The climate here is classed cold and severe, and that matters more to a garage door than most homeowners expect. A steel panel contracts in a hard freeze, and on a door that's been sitting since the 1960s or 70s, the panel seams and the spring's coil tension were never built with today's temperature swings in mind. Cold makes grease on an old roller stiffen up, which raises the load on the opener's gear every single cycle until the gear strips. We see the same pattern across the areas we run calls in near Berea, Lancaster, Irvine, and Winchester - older housing stock meeting a cold winter is what generates the bulk of midwinter service calls, not accidents or misuse. Attached garages built in that same era were rarely insulated at the door, so when a seal fails, the first symptom homeowners notice isn't the door itself - it's a cold wall inside the house. That's usually how a worn bottom seal gets found: not by looking at the garage, but by someone complaining the laundry room is freezing.
