April 1st brought a big deadline for homeowners in Southwest Florida: new rules for wind mitigation inspections and the credits insurers apply from those reports. The timing is inconvenient because many people have already done their assessments, locked in their discounts, and moved on. But for some homes, the updated underwriting approach could reduce credits or change what gets counted.
This matters because wind mitigation can directly affect insurance pricing, coverage eligibility, and how confidently buyers can shop for a policy. If a discount changes, it is not just a small adjustment. It can reshape what people can afford at renewal and influence buying decisions during transactions. In this blog, Mary Bartos with the Bartos Group of Premiere Plus Realty and Joe Nugent discuss these changes and what it means for homeowners and buyers in Southwest Florida.

First, what wind mitigation is (and why everyone cares)
Wind mitigation is a formal evaluation of building features that can help a home withstand hurricanes and high wind events. Inspectors look at items like roof characteristics, roof-to-wall connections, impact-resistant openings, and other construction elements.
Based on what is found, the report can earn the homeowner insurance credits. Those credits often translate into lower premiums. When rules change, the goal of an insurer is usually the same: more consistency in how credits are awarded, especially when underwriting teams feel some categories have been too easy to qualify for.
April 1 rule changes: what is shifting
Underwriters are cracking down on what homeowners can receive credits for. Some of the biggest adjustments focus on the details that get overlooked during normal maintenance or renovation projects.
Garage doors with windows: the “impact rated” problem
One example that keeps coming up involves garage doors that include small windows. In many cases, those windows are not impact rated. Under the updated underwriting approach, that can mean the credits tied to that garage opening may no longer apply.
In plain terms: if the insurer cannot verify impact-rated protection for those openings, the discount can be reduced or removed.
Spray foam insulation: changes that may help some homeowners
Not every update is bad news. The new approach also includes changes that can help homeowners who have spray foam insulation. Instead of insurers being unable to make certain assumptions, the updated rules may allow more flexibility in granting credits for qualifying installations.
So while some credits may be tightened, this is a good reminder that rule changes can cut both ways depending on what is actually installed in the home.
Flat roofs and hip roof calculations
Another change focuses on roof geometry. Underwriters are now including flat roofs in the total surface area when determining whether a roof counts as “hip” for the purpose of credits.
This can affect certain homes with areas like lanais or covered structures that are flat or partially flat. Even if a portion of the roof is hip, including the flat sections in the overall calculation can reduce how much of the roof qualifies toward the hip-related credit.
The big timing advice: get wind mitigation done soon
If the wind mitigation report is older and credits may change under the new underwriting rules, now is the time to act quickly.
The practical guidance is simple:
- If a wind mitigation report is not current, consider scheduling one!
- Plan for scheduling delays, because demand is likely to spike during high season.
- Coordinate timelines if home improvements are needed, since updates require time and documentation.
Underwriters are also rolling out updated procedures through training for home inspectors. That means the approval process may take more time as professionals adjust to the new requirements.
Insurance credits are often “all or nothing”
One of the most important takeaways from the current underwriting approach is that it is not always a sliding scale. Sometimes the difference between a full discount and zero credit comes down to a single component.
Consider impact-resistant openings. If a home has many impact-rated windows and doors, but one opening is not recognized as protected, underwriting may treat that specific feature as having no protection.
This is typically reflected in how the report is coded. As discussed by industry pros, if an insurer marks an element with an “X” style notation for no protection, it can lead to zero credit for that portion of the overall rating.
That is why it is worth reviewing not only the big renovations, but also the “small stuff”:
- transom windows
- small panes in doors
- garage openings and their associated components
- any protective coverings that were added later
What about transom windows and protective coverings?
Homeowners often assume that if a window is covered with something protective, the insurer will treat it as protected. The reality is more documentation-driven.
In many cases, the deciding factor is whether there is verifiable protection equivalent to what underwriting expects, such as a shutter system or proof that the covering meets the required standard.
So if transom windows were not replaced and were instead covered with plastic or a temporary solution, the outcome may not be favorable unless there is a way to demonstrate an accepted protective method.
Action item: gather any paperwork you have and be prepared to discuss what protection is currently installed and what can be documented as compliant.
Attic straps and truss clips: small details, big underwriting impact
Wind mitigation is not only about visible windows and roofs. It also includes roof-to-wall connection details, often assessed by looking at the attic.
Underwriters are also changing what they allow regarding components such as clips and straps used over the top of wood trusses. This is one reason the process can feel confusing for agents at the moment.
Training is happening across the state as the updated program rolls out, which means:
- inspectors may be learning the rules in real time
- agents may need time to fully understand what will and will not qualify
- homeowners could see inconsistent interpretations unless documentation is clear
The best defense is preparation: know what your home has, know what can be verified, and make sure your wind mitigation report reflects the real construction features accurately.

A homeowner game plan
Here is a sensible sequence that many homeowners can follow.
Step 1: Check the openings
- Verify whether every relevant window and door is impact rated.
- Pay extra attention to openings that are easy to forget, like garage door windows and transoms.
Step 2: Review roof features that include flat sections
- Identify any flat roof areas like lanais or covered extensions.
- Understand that insurers may treat those areas differently now in hip roof calculations.
Step 3: If repairs are needed, document everything
- Keep invoices, product specifications, and installation paperwork.
- Take photos before and after work is completed.
Step 4: Schedule a wind mitigation inspection with enough lead time
Even if an improvement is planned, a homeowner may still want the wind mitigation scheduled promptly so an inspector can confirm what exists today and what needs follow-up.
And yes, in some cases homeowners may choose to get an estimate first (for example, for a garage door) and then coordinate with the inspection so the final report reflects the updated situation.
Buyers and sellers: how this affects real estate decisions
Changes to wind mitigation can influence transactions because they can impact insurance cost assumptions and underwriting confidence. A discount that exists today could be different tomorrow, depending on how the new rules are applied.
For sellers, it can be worthwhile to confirm that the current wind mitigation report aligns with what insurers are counting under the updated approach. For buyers, it can reduce surprise costs to review wind-related underwriting items early in the process rather than after closing.
For real estate professionals, the key is education and proactive communication. The goal is not to scare anyone. It is to make sure expectations match the underwriting reality.
FAQ about wind mitigation changes
When do the wind mitigation changes take effect?
The updated underwriting approach is set to take effect April 1, bringing new rules for how credits are applied based on inspection results.
Should a homeowner get a new wind mitigation report if the current one is older?
If the report has not been done within about the last five years, scheduling sooner is a smart move, especially in the two weeks leading up to April 1, since rules and credit calculations may change.
Will garage door windows automatically qualify for impact-related credits?
Not necessarily. If the garage door windows are not impact rated, underwriters may reduce or remove credits for that opening.
Do flat roof areas affect hip roof credits?
Yes. Under the updated approach, flat roof portions can be included in the total roof surface area used to determine hip-related credit calculations.
If my windows are covered with plastic or temporary coverings, will that count as protection?
It depends on what protection is installed and whether it can be documented to meet underwriting expectations, such as approved shutters or verifiable systems.
What should homeowners do if they have attic straps or truss clips that they are unsure about?
Because underwriting allowances may change, homeowners should rely on inspection documentation and be ready to verify that the installed components meet current requirements.
Final takeaway: don’t let wind mitigation credits slip quietly
Wind mitigation is one of those topics where the details matter, and the deadlines matter even more. April 1 is close, insurers are tightening how credits are assigned, and even small unverified features can impact the final outcome.
The best next step is straightforward: check the features your report depends on and schedule updates quickly if the current wind mitigation information might not reflect what underwriting will count under the new rules.
