Most homes in Finley went up around 1983, which puts the housing stock squarely in the same era as a lot of the wider service area - doors and track hardware from the early-to-mid 1980s, often with the original rollers and sometimes the original track still in place. Steel rollers on steel track, forty years on, wear unevenly, and an unevenly worn roller is one of the more common reasons a door jumps its track rather than rolling smoothly through it. The region sits in a cold-moderate climate band, and that matters here specifically because track brackets anchored into a garage wall can loosen slightly as temperatures swing through the year, shifting alignment just enough that a roller catches an edge instead of riding inside the track. Combine 1983-era hardware with a bracket that's drifted a few millimeters and you get exactly the kind of off-track failure that shows up as a door stuck half-open, hanging at an angle, or grinding against the frame. It's not a dramatic failure - usually just years of small wear finally meeting one bad moment.
