The comparison, worked through for this coast specifically

Both work here. The honest answer depends on how long you are staying, how exposed the house is, and what your carrier does with each — and generic comparisons miss all three.

Side by side

Factor	Architectural shingle	Standing-seam metal
Installed cost	$12,500 – $18,000	$24,000 – $41,000
Life on this coast	20 – 25 years	40 years or more
Wind performance	Class H, six nails	Sheds rather than lifts
Salt air	Unaffected	Needs Galvalume or aluminium
Hail	Bruising, granule loss	Cosmetic denting
Heat	Absorbs; ages from below	Reflective coatings available
Repairability	Easy, cheap, matching fades	Harder; profiles discontinue
Insurance treatment	Standard	Often discounted

Where metal genuinely wins

Longevity. Forty years against twenty-odd is not a marginal difference; it is one roof instead of two, plus avoiding a second tear-off and a second disruption.

Wind. A standing-seam panel is continuous from eave to ridge and clipped down its length. There is no tab for wind to catch. Shingles perform well when fastened correctly, but they perform by resisting uplift at every individual piece, which is a different proposition.

Heat. A reflective coated metal roof rejects solar gain that a dark asphalt roof absorbs and passes into the roof space. In a Mississippi summer that is a genuine difference to the rooms below, and it is also why shingles here fail early — they cook from underneath.

Insurance. Many carriers writing wind cover on this coast discount for metal. Where your wind premium is most of your bill, that compounds meaningfully over decades.

Where shingle genuinely wins

Up-front cost. Roughly half. If you are selling within a decade, the long-run arithmetic never arrives and you have spent the difference for somebody else's benefit.

Repairability. A damaged shingle is replaced by anyone, cheaply, in an hour. A damaged metal panel may be a discontinued profile, and replacing one panel in the middle of a run is genuine work.

Hail, in a specific sense. Hail dents metal, and the denting is usually cosmetic — the roof keeps working — but insurers treat cosmetic damage inconsistently and some policies exclude it outright. Hail damages shingles functionally, which paradoxically makes it easier to claim for.

Finding installers. Every roofer on this coast fits shingle well. Standing seam is a narrower skill set, and a badly detailed metal roof is worse than a good shingle one.

Where exposed-fastener metal sits

Between the two, and frequently misunderstood. It costs a little more than shingle and considerably less than standing seam, and its service life is governed by the neoprene washers under the screw heads — around fifteen years in this sun and salt before a fastener campaign at $2,400 to $5,200. Budgeted for, it is good value. Assumed to be a forty-year roof, it disappoints.

How to decide

Selling within ten years: shingle, and keep the difference.
Staying twenty or more: metal is competitive before the insurance discount and ahead of it after.
Beachfront or heavily exposed: metal, with aluminium or Galvalume panels and matched fixings.
Budget is the binding constraint: shingle done properly beats metal done cheaply, every time.
Already rebuilt once after a storm: most people in that position choose metal, and Pass Christian is full of them.

Whichever you choose, the FORTIFIED detailing underneath works with both, and it is the part that decides what happens when the covering is tested.

Common questions

Which is better for hurricanes?

Standing-seam metal, by a reasonable margin, because the panel is continuous and clipped rather than relying on each piece resisting uplift. That said, a correctly fastened Class H shingle roof with six nails and proper edge detail performs well. The deck underneath matters more than either — which is the FORTIFIED argument.

Will metal really cut my insurance?

Often on this coast, because carriers rate wind performance heavily here and the wind portion is most of the premium. The size varies by carrier and it is not universal. Ring and ask for your specific figure before deciding, because a substantial discount changes which option is actually cheaper over time.

Does hail ruin a metal roof?

It dents it, usually cosmetically — the roof continues working. The complication is insurance: some policies exclude cosmetic damage outright, and carriers treat it inconsistently. On shingle, hail causes functional damage, which is less pleasant to look at in a different way but easier to claim for.

Is metal worth it on a house I will sell soon?

Generally not. The economics of metal are entirely in the long run, and if you sell in five years you have paid roughly double for a benefit the next owner collects. It may add something at resale, but rarely the difference. A good shingle roof is the better spend there.

What about cost over forty years?

Roughly: shingle at $15,000 replaced twice is $30,000 plus two lots of disruption, against standing seam at around $29,000 once, before any insurance discount. That is close enough that the decision turns on how long you are staying and how exposed the house is rather than on the arithmetic alone.
