Most houses in Damascus went up around 1978, which puts the original garage door on a lot of them squarely in the single-layer steel era: a thin galvanized skin, no foam core, riveted to a frame that was never meant to stop heat or sound. Standard width back then was usually the 16-foot double or the 9-foot single, both on steel tracks with rollers that were fine for the first fifteen years and have been marginal ever since. These doors aren't failing because anyone did something wrong. They're failing because steel panels from the late 1970s weren't built with insulation in mind, and forty-plus years of expansion and contraction works the seams, the hinges, and the roller brackets loose. Add in the area's cold-moderate winters and that uninsulated panel becomes the single largest heat leak most of these garages have. We see the same pattern across a lot of the 1964-2006 housing stock we work on from Tualatin, but Damascus's own build years sit a touch older than the area median, so the fatigue tends to show up sooner and more consistently than it does in the newer subdivisions closer to town.
