Homeowners in Florida, Louisiana, and coastal Texas are opening renewal notices this spring to find premiums that jumped 20% to 60% — or letters saying their coverage won't be renewed at all.
Insurers say the math no longer works after back-to-back years of billion-dollar storm losses.
Consumer advocates say something else is happening: companies are using climate risk as cover to exit markets they never liked.
Average US home insurance premiums climbed roughly 20% between 2022 and 2024, according to industry tracking, with some Gulf Coast zip codes seeing increases north of 50%.
In California, several major carriers paused new policies entirely, citing wildfire exposure.
In Iowa and Colorado, hail damage has pushed rates up double digits.
Here's the part that rarely makes the evening news.
When a big insurer pulls back, it doesn't vanish — it shrinks.
It stops writing new policies in risky areas but keeps collecting premiums from existing customers, who often have no realistic alternative.
That's a market where the exit door is locked from the inside.
State-backed insurers of last resort are absorbing the overflow.
Florida's Citizens Property Insurance became the state's largest carrier by default, and Louisiana's insurer of last resort has swelled past 100,000 policies.
These backstops were designed for catastrophes, not for everyday coverage.
If a major storm hits, the assessments to refill them can land on every policyholder in the state — including people nowhere near the coast.
So who actually benefits from the current mess?
Reinsurance companies, the global firms that insure the insurers, have posted strong results while raising prices.
Agents and brokers earn commissions regardless of which carrier writes the policy.
And the biggest winner might be the companies that stayed: they now face less competition and can charge more in the states they never left.
Shop your renewal at least 45 days before it lapses — carriers quote differently on the same house.
Raise your deductible if you can stomach the risk; moving from $1,000 to $5,000 can cut premiums meaningfully.
Ask about wind, hail, and flood exclusions, because standard policies almost never cover flooding, and that's a separate federal program most people don't carry.
Document your roof's age and condition, since many insurers now use aerial imagery to deny or price coverage.
Long-tenured customers are often the least likely to shop and the most likely to eat increases.
If your premium doubled, your neighbor with an identical house may be paying half — simply because they switched carriers last fall.
One more thing worth watching: some states are now allowing insurers to use "catastrophe models" that project future risk rather than past losses.
That sounds technical, but it means your rate can rise based on a storm that hasn't happened yet.
Regulators approved it quietly, and few homeowners know it's happening. **The takeaway:** Insurance is supposed to spread risk across a wide pool, not concentrate it on the people who can least afford to move.
Final Thoughts
If your premium is spiking, treat the renewal notice as a negotiation, not a verdict — and pressure your state insurance commissioner, because they're the only referee in this game.
