Where to Buy Metal Roofing in Florida: Manufacturer Programs vs. Suppliers

What are the three ways to buy a metal roof in Florida?

Most people who search for metal roof suppliers near me in Tampa, Orlando or Fort Myers are not looking for a pallet of panels. They want a finished roof on the house, and they are trying to work out who sells it. In Florida the answer comes in three shapes, and the shape determines who is responsible when something goes wrong. The first is retail. Big-box home centers and farm supply stores across the state stock ribbed and corrugated steel panels in a handful of colors, cut to stock lengths, with matching screws and trim. The customer buys the material and either installs it or hires someone to. The second is wholesale: roofing distributors in every Florida metro carry steel and some aluminum systems from multiple manufacturers, sell to licensed contractors and sometimes to the public, and leave the choice of installer entirely to the buyer. The third is a manufacturer program. The manufacturer sells a complete roofing system, certifies contractors to install it, assigns one of those certified installers to each project, and issues its own warranty on the material. The homeowner's contract is with the licensed installer; the product and warranty are the manufacturer's. Metal Roofing Florida works this way for Interlock aluminum roofing in Florida.

What do you get with big-box panels?

Retail metal roofing in Florida is almost always 29-gauge exposed-fastener steel, galvanized or Galvalume, with a polyester or silicone-polyester paint. It is inexpensive by the sheet, available today, and adequate for a shed, a barn or a lanai roof in Ocala or Spring Hill. It is the product most people picture when they think of a tin roof, and its popularity in the Panhandle and the rural interior comes from that availability. As a house roof on the Florida coast it has real problems. Exposed fasteners mean thousands of screws through the panel face, each with a rubber washer that ages under UV and each a path for salt film to reach the steel. Cut edges at eaves and rakes are bare steel, and on the Space Coast or the Pinellas beaches edge rust appears within a few years. The retail path also leaves the homeowner responsible for everything the code requires. The reroof permit must still be pulled by a licensed contractor, and it still triggers deck re-nailing and a secondary water barrier under 553.844. The panels must have a Florida Product Approval matching the profile and gauge sold, and the fastening schedule must meet the site's design pressure. A homeowner buying panels and hiring a handyman in Daytona Beach has none of that handled.

What changes when you buy from a distributor and hire your own contractor?

The distributor route is how most Florida roofing gets done. Distributors in Jacksonville, Orlando, Tampa, Sarasota and Naples stock full metal systems with matching flashings, underlayments and accessories, and the contractor the homeowner chooses orders from them. The product quality can be high, including some aluminum systems, and the contractor takes responsibility for the installation under their DBPR license. The homeowner's job in this path is to find and vet the contractor, and to make sure the product and its Florida approval match. That is more work than it sounds. A contractor who mostly installs shingles may propose a metal system they have installed twice. The product approval on the permit must be for the exact profile, gauge and fastening being installed, and design pressures on it must meet the site's wind speed, whether that is 130 mph in Orange Park or 170 in Collier County. Many homeowners have no way to check that the permit set matches what went on the roof. Warranty in the distributor path is split. The manufacturer warrants the material and finish; the contractor warrants the workmanship, usually for a few years. When a leak appears in year eight, each can point at the other, and the homeowner in Palm Coast is the one who has to prove which it was. The material warranty may also have conditions the contractor did not meet, such as fastener type near salt water or a specific underlayment, that void it without anyone noticing at the time.

How does a manufacturer program work in Florida?

In a manufacturer program the manufacturer takes on the coordination the homeowner would otherwise do. For Interlock in Florida, Interlock Roofing manufactures the aluminum roof, and Metal Roofing Florida trains and certifies independent licensed roofing contractors to install it to specification, and assigns a certified Interlock installer to each project. The homeowner contracts with that installer; the installer pulls the reroof permit under their own DBPR roofing license and performs the work; the manufacturer backs the Guardian Lifetime Limited Material Warranty. The warranty is the main reason the model exists. Guardian covers the original owner for as long as they own the home and transfers once, to 50 years from substantial completion when registered within 60 days, with warranted wind resistance of 120 mph when installed to manufacturer specification and coverage for splitting, cracking and perforation from hailstones 1.5 inches or less. Because the manufacturer certifies the installer on this system, the installer assigned to your project works to the same specification the warranty's wind figure depends on. The finish, Alunar 70 percent PVDF under AAMA 2605, carries its own 30-year warranty. Product approval and permit compliance travel with the system. Florida Product Approval NEMO P.E. Evaluated FL7263-R7 covers the Shingle, Slate, Diamond, Shake and Hidden-Fastener Tile profiles in 0.019 to 0.027 inch aluminum, tested under UL 1897, UL 580 and TAS 125, with design pressures from -30.0 to -187.5 psf by profile and fastening. The certified installer puts that approval on the permit set and selects the fastening for the site's ASCE 7-22 wind speed. The 553.844 deck re-nailing and secondary water barrier are part of every permitted job. The honest limits are these. Metal Roofing Florida does not install and does not hold a Florida roofing license; the assigned installer does, and the homeowner should verify that license with DBPR. There is no Florida installation record to point to, and none is claimed. Standing seam is not in NEMO P.E. Evaluated FL7263-R7 and is not offered in Florida. Miami-Dade and Broward, the HVHZ, are not served; Monroe County is considered case by case.

Which path should a Florida homeowner choose?

It depends on what is being roofed and how long the owner expects to be responsible for it. For an outbuilding in the Nature Coast or a detached workshop near The Villages, retail steel panels installed by a licensed contractor under a permit are a reasonable choice, provided the site is well away from salt water. For a house, the retail path carries the most risk and the least accountability, and its steel product is the one Florida's coasts treat worst. The manufacturer program suits a homeowner who is comparing manufacturers rather than contractors, who wants one warranty backed by the company that made the roof, and who wants the installer chosen and certified by that company rather than found through a search. It also suits coastal homes, because aluminum contains no iron and cannot rust, including on Sarasota, Naples or Jacksonville Beach projects. Whichever path is chosen, three things do not change in Florida. The reroof needs a permit, pulled by a DBPR-licensed roofer. The permit triggers 553.844. And the covering needs a Florida Product Approval for the profile actually installed, valid for the county, which for aluminum through Metal Roofing Florida means NEMO P.E. Evaluated FL7263-R7 in every non-HVHZ county. A homeowner who confirms those three items before signing has avoided most of what goes wrong with Florida metal roofs.
