   This sounds like a terrible waste of copper to me.

   This sounds like a terrible waste of copper to me too.  Why not use a TPO or EDPM roof system?

   will the tpo or epdm last as long?

   Im sure you have a reason for covering up the copper roof so I wont scold you on the topic...I have always used a mixture of rigid insulation, ice/water shield (self healing) as a base, then epdm. I like the flexibility you have with sealing sleepers,curbs etc... 

   Epdm will adhere to the sleepers no problem, how will you attach the sleepers to the copper roof without damaging it?

   Guess Im not following you on your question, is your concern damaging the copper or how to adhere epdm to your sleeper?

   To adhere epdm simply glue it as you would to any other thing, kind of like with contact cement, glue on the epdm, glue on what you want the epdm to stick to, let it dry a bit and presto! (simplified)

   good luck...

   thanks for the input. i'm not using the copper for looks im using it for longevity and its waterproofing properties.I also think it would be hard to walk on standing seem roof or put furniture on it. I was worried about the epdm reacting with the copper. The sleepers will be attached to the perimeter of house not down to the copper.

   here's your tool

   @bradh-

   YOur follow up comments make no sense whatsoever. Epdm reacting to copper? Walking and putting furniture on standing seam roof? Sleepers not down on the copper? How do you expect the sleepers to be supporting the decking? And what happened to your IPE decking? Isn't that what you'd expect to walk and put your furniture on? Your project planning sounds like a real circle jerk.

   BTW, if anybody's being a tool here, then it's you.

   let the copper work for you in other ways...

   You may want to consider taking the copper roof up and recycling it. Use those funds towards purchasing the new materials you really should use for the job. See sketch. If you're concerns about staying dried in while doing the work, then install Grace Ice and Water over your structural roof sheathing right after the copper tear off. The Grace will give you additional piece of mind during and after the work... and is not all that expensive in the whole scheme of things.

   examples...

   These photos show some of our PVC decks over EPDM. The sleepers were held in place (as Mark122 suggested) but rather with EPDM on both the deck and sleeper bonded to itself. This will hold up better than copper to EPDM glue bond. Also, you can see EPDM lapped over sleepers as counter flashing near the house areas that need to support decking, but also drain.

   A roof with an 1/8 in 12 is essentially a flat roof. It will have standing water. Standing seam metal roofs require at least 1 1/2 in 12 pitch. A standing seam flat roof will leak. Standing water will be taken up through the standing seams by capillary action. No one could ever guarantee this roof. What ever you use under the deck will have to be seamless. All the roof decks I have built in the last 20 years have used cementous waterproofing and tile.
