The median house in Brookhaven was built around 1992 - a good fifteen years newer than the 1978 median across the rest of the service area, where most stock dates to the 1960s and 70s. That gap matters more than it sounds like it should.
A door from the early 90s is old enough that the original opener is near or past its working life, but young enough that homeowners often assume it's "newer" and skip maintenance that a 60s-era door owner would already know to schedule. The failure we see most in Brookhaven isn't a rusted-out one-piece panel - it's a chain-drive opener with a logic board that's quietly dying, or a torsion spring that's done its 10,000 cycles right on schedule and nobody noticed the sag.
The cold-moderate climate here doesn't help those springs age gracefully either - freeze-thaw swings put extra load on hardware that's already near the end of its rated cycle count, whether the door is from 1965 or 1992.
