Major carriers have paused or restricted new homeowner policies in California in recent years, and the ones still writing are underwriting harder — with the roof at the top of the checklist. That shows up for homeowners three ways.
The three ways roof rules bite
| The rule | What it means for you |
|---|---|
| Age cutoffs | Many carriers won't write a new policy on a roof older than 15–20 years — a problem when you're shopping for coverage after a non-renewal, or selling the house and the buyer can't get insured. |
| ACV schedules | Some policies switch roof claims from replacement cost to actual cash value (depreciated value) once the roof passes an age threshold — in some policies as young as 10 years. A hail or wind claim on an old roof can pay out a fraction of what replacement costs. |
| Inspection non-renewals | Carriers increasingly use aerial imagery to screen roofs. Visible wear — curling shingles, patching, moss — can trigger a "replace it or lose coverage" letter with a short deadline. |
The FAIR Plan's 25-year rule — and the way off
For homeowners already pushed onto the California FAIR Plan — the state's insurer of last resort — the roof rule is written into the policy itself: replacement-cost coverage is automatic only for homes 25 years old or less. If your home is older than 25 years, the roof must have been replaced within the last 25 years — otherwise the FAIR Plan pays roof claims at depreciated actual cash value only.
The other half of the story is the good half: the voluntary market is reopening. Mercury and CSAA received the state's first sustainable-insurance rate approvals in 2026 — with Mercury committing to tens of thousands of new California policies and CSAA specifically taking on FAIR Plan customers — and Travelers announced a California homeowners expansion in April 2026. Brokers report the retrofits that most consistently move a home off the FAIR Plan and back to a normal carrier are a Class A fire-rated roof, documented defensible space, and exterior hardening.
What to actually do — in order
- Find your roof's age. Permit records, the disclosure package from when you bought, or an inspection report. If you genuinely can't establish it, insurers will assume it's old.
- Read the roof section of your policy — look for "actual cash value," "roof payment schedule," or "roof surfaces endorsement." If it's there, you already know how a claim will be paid.
- Keep proof for a newer roof. Receipts, the permit, and the contractor's completion letter are what win appeals when an automated screen misjudges your roof's age.
- If you're past 15 years: get the roof professionally evaluated before your renewal date. Sometimes a repair and certification keeps a carrier happy. Sometimes replacement is the answer — and doing it on your schedule, with a contractor you chose, beats doing it in a 30-day non-renewal window with whoever's available.
The San Diego math
A full roof replacement in San Diego typically runs from around $9,000 for a modest asphalt roof to $30,000+ for tile or larger homes — the ranges are broken down in our San Diego roofing cost guide. Set against that: an ACV claim payout on a 20-year-old roof can be cut by half or more through depreciation, and losing coverage entirely forces you into the FAIR Plan or surplus lines at materially higher premiums. For a roof at the age cutoff, replacement is increasingly less a maintenance decision than an insurance one.
Insurance practices vary by carrier and change frequently; this page describes patterns in industry reporting as of August 2026, not your policy. Read your own renewal documents, and talk to your agent about how your carrier treats roof age — then decide with real numbers.
