With a median household income of $164,459, Highland Village has more two-and-three-car garages with heavier insulated doors than a town built mostly on single-car openings. Heavier doors put more load on the track brackets, and when a bracket works loose from years of that extra weight, the door walks off the rail instead of snapping off it cleanly. The area's housing dates mostly from the early 1990s onward, so track degradation here tends to be wear-based - stretched hinges, worn rollers, brackets backing out of the jamb - rather than storm damage. The regional climate is moderate on the heat side, so we don't see the track-warping from extreme swings that shows up in harsher climate zones; most off-track calls here trace back to a bump from a car or a bracket that finally gave out, not weather.
