I was browsing this site's standing seam roof installation pictorial and a few things came to mind that might confuse someone considering a metal roof. I've worked with both terne coated steel and copper, so I have a little experience here.
- The unit shown in the pix used to form the pans is a roll former, not a brake, although pans can be formed on a brake and a brake is indespensible if you're going to do some metal roofing. Rollformers are trailer-mounted units and make short work of pan fabrication. I rented one over the weekend for $200 about 5 years ago and formed every pan for my 12-square house roof; definitely worth every penny.
- The pictorial shows the pans being laid directly on the roofing felt. I've been told by more than one roofer and the Revere copper folks that this is bad practice: In the summer, the tar in the felt softens and sticks to the underside of the pans, then as the roof cools down, contracts and moves, the felt tears, so any potential future leak can get it there. The preferred solution is to put a layer of rosin paper over the felt before the pans are installed to prevent this situation and allow the pans to expande and contract freely without affecting the felt below.
Hope this helps.
