This area sits in a cold climate zone with severe winters, and that's a real factor in roller wear. Steel rollers pit and rust faster when they cycle through freeze and thaw all winter, especially if the garage isn't heated. Nylon rollers hold up better in the cold generally, but even they get brittle with enough winters behind them and can crack at the hub rather than wearing down gradually.
With only 762 households in Ashford, this isn't a place where a bad batch of rollers fails across a whole subdivision at once - it's scattered, tied more to when each house was built than to any one shared cause. Given a median household income of $88,879, most owners here choose to replace the rollers rather than the whole door when the hardware starts failing but the panels themselves are still sound. That's usually the right call: rollers are a wear part, and a door with solid panels doesn't need to go in the dumpster because the wheels are shot.
