Homer's houses cluster tight around a 1974 median build year, which puts most garages in this town on hardware designed for a cold-but-not-brutal winter load - standard for the era, not built for the kind of severe cold swings this region actually gets. Steel contracts in deep cold, torsion springs lose a measurable amount of lift on the coldest mornings, and a door that worked fine in October can bind in January on the exact same spring.
The area sits in a severe cold climate band, and that matters more for garage doors than people expect - not because the door freezes shut, but because cold steel and cold lubricant change how much force an aging spring has left to give. A spring that's marginal in September can be the reason a door won't lift at all in a hard freeze.
Homer's smaller household count - 1,566 against the wider service area's 18,597 - means fewer of these doors have been touched or upgraded in the last decade simply because there are fewer of them to begin with. Original hardware sticks around longer where there's less turnover pushing replacement.
