This area runs roughly 15,816 households, about 12,629 of them owner-occupied, and the bulk of those houses were built in the 1980s and 90s stretch of the 1976-2012 window. That generation of garage doors almost always shipped with steel rollers on steel stems, not the sealed nylon rollers you'd spec on a new install today. Steel-on-steel wears a groove into itself over time, and once that groove gets rough, the roller doesn't glide through the track - it drags, chatters, and eventually binds.
The climate here is cold-moderate, which means real temperature swings through the winter months. Metal contracts in the cold, and a track that's a fraction tighter at 6am than it was at 2pm the day before is enough to turn a roller that's merely worn into one that's actively grinding. That combination - original-era steel rollers plus a track that tightens seasonally - is why roller failure shows up so often in houses from this build era specifically, rather than being spread evenly across every house regardless of age.
