Every metal roofing salesperson in Fort Myers will tell you their product handles hurricanes. Most of them are selling something that hasn’t been tested the way real Florida weather tests it. When 130 mile per hour winds rip through Lee County, standing seam panels with concealed clips stay put. Exposed fastener systems lose screws at the edges and peel backward. The brochures looked identical. The storm results don’t. We install metal roofing we’d put on our own houses, and we won’t touch products we know fail under pressure.
Approval Numbers Aren’t Marketing Fluff
That Florida Product Approval number stamped on your panels means they survived controlled impact and uplift testing in a certified lab. No number means the manufacturer skipped the process and hopes you don’t ask questions. We spec systems rated for Miami-Dade High Velocity Hurricane Zone exposure because Fort Myers faces identical wind loads with looser enforcement. Your insurance company cares about documented ratings. Your building inspector cares. The storm doesn’t read marketing copy.
Exposed Fasteners Are Leak Points Waiting to Open
Screw-down metal panels put hundreds of holes through the roof surface. Every hole depends on a neoprene washer keeping water out. Fort Myers sun cooks those washers until they crack and shrink, somewhere between seven and 10 years out. Then you’ve got leak potential at every single fastener. Standing seam systems hide connections beneath interlocking ribs where UV and rain can’t reach. Higher upfront cost, yes. But decades without chasing leaks at screw heads changes the math completely.
Cheap Paint Fails in Coastal Air
Standard finishes chalk, fade, and lose adhesion within a decade in Southwest Florida conditions. Once coating fails, bare steel meets salt-laden humidity. Rust spreads beneath the surface where you can’t see it until panels need replacing. Kynar 500 and Hylar 5000 PVDF coatings resist UV degradation and chemical attack for 30 to 40 years. We won’t install metal roofing with anything less because we’re the ones getting the callback five years later.
Decking Condition Gets Ignored Too Often
Metal roofing installed over soft wood fails from underneath. We’ve torn off three-year-old roofs where the original crew never checked substrate moisture before screwing panels down. Rot that existed on day one spread under the new surface until everything needed replacing. We probe moisture content across the deck before any panel goes on. Readings above 18% mean that section gets replaced first. And we photograph what we find.
Thermal Movement Cracks Rigid Attachments
Fort Myers temperatures swing 50 degrees between afternoon peak and overnight low. Metal expands and contracts with every cycle. Fixed clip systems fight that movement and create oil canning, warped profiles, and fastener stress that shows up within the first year. Floating clip designs let panels slide as temperatures shift, keeping seams tight and surfaces flat. We engineer clip spacing for panel length, exposure angle, and local temperature ranges. Installers who skip this step create problems you’ll see fast.
Get Real Specs Before You Sign
Metal roofing done right outperforms every other residential option when winds exceed design thresholds. Done wrong, it fails in ways asphalt shingles never would. Waiting until storm damage forces your hand means choosing fast with limited options and inflated prices.
