Bradenton sits in a mild, temperate band - no hard freezes, no deep winter to seize up hardware the way colder regions get. That works in your favor on some fronts, but it doesn't spare the door from Florida's other habit: humidity and salt-tinged air that corrode springs, hinges, and bottom brackets faster than a dry climate would, especially on the older end of that 1964-2012 build range. A torsion spring rated for a certain number of cycles wears out on schedule regardless of weather, but the corrosion on hardware near the ground - tracks, rollers, the bottom seal retainer - shows up sooner here than it would somewhere drier. Combine that with houses now sitting 50 to 60 years past their original install and you get the pattern we actually see on service calls: rust-seized rollers, pitted torsion shafts, and openers whose logic boards have simply outlasted their expected life. It's steady wear from a steady climate, not a single storm event.
