The Buyer's Guide to South Florida Home Inspections: Wind Mitigation, 4-Point, and Roof Life

Buying a home almost anywhere means ordering a general home inspection. Buying a home in South Florida means ordering that, plus two or three Florida-specific insurance inspections most buyers relocating from out of state have never heard of. These aren't optional extras — for many South Florida properties, they determine whether you can get homeowners insurance at all, and at what price. Here's what each inspection actually checks, what it costs, and how they fit together.

The Three Inspections, in One Sentence Each

• 4-point inspection: Answers "can I get insured?" It's a limited review of four major systems — roof, electrical, plumbing, HVAC — and it's usually required by insurers once a home crosses a certain age threshold.
• Wind mitigation inspection: Answers "how big a discount can I get?" It documents hurricane-resistant construction features and can unlock meaningful premium credits.
• Roof condition/certification inspection: Answers "how much life does the roof have left?" Increasingly required as roofs age, and directly tied to Florida's roof-age insurance rules.

They overlap — all three look closely at the roof — but they serve different purposes and none replaces the others.

4-Point Inspection: The Insurability Gate

A 4-point inspection is a limited, visual review of a home's four major systems:

1. Roof — age, material, and general condition
2. Electrical — panel type, wiring type, and any outdated or hazardous components (knob-and-tube wiring, federal pacific panels, aluminum branch wiring, etc.)
3. Plumbing — pipe material and condition, watching for outdated materials like polybutylene
4. HVAC — age and functional condition of the heating and cooling system

Most Florida insurers require a 4-point inspection before writing a new policy or renewing an existing one on any home roughly 20 to 30 years old or older, though the exact threshold varies by carrier. This is not the same thing as a full home inspection — it's a narrower, insurance-focused report, and it does not replace the general inspection you should still order to evaluate the property for your own purchase decision.

Why it matters for buyers: if a 4-point inspection turns up a serious issue — an outdated electrical panel, aging galvanized plumbing, a roof near end of life — you may struggle to bind a policy at all, not just to get a good rate. This can directly affect your ability to close, since most lenders require proof of insurance before funding a mortgage.

Wind Mitigation Inspection: The Discount Multiplier

A wind mitigation inspection documents specific construction features that help a home resist hurricane-force wind, and the report can be submitted to your insurer for consideration of wind mitigation credits. Florida law requires insurance companies to offer premium credits for each documented hurricane-resistant feature present, though the final discount amount and eligibility are determined by the individual carrier, not guaranteed by the inspection itself.

The inspector evaluates several key categories, including:

• Roof covering type and installation date, and whether it meets current Florida Building Code standards
• Roof deck attachment — how the decking is fastened to the structure
• Roof-to-wall connections — the hardware (or lack of it) connecting the roof structure to the walls, one of the most heavily weighted factors
• Roof shape — hip roofs generally score better than gable roofs
• Opening protection — impact-rated windows, doors, garage doors, and skylights, or the presence of shutters

Homes built after 2002, under Florida's strengthened post-Hurricane Andrew building code, often qualify for meaningful credits by default. Older homes can still qualify if they've had qualifying upgrades — impact windows, a roof-to-wall retrofit, a new code-compliant roof — even if the rest of the structure predates modern code.

Realistic savings: reported figures vary by home and carrier, but many South Florida homeowners see somewhere in the range of 10% to 45% off the windstorm portion of their premium when strong qualifying features are present, with total policy savings commonly landing in the hundreds to low thousands of dollars annually. The inspection itself typically costs $75–$175, meaning it often pays for itself within the first year if it unlocks a meaningful discount.

Roof Certification and Florida's Roof-Age Insurance Rules

This is the inspection most likely to catch out-of-state buyers off guard, because it intersects directly with a legal protection — and a legal limit — unique to Florida.

The 15-year rule: Florida law prohibits insurers from refusing to issue or renew a homeowners policy solely because a roof is under 15 years old. Age alone isn't grounds for non-renewal in that window.

