Metal roofing is the fastest-growing choice in coastal Florida, and it drags a wagon of 1970s myths behind it. Let's retire the big five — and be honest about the real trade-offs.
Myth 1: 'It's loud when it rains'
That's a barn roof — metal over open framing. A residential metal roof installs over solid decking and underlayment, with insulation and drywall below. In practice it's comparable to shingles in a downpour; many owners can't tell the difference from inside.
Myth 2: 'It attracts lightning'
Lightning strikes the tallest path to ground, not the most conductive roof. Metal doesn't increase strike probability — and if a strike happens, a non-combustible metal roof is actually the one you'd want.
Myth 3: 'It'll rust out near the beach'
Modern aluminum and coated-steel systems are engineered for coastal exposure — aluminum in particular shrugs at salt air, which is why you see it on beachfront homes from Clearwater Beach to St. Pete Beach. Spec the right metal for your distance to salt water and this is a solved problem.
Myth 4: 'It makes the house hotter'
Backwards. Reflective metal finishes bounce solar radiation that shingles absorb, and above-sheathing ventilation designs shed heat further. Metal typically REDUCES summer cooling load in Florida.
Myth 5: 'It's not worth the premium'
Metal costs meaningfully more upfront than architectural shingle. But run the Florida math: 40-50+ year service life versus 15-20, superior wind performance, insurance conversations that get easier rather than harder with age, and cooling savings every summer. For owners planning to stay — or to sell to buyers who ask about roofs, which is now everyone — metal frequently wins the decade math.
Who shouldn't buy it
Short-horizon owners on a tight budget: a quality shingle system protects the house for less cash today, and we'll tell you that plainly when it's the better fit.
