A door built around 1993 was almost certainly installed with a torsion spring system and a chain or belt-drive opener that's since been swapped out at least once, maybe twice. The panels themselves hold up fine in this climate band - cold and severe, same as the rest of the Missoula area - but insulation specs from that era are thinner than what goes in today, so owners often notice the garage runs colder than they'd like, especially if it's attached to living space. We don't see much call for structural panel work out here; it's springs, cables, rollers, and openers reaching the end of their service life, plus the occasional sensor or track alignment issue after a winter of use. If a door out here needs real structural repair, it's more often storm or impact damage than age, since the hardware itself isn't old enough yet to be the main suspect.
