If your homeowner's insurance bill has gone up in the last few years, you're not imagining it. Florida's insurance market has been in significant upheaval — private carriers have pulled back from coastal counties, Citizens Insurance has tightened its requirements, and premiums across the Treasure Coast have climbed for many homeowners regardless of whether they've ever filed a claim.
What a lot of homeowners don't realize is that their roof is one of the biggest factors driving that number — and that a new roof is often one of the most effective ways to bring it back down.
This isn't a sales pitch. It's how Florida's insurance system actually works, and it's worth understanding before your next renewal comes around.
Why Your Roof Affects Your Insurance Premium
In most parts of the country, your roof is one factor among many when an insurer calculates your premium. In Florida — and specifically on the Treasure Coast, where hurricane exposure is real and year-round — it's often the single biggest one.
Florida's insurers are looking at two things when they assess your roof: how old it is, and how well it was built to withstand wind. An older roof built before modern Florida Building Code wind standards typically means higher risk in the insurer's model, which typically means a higher premium. A newer roof built to current standards, with features that the state formally recognizes as hurricane-resistant, can work in your favor at renewal time.
“Many private insurers now impose limits of 15 to 20 years for asphalt shingle roofs,” and some have tightened further. “Citizens Property Insurance generally requires shingle roofs to be under 25 years old, and tile, metal, or concrete roofs to be under 50 years old.” “Roofs older than those thresholds require documentation showing at least five years of remaining useful life before Citizens will write or renew a policy.”
For homeowners in Stuart, Port St. Lucie,Jensen Beach, Palm City, and the surrounding area — where a significant portion of the housing stock was built in the 1970s, 1980s, and 1990s — this is not an abstract concern. If your roof is approaching or past that threshold, your insurer is paying close attention. In many cases, a new roof doesn't just lower your premium. It keeps you insurable.
The Wind Mitigation Inspection — What It Is and Why It Matters
Here's where it gets specific — and where many Treasure Coast homeowners leave money on the table.
Florida has a formal programme called the wind mitigation inspection. It's a state-standardised evaluation of your home's hurricane-resistant features, documented on a form called the OIR-B1-1802. Once completed by a licensed inspector, that form is submitted to your insurance carrier.
“Florida Statute 627.0629(1) requires every property insurer in the state to discount the windstorm portion of your premium based on what the inspection finds.” That's not optional for the carrier — it's the law.
The OIR-B1-1802 was updated effective April 1, 2026, based on a state-commissioned wind-loss study, so if your inspection report predates that, it may be worth scheduling a new one to see if your credits have changed.
What does the inspection actually look at? The main features that typically qualify for meaningful credits are:
Roof shape. A hip roof — where all four sides slope down to the walls — generally performs better in high winds than a gable roof. Insurers typically recognize this with a credit under the wind mitigation programme.
Roof deck attachment. How the roof deck is nailed to the structure beneath it matters significantly in a storm. Ring-shank nails and closer nail spacing typically score better than smooth-shank nails at wider spacing — which was common before the 2001 Florida Building Code updates.
Secondary water resistance. A self-adhering underlayment beneath the roofing material — commonly called peel-and-stick — provides a secondary barrier if the primary roofing is damaged in a storm. Homes built before this was standard often don't have it.
Roof-to-wall connections. How the roof connects to the walls of the house is one of the most structurally significant factors in a high-wind event. Hurricane straps and clips, properly installed, typically earn meaningful credits.
Roof covering. The age and type of material matters. A newer roof installed to current Florida Building Code standards is generally rated to handle higher wind speeds than an older one.
A new roof built to current code typically improves several of these categories at once — which is why the inspection and the replacement are often connected. When Oak & Anchor installs a new roof, we document the installation in the way that makes the subsequent wind mitigation inspection as clear and well-supported as possible.
What the Savings Can Look Like
We want to be careful here — insurance savings vary significantly based on your carrier, your coverage amount, your location, and exactly which features your home qualifies for. We can't tell you what your premium will be after a new roof and wind mitigation inspection, and anyone who gives you a specific number without seeing your policy and your home is guessing.
What we can tell you is what Treasure Coast homeowners commonly experience.
A wind mitigation inspection can save Florida homeowners anywhere from $100 to more than $1,000 per year, depending on the home's wind-resistant features, insurance carrier, and location. For coastal areas like Martin and St. Lucie County where base premiums tend to be higher, homeowners often find themselves at the higher end of that range. The inspection itself is valid for five years — so the cost is typically recovered in a matter of months, and the savings compound over the life of the report.
The picture changes even further when you factor in the broader insurance relationship. A new roof — particularly one installed to current code with documented features — can often open doors to better policy terms, additional carrier options, and in some cases renewal eligibility that wasn't available with the old roof. That's harder to put a number on, but for homeowners approaching the insurer's age thresholds, it can be significant.
Citizens Insurance and the Treasure Coast Specifically
It's worth addressing Citizens Insurance directly, because it affects a lot of Treasure Coast homeowners - The following are taken from https://www.citizensfla.com/inspections
“A significant portion of homeowners in Port St. Lucie carry policies through Citizens Property Insurance, the state-backed insurer of last resort. Citizens has specific rules around roof age and condition that affect both coverage and renewal eligibility.”
“Citizens requires a four-point inspection for all property applications on homes more than 20 years old, covering the electrical system, plumbing, HVAC, and roof.”
If your roof doesn't pass that inspection, or if it falls outside Citizens' age requirements, your options for coverage narrow quickly.
The good news is that a new roof resolves most of these issues cleanly. It resets the age clock, satisfies the condition requirements, and positions your home favourably for both Citizens and the private carrier market if you're looking to move off Citizens in the future.
What to Do Next
If your roof is more than 15 years old — or if your insurer has flagged it at renewal — it's worth getting a professional inspection before your next renewal date rather than waiting for a problem.
At Oak & Anchor Roofing, we're happy to take a look at your roof, give you an honest assessment of its condition, and talk through what a replacement might mean for your insurance situation. We're not insurance agents and we can't predict what your carrier will do — but we can tell you exactly what we're seeing on your roof and what a replacement would involve.
If we think your roof has meaningful life left and a repair makes more sense, we'll tell you that too. That's just how we work.
