Copper Underlayment

Gents, I'm considering a standing seam copper roof on a house renovation project. What are your recommendations for the best underlayment for copper? Also, one roofing contractor I've spoken to doesn't have a pan former and wants to bend sheets with a breaker bar. Will the quality of hand bent pans be up to the standard of machine formed pans?

Forming metal by hand does not have the aesthetic appeal of machine formed. In other words, it gets a lot of creases, pinched spots and dings form using hand tools. [email protected]

Wade makes a good point. As far as underlayment, one of the newer synthetic products should work. Todd Miller

Thanks. Todd, could you be more specific regarding, "newer synthetic products"? Also, my contractor put felt down to temporarily cover the plywood. I assume we should pull that off (and all of the nails) before putting the final underlayment down, correct? (I'm getting the impression that several of the roofing contractors we've spoken to may be familiare with standard aluminum roofing but not copper. With the amount of money we're talking about, I want to make darn sure they are doing the job correctly!) Thanks!

I would leave the felt in place. There are a number of synthetic underlayments available and they could be installed over the felt. Some of the names of these products include RoofTopGuard, Titanium, SharkSkin, Palisade and Tri-Flex. Todd Miller
