New construction roofing in Longboat Key, FL

Only 2.9 percent of homes on Longboat Key were built in 2010 or later, so most roofing work here is on older buildings. New roofs go on a small number of lots and on rebuilds. Each one still needs a Town permit, a county or state product approval check and inspections in a set order.

Code and permits

What a new roof on Longboat Key has to meet

A new roof permit here goes through the Town of Longboat Key Building Division. The Town runs its own building department, so you apply there, not to Sarasota County.

Longboat Key permits submitted on or after December 31, 2026 are reviewed under the Ninth Edition. Permits filed earlier stay under the 2023 edition. Ask the Town which edition covers your plans before you file.

Roofing is a statewide product approval category. The approval number and the product's Notice of Acceptance details go on the permit application. You can look up an approval number in the state's public product approval search, by FL number or manufacturer.

Build details

Components of a new roof: decking, underlayment, and drip edge

For roof sheathing, the fastener you must use is the ring shank nail. RSRS-03 nails are the standard. Where sheathing measures 15/32 inch or less, RSRS-01 or RSRS-04 nails may be used.

  • Option one: a full deck covering of self-adhering polymer-modified bitumen underlayment
  • Option two: a 3 3/4-inch membrane strip over every deck joint, then approved underlayment across the roof
  • Third option: install two layers of approved felt-type underlayment, with fasteners spaced 12 inches on center across the field.

Drip edge fastens at the eaves and gables over the underlayment, at no more than 12 inches on center. On a home where the mean roof height is over 33 feet, the spacing tightens to 4 inches.

Inspection order

Plan the roofing phase so it lines up with the construction schedule and each inspection along the way

The code sets the inspection order: foundation, framing, sheathing, exterior wall coverings and soffit, then roofing, then final. Roofing inspection checks dry-in, insulation, the roof covering, and flashing. Schedule the roofing inspection only after the sheathing is complete.

Should work not start within 6 months after the permit is issued, the permit expires. Work also lapses after 6 months of no activity. Keep your inspections on schedule.

Record and post the Notice of Commencement on site before the first inspection takes place. Skipping it may mean the owner pays twice for the same improvements.

Questions

New construction roofing in Longboat Key: questions

How many new homes on Longboat Key were built recently?

Only 2.9 percent of homes on Longboat Key were built in 2010 or later, according to the 2024 American Community Survey five-year estimate. The median year homes were built is 1980, with a margin of error of plus or minus 2 years. That suggests most roofing work on the island involves older roofs being replaced rather than new roofs on new lots. Check the Town's current records if you are planning a new build.

Any application submitted on or after December 31, 2026 falls under the Ninth Edition of the Florida Building Code.

Who can install the roof on a new home on Longboat Key?

A general contractor must subcontract roofing work unless it holds a state roofing certificate or registration. On a structure a builder constructed itself, asphalt or fiberglass shingles can be installed by that builder. Work on tile, metal, and membrane roofs must be assigned to a certified or registered roofing contractor. Many homes on Longboat Key were built around 1980, so older roofs may need this kind of licensed work when replaced. You can check a contractor's status with the Florida Department of Business and Professional Regulation.

Does a new Longboat Key home come with a builder warranty?

Under Florida Statute 553.837, a builder must back a newly built home with a 1-year warranty covering defects in equipment, materials or workmanship that lead to a material violation of the Florida Building Code. That clock begins at whichever comes first: the original transfer of title or the first day of occupancy. Coverage does not extend to ordinary wear, settling, defects the owner causes, or acts of God such as natural disasters. Read your purchase contract and ask the builder about its coverage terms.
