What Is a Windstorm Mitigation Discount?
A lower premium for home features that resist wind damage, like a reinforced roof or storm shutters, confirmed by an inspection.

Whether this applies to you depends on how the house was built and where it sits. A wind mitigation inspection looks at the roof shape, the roof-to-wall connections, the age of the roof, and features like impact-resistant windows or storm shutters. If the house has them, the inspection report goes to the insurer and can lower what you pay. Some sellers already have a current report, which saves you the cost of ordering one. Ask the seller or your agent before closing, since an older inspection may not count.
Don't buy coverage before checking what the house already earns
If this house qualifies for a wind mitigation discount, one insurer's price could drop a lot more than another's. Comparing quotes before closing shows which ones actually give you credit for it.
How to get the inspection done and what it costs
A wind mitigation inspection is a separate visit from the general home inspection most buyers already schedule. A licensed inspector checks the roof covering, the roof deck attachment, the roof-to-wall connections, and whether the house has a secondary water barrier or opening protection like shutters or impact windows. Each feature gets recorded on a standard state form, not a narrative report, so the insurer can read it quickly and apply whatever credit each feature earns.
The cost usually runs somewhere between seventy five and two hundred dollars, paid out of pocket since it is not part of a standard closing cost package. It is worth asking the seller if one was done recently, because many states set a validity period, often five years, after which the insurer will want a new one regardless of what the old report says. If the house is newer, the original permit and construction documents can sometimes substitute for parts of the inspection, since code requirements at the time of building already establish things like roof-to-wall connections.
Timing matters more than people expect. If the inspection happens after the insurer has already issued a quote, getting the discount applied can mean a revised quote or an endorsement added after the policy starts, which creates a gap between what you were quoted and what you actually pay at binding. Scheduling the inspection early enough that the report is in hand before you request quotes means every insurer is pricing the same house, not a guess at what it might qualify for.
Not every feature on the form has to be present for a discount to apply. Credits are often layered, so a house with a hip roof and newer roof-to-wall connections but no shutters can still see a meaningful reduction, just not the full amount a fully hardened house would get. The report itself lists which credits were verified, and that's the document worth keeping with the policy paperwork, since a future insurer at renewal time or a future buyer at resale will likely ask for it again.
What the inspection form actually changes on your quote
The wind mitigation form isn't a pass or fail. Each line item on it, roof shape, roof deck attachment, roof-to-wall connections, opening protection, is priced separately by the insurer. A hip roof might knock a percentage off on its own. Clips or straps at the roof-to-wall connection are worth something different, and shutters or impact windows are their own line. When a quote reflects the inspection, ask to see how it broke down the credits. That's the only way to know whether the number is using the full report or just part of it.
Two insurers can land on different prices for the same house with the same inspection report. Insurers aren't required to credit every feature the same way, and some weigh roof age or the specific type of roof-to-wall connection more heavily than others. A house with toe nails instead of clips might barely move the needle with one insurer and matter a lot to another. The report is the same piece of paper either way. What changes is how each insurer's pricing model reads it.
Before closing, it helps to get the report into the hands of whoever is preparing your quotes rather than mentioning it after the fact. An insurer pricing a house without the report will often default to the least favorable assumption, since there's no documentation saying otherwise. Sending the form up front means the quote already reflects whatever the house earns. The number compared at closing ends up being the real one, not a placeholder that gets adjusted after the policy is already in place.
If the house doesn't qualify for much, that's useful information too. Some older homes have features that genuinely won't earn a discount no matter which insurer prices them, and no amount of paperwork changes that. The report still has value in that case, because it rules out guessing. It lets quotes be compared knowing the dwelling coverage and premium differences come from something other than wind credits.
Before you request quotes
Check whether the seller has a current wind mitigation report, and if not, find out how soon one can be scheduled. Having it in hand before quotes go out is what lets insurers price the house correctly the first time.
