On a house this age, the door usually doesn't fail quietly. It groans on the way up, or it slams the last six inches down because the spring can no longer carry its share of the weight. Some owners notice the opener straining - motor working louder than it used to, or reversing partway through a cycle. Others find the door simply won't move, stuck mid-track with a cable that's jumped the drum.
In Allouez specifically, because so much of the original 1969-era hardware is still in place, the failure tends to be age-related rather than damage-related. We don't see as many doors knocked off track by impact here as we see springs that have simply reached the end of their cycle count. That's a different diagnosis and a different fix than a dented panel or a bent track.
