A technician pulls up to a house a few blocks off Sebastian Blvd and already knows what he'll find before the owner says a word: bubbling paint along the bottom panel, a faint rust line where two sections meet, and a door that sticks every time the humidity spikes. The material the door is made of usually explains the whole call. Salt air, afternoon downpours, and wind-load requirements treat every garage door material differently, and picking the wrong one means fighting the same problem every year.
Steel
Steel is the standard choice for a reason. It's affordable, available in wind-rated options for storm season, and holds up to impact better than most alternatives. The trade-off is rust. Near the coast, salt in the air works into scratches, seams, and the bottom corners where water collects after a downpour. A factory-applied galvanized coating with a baked-on finish resists this far longer than a bargain-grade panel, and it's worth asking specifically for that spec rather than assuming all steel doors are equal.
Wood
Wood gives a look that steel and aluminum can't fully copy, and some homeowners want that on a front-facing garage. But humidity is wood's enemy. Panels swell in wet season and shrink in the dry stretch, which leads to sticking, misaligned tracks, and cracked seams at the joints. Wood also needs re-sealing on a schedule that most people underestimate. In a climate with this much moisture and sun exposure, wood is a high-maintenance choice, not a set-and-forget one.
Aluminum
Aluminum won't rust, which makes it appealing close to the water. It's lighter than steel, which is a plus for opener strain, but that same lightness means it dents and oil-cans (that rippled, wavy look) more easily under wind pressure or a stray basketball. For a storm-prone area, the lower durability under high wind load is the real concern, so if aluminum is chosen, it should carry a wind-rated frame and bracing package, not just a standard residential panel.
Fiberglass
Fiberglass resists rust completely and handles salt air better than almost anything else on this list, which makes it a strong pick for homes closer to the coast. It can be molded to mimic wood grain, so it gives some of that look without the swelling problem. The downside is impact resistance. Fiberglass can crack or shatter in a hard hit, whether that's storm debris or a backed-into-corner mistake, and repairs are usually panel replacement rather than a simple patch.
Composite
Composite doors are built to solve the wood-look, no-rot problem directly. They don't swell, don't need re-sealing on a tight schedule, and hold paint and finish well in humid, salty air. The trade-off is cost. Composite doors typically sit at the higher end of residential pricing, and installation requires more care to get the wind-rated hardware matched correctly.
What Fits Most Homes Here
For a typical home in this area, factory-finished steel with a wind-rated certification is the most practical balance of cost, durability, and storm readiness. Homes within a mile or two of the water, where salt air is more aggressive, often do better with fiberglass or composite despite the higher upfront cost, simply because the maintenance savings add up over several hurricane seasons. Wood works best as an accent, not a full garage door, in this climate.
