Most of the houses we get called to sit in that 1956-1979 build window, with a lot of them dating right around 1970. Doors from that era, or doors that replaced them decades ago on the original track spacing, were set up for lighter panels and simpler roller hardware. Track brackets on these older openings are often original or close to it, and they were never designed for today's heavier insulated doors bolted onto them later.
Cold is the other half of it. Ashland sits in a severe cold climate band, and steel track contracts in hard freezes. A track that's already got a slightly loose lag bolt from forty-plus years of settling will flex more in January than it does in July, and that's usually the point where a door jumps its rollers. We see the off-track calls cluster hard in the coldest stretches of winter for exactly this reason - it's not coincidence, it's metal doing what metal does at temperature.
Add in a driveway that's iced and scraped a dozen times a season, throwing salt and grit up into the track, and you've got rollers grinding instead of rolling. Combine an old bracket, a cold snap, and gritty rollers, and the door doesn't slide off track gently - it jumps.
