What we see on a typical service call
Most calls about door material start the same way: a homeowner wants to know why their door looks rough after only a few years. On older wood doors, we find swollen bottom rails and peeling paint where sun and rain have worked the panel for seasons. On steel doors, it's usually a dent from hail or a trash can, with rust creeping out from the scratch. On cheaper aluminum doors, the whole panel is oil-canned and wavy from heat and wind pressure. Fiberglass and composite doors tend to hold their shape, but we still check the skin for sun-bleaching and the core for moisture if a seal has failed. The material someone chose years ago is still shaping the repair calls we run today.
Steel
Steel is the most common choice in this area, and for good reason. It resists warping in long hot summers, shrugs off wind-driven debris better than wood, and stands up reasonably well to hail if it's a thicker gauge with a quality finish. The trade-off is that steel dents, and once the galvanized coating is scratched, rust can start, especially after a sudden severe storm leaves standing moisture on the panel. Insulated steel doors (steel skin over a foam core) also help even out the temperature swing in an attached garage during summer.
Wood
Wood looks great and can be refinished almost indefinitely, which appeals to homeowners who want a custom look on an older or high-end home. But wood is the highest-maintenance option in this climate. Sun exposure fades and dries the surface, hot-to-cold swings and occasional ice in the northern part of the state cause expansion and contraction, and any gap in the sealant lets moisture into the panel joints. If you choose wood, plan on repainting or restaining every couple of years and checking the bottom panel for rot after major storms.
Aluminum
Aluminum won't rust, which makes it appealing in humid stretches or for homes near sprinklers that spray the door. It's also lighter, which can be easier on an aging opener. The downside is that standard aluminum is soft - wind pressure and hail can dent or oil-can the panels, and once that happens the door rarely looks right again. Heavier-gauge aluminum performs better but costs more, narrowing the gap with steel.
Fiberglass
Fiberglass resists dents, won't rust, and holds paint well under constant sun, which makes it a strong option for south- and west-facing garages that take the worst of the afternoon heat. It can mimic a wood look without the maintenance. The trade-off is impact resistance in a different sense: a hard enough hit can crack the fiberglass skin rather than just dent it, and repairs usually mean panel replacement rather than a simple dent pull.
Composite
Composite doors blend a resin or wood-fiber skin over a steel or foam frame, aiming for wood's look with steel's durability. They resist moisture damage and insects better than real wood and handle temperature swings without warping. They cost more than basic steel but less than high-end solid wood, and for homeowners who want curb appeal without a repainting schedule, composite is worth a look.
Recommendation for typical homes here
For most homes in this area, an insulated steel door is the practical choice: it handles heat, hail, and wind better than aluminum, needs far less upkeep than wood, and costs less than fiberglass or composite. If your garage faces direct afternoon sun or you want a wood look without the maintenance, fiberglass or composite are worth the extra cost. Save solid wood for homes where the look matters more than low maintenance, and budget for regular refinishing.
