Across the 30 named areas we work in, most houses were built between 1947 and 1987, with the typical home dating to around 1964. That one fact drives most of what we see: original torsion hardware from the 1960s and 70s, steel sectional doors nearing the end of their spring life, and openers old enough that replacement parts are getting harder to source. The mild temperate climate here means it's not freeze-thaw cracking damage - it's cycle fatigue and sun-dried weatherstripping.
