Most of the housing across this service area was built between 1976 and 2015, with the heaviest concentration going up in the 1980s and 90s. That matters for cables specifically: builder-grade galvanized cable from that era has a service life, and a lot of homes are now sitting on original hardware that's thirty-plus years old and was never upgraded when the opener got swapped out.
The climate here runs in the moderate heat band rather than the deep freeze-thaw cycles you'd get farther north, so cables don't typically snap from cold brittleness. What gets them instead is UV exposure on an uninsulated garage, humidity swings through the year, and plain fatigue from repeated wrapping and unwrapping on the drum, thousands of cycles a year on a door used daily. That shows up as fraying near the bottom fixture first, then at the drum, long before a full snap.
With 68,630 owner-occupied houses across the area sitting on roughly the same two decades of construction, we see the same failure pattern repeat subdivision by subdivision - it's not random, it's the stock aging out at the same rate it went in.
