Quick answer
Rust starts at the bottom of the door, at fasteners and on spring wire. Rinse the door regularly, keep seals intact and specify galvanised or stainless hardware. Corroded structural parts need garage door repair.
Salt and humidity mean rust is a Florida certainty — the timeline is what you control.
