Coastal and catastrophe property insurance: wind, named storm, hail, and flood
Capacity for the hard-to-place risk: coastal wind, named storm, hail belt, flood, and quake.
By Dan Wentz, commercial real estate insurance broker · Updated
Catastrophe-exposed property is where the standard market still says no.
Near the Gulf, most standard carriers won't write windstorm at all, so the coverage moves to E&S and London markets and named-storm deductibles start around 5% of insured value. On a $20M building, that's the first $1 million out of your pocket before the carrier pays a dime. Placing this well takes real market access and a willingness to build the program in layers: find the capacity, engineer the deductible, keep the limit adequate and the lender satisfied.

Coverage
What we structure
Wind & named storm
Primary and excess wind, including named-storm placements through E&S and London markets.
Hail, wildfire & quake
Specialty capacity for hail-belt, wildfire, and earthquake-exposed locations that standard markets have sublimited or declined.
Deductible engineering
Percentage-deductible buy-downs and structures that keep one storm from wrecking a year of cash flow.
Parametric & captive options
Alternative risk transfer for when traditional capacity is scarce or priced past the point of sense.
Surplus lines insurers are not licensed (“admitted”) in Alabama, and policies they issue are not protected by the Alabama Insurance Guaranty Association if the insurer becomes insolvent. Surplus lines placements are generally made only after admitted markets have been considered, as state law requires.
Who writes coastal wind for commercial property?
Three kinds of capacity write it: E&S carriers, London market underwriters, and state wind pools. Standard carriers write little wind near the water, so most coastal commercial property ends up with one of the three, or with a layered mix of them.
The state pools exist for owners who cannot get wind coverage in the regular market. Each pool sets its own eligibility, limits, and territory, so confirm them with the pool before you plan around one. These are the pools we see most often on the Gulf Coast:
- Alabama Insurance Underwriting Association (Alabama). Known as the Beach Pool. It writes wind and hail only policies for property south of the 31st parallel in Baldwin and Mobile counties, per the Alabama Department of Insurance. Official site: aiua.org.
- Citizens Property Insurance Corporation (Florida). Florida's insurer of last resort, with commercial policies in addition to personal lines. Eligibility and coverage terms are set by Citizens. Official site: citizensfla.com.
- Texas Windstorm Insurance Association (Texas). Offers wind coverage to home and commercial property owners who cannot get it in the regular market. Official site: twia.org.
- Mississippi Windstorm Underwriting Association (Mississippi). A residual market for windstorm and hail on the Mississippi Gulf Coast, for personal and commercial property, according to its plan of operation. Plan documents: msplans.com.
- Louisiana Citizens (Louisiana). The state's Citizens Property Insurance Corporation, which offers commercial lines alongside personal lines. Eligibility and limits are set by Citizens. Official site: lacitizens.com.
Older coastal buildings: what underwriters want to see
A building from the 1980s or earlier gets priced on what the underwriter cannot see. The submission has to show it. For older coastal property, these are the items that move a quote or decide whether there is one:
- Roof age and roof cover. Year installed, material, and any re-roof or repair records. Roof condition is one of the first things an underwriter checks on a coastal building.
- Openings protection. Impact-rated glazing, shutters, and how doors and windows are protected. Wind that breaches an opening lets water into the building, and that can turn a roof claim into an interior one.
- Wind mitigation or FORTIFIED. A wind mitigation report or a FORTIFIED designation is documented evidence of wind resistance. Whether it earns a credit is the carrier's call, so ask in writing before you budget for one.
- An updated valuation. A current replacement cost value matters twice on the coast. A stale value understates the rebuild cost, and a percentage deductible applied to it understates what you will retain.
- Loss runs and maintenance records. Five years of loss history, plus inspection and maintenance records for roofs, drainage, and building envelope.
How do layers and a deductible buy-down work on $40M of coastal property?
Large coastal limits are rarely bought from one carrier. The program is built in layers, with a primary layer and one or more excess layers, so no single carrier's appetite caps the limit. The named storm deductible then sits on top as a percentage of insured value.
Here is the arithmetic on a hypothetical $40 million property. The numbers are illustrative, not a quote, and the cost of the buy-down depends on the market.
| Item | Amount |
|---|---|
| Total insured value | $40,000,000 |
| Limit structure | $10,000,000 primary + $30,000,000 excess |
| Named storm deductible at 5% | $2,000,000 |
| Named storm deductible after a buy-down to 2% | $800,000 |
| Retention the buy-down removes | $1,200,000 |
Coastal coverage your lender will accept
Lenders set their own limits on named storm deductibles, windstorm sublimits, and carrier ratings, and a cheap program that fails the loan documents will not close. Fannie Mae and Freddie Mac apply a cap on multifamily named storm deductibles, covered in our named storm deductible guide.
Check the loan documents before you pick a deductible. If you are a loan officer reviewing a coastal borrower's program, send it to us and we will flag deficiencies before closing. To size what a deductible leaves the borrower holding, use the wind deductible calculator.

FAQ
Common questions
Which markets write wind on older coastal apartment buildings?
Usually E&S and London market underwriters, sometimes with a state wind pool for the primary layer where the property is eligible. Roof age, openings protection, and a current valuation decide how many of them will quote. The submission has to show those three things clearly, and the layers are built so that one carrier's appetite does not cap the limit.
My coastal property is hard to insure. Can you place it?
Usually, yes. CAT-exposed property is rarely uninsurable. It just has to go to surplus-lines and London markets, often in layers, and it has to be presented by someone those markets know. We assemble the capacity and structure the deductibles so the limit is adequate and the cost is survivable.
Can you reduce my wind/hail deductible?
Often. Deductible buy-downs and program restructuring can both move it. We model the trade-off between premium saved and risk retained so you can see what the structure does to your balance sheet before you commit.
Do you use parametric or captive solutions?
When they make sense, which is not always. Parametric covers and captives can be the cheapest way to finance catastrophe risk in a distressed market, and a waste of money outside one. We'll show you the math either way.
Coverage described on this page is a general summary, not a quote, coverage recommendation, or offer of insurance. Requesting a quote doesn't bind coverage. Terms, exclusions, and availability vary by carrier, state, and property, and only the policy actually issued determines coverage. Insurance is placed through producers licensed in the state where the property is located.
