Portico Problem # 2 Let's count the other things that were wrong with our old portico.This is a bad picture, but this is a closeup of the standing seam that was in the middle of the left side of the portico. The seam runs vertically down the middle of the picture and is actually shaped like an upside-down V - the point is the line you see and the edges go down - you can see the left edge terminating in the white area and the right edge connects to the rest of the pan. Note that this seam was not double folded - it was simply folded over once. Since there were no cleats holding the seams down, you could actually lift this pan off the other one with your hands. Eric said it is amazing that the roof hadn't blown off.
