The biggest factor is age of hardware. With housing across this service area built anywhere from 1943 to 2011 and a heavy concentration in 1960s-70s construction, a large share of doors are still running on the original track, brackets, and rollers from whatever build era put them in. Steel track flexes and brackets back out of framing slowly over decades; a door that's run fine for years can come off track the first time a roller finally gives out from wear rather than from any single event.
The second factor is the cold. Cedar Rapids sits in a moderate-cold climate band, and that matters for garage doors because lubricant stiffens, steel contracts slightly, and rollers that were already marginal bind up instead of rolling smooth through a cycle. A roller that drags instead of rolling is a roller that's more likely to ride up out of the track under spring tension rather than track with it.
Put those two together - fifty-to-eighty-year-old hardware on a lot of area homes, and winters that make tired rollers worse - and off-track calls cluster hardest on older houses once the weather turns. Newer builds in the area see it far less, mostly from a bent track after something hit the door rather than wear.
