The copper would probably expand and contract too much - buckle in the summer, and maybe split over time. That's why it's recommended to install the copper in smaller pieces.

You can get 32 oz copper 4x10, it would be costly.

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. :)

It would not be wise to install in one piece if you could even find it .

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!
