How much does a metal roof cost?

We're not going to put a number on a web page — any roofer who does is quoting a chart, not your house. The panel system, gauge, deck condition, pitch, and coastal fastener spec all move the number, and two identical-sized houses can land in very different places. The honest way to get a real number is a free on-site quote.

How long does a metal roof last in Alabama?

Metal is built for a multi-decade service life, and that holds up on this coast because the failure modes that shorten a roof's life here — salt-air corrosion and wind uplift — are exactly what a coastal-spec metal roof resists. The caveat: panel type, gauge, coating, and fastener class all move how long a given roof actually goes before it needs attention.

Is a metal roof worth it on the Gulf Coast?

For most homeowners staying past the payback horizon, yes — and the case here is less about the roof and more about what's under it. Metal holds up to wind and salt air better than typical shingle failure modes, and it can pair with the FORTIFIED standard for a roof built to stay on the house in a named storm. Whether it's worth it for your house depends on how long you plan to own it.

Standing seam vs. screw-down (exposed-fastener) metal roofing — which is better?

Different trade-offs, not a clear winner. Standing-seam has no exposed fasteners, so nothing corrodes or backs out under wind cycling, but it costs more up front. Screw-down is less expensive and faster to install, but the screws and their washers are the roof's long-term maintenance point — they age, and re-torquing them is real, periodic upkeep.

Does a metal roof cost more to insure or less?

That's a question for your insurance agent — but a metal roof built to the FORTIFIED standard qualifies for Alabama's mandated wind-premium credit, the same as any FORTIFIED-designated roof. Metal alone doesn't guarantee a discount; the documented designation does.

Every metal-roof cost page online leads with a per-square-foot number that means nothing on your house. We're not doing that. Here's the real factor model — the seven things that move the price — plus how to read a quote once you have one.

Why there's no chart on this page

A national per-square-foot average isn't your roof's number

Search "metal roof cost" and you'll find a wall of pages quoting a national per-square-foot range pulled from an industry average — never built from your roof, your panel system, or the coastal fastener spec this climate calls for. Publishing it anyway is the easy version of this page. What actually determines what you'll pay is a short list of real decisions on your specific house. Know those seven factors and you'll understand your quote, and be able to tell whether the roofer who wrote it actually looked at your roof.

The factor model

Seven things that move the number

Roughly in order of how much weight each one carries. The panel-system choice and what the deck looks like once it's open are the two biggest swings on almost every job.

Panel system: exposed-fastener vs. standing-seam
Exposed-fastener panels screw straight through the face into the deck. Standing-seam locks together at concealed clips with no exposed penetrations — nothing for salt air to find, and a bigger up-front cost. This one choice moves the number more than any other.
Gauge and metal type
Thickness and metal — steel, aluminum, or a coated hybrid — both move price and both move how the roof holds up in salt air and wind. A thicker gauge resists denting; aluminum doesn't rust. It's a real trade-off your roofer should walk through on your house.
Underlayment and deck condition
A synthetic or self-adhering underlayment costs more than builder-grade felt. Soft or under-attached decking found once the old roof comes off adds scope nobody can price from a photo — the single biggest swing factor on almost every re-roof.
Tear-off vs. over-frame
A tear-off strips to the deck, inspects it, and starts clean. An over-frame builds new decking and metal over what's there, which can skip disposal and labor but isn't advisable on every house. Which applies to yours is an inspection question.
Pitch and roof complexity
A steep pitch is slower and more dangerous to work. So is a roof with a lot of valleys, dormers, and penetrations — each one gets custom-flashed instead of run straight. A simple gable and a six-plane roof aren't the same job at identical square footage.
Coastal spec: uplift rating and fastener corrosion class
A roof built for this coast's wind field needs a panel system and fastener class rated for it — and on metal, corrosion class matters as much as the panel. Stainless or coated fasteners cost more and are why the finish doesn't streak with rust at every screw head.
Crew size and access
Easy ground access and clear staging space move faster than a lot boxed in by trees or a tight lot line. How long the job takes on your site is a real line item, and one an in-person walk tells you far better than a phone estimate.

Why the spec is different here

The storm record this roof has to answer to

A metal roof spec written inland and one written for Baldwin or Mobile County aren't the same document. Since 1950, 52 named systems have tracked within 100 miles of Mobile Bay, 14 of them still at hurricane strength. Salt air is the other half of it — the reason fastener corrosion class is its own line item on a coastal quote.

The payback isn't just the roof

Metal plus FORTIFIED changes the math

A metal roof's long service life is the obvious payback. The less obvious one: metal can be built to the FORTIFIED standard, IBHS's beyond-code wind and water standard for this climate, and a FORTIFIED-designated roof qualifies for Alabama's mandated wind-premium credit — a real, state-law discount, not a sales claim. Pairing the two isn't automatic; FORTIFIED has its own requirements and its own independent evaluation. But if you're already investing in metal, it's worth ten minutes to know what reaching the standard would take.

What FORTIFIED is The insurance discount, explained

Why this matters more on this coast

A roof that holds its fasteners and edges through a named storm is worth more here than inland — the reason the coastal spec isn't optional the way it might be treated elsewhere.

How to read a metal roofing quote

A real quote reads like a spec sheet, not a single line total. Here's what should be on it, and what to ask if it isn't.

Panel system and gauge, named specifically
The panel profile, the gauge, and the metal, named. "Metal roof" with nothing else specified isn't a spec.
Underlayment type
Synthetic, self-adhering, or felt — and rated for the panel system quoted. An easy line for a bid to leave vague.
Fastener class and clip spacing or screw pattern
The coastal-specific line most inland-written quotes skip. No mention of corrosion class means this climate wasn't priced.
Tear-off, disposal, and deck-repair allowance
Is tear-off included? Is there an allowance for deck repair, or is that an open-ended change order? Get the process in writing.
Flashing, ridge, and penetration detailing
Valleys, vent boots, and ridge caps are where metal roofs actually leak. "Trim" with no detail is worth a follow-up question.
Warranty terms, split out by part
Finish, material, and workmanship are three different warranties with three different lengths. Ask for all three, separately, in writing.
