Wood Shake Roof Insurance Non-Renewal in California: Your Options

The letter usually arrives without warning. Your insurance company is not renewing your homeowners policy, and the reason is your wood shake roof. If you just got one of these letters, you are not alone — carriers across California have been dropping homes with wood roofs for several years now. The good news: you have time, and you have options.

I'm Brian Espindola. I run NuShake Roofing out of Ripon under my own C-39 license, CSLB #1142280. We've been roofing California homes since 1976, and we've watched shake go from the standard choice to an underwriting red flag. This guide walks through what the letter means, the timeline you're on, and each option — honestly, including the costs.

Why Carriers Are Dropping Wood Shake Roofs

Two reasons show up in almost every one of these letters: fire and age.

Fire risk. Untreated wood shake is exactly what it sounds like — thin pieces of dry wood covering your house. In a wildfire, the biggest threat to most homes is not the flame front. It's embers, which can travel far ahead of a fire and land on roofs. A wood roof gives those embers fuel. After years of heavy wildfire losses, California carriers rewrote their underwriting rules (the criteria they use to decide which homes to insure), and wood roofs were among the first things screened out.

Age. Most shake roofs in California were installed decades ago, when shake was the default for new homes. Wood roofs also wear out faster than most modern materials. So carriers often see two problems on one roof: a combustible material and a roof near or past the end of its service life. Either one can trigger a non-renewal. Together, they make it close to automatic.

One thing worth hearing plainly: the non-renewal is about the roof, not about you. Your payment history and claims record usually have nothing to do with it.

What the Letter Means — and How Much Time You Have

First, the difference that matters most. A cancellation ends coverage mid-term, which California law only allows in narrow cases. A non-renewal means the carrier will not offer you a new policy when the current one expires (the policy simply ends at its renewal date). You are still covered until that date.

California law also requires the carrier to mail the non-renewal notice well in advance — at least 75 days before the policy expires, per the California Department of Insurance. That notice window is your planning runway. Here's how to use it:

• Read the stated reason. The letter must tell you why. If it names the roof, you know exactly what has to change.
• Call your agent and ask one question in writing: "If I replace the roof with a Class A assembly before the expiration date, will you reconsider?" Some carriers will. Getting the answer in writing protects you either way.
• Get roof inspections and written quotes early. Roofing schedules fill up, and you want the option of finishing the new roof inside the notice window.
• Line up a fallback. If the roof can't be done before the expiration date, you'll need bridge coverage — more on the FAIR Plan below. Never let coverage lapse, especially if you have a mortgage; your lender can force-place insurance that costs more and protects only the lender.

Your Options, Ranked Honestly

Option 1: Replace the Shake with a Class A Roof — the Real Fix

This is the option that actually solves the problem instead of working around it. A full shake roof conversion removes the combustible material and the aging roof in one project, which removes the reason on your non-renewal letter. With a documented Class A roof, you're not begging your old carrier to take you back — you're a home the standard market wants again.

It also fixes things the insurance letter doesn't mention. An old shake roof near the end of its life is a leak risk and a resale problem. Buyers' insurance quotes hit the same wall yours did, so an uninsurable roof can stall a sale. A new Class A roof clears all of it at once.

What "Class A" Means in Plain English

Class A is the highest fire rating a roof covering can earn. To get it, a roof assembly has to pass standardized burn tests (severe flame and burning-ember exposure on a test deck). In practice, the common Class A choices are:

• Asphalt fiberglass shingles — the most common conversion choice, and the most budget-friendly.
• Standing-seam or stone-coated metal — lighter weight, long service life.
• Concrete or clay tile — durable, but heavy enough that the structure may need checking first.

One detail specific to shake conversions: most shake roofs sit on spaced boards (gaps between the roof planks, which let the old wood breathe). Modern Class A roofs need solid decking underneath. So a proper conversion includes tearing off the shakes and installing new plywood decking before the new roof goes on. That step is part of why conversions price toward the higher end — and skipping it is the kind of shortcut that causes problems later. If you live in a designated wildfire zone, our WUI fire roofing guide covers the extra rules that may apply.

Option 2: Shop the Standard Market Before You Decide Anything

It costs nothing to have an independent insurance broker (one who can quote many carriers, not just one) shop your home. Be honest about the odds, though: with the shake still on the roof, most standard carriers will decline for the same reason your current one did. Where this step earns its place is timing — a broker can tell you which carriers would write the home after a roof replacement, so the new roof and the new policy land together.

Option 3: Fire-Retardant Treatments — Mostly a Dead End

You may see companies offering to spray or treat your existing shakes with fire retardant. Honest assessment: treatments weather away over time, they don't fix the age of the roof, and carriers very rarely reverse a non-renewal because of one. If a treatment company tells you it will satisfy your insurer, get that insurer's confirmation in writing before you spend a dollar. We don't sell treatments, and we'd say the same thing if we did — the underwriting math doesn't change.

Option 4: The FAIR Plan — the Fallback, Not the Goal

The California FAIR Plan is the state's insurer of last resort (a shared pool all carriers fund, for homes that can't get standard coverage). It will usually write a home with a shake roof. But know what you're buying:

• It covers less. The FAIR Plan is a basic fire policy. It does not include things a normal homeowners policy covers, like personal liability or water damage from burst pipes.
• It usually costs more in total. To fill the gaps, most homeowners add a second wrap-around policy (often called a DIC, or "difference in conditions," policy). FAIR Plan plus DIC typically costs more than the standard policy you lost.
• It has coverage caps. Higher-value homes can bump into the FAIR Plan's dwelling limits.

Used right, the FAIR Plan is a bridge: it keeps you legally covered while the new roof gets built, and then you return to the standard market. Used as a permanent home, it's the most expensive way to keep an uninsurable roof.

The Cost Conversation, Honestly

A full roof replacement runs about $13,000–$24,000 for most Central Valley homes and $14,000–$32,000 for most Bay Area homes. Shake conversions tend to land toward the higher end of those ranges, for reasons you can now see coming: full tear-off and disposal of the old shakes, plus new solid decking over the spaced boards before the Class A roof goes on.

That's real money, so weigh it against the alternative. Staying on a shake roof usually means years of FAIR-Plan-plus-DIC premiums above what standard coverage costs, a roof that still has to be replaced eventually, and a harder sale if you ever list the home. The conversion is the only option on this list that ends the problem instead of renting a delay. If paying for it up front is the obstacle, we offer financing through Service Finance — our roof financing guide compares the payment options.

How to Document the New Roof for Your Carrier

The roof only solves your insurance problem if the insurer can verify it. When the job is done, build a simple proof package:

1. The final permit sign-off from your city or county building department.
2. The contractor's itemized invoice showing the licensed contractor's CSLB number and naming the Class A roof assembly installed.
3. The manufacturer's spec sheet for the installed product, showing its Class A fire rating.
4. Photos — before, during (the new decking matters), and after.
5. The warranty registration. As a GAF Master Elite and CertainTeed Select ShingleMaster contractor, we can register enhanced manufacturer warranties like GAF Golden Pledge or CertainTeed SureStart Plus — paperwork that also signals a verified installer to your carrier.

Send the package to your agent or broker and ask them to re-shop the home. Also ask about wildfire mitigation discounts — California's "Safer from Wildfires" framework requires many carriers to recognize hardening steps like a Class A roof in their pricing. And keep copies forever; you'll want them at every renewal and when you sell. If your roof has actual storm or fire damage right now, that's a different path — see our California roof insurance claim guide.
