Knightdale sits in the same cold-moderate climate band as the rest of the Triangle, which means real cold snaps a few times a winter, not the deep freeze you get further north. That matters here because 2006-era track hardware was typically installed without a lot of thought to lubrication intervals, and steel track contracts slightly in a hard cold snap. A track that was already a hair out of alignment from age or a bump will show it first on the coldest mornings of the year, when the metal is tightest and the roller has the least room to ride true.
With most of the housing stock here built in a tight window around the same year, we see the same failure pattern on a lot of these doors: original rollers, original track brackets, nineteen-plus years of cycling, and no history of adjustment. It's not a defect specific to any one builder - it's just what happens when a whole neighborhood's garage hardware ages out at the same time.
