New construction roofing in Loxahatchee Groves, FL

Roof sheathing on a new home must be fastened with ASTM F1667 RSRS-03 ring shank nails, which are 2 1/2 inches long, or RSRS-01 or RSRS-04 where the sheathing is 15/32 inch or less. Your framer and roofer should agree on the nail type before the deck goes up.

Shingle and metal roofs need a dry-in underlayment method. You may cover the whole deck with self-adhering polymer-modified bitumen, or use a tape strip over every joint with an approved underlayment, or use two layers of approved felt fastened to the schedule the code gives. Pick the method on the permit drawings so the inspector sees it at dry-in.

• An inspector checks the framing and bracing once the roof structure is complete.
• Sheathing or dry-in inspection once all roof and wall sheathing and fasteners are complete.
• A second inspection looks at dry-in, insulation, the roof covering and flashing.
• Final inspection after the work is complete.

Statewide product approval applies to roofing products across the board. Before you buy a shingle or tile for a new home, look up its Florida Building Commission approval number and confirm it on the permit. A product may not be advertised as wind or impact protection unless it has that approval.

Asphalt shingles can be put on a new building by the person who builds it. Work on tile, metal or membrane roofs has to be handed to a certified or registered roofing contractor. A general contractor may not advertise itself as a roofer without that certification or registration.

Gutters and downspouts are required on most new homes with eaves under 6 inches, and downspouts must discharge at least 1 foot from the wall. Plan the gutter layout with the roof so the water path is set before framing is finished.
