Oak Point's housing is young by garage-door standards - most of it went up after 2007, which means the original steel track and nylon roller hardware on these doors is now into its second decade of daily use. That's old enough for roller wheels to flatten and track brackets to loosen from vibration, but the houses aren't old enough yet for most owners to have replaced that hardware once already, the way you'd see in a neighborhood with 1980s stock.
With around 2,035 households in the area, that's a lot of doors built to the same builder spec in a tight window, which is also why the failure pattern repeats - a bumped bumper, a kid's bike against the bottom panel, or a roller that finally gives out after years of running dry without lubrication. The region's moderate heat band doesn't punish these doors the way extreme cold or humidity swings would elsewhere; most of what we see here is wear and impact, not weather damage to the hardware itself.
