A lot of the garage doors we work on sit on houses built between 1973 and 2012, with the heaviest concentration of stock going up in the 1980s and 90s across the area's older neighborhoods. Builder-grade doors from that period almost always shipped with plain steel rollers on steel stems, which was standard and fine hardware at the time but has had three or four decades of daily cycling to wear down.
Athens sits in a cold-moderate climate band, and that matters here specifically because steel contracts in cold weather, tightening the clearance between roller and stem and making a worn roller bind and grind harder on cold mornings than it does in summer. Owners often tell us the noise is worse in winter, and that's not imagination - it's the metal doing what metal does in the cold.
Add in that most of these doors cycle two to four times a day for a household, and a roller rated for a certain number of cycles simply runs out its service life. It's not a sign anything was installed wrong. It's a part with a lifespan, installed on a door that's been doing its job for a long time.
