HVHZ Roofing Code in Broward County, Explained

The core HVHZ requirements

A compliant Broward roof is built to a tougher standard than almost anywhere else in the country:

• Miami-Dade NOA-approved materials, tested to TAS protocols.
• Sealed roof deck with self-adhering ASTM D1970 underlayment.
• Re-nailing of the deck to current fastener schedules.
• A minimum of three inspections (vs. one or two elsewhere in Florida).
• An HVHZ Uniform Permit Application for every job.
• Enhanced fastening throughout — not just more nails, but specified patterns, lengths and edge distances at perimeters and corners where uplift is worst.
• Documented product approvals kept with the job, so the inspector can match what's on the roof to what was approved.

Where the HVHZ line falls on the map

The High-Velocity Hurricane Zone is not a general South Florida label — it is a specific designation that, in practice, covers Broward County and Miami-Dade County only. Coconut Creek, Margate, Coral Springs, Parkland, Pompano Beach, Deerfield Beach and Tamarac are all inside it.

Cross into Palm Beach County — Boca Raton, for instance — and you are outside the HVHZ. That does not mean the code goes soft: Palm Beach County sits in a wind-borne-debris region with substantial wind-load and opening-protection requirements under the Florida Building Code, and roofs there are permitted through the City of Boca Raton or Palm Beach County. But the specific HVHZ package — Miami-Dade NOA product approvals, the HVHZ Uniform Permit Application, the enhanced inspection count — is a Broward and Miami-Dade regime.

This is worth understanding if you own property on both sides of the line, or if you're comparing a roofer's Boca Raton work to their Broward work. The two jobs are permitted and inspected under different rules.

NOAs and TAS testing, decoded

A Notice of Acceptance is a product approval issued through Miami-Dade County's product control process. It says a specific product — a shingle, a tile, an underlayment, a fastener, a metal panel — was tested under the applicable Testing Application Standards (TAS) and performed to the level HVHZ requires, and it spells out how that product must be installed to keep the approval valid.

That last part is the part homeowners miss. An NOA is not a sticker on a box; it is an installation instruction with legal force. A tile installed with the wrong adhesive pattern, or a shingle fastened outside the approved nailing zone, is out of compliance even though the product itself is approved.

Practically, this means the whole assembly has to be approved together — underlayment, fasteners, starter course, field product, hip and ridge, flashing. Mixing an approved shingle with an unapproved underlayment breaks the assembly. Ask any roofer for the NOA numbers on the products they're proposing; a compliant contractor will have them ready.

The sealed deck — the upgrade that does the most work

If you take one thing from HVHZ, take this: the roof that saves your house in a hurricane is usually the layer you can't see. Post-storm damage assessments in Florida have repeatedly found that the catastrophic losses aren't the ones where a few tiles blew off — they're the ones where the covering came off and rain then poured straight through an unprotected deck for hours.

HVHZ addresses that with a sealed roof deck: the deck is re-nailed to current fastener schedules, then covered with a self-adhering ASTM D1970 underlayment that bonds to the sheathing and self-seals around fasteners. That membrane is the secondary water barrier. Even if wind strips the tile or shingle above it, the home underneath generally stays dry.

It also has an insurance dimension. Sealed-deck and secondary-water-barrier features are among the items a wind-mitigation inspection documents, and strong wind-mitigation results can lower a Florida homeowner's premium by roughly 10–40%. If you're replacing the roof anyway, make sure the wind-mitigation form gets completed afterward so the credits actually reach your policy.

Permits and the three inspections

Roofing work in Broward is permitted work — there is no legitimate version of a full re-roof done without one. In Coconut Creek, permits go through the City's Building Division at 4800 W Copans Rd via the ePermits portal; unincorporated areas and some neighboring municipalities permit through Broward County or their own building department.

HVHZ jobs require a minimum of three inspections, versus the one or two typical elsewhere in Florida. In broad terms they cover the deck and its fastening, the in-progress dry-in and tin-tag stage where the underlayment and its attachment are verified, and the final inspection of the completed roof. The exact sequence and naming vary by jurisdiction, so confirm the schedule with the building department that issued your permit.

Those inspections are also your protection. Each one is a third party confirming the roof was built the way the permit says. A roofer who wants to skip an inspection, or who asks you to pull an owner-builder permit for work they're performing, is asking you to give up that protection — and, in the owner-builder case, to take on liability that belongs to the contractor.

Which edition of the code applies to your job

Florida updates its building code on a multi-year cycle, and each edition brings changes to the roofing provisions. Broward adopted the 2023 Florida Building Code, 8th Edition on December 31, 2023, and that is the edition governing current work in the county.

The edition that applies to your job is generally the one in effect when the permit is issued — which is why permit dates matter so much in Florida roofing, both for compliance and for the re-roofing provisions often called the 25% rule. When a new edition is on the horizon, the timing of a permit application can genuinely change the scope of work.

Editions change and local jurisdictions sometimes add amendments, so treat any edition reference as a starting point and confirm the current requirements with your building department before you commit to a scope.

Why it matters when hiring a roofer

HVHZ compliance is the difference between a roof that survives a Category storm and one that peels off. It also affects insurability — insurers want to see code-compliant, NOA-documented work. Always confirm your roofer pulls a permit and schedules the required inspections.

There is a paperwork trail worth keeping, too. The permit, the inspection approvals, the NOA documentation and the completed wind-mitigation form are what prove the roof's condition to a future insurer, a future buyer, and an adjuster after a storm. A roof with no documented history is worth less than the same roof with a clean file.

Our crews are fully licensed and insured, we pull the permit on every job, and we build to the HVHZ requirements above rather than around them. If you want to know what shape your current roof is in and whether its documentation is complete, a free inspection takes about 45 minutes and costs nothing.
