The Puget Sound area sits in a cold-moderate climate band, and that matters more for garage doors than most homeowners assume. It's not deep-freeze cold, but the swing between damp fall mornings and cold snaps is enough to stiffen lubricant in older rollers and hinges, and enough moisture over a winter to start rust on cable and hardware that isn't sealed well.
Covington's stock, built mostly around the 1990s, doesn't have the insulation upgrades or sealed bottom brackets that later code cycles required. That means more of these doors run bare steel tracks and older weatherstripping that's compressed flat after 30 years, letting cold air and moisture into the garage in a way a newer door wouldn't.
Compare that to some of the older pockets in the wider area, where houses date closer to the early 1980s - those doors have already been through one or two full replacement cycles. Covington's 1994-era doors are often still on original hardware, which is why the failures we see out here tend to be fatigue-related rather than the flat-out obsolete-parts problems you get with older stock.
