Yea I have a template for the top made from torch down roofing

. Its white metal, ah no I can't do the turn in my machines so its notching and bending by hand if we go this route. Good news we will be doing this in 4' pieces! If we had done the 10' ones we would have had a regular cleat reciever kicked at 45 degrees. I will prpbably never see the job so pics are doubtful. Thanks for the help.
Oh remember THAT GUY...Our That guy says the wall is PERFECT! and that his template is EXACTLY the same no matter which side is up or down
