I'm not looking forward to trying to fix it. I'm hoping that screwing in braces will do the trick.Amen to that! Same happened to me with the last big pen I started last year. I was able to roof half of it properly. The other side got tarps. Everything got pulled inward from the pressure exerted by the tarps. When the tarps came down, I had to hook a 2” ratchet strap to a tree and pull everything back right. I had to notch every ceiling joist to hold the front and back apart at the right distance.
