Most calls fall into a short list: a broken torsion or extension spring, a cable that's jumped the drum, rollers worn enough that the door shudders on the track, an opener that runs but won't lift, or a panel dented past the point of squaring up. Winters here aren't severe, but we're in a cold-moderate band, and the swing between a humid summer and a cold snap is enough to work on wood panels, loosen hardware, and stiffen grease in older openers that haven't been serviced in a while. None of that needs a specific weather event to explain it - it's just what sitting hardware does over a few decades. One honest limit: if a door is old enough and far enough gone that the track, spring system, and panels all need work at once, replacing it is usually cheaper than chasing repairs one at a time, and we'll tell you that instead of running up a repair bill that doesn't make sense.
