Standing-seam aluminum and Galvalume reflect most of the sun's heat instead of soaking it up, don't rust in salt air when you choose aluminum, and carry the highest wind ratings of any residential roof. A metal roof costs more up front and is usually the last roof the house will need.

In Miami-Dade and Broward every metal roof must be built to its approved product system (the Notice of Acceptance), which sets the seam and the clip spacing. We'll show you which one your roof needs and why. Seam photos are illustrations.
The flat area between the seams can be smooth or have light ribs. The ribs stiffen the panel and soften glare and "oil canning", the slight waviness you can see on wide flat metal.
We install all four. Ask to see samples at your estimate. (Illustration.)

Metal roofs rarely need replacing; what fails is usually a flashing, a penetration or an exposed-fastener system from another contractor. We repair those. We replace when panels have been damaged by impact, or when a homeowner wants to move from an exposed-fastener roof to standing seam.

Within about a mile of the ocean or the Intracoastal, aluminum: it cannot rust. Inland, Galvalume gives a stiffer panel for less money.
It qualifies for the same wind-mitigation credits as any new roof, and some carriers give an additional credit for metal. Ask yours for the form; we supply the inspection paperwork.
