Roof covering families, and what Florida approval actually means

The approval requirement first

Section 553.842 requires products that require approval to be approved before use in Florida, and names roofing among the product types for which the approval method in subsection (5) must be used. Approval may rest on a certification mark or listing, a test report, an evaluation entity's report, or a Florida-licensed engineer's or architect's report, and the Miami-Dade Product Control Division is named as an approved evaluation entity. The statute also states that marketing a product as hurricane, windstorm or wind-borne debris protection without approval falls under the Deceptive and Unfair Trade Practices Act. The implementing rule chapter is 61G20-3, whose scope rule was last amended 4-1-14. The state's own search tool lists roofing as one of eight product categories and filters by approved for use inside and outside the high-velocity hurricane zone, with FL numbers searched as an application number or a product number.

Where the high-velocity hurricane zone is matters here: the Miami-Dade Product Control brochure states that all Florida counties other than Miami-Dade and Broward are non-HVHZ areas under the Florida Building Code, further divided by a wind-borne debris region and wind-speed contours. Sarasota County is therefore outside the HVHZ, which means an HVHZ-only approval is not the relevant one here and a non-HVHZ approval is not a lesser product. The brochure also states that roofing products are among those approved through a Notice of Acceptance and that roofing fasteners in approved notices must meet corrosion testing for HVHZ use.

Asphalt shingle

This is the most commonly published family and the one where the manufacturers' Florida statements diverge most. CertainTeed describes Landmark PRO as a fiberglass mat coated with asphalt and ceramic-coated granules and states no Florida, Miami-Dade or HVHZ position at all. IKO describes Cambridge as a fiberglass-core laminated shingle and does list Miami-Dade Product Approval and Florida Building Code HVHZ approval, stated to apply only to shingles available in the U.S. Southeast market. TAMKO's Titan XT page and Atlas's Pinnacle Impact page both state high wind figures and no Florida approval. Malarkey's Vista AR, a polymer-modified shingle, prints FBC Approval #14809 under testing compliance. Four of those five pages are silent on Florida; that silence is a fact about the page, not about the product.

Metal panel

The metal manufacturers publish approvals most concretely, which is unsurprising for a family whose Florida market is large. Tri County Metals prints Florida Product Approval 36904.2 for non-HVHZ and 36904.3 for HVHZ across TCM-LOK, SL-LOK, MS-LOK, SS-LOK, PBR, 5V and Ultra Rib panels, with 36904.1 for open framing over steel purlins, and lists Miami-Dade notices 24-1022.02 through 24-1022.08. Gulf Coast Supply links separate HVHZ and non-HVHZ approval documents per panel, naming which panels have both and which have non-HVHZ only. McElroy Metal lists approval documents by title and date rather than number. Drexel Metals publishes its panel profiles without a Florida statement. Panels divide into concealed-fastener and exposed-fastener profiles, which is the distinction a quote should name.

Concrete and clay tile

Eagle Roofing Products publishes concrete tile profiles grouped as high barrel, medium, flat and lightweight, and lists FL7473 R11 dated 7/23/25 under both non-HVHZ and HVHZ entries together with an IAPMO evaluation report, a TRI report and FM 4473 hail impact certification for three plants. Crown Roof Tiles publishes a Florida Signature Series of concrete profiles and links its Florida approval pages without printing the numbers, while naming its Miami-Dade notice documents. On the clay side, Santafe Tile publishes profiles with no approval statement, and Ludowici publishes more than 40 terra cotta profiles and promotes a factory-trained installer program. Tile is heavy, and nothing here establishes that any particular roof structure can carry a particular tile.

Underlayment, the layer that is rarely quoted

Polyglass publishes Polystick and Polyanchor self-adhered and mechanically attached underlayments including a TU-series for tile, alongside modified bitumen membranes, coatings and single-ply PVC. Drexel Metals and Gulf Coast Supply both publish underlayments beside their panels, Gulf Coast naming GulfShield HT and Nail N' Seal. Underlayment matters twice over in this market: it is part of the assembly an approval covers, and the state's wind mitigation form treats a sealed roof deck as a separate credited attribute. None of the index pages read for this draft carries approval numbers.

What this guide does not settle

An approval applies to an assembly, not to a product in isolation: the deck, the underlayment, the fastening pattern and the wind zone are all part of it. No number recorded here was looked up in the state's approval system or in the Miami-Dade notice directory, and no page's silence about Florida was treated as an absence of approval. Whether a particular product is approved for a particular roof is a determination for the approval documents and the local building official.
