We had a storm last Saturday that peeled a metal roof off one building
(like a sardine can). The ones with asphalt shingles has no damage at
all. In east TN. A metal roof would be more expensive to repair than
a shingle roof.

I'm on the edge of the Cumberland Plateau and we had that same storm. As I
mentioned, the edges must be securely fastened, must be better than the
professional will do. The professional installers will meet the code, but
here with hurricane-like winds and tornados in the area which spawn damaging
winds for several miles around, one must do better than the code. The north
side of my house overlooks a 300 ft drop so it is exposed. Last week's storm
came straight out of the north and my roof didn't have any damage. Trees and
power lines came down but the roof is ok. I agree, once the edge of a metal
roof goes, it'll peel like a sardine can. The edge is the key. If a pro
installs it, you'd better go up there afterward and put more screws in.
