Lolo's housing stock centers on a median build year of 1995, which puts a lot of these garage doors in the same window as the broader service area's 1976-2013 construction range. Doors going up in that mid-90s stretch typically shipped with steel torsion springs rated for a set number of open-close cycles - often somewhere around 10,000. At average household use, that's a spring with maybe 10 to 15 years in it before fatigue sets in, and plenty of Lolo doors are now two or even three springs past the original.
Cold is the other half of it. This area sits in a severe cold climate band, and steel springs lose some flexibility as temperatures drop - a spring that's already near the end of its cycle count is more likely to snap on a hard winter morning than in July. That's not unique to any one house; it's just physics meeting a door that's been doing its job since the Clinton administration.
