The housing stock across this service area runs mostly 1949 to 1993, with the bulk built in the 1960s and 70s - that's the era that standardized the single torsion spring over a single garage door, which is exactly the setup with no backup when the spring finally lets go. Doors and openers from that build wave are also old enough now that steel fatigue, not one bad day, is usually the real cause.
The cold-moderate climate band here adds a second layer to it. It's not cold enough to crack concrete slabs the way a harsher climate does, but it's consistent enough that grease thickens in the rollers and tracks every winter, torsion springs lose a little tension with each freeze-thaw cycle, and openers drift out of calibration as the door's resistance changes with the temperature. Put an aging spring on an aging track through a winter like that, and the failure isn't random - it's close to scheduled. That combination, old hardware plus a climate that works on it every year, is why we see more spring and track calls here than pure opener-electronics calls.
