Florida Roof Rules Every Homeowner Should Know

In Florida, your roof isn't just maintenance — it's an insurance and building-code issue. These are the rules that decide whether you can keep your policy, how much repair you can do before code kicks in, and which inspections can lower your premium.

The 15-year roof rule (insurance)

Under Florida Statute 627.7011 (as amended by SB 4-D), an insurer cannot refuse to insure or renew a home solely because its roof is less than 15 years old. Once a roof passes 15 years, the insurer can require an inspection — but if that inspection shows the roof has at least 5 years of useful life remaining, the insurer cannot refuse coverage based on age alone.

• Roof under 15 years: age alone can't be used against you.
• Roof 15+ years: get an inspection documenting 5+ years of remaining life before renewal.
• This is why a roof inspection at renewal time is one of the most valuable documents a Florida homeowner can have.

The 25% rule (repairs)

Under the Florida Building Code, if more than 25% of a roof section is repaired, replaced, or recovered within a 12-month period, that section must be brought up to current code — not just patched to the old standard. (Roofs built under newer codes have some nuances here.)

• Small, localised repairs are unaffected.
• A large repair on an older roof can legally turn into a much bigger job — get the percentage assessed before work starts.
• When a repair approaches the 25% line on an ageing roof, full replacement is often the smarter spend. See roof replacement costs.

Wind mitigation inspection

A wind mitigation inspection documents how your roof resists hurricane winds — roof covering, deck attachment, roof-to-wall connections, opening protection, and more. Insurers must offer premium credits for verified wind-resistant features, so this inspection frequently pays for itself. It's one of the most-searched insurance topics in Florida for good reason.

4-point inspection

For older homes, insurers commonly require a 4-point inspection covering the four systems they care about: roof, electrical, plumbing, and HVAC. The roof portion records its age, material, condition, and any signs of leaks or damage. If you're selling or renewing on an older Florida home, expect this inspection — and expect the roof's condition to drive the outcome.

Coming December 31, 2026: Florida Building Code, 9th Edition

The next edition of the Florida Building Code takes effect December 31, 2026. Roofing work permitted after that date must meet the new edition's requirements. If you're planning a replacement, ask your contractor which code edition your permit will be pulled under — it can affect materials and installation details.

Hurricane season: June 1 – November 30

Florida's storm season drives the year's leak, tarp, and storm-damage repairs. Before the season: document your roof's condition with photos, know your hurricane deductible (it's usually a percentage of coverage, not a flat amount), and fix small leaks in spring — a $300 repair in April beats an emergency callout in September. If a storm damages your roof, a properly installed tarp is the standard first step; see leak repair costs for emergency pricing.
