New construction roofing in New Port Richey, FL

Roof sheathing is nailed with ring shank nails, 2 1/2 inches long. The code names ASTM F1667 RSRS-03 nails, with RSRS-01 or RSRS-04 allowed where the sheathing is 15/32 inch or thinner. Ring shank nails grip better than smooth ones, which matters in the wind that came through during Helene, when a gust of 56 mph was recorded near New Port Richey.

Shingle and metal roofs get one of three dry-in methods. One is self-adhering underlayment over the whole deck. Another is a strip of membrane or tape, at least 3 3/4 inches wide, over every deck joint, then underlayment over all of it. The third is two layers of felt-type underlayment, nailed 12 inches apart in the field and 6 inches apart at laps.

Roofing falls under mandatory statewide product approval. The permit application should list the approved product, and you can look up any approval number in the Florida Building Commission search. A 2018 tornado here left some homes with shingles and roofing felt blown off, which shows why the underlayment step is not optional.

Your New Port Richey inspector will sign off roof work in two steps. First comes the sheathing inspection, covering roof and wall sheathing, fasteners and the dry-in. Later the roofing inspection checks dry-in, insulation, roof coverings and flashing, ahead of the final.

A general or residential contractor may install asphalt or fiberglass shingles on a new building of its own construction. Tile, metal and membrane go to a certified or registered roofing contractor. Record the Notice of Commencement and post it at the job before the first inspection, or you risk paying twice for the work.

Permits expire if work does not start within 6 months of issuance. They also lapse if work stops for 6 months, so build the roofing date into the schedule early. Gutters with downspouts are required where eaves project less than 6 inches, and downspouts discharge at least 1 foot from the wall.
