How to Compare Metal Roof Quotes in Florida Before You Sign

Start with the roof system itself

You can't compare metal roof quotes if the quotes aren't describing the same thing. And most of the time, they're not.

The two main types are exposed-fastener panels and standing-seam panels, and the difference between them is bigger than the name suggests. Exposed-fastener means screws go straight through the metal surface, each one sealed with a rubber washer. It's less expensive up front. The tradeoff is that every screw is a potential leak — the rubber washers break down in Florida sun, screws back out from thermal cycling, and the panels can't expand and contract freely. You'll get 20 to 30 years with maintenance.

Standing seam hides the fasteners underneath raised, interlocking seams. No screws through the surface, no rubber washers to degrade, and the panels can move with temperature changes without fighting against their own fasteners. These systems cost 30% to 50% more, but they typically last 40 to 60 years with significantly less maintenance.

If a quote just says "metal roof" without specifying which system, you're comparing a number to nothing. Ask.

Scope details that change price

The cheapest quote on the table usually isn't cheap by accident. Something was left out.

Underlayment is the first place to check. Florida code requires specific underlayment for metal roofing, and the type matters. Synthetic costs more than felt. High-temperature ice-and-water shield at eaves and valleys adds cost but adds protection where it matters most. If the quote says "underlayment included" and nothing else, ask what kind.

Metal gauge affects both durability and price. Most residential work uses 26-gauge or 24-gauge. Lower number, thicker metal. 24-gauge resists dents better, handles wind loads better, and looks more finished over time. Some contractors default to 26 because it's cheaper without mentioning it on the quote.

Coatings are the long game. Galvalume is the baseline zinc-aluminum coating. Kynar (PVDF) finishes resist fading and chalking for decades. "Painted metal" on a quote could mean anything. It matters what it means because you'll be looking at the roof for 30 years.

Then there's flashing and trim — drip edge, valley metal, ridge cap, wall flashing, pipe boots. These are custom-fitted pieces that protect the transitions where water concentrates. A quote that lumps everything under "standard trim" is leaving room for the cheapest available option.

Labor and project details

Materials are half the story. The other half is what happens on your property during installation.

Is the old roof being torn off, or is the metal going over the top? Overlaying is cheaper but adds weight, hides whatever's happening with the deck underneath, and can void certain warranties. If tear-off is included, does the quote account for the number of existing layers? Two layers of old shingles coming off is a different job than one.

How is the property being protected? Metal panels have sharp edges. Cutting generates metal shavings. Your landscaping, siding, windows, and driveway are all in the work zone. The quote should address site protection, not leave it to chance.

Deck repair language is critical. When the old roof comes off, damaged plywood often shows up underneath. A clear, pre-agreed per-sheet price for replacement sheathing — written into the contract — eliminates the most common cost surprise on a metal roof project. If it's not in there, it becomes a negotiation at the worst possible time: when your roof is open and you've got no leverage.

Timeline should be stated. How many days? What happens if weather causes delays? How is the roof secured overnight if the project spans multiple days? These aren't minor details when you're living in the house.

Warranty questions

A "40-year warranty" sounds great until you read what it actually covers. Usually: the metal panels. Not the labor. Not the flashing. Not the underlayment. Not the installation details that cause most problems.

Metal roof warranties come in two layers. The manufacturer warrants the material — the panels and whatever coating is on them. The contractor warrants the workmanship — how everything was installed. A panel that's technically fine but was installed over improperly flashed penetrations is a failed roof with a valid material warranty. That distinction matters.

Ask specifically: How long is the workmanship warranty? Does it cover flashing, trim, sealants, and all the details — or just panel attachment? Is it transferable if you sell the house?

Some manufacturers offer enhanced system warranties when their products are installed by certified contractors. These often extend coverage to include labor for repairs, not just material replacement. Ask whether the contractor qualifies.

Read the exclusion clauses. In Florida, be especially cautious about "act of God" exclusions — which can be interpreted to exclude storm damage. The whole point of putting on a metal roof in Florida is storm performance. If the warranty doesn't back that up, it's not worth much.

How to spot an incomplete quote

"Install new metal roof — $18,500." That's not a quote. That's a number without a story.

If the proposal doesn't specify panel system, gauge, coating, underlayment type, and trim details, you have no way to compare it to a proposal that does. One might be a standing-seam system with Kynar coating and full flashing. The other might be an exposed-fastener system with painted 26-gauge panels and whatever trim the installer had on the truck. Both say "metal roof." They're not the same thing.

Missing deck repair language is one of the most common gaps. If the quote says nothing about what happens when damaged sheathing shows up during tear-off, that surprise is coming out of your pocket mid-project.

No exclusions section is a red flag. A good proposal tells you what's included AND what's not. If every possible thing seems covered at a surprisingly low price, something is missing — you just don't know what yet.

We've been doing metal roofing in Florida for over 40 years. We buy direct from the manufacturer — no middleman markup. Every line item in our proposals is specific: system, gauge, coating, underlayment, flashing, deck repair terms, cleanup, warranty. You see exactly what you're getting and what it costs. No surprises, no vague language, no fine print that changes the deal.
