I am contemplating predrilling my corrugated zincalume roofing for my shed (I have already marked them up). I note that most people on this post say don't do it. The roof measures only 900 x 1500 mm (see My First Shed for pictures) and I cannot see why predrilling would be an issue - I have measured the rafters and the battens and the measurements are consistent. I am assuming it is only an issue on a large roof where it may not be totally square? Can someone please enlighten me?
Some other questions...
What is better to use - roofing screws or nails?
What corrugation spacing for the fixings - every third or fourth corrugation?
