Standing seam is the premium metal option for Florida homes, and its advantage is what it does not have: exposed fasteners.
Panels lock together at raised seams with clips concealed beneath. There are no fastener penetrations through the panel face to leak or back out over time.
Sheds heavy rain quickly, resists uplift when clipped and engaged correctly, and reflective finishes reduce attic heat gain.
Clip spacing for the wind zone, thermal expansion allowance, panel gauge, and flashing at penetrations and terminations. Oil-canning is usually a substrate flatness or handling issue.
Aluminum panels and corrosion-resistant fasteners near salt water.
