Housing across this service area was mostly built between 1958 and 2005, with the median build year landing around 1979, and most of the 31 named communities we work in are dominated by that same 1960s-70s stock. That matters for openers specifically: a huge share of the original or first-replacement units installed in these houses are now well past the age where circuit boards, capacitors, and drive gears start to go. Chain-drive openers from that era weren't built with today's sealed electronics, and twenty-plus years of garage heat does them no favors.
The mild temperate climate here doesn't bring the hard freezes that crack housings up north, but it does mean steady humidity and heat cycling in garages that often aren't insulated or conditioned at all. That's rough on circuit boards, on the little photo-eye sensors near the floor, and on the plastic gears inside the motor housing - they get brittle and strip teeth years before they would somewhere drier. We see a lot of failed logic boards and corroded sensor wiring for exactly this reason, more than we see broken springs or bent track in the same houses.
So the common failure here isn't storm damage. It's age and heat working on the same generation of hardware across tens of thousands of houses at once.
