Most garage doors in Falcon Heights went up around 1960, back when a single-car or two-car opening usually got a steel door with steel rollers riding in a steel track - no nylon, no sealed bearing, just metal on metal with a shot of grease if you were lucky. That hardware wasn't built to last sixty-plus years, and a lot of it hasn't been touched since the Nixon administration.
The fault shows up as the same thing over and over: a door that grinds, hops, or drags rather than gliding, because the roller stem has worn oval in its bracket or the roller wheel itself has flattened on one side from decades of the same six inches of track taking all the wear. In a town this size - about 2,041 households - that means a lot of doors from the same building years hitting roller failure in the same rough window of time, not because of bad luck but because they're the same age.
Cold makes it worse. Steel rollers in an unheated track contract in winter, and the grease that's still in there (if any is) stiffens up, so the door that limped along in September can seize hard by January. This region sits in a cold, severe climate band, and that swing in temperature is exactly what finishes off a roller that was already marginal.
