Bradenton sits in a mild temperate band - no hard freeze-thaw cycle to crack panels the way it does further north - but that same mild, humid air works steel and hardware differently over time. On homes from the 1964-2012 build range, the failure we see most is corrosion at the bottom rollers and track brackets, not warping from cold. Combine that with 63,634 owner-occupied houses across a service area built mostly in one long stretch of decades, and you get a lot of doors reaching the same age-related failure point around the same time, regardless of which of the 32 neighborhoods they sit in. It's less a weather event and more a slow, steady wear pattern from year-round humidity on original hardware.
