Shingle, metal, or tile in Tampa Bay: insurance, heat, and storms

When a roof around the bay comes up for replacement, the first question a contractor asks is what you want on it, and most homeowners answer with the roof they already have. That is a fine answer in Brandon and a debatable one on Clearwater Beach. Here is how the three coverings used here compare on the things that actually cost or save you money: the wind rating, the insurer’s age rules, the wind-mitigation credits, heat, and the installer.

The number every roof has to meet

Tampa Bay is outside Florida’s High-Velocity Hurricane Zone, so the HVHZ-only rules (Miami-Dade NOA-only products, the HVHZ fastening schedules) do not apply here; a Miami-Dade NOA is still accepted statewide as evidence that a product is approved. What applies is the Florida Building Code’s wind map and, in Pinellas, a county-wide figure: Pinellas County’s local amendment to the code sets the ultimate design wind speed for ordinary homes at 145 mph everywhere in the county. Hillsborough uses the code’s map at similar speeds. Every covering, underlayment, and fastener carries a Florida Product Approval showing it was tested for that use, and the contractor’s job is to match the product and the installation pattern (nail count, clip spacing, tile attachment) to the site’s number.

For context, Milton’s measured gusts on October 9, 2024 were 93 mph at Tampa International and 101 mph at Albert Whitted in St. Petersburg. Airport gust readings say what the wind did at the airport, not why any one roof failed; that takes an inspection of the roof itself. The design number is well above what the storm delivered; the installation is what decides whether the roof meets it.

Architectural shingle

The Tampa Bay default: the lowest cost per square (a roofing square is 100 square feet of roof surface), installed by every contractor around the bay, and available in systems approved for the county’s design wind speed when installed with the fastening pattern the approved product and the local code require, and a starter strip with its own seal.

• Life: 20 to 25 years for an architectural shingle in this sun; 15 to 18 for the three-tab shingle builders used in Riverview and Brandon in the 2000s.
• Insurance: the shingle roof is the one the age rules are written around. Under Florida Statute 627.7011(5), roof age alone cannot be the insurer’s reason for refusing to write or renew while the roof is under 15 years; at 15 or older, an inspection showing five years of remaining life blocks a roof-age refusal. Citizens requires documentation of remaining life at 25 years for shingle. A shingle roof has a clock the insurer reads from the permit date.
• Wind mitigation: a new shingle roof can document three separate items on the OIR-B1-1802 form: the roof covering (the shingle system and its product approval), the secondary water barrier (an approved, code-compliant underlayment system; self-adhered membrane is the common choice), and the roof-deck attachment (how the plywood or boards are nailed to the trusses, which is separate from how the shingles are nailed). Ask the contractor to photograph the deck nailing before the underlayment goes on; the inspector who signs the form needs to see it.
• Heat: a dark shingle roof over a vented attic runs hot in August; lighter colors and ridge venting help, and the HOA color list in Riverview or Tampa Palms may limit the choice.

Standing-seam metal

The post-Milton choice on the barrier islands, in South Tampa, and for anyone who wants to stop thinking about the 15-year clock. Vertical panels joined by raised seams, fastened with hidden clips that let the metal expand, no screws through the surface.

• Life: 40 to 50 years, with a finish warranty (often 30 or more years against chalking and fading) that is separate from the workmanship warranty.
• Insurance: Citizens treats metal as a “hard” roof, with its documentation rule starting at 50 years instead of 25. The 15-year statute still lets an insurer ask for an inspection at 15, but a 15-year-old standing-seam roof passes it.
• Wind mitigation: the same credits as shingle, and the clip spacing and fastening on the plan are what make the installed system meet the 145 mph design wind speed for the property in Pinellas.
• Salt: on Clearwater Beach, Sand Key, and Davis Islands, aluminum instead of steel, because cut steel edges rust near salt water. Steel panels are specified by gauge (24 is common on houses); aluminum by thickness (.032 inch is common), so compare the right number for the metal being quoted.
• The installer: this is the trade-off. Metal is a different trade from shingle, and most metal-roof leaks come from a shingle crew installing its first standing-seam roof: seams not hemmed, clips too far apart, penetrations sealed with caulk. Ask who is installing it and how many they have done.
• Exposed-fastener metal (5V crimp, corrugated) is cheaper and traditional on old Florida houses, but the gasketed screws are a maintenance item every several years.

Tile

The South Tampa, Snell Isle, and Harbor Oaks roof: concrete or clay barrel tile over a wood-framed roof, the look of the 1920s Mediterranean Revival houses and the newer houses built to match them.

• Life: the tile lasts 50 years or more; the underlayment beneath it, which does the actual waterproofing, lasts 25 to 30. A “tile roof leak” is almost always an underlayment failure, and a tile re-roof is usually the same tile relaid over new underlayment.
• Insurance: Citizens’ 50-year rule for tile. The 15-year statute applies to the roof as a whole, and the inspection report will say what the underlayment’s age is.
• Wind: tile is heavy and attached with approved mechanical fasteners (screws or clips) or an approved adhesive system (foam), depending on the tile system, to the code’s wind number; the attachment method is on the Florida Product Approval and on the permit.
• Foot traffic: satellite installers, pressure washers, and tree trimmers crack tile by walking on it. The cracked tile is the leak in three years.
• Historic districts: parts of Hyde Park, Tampa Heights, and Seminole Heights are local historic districts where a change of roof material on a contributing house needs a Certificate of Appropriateness from the city’s Architectural Review Commission; in the Ybor City Historic District the reviewing body is the Barrio Latino Commission. West Tampa is a National Register district, which by itself does not trigger the city’s review; its individually designated local landmarks do. District lines do not follow neighborhood names, so check whether your address is inside one. Tile to metal is a review, not a decision.

Which one, then

If the house has a shingle roof and is in Brandon, Riverview, Carrollwood, Pinellas Park, or Countryside, another architectural shingle roof with a secondary water barrier, fastened the way the approved system and the code require, is the sensible answer, and the insurer will read a 2026 permit date for the next 15 years. If the house is on the water, on an island, or if the owner plans to be there for 20 years and wants to be done with the clock, standing seam from an installer who does metal is the answer worth pricing, with the premium difference from your agent in the same spreadsheet. If the house has tile, it almost certainly wants tile again, on new underlayment, and the question is the attachment method and the installer’s experience with the roof’s pitch.

Whichever covering: the proposal names the product and its Florida Product Approval number, the underlayment, the fastening or clip pattern, the permit in the contractor’s license, and two warranties in writing.
