Metal Roof Inspections in Lake Mary & Heathrow: Inspection Checklist

By the Orlando Roof Inspection team · Updated June 2026 · 8 min read

A metal roof inspection checks the parts that actually fail first: your fasteners and washers, the seams and panel laps, the coating, and the flashing around every penetration. The panels themselves? Those usually last for decades. What lets water in is a backed-out screw, a tired rubber washer, or a cracked bead of sealant at a vent. Catch those early and I've seen metal roofs run 40 or 50 years without drama.

I see a lot of metal around Lake Mary and Heathrow, everything from clean standing-seam panels on the newer custom homes to exposed-fastener panels on porches, barns, and older builds. It holds up beautifully to our sun and storms, but I'll be honest with you, it's not maintenance-free. This checklist walks you through exactly what I look at on a metal roof, what counts as a real problem versus a harmless cosmetic quirk, and how all of it ties back to your insurance.

Why metal roofs are popular in Lake Mary and Heathrow

Drive through the gated communities around Heathrow or the newer streets in Lake Mary and you'll spot metal everywhere. There are good reasons for that here in Seminole County:

• Lifespan. A quality metal roof lasts 40 to 70 years, far longer than shingle, and that matters when you plan to stay in the house.
• Storm performance. Properly fastened metal shrugs off high winds, which is a real plus in hurricane country.
• Sun and heat. Reflective finishes bounce off our Florida heat and can shave a little off your cooling bill.
• HOA appeal. Standing-seam panels give that clean, modern look so many Heathrow and Lake Mary neighborhoods are after.

The two main types I run into here are standing seam, where the fasteners are tucked under raised seams, and exposed-fastener panels, where you can see the screws right on the surface. They age differently, so I inspect them differently too.

The metal roof inspection checklist

Here's the short version of what I document on a metal roof, and why each item earns a spot on the list.

A drone or close-up photo report really shines here, because a lot of these items are small enough to miss from the ground.

Fasteners, washers, seams, and laps

On an exposed-fastener roof, the screws and their little rubber washers are what actually do the sealing. And our sun is brutal on rubber. After 10 or 15 years, those washers dry out, crack, and quit sealing. Screws back themselves out too, because the metal expands and contracts every time the temperature swings. So here's what I'm looking for:

• Screws sitting high or crooked instead of pulled down flush.
• Washers that are cracked, flattened, or gone altogether.
• Over-driven screws that crushed the washer and dimpled the panel.
• Empty or stripped holes where a screw worked itself loose and fell out.

On a standing-seam roof the fasteners are hidden, so I shift my attention to the seams and the clips that anchor the panels to the deck. I'm checking for seams that have lifted or pulled apart, panel laps that no longer sit tight, and any hint that a clip has let go. Those open seams are exactly where wind-driven rain sneaks in during a storm.

Coatings, corrosion, and flashing

Think of the coating as your roof's sunscreen. A healthy finish sheds water and blocks UV. Over the years you might notice fading, a chalky residue, or peeling, and it usually shows up first on the south-facing slopes that bake all day. Light fading is purely cosmetic. Peeling down to bare metal is a different story, because bare metal is where corrosion gets started.

I look hard at cut edges, scratches, and any spot where two different metals touch, since those are the first places rust likes to show up. Caught early, a scratch gets touched up or the panel re-coated and you move on. Left alone, rust creeps under the finish and starts eating away at the panel.

Flashing at walls, valleys, chimneys, and skylights is where most metal-roof leaks really begin, not out in the open field of panels. I make sure the flashing is tight and properly lapped, and that the sealant at your vent boots and pipe penetrations hasn't dried out or pulled away. Down here sealant is a wear item, plain and simple, and it almost always needs renewing long before any panel does.

Oil-canning vs. real damage

Here's something that worries homeowners far more than it should: oil-canning, that gentle waviness you catch across flat metal panels in certain light. I get asked about it all the time. It looks like dents, but nine times out of ten it's just a cosmetic quirk of how the metal was rolled and installed. It does not mean your roof is failing.

Real, leak-causing damage looks different, and once you know what to watch for it's easy to tell the two apart:

I'll always point out oil-canning so you know it's there, but I won't write it up as a defect, because it isn't one. The things that actually earn a repair note are loose fasteners, open seams, corrosion, and failed flashing or sealant.

How metal performs in hurricanes and FL sun

When it's installed and fastened right, metal is one of the best roof choices you can make for our Central Florida storms. The panels resist uplift, they won't shed granules the way shingles do, and they don't crack like an aging tile. After a storm blows through, I focus the inspection on whether the high winds loosened any fasteners, lifted any seams, or peeled back flashing at the edges, since the edges are where uplift forces hit hardest.

Our sun is the slower, sneakier threat. It's all those years of UV and heat cycling that dry out your washers and sealant and fade the coating. That's exactly why even a metal roof that looks flawless from the street is worth a check every few years.

The insurance and wind mitigation angle

A metal roof is usually good news when it comes time to deal with your insurance, and a clean inspection only makes that better. Florida carriers like metal because it stands up to wind, and a documented, sound roof helps you keep your coverage and can even earn you discounts.

• Wind mitigation credits. A wind mitigation inspection documents how your roof is attached and shaped on the OIR-B1-1802 form, and a well-fastened metal roof often qualifies for some meaningful credits.
• Remaining life. Carriers want to know how many good years a roof has left, and metal's long lifespan works in your favor once the fasteners, seams, and coating all check out.
• Repair before renewal. Catching backed-out screws, dried sealant, or a little early rust ahead of your inspection keeps a short list of fixes from turning into a coverage headache.

For most Lake Mary and Heathrow homeowners, the smart move is bundling the metal roof inspection with your insurance forms in a single visit. You walk away with the photo report, the condition assessment, and the exact documents your carrier is asking for.
