Most of the housing across this service area went up between 1953 and 2014, with a median build year around 1995 and a heavy concentration of 1980s and 90s construction. That era of garage door hardware is standard-duty galvanized cable on steel drums, built to a normal service life, not to the climate load this area actually sees. This region sits in a severe-heat band, and heat is hard on cable in two specific ways: it dries out the factory lubricant faster, leaving bare strands to rub against the drum groove, and the repeated expansion and contraction of the metal track and drum over daily heat cycles works the cable loose at the swage fitting where it's crimped. A cable rated for a decade in a mild climate often doesn't make it that long here. Add in 65,647 owner-occupied houses out of 114,987 households across the area, many still on original builder-grade hardware, and you get a predictable pattern: doors built in the mid-90s construction wave are now past the point where their original cables should still be trusted, and the summer heat is what finally finishes them off.
