I would give this a negative 10 .  Instructions were the worst I have ever seen.  Example. Putting on the roof instruction does not tell you to overhang the pieces so everything we did we always had to take back off and redo. Because of the bad instructions. I mean every step. The metal is super thin. It bends easy. Hail I think would go thru it.  You need to install where you want it .  Vent did not have screen on them so wasp could get inside easily. When I  back out a screw because of the instructions. The screw would strip out. The way the roof is designed ,if you live in the Midwest the roof will glog with the leaves and maple tree helicopters seeds.
