Germantown's service area runs across 45 named communities built mostly in the 1980s and 90s, with the overall housing stock spanning 1951 to 2015. That means a lot of doors in the area are aging out on a similar schedule - galvanized track that's pitted from twenty-plus winters, torsion springs rated for a lighter door than what's actually hanging on them, and panel steel that was never insulated to begin with. Add in the cold-severe climate band this area sits in, and that uninsulated steel does exactly what bare metal does in a hard freeze-thaw cycle: it contracts, flexes at the seams, and eventually warps enough that the door won't seal at the bottom. We see this pattern across the same build era in Clarksburg and Montgomery Village too, not just in Germantown proper, because the houses went up in the same construction wave. It's less about any one storm and more about decades of ordinary winter stress on doors that were built to a lower standard than what's sold today.
