Spring tension loss in freezes
In a lot of Spokane Valley garages, that's a torsion spring losing tension faster than it should, because the spring has been cycling through hard freezes for years. Homes here were mostly built between 1951 and 2008, with a lot of the stock dating to the 1960s and '70s across the valley's older pockets, and that generation of hardware was never rated for the cold snaps this area gets.
