That's why it's recommended to install the copper in smaller pieces.   Slate_man (Slate_man) Senior Member Username: Slate_man Post Number: 650 Registered: 01-2007 Posted on Wednesday, April 20, 2011 - 09:36 am:        You can get 32 oz copper 4x10, it would be costly.   Spp (Spp) Junior Member Username: Spp Post Number: 18 Registered: 09-2008 Posted on Monday, April 18, 2011 - 09:17 pm:        Thanks Walter. It seemed odd to me at the time that they could even source a single sheet of copper the size needed but I didn't pursue it with him further -- I just nodded my head and went along with what he was telling me. I figured I'd ask the group though.   Walter_musson (Walter_musson) Senior Member Username: Walter_musson Post Number: 189 Registered: 07-2006 Posted on Monday, April 18, 2011 - 03:34 pm:        It would not be wise to install in one piece if you could even find it .   Spp (Spp) Junior Member Username: Spp Post Number: 17 Registered: 09-2008 Posted on Monday, April 18, 2011 - 11:03 am:        We have a flat copper section of roof that is 78 years old. It's maybe 9'x4' in size (estimated) and it has been recommended that it should be replaced. I've been given estimates on rubber roof replacement and also copper. One of the estimates that I have received for copper replacement outlined using a single sheet of copper vs. the "normal" flat lock solder of smaller panels. I've read a bit online and in the slate book about the flat lock panels needing to be under a certain size to allow for expansion/contraction but I didn't find any comments pro or con about using a single sheet of copper for an area of this size. Any thoughts? Thanks!
