Most of the housing across this service area went up between 1968 and 2000, with the bulk of it dating to the 1980s and 90s. That's the exact window when steel aircraft cable and galvanized drums were standard on residential doors, and a lot of that original hardware is still in garages today - thirty-plus years of open-close cycles on the same cable.
Cold, damp winters speed that process up. Repeated freeze-thaw cycles work moisture into the cable strands at the drum end, where galvanizing wears thin first from friction. Once rust gets a foothold inside the strands, the cable loses tensile strength from the inside out, long before it looks bad from the outside. That's different from a dry climate, where cables mostly fail from UV and heat cracking the outer strands you can actually see.
So in a service area built mostly in the 80s and 90s and sitting in a cold, wet climate band, the typical failure here is a cable that rusts through at the drum groove and lets go with no warning, rather than one that frays visibly over months. Owners are often surprised because the cable looked fine the week before.
