What Causes It Around Here
Pueblo West is a different housing stock than the city it borders. Most of Pueblo proper is still running doors on hardware from the 1960s and 70s, but out here the build-out happened later, with most houses dating to around 1999. That matters for an off-track call because you're not usually looking at forty years of rust and sag - you're looking at a track system from a single-phase subdivision build, often installed fast and to minimum spec.
A track that was never shimmed quite plumb on day one doesn't show it for years, until a roller finally walks off the lip.\n\nThe other piece is the cold. This area sits in the same severe winter climate band as the rest of the county, and track trouble doesn't wait for a big storm to show up. A track that's even a little out of alignment collects ice at the bottom bracket, and that ice is enough to force a roller off the rail on the next close cycle.
Wind load matters too - a door that's slightly bowed from age or a hard stop will walk off track faster once the cold stiffens the rollers and the nylon gets brittle. Combine a production-build track with a cold snap and that's most of what we see out here.
