What Property Issues Make It Harder to Get Insurance or Raise Premiums?

Two inspection reports control your insurance fate in Florida: the four-point inspection and the wind mitigation report. The four-point determines whether a carrier will insure your home at all. The wind mitigation determines how much you pay. Together, they evaluate your roof, electrical system, plumbing, HVAC, hurricane protection, and how the structure holds together in high winds. Average Florida homeowners insurance runs $3,200 to $4,500 per year in 2026, and specific property issues can push that number far higher or disqualify you from coverage entirely.

The Four-Point Inspection Decides If You Can Get Covered

Most Florida carriers require a four-point inspection for homes 20 years or older before they will write a policy. The inspector evaluates four systems: roof, electrical, plumbing, and HVAC. If any of those systems have problems, the carrier can refuse coverage or place you on a higher-risk policy until you fix the issue.

On the Discover South Florida Podcast, Larry Mastropieri distilled the whole concept down to one line:

"The four-point dictates whether you can get insurance. The wind mitigation is going to determine your price. Those are the four points: roof, electrical, HVAC, and plumbing."

Problems with any of those four areas create real headaches during a transaction. Buyers touring homes in Boca Raton or Delray Beach need to think about insurability before they fall in love with the kitchen countertops.

Electrical Panels and Wiring That Carriers Reject

Certain electrical panels are blacklisted across the insurance industry. Federal Pacific Electric (FPE), Zinsco, and Sylvania panels all land on the "not so great list," as the podcast discussion put it. If your home has one of these, some carriers will refuse coverage outright. Others may accept the panel if a licensed electrician signs off on its condition, but you should plan for the possibility of a full panel replacement.

Wiring type matters just as much. Cloth wiring from homes built in the 1920s and 1930s, where copper conductors are wrapped in cotton rather than rubber, creates a serious fire risk. Carriers will not touch it. Aluminum wiring, common in homes from the late 1960s and early 1970s, requires special receptacles or a complete rewire depending on the carrier's appetite for risk. Inspectors sometimes confuse asbestos-wrapped wiring (which is actually fire-resistant) with true cloth wiring, so getting the distinction right saves you from unnecessary panic and unnecessary costs.

Roof Age and the 15-Year Tipping Point

Florida insurance carriers scrutinize roof age harder than almost anything else. A shingle roof past 15 years starts drawing attention. Past 20 years, most carriers demand replacement before they will renew or write a new policy.

Here is the part that catches buyers off guard: even when an inspector writes glowing remarks about the roof condition, carriers now review the photos independently. If the pictures show wear the inspector glossed over, the carrier rejects the application.

Larry Mastropieri has seen this play out firsthand:

"We've been turned down multiple times by insurance companies. Inspector says five years left of useful life on the roof, everything's great, check check check. And then the carriers look at the photos and say, 'We don't agree with that.' That's a new development in the past two years."

A single chipped ridge tile can trigger a denial too. Larry mentioned that he talks to a roofer about minor tile repairs roughly twice a week because carriers flag cosmetic damage that most homeowners would never notice.

How the Wind Mitigation Report Sets Your Premium

The wind mitigation inspection looks at how well your home can survive a hurricane. It checks roof shape, roof-to-wall connections, nail spacing on the roof deck, and whether every opening in the house has impact protection. Each category earns or loses you a discount. Together, those credits can swing your premium by 20% to 45% on the windstorm portion of the policy.

Roof Shape and What It Costs You

A hip roof, which slopes down on all four sides, gets the cheapest rate because wind flows over it without catching an edge. A gable roof costs more because the flat face acts like a sail in high winds. Flat roofs are the most expensive option unless they sit on a reinforced concrete deck, in which case they become the cheapest option of all. Wind cannot grab onto a concrete slab the way it grabs shingles or tiles.

Clips, Toenails, and Straps: The Hidden Cost Driver

How your roof connects to the walls of your house is one of the biggest factors on the wind mitigation report. Most buyers never think about it because you cannot see it from the ground. But the connection method determines whether your roof stays on during a Category 3 storm or peels off like a lid.

There are four levels. Toenails are the weakest, where the truss is simply nailed at an angle into the top of the wall. Clips use a metal bracket with nails on each side. Single wraps run a metal strap over the truss and down into the concrete block. Double wraps go even further. Each upgrade earns a bigger insurance discount, sometimes 10% to 15% off the annual policy.

Larry Mastropieri went through this exact process on his own buildings:

"We had toenails. Working with our insurance guy, we priced it out. We were going to get a 50% discount. So we said, okay, we're going to pay to retrofit to double wraps. They retrofitted it incorrectly with clips. They had to go back after the roofs were done, pull everything up again, and do the straps the way we paid them to."

His takeaway? You have to know your stuff, or you need people on your team who do. He kept his inspector, his insurance agent, his engineer, and his roofer all in the same email thread with photo documentation at every step. Without that level of oversight, the contractor's mistake would have cost him the full discount.

Hurricane Windows and the Easiest Discount Most Buyers Miss

Hurricane-rated opening protection is the single biggest discount available on most Florida policies. It can knock 40% to 50% off the windstorm portion of your premium. Yet plenty of homes throughout West Palm Beach and Boynton Beach still sit without any protection at all.

The good news? You do not need expensive impact windows to get the full credit. Aluminum storm panels from a home improvement store qualify for the exact same discount as $800-per-window impact glass. Shutters work too. The key is that every opening must be covered. Some carriers accept an "A3 rating," which means all glazed openings (windows and glass doors) are protected while solid doors without glass can remain as-is. However, most carriers want 100% coverage across every opening for the full credit.

If you are buying a house without hurricane protection, that upgrade should be the first thing on your list. It pays for itself through insurance savings faster than almost any other home improvement.

What Buyers and Sellers Should Do Before the Deal Closes

Insurance problems derail more South Florida transactions than most people realize. Delays in getting coverage are now one of the most common reasons closings get pushed back. Here is how to stay ahead of it:

• Order both the four-point and wind mitigation inspections early in the contract period, not at the last minute.
• Ask for the seller's existing inspection reports and insurance declarations page to spot red flags before you commit.
• Check the electrical panel brand and wiring type during your home tour, since FPE, Zinsco, and aluminum wiring create coverage problems.
• Look at the roof age and condition with your agent, because carriers now review photos independently of inspector opinions.
• Budget for hurricane shutters or panels if the home lacks opening protection, since that single upgrade unlocks the largest premium discount available.

Sellers benefit from getting ahead of these issues too. A pre-listing four-point inspection that comes back clean eliminates a major obstacle for buyers. Replacing a few chipped tiles before listing prevents a carrier rejection from killing a deal three weeks into the contract.
