The service area sits in a cold-moderate climate band, which matters more for rollers than most people expect. It's not the cold itself - it's the swing. Steel rollers contract in winter and expand in summer, and the grease packed into the bearing stiffens when the temperature drops fast overnight. That stiff grease is what you hear as the morning squeal, and over a few seasons it's also what cracks a roller's axle pin.
Because Priceville's housing stock skews to 2004 and later, most doors out here are still on their original rollers, not a second or third replacement set like you'd find on a 1989-built house back in Athens. That means the rollers we're pulling off Priceville doors have usually logged two decades of exactly that freeze-thaw cycle without ever being serviced, and when they fail they tend to fail as a set - four or five going within a season of each other - rather than one at a time.
We don't see much roller failure here from humidity or salt, the way you might near a coastline. It's almost entirely mechanical fatigue from cold-weather cycling plus two decades of zero lubrication.
