Yeap, just another roof seam that requires the usual inspection and care.
Cutting a big hole in the roof to replace a fridge is about the hardest method possible and I doubt if anybody would do that unless there was no door or window large enough (and that seems unlikely). Maybe it was leaking around the roof vent and was damaged enough to require replacement on that section.
