Hello. I'll get on with this while I'm feeding my face, multitasking, I can chew while I type, ha ha. As you can see the roof is on. I have used the panels exactly as they were, didn't need to cut any off. There is a good overhang which is what I wanted. I had to move four of the support boards, I spaced them evenly across the top but they needed to be two for each panel with the outer ones being right on the edge. Each panel has two screws at each end holding it in place. Although it is pretty solid I might add some more. We have had a bit of wind, but I wouldn't want them to take off across the neighbours garden if it gets very blustery.
