What Recent Storms Taught Volusia County About Openings

Deltona is an inland city. It sits more than fifteen miles from the Atlantic, outside the coastal strip where the Florida Building Code automatically requires opening protection, and there is a fair argument that hurricane marketing here is oversold.

There is also a record. Volusia County has been on the receiving end twice in recent memory, and it is worth being specific about what happened rather than trading in vague dread.

The record

Nicole, November 2022. The storm did severe damage along Volusia’s coast, with dozens of coastal buildings collapsed or condemned as a result of beach erosion. Combined Volusia and Flagler County damage ran past half a billion dollars. It arrived roughly six weeks after Ian, while buildings damaged by that storm were still unsafe.

Milton, October 2024. Four deaths in Volusia County. Damage assessed at around $267 million across more than five thousand properties. More than a foot of rain in parts of the county in a day, and a gust of 92 mph recorded at the coast.

Neither of those is a Deltona-specific figure, and the worst of both was coastal. But a storm system that produces that much rain and that much wind at the coast is not a non-event twenty miles inland, and the tornado activity these systems spawn is not selective about elevation.

What damages a house

This is the part worth understanding, because it changes what protection is for.

The danger is not broken glass. It is what happens after an opening fails. Wind gets inside a sealed building, pressurizes it, and starts pushing outward on the roof and walls at the same moment the storm is pushing inward from outside. That combination is what takes roofs off.

Which means the goal is keeping the envelope closed, and the openings are the weak points in it. It also means the largest opening matters most: a house whose windows all hold but whose patio slider blows in has not been protected in any useful sense.

Two different requirements

The Florida Building Code asks two separate things of a window, and they get conflated constantly.

Design pressure applies statewide. Every exterior glazed opening has to be rated for the wind load calculated at its position on the building. That is true in Deltona, in Miami and in Tallahassee. It is a structural requirement about wind load.

Impact rating applies inside the wind-borne debris region only. That region is defined by the wind speed map: within one mile of the coastal mean high water line where the ultimate design wind speed reaches 130 mph, or anywhere it reaches 140 mph, for ordinary homes. Deltona is well outside the coastal trigger. Whether the higher contour reaches a particular parcel is a question for Volusia County’s published wind speed mapping and the city Building Division, and it is a fair question to ask directly.

So for most Deltona addresses, opening protection is elective. That is the honest position, and it is a better basis for a decision than a sales line about code requirements that may not apply.

Which makes it an insurance and judgment call

Elective does not mean pointless. Florida law requires insurers to reflect wind mitigation features in their rates, and opening protection is one of them, so the choice has a financial return that is written into statute rather than left to goodwill. The wind mitigation guide covers how that works.

And there is the availability argument, which the 2022 and 2024 seasons made concrete for a lot of people. Shutters protect a house when somebody is there to put them up. Impact glazing protects it whether or not anyone is home, whether or not the forecast changed at eleven at night, and whether or not the homeowner is in a position to be on a ladder. For a household that travels, or an owner who cannot safely deploy panels, that is not a marginal difference.

A proportionate response

If the windows are old and coming out anyway, price impact rating as an upgrade rather than a separate purchase, because the marginal number is much smaller than the sticker difference suggests. If the windows are newer and sound, shutters protect them for less. If money is tight, protect the biggest opening first.

And if the honest answer is that the house is inland, the windows are fine and the budget is better spent elsewhere, that is a legitimate answer too. The comparison guide lays out both routes, and a free measured quote will price them on your actual openings rather than on a hypothetical.
