The honest answer is that it depends on your lot, how long you are staying, and what the fasteners are made of.
This comes up on most replacement estimates we give in Gulf Shores. Here is how we actually think about it, including the cases where we recommend shingles over metal.
Metal costs more up front. Depending on the system and the complexity of the roof, a standing seam metal roof will typically run well above an architectural shingle roof on the same house.
Over a long enough ownership period the maths shifts, because a properly specified metal roof on this coast should outlast two asphalt roofs. If you are staying fifteen or twenty years, metal usually wins on cost per year. If you are likely to sell inside five, shingles almost always make more financial sense.
Forget the numbers on the packaging — they assume a gentler climate. On the Alabama Gulf Coast:
Asphalt shingles realistically deliver 15 to 20 years, against the 25 or 30 printed on the wrapper. UV, heat, humidity and storm wind all shorten asphalt life here.
Metal substantially outlasts that — provided the coating and fasteners are right for salt exposure. Get those wrong within sight of the water and it will disappoint you in well under a decade.
Ventilation affects both. An under-ventilated attic cooks a roof from underneath and takes years off either system.
This is where metal has a real structural advantage, and it is not marketing.
An asphalt shingle roof is held down by adhesive seal strips. Wind works on individual tabs, and once one lets go it exposes the next. That is precisely how storm damage propagates across a slope.
A standing seam metal roof is mechanically locked and fastened, with no exposed tab for wind to peel and no adhesive that UV degrades over time. Under sustained uplift — which is what a hurricane actually is — that is a meaningfully better system.
Both can be installed to Baldwin County’s 130 mph requirement. Metal simply has more headroom above it.
If you take one thing from this article: on a coastal metal roof, the coating and the fasteners matter more than the panel.
Airborne salt attacks the weakest metal on the roof first, and that is almost always the fastener. A roof with excellent panels and mediocre screws will stain, then weep, then leak, long before the panels are anywhere near finished. Dissimilar metals in contact corrode each other galvanically, so the panels, flashing and fasteners have to be considered as a system.
This is why two metal quotes at the same price can have completely different service lives within a mile of the beach — and why we will not simply price-match a metal roof without knowing what is in it. Ask every bidder what the fasteners are made of and what the coating system is. A vague answer is an answer.
There is a middle option. Stone-coated steel gives you a steel substrate with the appearance of shingle or tile — metal wind and impact performance, without a metal look. It is frequently what we recommend where an HOA will not approve standing seam.
We lean metal on exposed lots — beachfront, the Fort Morgan peninsula, anything with clear fetch to open water; on homes you plan to keep long term; where debris impact is a recurring problem; and where a lower long-run insurance position matters.
We lean shingles on more sheltered inland lots in Foley or Elberta; where budget is the binding constraint; where you may sell within a few years; and where an HOA restricts the roof appearance and stone-coated steel is not viable.
Either way, ask about FORTIFIED before you decide. A sealed roof deck under either covering is the upgrade that keeps water out of the building when the covering fails, and Alabama will fund up to $10,000 of it on an eligible owner-occupied home.
"Metal roofs are loud." Not over a solid deck with proper underlayment. The stereotype comes from bare metal over open purlins on barns.
"Metal attracts lightning." It does not. And because metal is non-combustible, it generally reduces fire risk if lightning strikes nearby.
"Metal roofs make the house hotter." The opposite, typically — metal reflects more solar radiation than dark asphalt absorbs.
We do free roof inspections across Gulf Shores, Orange Beach, Fort Morgan, Foley and the rest of south Baldwin County. We get on the roof, photograph what we find, and tell you what it actually needs — including when the answer is nothing. Call (251) 313-4853 or request an estimate.
We will price metal and shingles on your actual roof — including what the fasteners and coating are.