15 to 20+ years: Once a roof crosses roughly the 15-year mark, most carriers will require a roof condition certification or inspection before writing or renewing a policy. If the roof is 15 years or older, Florida law gives homeowners the right to a certified inspection — performed by a licensed roofing contractor, general contractor, home inspector, or engineer — establishing the roof's Remaining Useful Life (RUL). A report showing at least five years of remaining useful life can defeat an insurer's attempt to non-renew based on age alone, even past the 15-year mark.

Material matters a lot in South Florida's climate: standard asphalt shingles are typically rated for 15–20 years but often perform closer to 12–15 years under Florida's UV exposure and heat. Architectural shingles typically last 20–25 years. Metal roofs can last 40–70 years. If you're buying a home with an aging shingle roof, budget for the possibility that a carrier requires an inspection or shifts roof coverage from full replacement cost to actual cash value (which pays out a depreciated amount rather than full replacement cost on a future claim) — this changes your real financial exposure even if the roof passes.

For buyers specifically: request the seller's most recent roof certification or 4-point report, if one exists, before you're deep into your inspection period. If the roof is near a carrier's threshold, get your own insurance quote — not just a general estimate — before you're locked into the contract, since a roof that's technically insurable at 16 years might come with a materially higher premium than one at 8 years.

How These Interact With Your Inspection Period

None of these Florida-specific inspections are the same as the general home inspection covered under your purchase contract's inspection period, but they should happen on the same timeline. A few practical notes:

• Order 4-point and wind mitigation together when possible. Much of the information overlaps — especially roof details — and many inspectors offer a bundled rate for ordering both in the same visit, commonly landing around $180–$220 combined in South Florida.
• Get an insurance quote during your inspection period, not after. If you wait until after your cancellation deadline has passed to find out the home is difficult or expensive to insure, you may have already lost your unrestricted right to cancel. For a full breakdown of that deadline and what "As-Is" does and doesn't waive, see our guide to buyer inspection rights.
• A recent report can transfer or at least inform your quote. If the seller has a current wind mitigation or 4-point report, ask for it — carriers often accept a report that's within a few years old, which can save you the cost of a new inspection and give you an early read on your likely premium.
• Factor insurance into your total closing costs, not just your monthly payment. Insurance premiums and required escrow reserves are frequently the single biggest reason a buyer's cash-to-close number ends up higher than expected. Our guide to hidden closing costs in South Florida breaks down exactly where that money goes.

Frequently Asked Questions

Do I legally need a wind mitigation inspection to buy a home in Florida? No, it's not a legal requirement to purchase, but it's often financially worthwhile since it's the document that unlocks premium discounts. Some insurers may request one before finalizing your rate.

Is a 4-point inspection the same as a general home inspection? No. A 4-point inspection is a narrower, insurance-focused review of four systems (roof, electrical, plumbing, HVAC) and does not replace a full general home inspection, which is broader and covers the property for your own purchase decision, not just insurability.

My roof is 16 years old — can my insurer drop me automatically? Not solely for that reason, as long as you can produce a certified inspection showing at least five years of remaining useful life. Get that documentation proactively rather than waiting for a non-renewal notice.

Can I use the seller's existing wind mitigation or 4-point report instead of ordering my own? Often, yes — many insurers accept reports that are a few years old. Ask the seller for their most recent reports early in your inspection period; it can save you money and give you an early read on your insurance costs.

Does a good wind mitigation report guarantee a discount? No. The inspection documents features, but final eligibility and the actual discount amount are determined by your specific insurance carrier's underwriting guidelines, not by the report itself.

Insurance requirements, roof-age rules, and inspection costs vary by carrier and change as Florida's insurance market and legislation evolve. This guide reflects publicly reported 2026 standards; confirm current requirements with your insurance agent and a licensed inspector before making decisions based on a specific property.
