With a median build year of 1987, the failures we see most in University Park trace back to age rather than weather extremes - the climate here runs moderate on heat, so we're not chasing the kind of thermal expansion issues that show up in harsher bands. What we do see is fatigue: springs that have done their 10,000-plus cycles and are past due, rollers worn down to bare metal after decades of use, and openers original to the house that are simply at the end of their working life. Track misalignment shows up more often here too, usually from small settling over 35+ years rather than a single event. It's a different failure profile than a 2005-built house a few miles away, where the more common call is a first or second spring replacement rather than a fourth.
