The housing stock in Shields centers on 1976, a few years past the 1970 median for the wider service area, which runs from 1952 up through 1994 construction. That means most garage doors here are original to a house built in the mid-to-late '70s, or a replacement installed on hardware sized for that era - narrower track, lighter roller stems, brackets that don't match what a big-box store sells off the shelf today.
The bigger driver of off-track failures, though, is the cold. This part of the state sits in a severe cold climate band, and that means real freeze-thaw cycling on anything metal sitting in an unheated garage. Condensation forms on the track overnight, freezes, and by morning a roller that used to glide is fighting a skin of ice. Force the opener through that and the roller jumps the channel instead of riding it. We see the same pattern on doors that look fine in July and start binding the second the first hard frost hits.
A bent track from a car bumper or a snowblower catching a corner does it too, but around here, ice inside the channel is the more common culprit than a one-time impact.
