New construction roofing in Lighthouse Point, FL

On a new roof, the deck must be dried in before finish roofing goes on. For shingle and metal roofs, the code offers three options for getting the building dried in. One is a fully adhered polymer-modified bitumen underlayment. Another is tape over every deck joint with a full underlayment. The third is two layers of approved felt, nailed on set spacing.

• Drip edge at eaves and gables, nailed no more than 12 inches apart, and 4 inches apart where wind speed is 110 mph or more.
• Roof sheathing nailed with ring shank nails, using the RSRS-03 standard for most decks.
• Tile only over solid sheathing and installed to the manufacturer or FRSA/TRI manual.

Any product sold as wind or debris protection must carry a statewide approval number. Check the Florida Building Commission product approval search by FL number before you accept a material. In the HVHZ, the permit application carries those numbers.

The code lists the roof inspections in order: framing after the roof is framed, sheathing or dry-in after all sheathing and fasteners are done, and roofing after dry-in, insulation, covering and flashing. Plan the roof crew's visits around those steps so the inspector sees each stage before it is covered.

The material determines who is allowed to do the installation. On a new building they own, a builder can put down asphalt shingles personally. Work involving tile, metal or membrane must be performed by a roofing contractor holding certification or registration. A permit also expires if work stops for 6 months, so keep the job moving.
