What retrofits actually lower a Florida insurance bill?

The order that matters

Every credit on the wind mitigation form is not worth the same amount of money or the same amount of disruption. This is the order I would spend in.

1. 1Roof-to-wall connections. Moving from toe-nails to clips, and from clips to straps, is a significant step each time.
2. 2Roof deck attachment. Nail size and spacing, or a re-nail carried out during a re-roof.
3. 3A secondary water barrier, also called a sealed roof deck.
4. 4Opening protection on every opening, the garage door included.
5. 5Roof shape. You cannot change it without rebuilding, but it is credited, so make sure the report records it correctly.

The cheapest real win

When you re-roof, pay for the deck re-nail and the sealed deck. Both are small additions to a job you are already paying for, the crew is already there, and both are credited for years afterwards. Skipping them to save a few hundred is the most common expensive decision I see on a roof contract.

Ask for them to be itemised on the quote so you can see what you are buying, and make sure the permit and the final inspection are in the contractor name.

Opening protection is all or nothing

Partial protection earns very little. The credit largely wants every opening protected, and the garage door is the biggest and weakest opening on most houses. Protecting the windows and leaving the garage door untouched is a common and expensive mistake.

Whether impact glass is worth it on its own is a different question: are impact windows worth the money.

Then go and collect the discount

None of this reduces a premium until it is documented. Get a wind mitigation inspection after the work is finished and hand the form to your agent. People leave this money on the table constantly — the work is done, the paperwork is not.

If you are not sure which report is which, start with the 4-point and wind mitigation explained.

What this looks like as a plan

Most houses do not need all of it at once, and the sensible version is to attach the work to jobs already happening rather than treating it as a separate project.

1. 1At the next re-roof: deck re-nail, secondary water barrier, and ask whether roof-to-wall connections can be improved while the deck is open.
2. 2At the next window replacement: current-code openings, and the garage door in the same phase rather than later.
3. 3Then order a wind mitigation inspection and hand the form to your agent.
4. 4Keep the closed permits. A carrier asking for proof two years later is routine.
