John,how come your fasteners for the corrugated iron are in the troughs?Typically (here in oz) they go on the peaks.I'm really enjoying your journey.regards,Trev.
Trev good catch on the placements of the screws, here in Texas my whole barn roof is same material and all of the screws are on the peak as well. My steel house roof is different panel, and it is screwed down on the flat panels,, BUT with silicon and a rubber washer to seal against water.
I prefer to place the screws in the troughs because it goes much faster, and because my tin is slightly bent to conform to the radius - when you go through the peaks you have to be very carefull not to deform the corrugation. With my roofing being under stress due to the bending - it would be very difficult not to crush the peaks. I don't think there is any wrong way to do it but in my case it was the best way. http://www.mcelroymetal.com/elements/files/MM206Rev3-13-08.pdf
John, I agree with you, I have used this same process with very good results. If you are not worried about total waterproofness, this works best. If you are using self tapping screws with rubber o-rings, you still get a very good seal.
