The owner wants a retrofit steel roof built over this copper roof. The original roof was a ballasted epdm and it leaked and couldn't be fixed and so 5 years ago they had this flatseamed copper roof installed and they have had to deal with even more leaks ever since. The guy that put this copper roof on had done a lot of flat seam roofs and never had this kind of problem. The seams a cracking all over.

I nailed it. :woohoo: :woohoo: :woohoo: But I bet at closer look the solder joints are not good enough like tinner said combined with no expansion jount = What a shame :ohmy:

I wasn't allowed access to the roof, but I could see everything I needed to see from the tower, and underneath, just to bid a new retrofit roof. If I get the job I will investigate the problem with it futher.

I noticed there was not any expansion joint also..I looked up the Copper Development specs on flatseam and it says any roof direction over 30' is suppose to have an expansion joint. This roof is about 62 x 40 so I know he screwed up there.

It's to large of an area with out an expansion joint. It self-destructed. He may have use the wrong solder also.(To hard)

We need pix. What ddi he do? 'Edge' solder the seams without sweating them? THe edges are done wrong. Walls call for 8'-10' by 4" panels. Not running the flat pans up them. And those boxes need to fitted loose so the pans could move. Like you said, "What a shame".

Doesn't look that bad from here!
