The most common issue we see on installs out this way isn't rot or a rusted track, it's an opener that outlived its own gears while the door itself still looks fine, so homeowners assume the door is the problem when it's really the mismatch between an aging opener and a heavier replacement door. Cold-climate swings in this part of Washington also stiffen up nylon rollers and dry out old lubrication faster than most people expect, even on a door that's only 15 to 20 years old, so a new install is a good time to swap roller type, not just the panel.
A second failure point: undersized torsion springs. Builders in the 1990s and early 2000s sometimes speced the lightest spring that would pass inspection, not the one that matched the actual door weight years later when insulation or glass panels got added. If you're putting in a heavier insulated door as an upgrade, the old spring almost never carries it safely, and that's not a corner we'll cut.
