Every roofing material will survive a mild climate. Ours is not a mild climate. Between named storms, spring hail, and four months a year where the attic runs hotter than the driveway, the Gulf Coast sorts roofing products faster than the warranty language suggests it will.
Architectural asphalt shingle is still the default for good reasons: it is the cheapest square footage, it is repairable in patches, and a quality laminate rated for high wind performs well when it is fastened correctly. That last clause carries most of the weight. Nail placement, nail count and a properly bonded sealant strip separate a roof that stays on from one that peels at the rake edge, and no warranty compensates for a rushed install.
Standing seam metal costs more up front and pays it back in lifespan and wind performance. Concealed fasteners mean nothing to work loose, panels shed water fast in a downpour, and a light-colored finish reflects enough heat to make a real difference in an unconditioned attic. It's the strongest choice near the water, and it is also the least forgiving of a sloppy installer, because a metal roof is a system of details rather than a field of overlapping pieces.
Flat and low-slope systems, TPO and modified bitumen, belong on the porch additions and light commercial buildings that need them, not on a pitched house. Where you do have them, drainage is everything: a flat roof that ponds water is a flat roof with a countdown on it.
Whatever goes on top, the parts you never see decide how long it lasts. Sound decking, ice-and-water membrane in the valleys and around every penetration, correct drip edge, and intake and exhaust ventilation that are actually balanced. A premium shingle over a badly ventilated attic will underperform a mid-grade shingle over a good one, every time.
