The Best Metal Roof for Florida Homes
Quick answer
For Florida, aluminum metal roofing is an excellent choice: it stands up to hurricane wind, salt air, intense sun, and humidity all at once. Interlock is warranted to 120 mph and carries Florida Product Approval FL7263 for statewide use outside the High-Velocity Hurricane Zone (Miami-Dade and Broward), plus a cool-roof finish that cuts cooling costs and no-rust aluminum for the coast.
What Florida roofs are up against
Few climates test a roof like Florida's. Hurricane and tropical-storm winds try to lift the roof; relentless sun and heat drive up cooling bills and degrade lesser materials; humidity and frequent rain invite moisture problems; and coastal salt air corrodes anything iron-based. A Florida roof has to answer all of these at once — which is exactly where aluminum metal roofing excels.
How aluminum roofing answers each challenge
Interlock's interlocking aluminum system is built for this. For wind, it carries Florida Product Approval FL7263 with engineer-sealed design pressures up to −187.5 psf and a 120 mph warranty, and its four-sided interlock resists the uplift that peels shingles. For salt air, aluminum simply cannot rust — the standard choice for coastal Florida where steel roofs corrode. For heat, the cool-roof Alunar finish reflects solar energy to lower cooling costs. And metal sheds Florida's heavy rain without absorbing moisture.
A note on the Hurricane Zone, and choosing
One important detail: Interlock's FL7263 approval covers Florida statewide except the High-Velocity Hurricane Zone (Miami-Dade and Broward counties), which requires its own approval track — homeowners there should confirm current options with Interlock and their building official. Everywhere else in Florida, FL7263 is the documentation your building department wants. When choosing, match the profile to your home's style and pick a reflective color for maximum cooling savings.
Frequently Asked Questions
What is the best roof for Florida?
Aluminum metal roofing is among the best — it resists hurricane wind, cannot rust in salt air, reflects heat, and sheds heavy rain. Interlock carries Florida Product Approval FL7263 and a 120 mph warranty.
Is Interlock approved for the Florida Building Code?
Yes — Interlock holds Florida Product Approval FL7263 for statewide use outside the High-Velocity Hurricane Zone (Miami-Dade and Broward), with engineer-sealed design pressures up to −187.5 psf.
Can I use an Interlock roof in Miami-Dade or Broward?
FL7263 is a Non-HVHZ approval, so it does not cover Miami-Dade and Broward, which require their own approval track. It's valid throughout the rest of Florida; HVHZ homeowners should confirm options with Interlock.
Does a metal roof handle Florida heat and humidity?
Yes. The cool-roof Alunar finish reflects solar heat to cut cooling costs, and aluminum doesn't absorb moisture or rust, so it handles humidity and salt air far better than many alternatives.
