Most of the housing across Greensboro and the surrounding communities we serve went up between 1968 and 2002, with the bulk clustered in the 1980s and 90s. That generation of garage door hardware leaned on steel rollers riding in galvanized track, held by brackets lag-bolted into door framing that's now three to five decades old. Wood framing shrinks and shifts over that span, brackets loosen a sixteenth of an inch at a time, and eventually a roller has just enough play to walk off the rail on a hard stop or a gust of wind against the panel.
The climate here doesn't help. This area sits in a moderate-cold band, which means real freeze-thaw cycles through the winter months rather than a hard freeze that stays put. Track brackets expand and contract with that swing, grease in old rollers stiffens in cold snaps and lets go when it warms back up, and a door that was riding fine in October can start binding and jumping track by February. It's not dramatic weather, just repeated small stress on fasteners that were installed when Reagan was in office.
We see it most on doors that still have their original hardware from that build era. If your house falls in that window and nobody's touched the rollers or track brackets since, this is the kind of failure to expect eventually, not a fluke.
