Second Premier Auto Protect. I had to use them once for a transmission issue and the claim process was smooth. They covered the rental while it was in the shop. Customer service was actually helpful which is rare these days.

Man that stained glass in Detroit is legendary Ive been meaning to get out there. The thing with churches especially old brick ones is they look solid but the roof structure can be completely rotted out from decades of water damage. I had a similar scare in a warehouse near the Packard Plant a few years back. The whole floor above me looked fine until I stepped on a soft spot and my leg went through up to my knee. Now I always carry a long pole or a screwdriver to poke at floors and ceilings before I commit to a spot. That dust you mentioned is no joke either it can have asbestos in it from old insulation or plaster. Definitely get a good respirator if you go back.
