker knows the admitted market, the surplus lines market, and the FAIR Plan, and knows which of them fits your house and your mortgage. We are not licensed to advise on any of it, and we will not pretend otherwise.
What we can tell you is whether the roof is keeping water out, how much life is left in it, and what it would take to make it a Class A assembly. That is a real input to the coverage conversation, and it is worth having in hand before you start it.
Roofs That Had No Business Coming Off
Some of the tear-offs we have done over the past few years should not have happened. The roof was sound, the details were tight, it was keeping water out, and it came off because a policy was going to lapse and the homeowner had a mortgage that required coverage. That is a bad situation, and pretending otherwise would not serve anyone.
It also cuts the other way. Never put replacement money into a roof that has genuinely expired, and never let a carrier’s silence convince you a failing roof is fine. If you are unsure which side of that line you are on, a walked inspection — not a satellite image, not a drive-by — is the only thing that answers it honestly. Our approach is laid out on our roof replacement page.
What This Means for Your Next Roofing Material
Here is the part that gets skipped in every solar-and-shingle sales conversation in the South Bay: if your lender requires you to carry fire insurance, your roofing material choice has insurance consequences years down the road. That is a decision you make once and live with through three or four policy renewals.
Los Gatos Roofing will still install a wood roof for a homeowner who wants one. The disclaimer comes first rather than afterward — insurers do not like them, and a beautiful cedar roof installed today may be the reason a carrier walks in 2034. Homeowners who want that look without that exposure usually land on either a Class A composition system, tile, standing seam metal, or one of the synthetic composite shake products, each of which carries its own trade-offs worth understanding before you commit.
If a non-renewal notice just landed, the useful first step is finding out what your roof is actually worth in remaining years, from someone who will tell you when the answer is “more than you think.” Confirming the coverage specifics with your agent or the California Department of Insurance at insurance.ca.gov is the other half of that same afternoon.
