Metal Roofing in Miami & South Florida

01 / 07

1. 01

   Solid, well-nailed deck

   After the tear-off, damaged sheathing is replaced and the deck is nailed down to the framing wherever the existing nailing falls short. The clips that hold the panels screw into this deck, so it has to be solid everywhere.

   In Florida On homes permitted before the Florida Building Code took effect in 2002, code calls for adding ring-shank nails where the existing deck nailing falls short.

2. 02

   High-temp underlayment

   Typically, a high-temperature self-adhered underlayment covers the deck. Heat builds up under metal panels in the Florida sun, where standard self-adhered underlayments can break down. This layer is rated to stay sealed at those temperatures.

3. 03

   Eave and rake trim

   Matching metal trim goes along the eaves so the panel ends hook in and water drips clear of the fascia. Rake trim goes on before or after the panels, depending on the system, and the panel maker's details set how trim laps the underlayment.

4. 04

   Concealed clips

   As each panel is set, clips are screwed to the deck over its raised edge, closer together near the roof's edges and corners where wind pulls hardest. They hold the panels down without putting a hole through them. Some systems use a hidden fastening strip instead.

   In Florida Clip type and spacing come from the panel's product approval and the wind pressures calculated for your roof.

5. 05

   Standing seam panels

   Panels usually run from the eave to the ridge in one piece. Each new panel locks over the clips and the edge of the last one, either by snapping together or by being mechanically seamed.

   In Florida In the High Velocity Hurricane Zone (Miami-Dade and Broward), the panel system must be approved for that zone, often through a Miami-Dade NOA.

6. 06

   Ridge cap

   A ridge cap with closures finishes the peak, and it can be vented. Closures fill the shape of the panels under the cap to help keep wind-driven rain and insects out.

7. 07

   Inspect and close out

   The building department inspects during the job and at the end, and we close out the permit. We sweep metal shavings off the panels as we work, since they can rust and stain the finish.

General sequence only. Underlayment, edge details, clip spacing, panel gauge and seaming vary by system. Your proposal and permit list the exact products and product approvals.
