Gf mom has an Amish farrier from up around Indee somewhere. He also did roofs with his brothers, had a supplier for the steel up there somewhere too. So we had a steel roof on the house within 40 days post-derecho.If you were able to find metal roofing material after the derecho, you are fortunate. I wanted to go that route, but materials were months out at the time with every place I checked.
Which was good, as we had a ~70 yo maple fall on the house. 12 holes in the roof, lots of water ingress, completely demolished the 3 season porch on back of house. I spent a lot of time on the roof with tarps and in the attic with buckets and still had water coming in. Thankfully it didn't rain much during that time.
