Coastal Aluminum Metal Roofing

Steel roofs can rust in constant salt air, but aluminum roofs do not. That is exactly why, on homes near the ocean, we install marine-grade aluminum instead of steel. Aluminum will not rust no matter how much salt spray it takes, so the roof holds up for decades right on the water.

Aluminum is the better choice for a coastal home because salt air will eventually corrode even coated steel, while aluminum does not rust at all. Its concealed fasteners leave no exposed metal to corrode, and its Kynar 500 finish shrugs off sun and sea spray for decades. It outlasts tile, wood, and steel in a marine environment, which is why it is the roof of choice on beach and bluff homes. We match the metal to your location.

The finish is what shields the metal from salt and sun, so at the coast it matters nearly as much as the metal underneath. We coat every coastal roof in 70% Kynar 500, the premium PVDF finish that resists salt corrosion, fading, and chalking for decades, instead of the cheaper SMP paint that breaks down fast in a marine climate. It holds its color and its protection even under daily salt spray and full sun.

Aluminum roofing does not corrode the way steel does because aluminum forms its own thin, protective oxide layer that stops rust before it starts, even in constant salt spray. Finished in Kynar 500 and installed with corrosion-compatible clips and flashings, an aluminum roof stays sound for 50 years or more at the coast.

An aluminum roof lasts 50 years or more, even directly on the water. Because aluminum does not rust and its Kynar 500 finish resists salt, sun, and moisture, it holds up in the marine environment that wears out ordinary roofs. It is a pay-once roof for an oceanfront home.

We install heavy .032-inch and .040-inch aluminum, and the thickness matters because heavier aluminum stays flat and resists the rippling, denting, and oil-canning that thinner metal shows at the coast. Aluminum is measured in inches of thickness, not in gauge like steel, and these heavy thicknesses hold their shape against strong coastal wind and give the finished roof its crisp, clean lines. We match the exact thickness to your roof and its exposure.

Yes, a standing seam aluminum roof is built for coastal wind. We lock each panel to the deck with double clips and two screws per clip, spaced tighter at the eaves, rakes, and ridges where uplift is strongest, and there are no loose shingles or exposed edges for the wind to catch. It is one of the best roofs for a home that takes ocean storms.

We treat every field-cut edge and use only corrosion-compatible fasteners, clips, and flashings, so no vulnerable metal is left exposed to salt air. Mixing the wrong metals causes galvanic corrosion, which is how a sloppy coastal install fails early. Matching every part to the aluminum is the detail most roofers miss, and we never do.

Yes, and a standing seam aluminum roof is an excellent base for solar. The panels clamp onto the raised seams with no holes drilled through the roof, so there are no penetrations to corrode or leak in salt air. We hold the full C-10 electrical license, so we install both the roof and the solar for you.

No, it is not a good idea because a standing seam roof needs a solid, sound surface so the clips anchor the panels securely to the roof deck. Having to nail through existing tiles or asphalt compromises that secure connection, making the roof vulnerable to leaks, embers getting inside, and weakening the system during a wind storm.
