Housing across these seven areas mostly dates from 1967 to 2003, with the middle of that range - the 1980s and 90s - being where most of the stock sits. That matters because a door and opener installed during that build wave is now thirty-plus years old even in the newer pockets, and the springs, cables, and rollers from that era are well past their rated cycle count whether or not anyone's noticed yet.
Winters here sit in the severe end of the cold climate band, and that's hard on exactly the parts that are already tired: steel torsion springs lose tension faster in deep cold, nylon rollers from that period crack rather than just wearing down, and track brackets that have loosened over three decades let ice and condensation work into the hardware instead of shedding it. On the newer end of that 1967-2003 range you'll see more of the aluminum-track, chain-drive openers common to late-90s construction, which fail differently - usually the drive gear or the logic board before the door hardware itself. Either way, the fix starts with knowing which era of door you're actually standing in front of, not guessing.
