The climate here sits in a cold, moderate band, and that matters more for a 1990s-built garage than people expect. Doors from this era are typically insulated steel with a foam core bonded between two skins. That construction holds up well early on, but after enough freeze-thaw cycles the foam can separate slightly from the steel, and once that happens the door panel flexes more than it should when the torsion spring pulls on it - which speeds up wear on a spring that was already approaching the end of its rated life.
With about 10,914 households in town, most built within a fairly narrow window, a hard cold snap tends to produce a run of similar failures in the same week rather than one-off calls spread evenly through the year - springs that were all installed around the same era reach the end of their cycle life around the same time, and cold temperatures make steel more brittle right when the spring is already stressed.
We can't do anything about the timing of a cold snap. What we can do is check spring cycle count and opener board condition together on a single visit, since on houses this age the two failures often show up close together.
