Two things wear rollers out faster in West Linn than they would somewhere drier or newer-built. First, the age of the stock - a door built around 1988 has had over three decades of cycles on hardware that wasn't designed to last that long in the first place. Second, the climate: this area sits in a cold, moderate band where damp winters swell wood jambs and tighten the clearance the rollers ride in, which loads steel rollers harder every time the door runs.
With close to 9,919 households in West Linn, a fair number of them are still running that original 1988-era hardware, which means a roller failing now isn't early - it's about on schedule. We don't see this as often on houses built after 2000 with newer nylon rollers from the factory, which hold up better in this same climate. If your door is from that later wave and a roller's already failed, that's usually a sign something else - an opener pulling crooked, a bent track - is working against it.
