Outdoor Roofing
Unfortunately, I’m no roofing expert. However, it is for light roofing and has worked fine for holding PVC roofing sheets over a run I made for my rabbits. The grey parts represent the size of the run. The dark red represents new cross braces for the run, which are pocket screwed for flush convenience on the inside. The pink/bright red is the three frames I’d need to assemble out of 6 pieces of CLS timber. I then drew a line on the angled pieces that determined the angle itself without needing potentially Pythagoras’ theorem. What could be better is bracing them in between instead of relying on three screw points under the frame itself. I am yet to post what it looks like.
