Thinking about using a PBR metal roof on 1:20 pitch. This is to flat by manufacturer standards for PBR but less expensive than standing seam and easier to install. What I was considering was using wood block spacers under the ribs where fasteners are placed with "NO FASTENERS" in the valleys. Any one have any thoughts on this? Wood blocks would be installed via 3M tape at pre drilled hole locations in the PBR panel.
