Holly Springs sits about 19 miles out from our shop in Johns Creek, and the drive matters less than what's waiting at the end of it. This isn't a town of aging one-piece doors on side-mounted torsion springs. Most of the housing here went up after 2007, which means builder-grade doors with stock rollers - usually the cheap 7-ball nylon kind that ship standard on new construction to keep costs down at closing. Those rollers aren't bad, but they're not built to last the life of the door either.
In a moderate cold climate like this one, plastic rollers get brittle faster than people expect. A roller that's fine in August can start chipping or cracking by February, and once the nylon sheath splits, the steel ball bearing inside grinds straight against the track. You hear it before you see it - a rhythmic clunk or scrape every time the door cycles. On newer builds especially, we're often swapping out the original builder rollers for sealed steel ones before the door's even old enough to need anything else.
