New construction roofing in Madeira Beach, FL

On a new shingle, metal or similar roof, the deck must be dried in with one of three approved underlayment methods. The simplest is a full self-adhering polymer-modified bitumen layer over the entire deck. The other two use tape over every deck joint, or two layers of felt fastened at set spacing.

• Roof sheathing is fastened with ring shank nails, typically RSRS-03 where sheathing is thicker than 15/32 inch.
• Drip edge at eaves and gables is fastened 12 inches on center, or 4 inches where design wind speed is 110 mph or more.
• Tile goes only over solid sheathing unless the product is tested otherwise.

Every roofing product sold in Florida falls under the state's mandatory product approval program. Check the Florida Building Commission product approval search by FL number before you buy materials, and keep the approval number on the permit. A product may not be marketed as impact or windborne debris protection unless it holds that approval.

The code orders inspections so the roof comes after framing and sheathing. Roof sheathing gets its own inspection, either with the dry-in or separately once all decking and fasteners are complete. Before the final, the inspector checks dry-in, insulation, roof coverings and flashing.

Permits expire if work does not start within 6 months of issuance, or if work is abandoned for 6 months. Schedule the roof crew so the roofing inspection happens while the permit is active. Where eaves sit under 6 inches, you need gutters, and each downspout has to carry water at least 1 foot away from the wall.
