Most of the housing across this service area went up between 1972 and 2005, with a heavy run of construction through the 1980s and 90s and a median build year sitting around 1998. That matters for cables because the lifting cables on a torsion system aren't designed to last forever - they're a wear part, same as a roller or a cable drum bearing. A door built in that 1980s-90s wave is now old enough that its original factory cable has seen three or four decades of daily cycling. Add in a climate band that's cold and moderate rather than mild, and you get repeated freeze-thaw swings through the winter months. Cold makes galvanized steel strands stiffer and more prone to fraying where they wrap the drum, especially on a door that's slightly out of adjustment already. We see broken cables most on original hardware from that era - not because anyone did anything wrong, but because the part has simply aged out. A door that's 25-plus years old with its original cables is closer to the end of that cable's working life than the beginning, regardless of how well it's been maintained.
