I have a job that I got the go ahead on. The flat roof area will be epdm membrane. They want the look of copper without having to do the whole roof in it. What I was thinking to elimnate the look of the termination bar. I could bend a J and turn it upside down and hook it undder the top of the termination bar. Then the long leg of the J would cover the bar. It would only have to be about 2" long.

Here is a pic of what is there. The flat area will be epdm then the vertical and the built in gutter will be copper. What do you guys think a good idea?

Yeah - I don't think I'd do what you describe. Term bar is a barely acceptable flashing method, IMHO. Why not counter flash the membrane with copper? Hem the bottom edge of the copper to reduce the potential of the rubber contacting a sharp edge. We use that detail from time to time. Usually we strip in a copper "L" against the wall and counter flash it instead of turning the rubber up the wall.

No I don't mean on the brick wall I mean on the flat vertical section above the built in gutter.

Oh - The gutter liner pan should extend back up and lay over the rubber on the roof surface. Then cover tape it. No need for term bar.

How soon are you doing this job? We're laying the rubber on a similar project tomorrow, but it will be next week before the gutter liner goes in. I'll try to get some pics for you.

I have never done it that way. The tape seal is good enough?

Only way I've ever done it. Never had a problem.

We usually (but not always) put seam tape under the copper roof flange just in case.

I'd question the wisdom of piercing the liner with the termination bar screws. There should not be any fasteners piercing the gutter liner anywhere. It needs to be able to slip when it wants to expand and contract. There'd be a metal "mixing" problem unless stainless screws were used. Use galv screws thru the copper and they'll probably disappear before the cover tape comes loose.

I'm no roofer but i beleive ther is apotential problem with your diagram.

If there is not enough slope on the flat roof water will sit on the built up portion until it evaporates!?

It has always been a pet peeve of mine to see this on flat roofs.
Just my two cents.

Cole,
It has been a few years like 16 since I have done any comm. roofing with EPDM, But seeyous diagram is the way we always did it,
as far as Ashcons comment about the built up area its not like its going to be a large build up, the thickness of copper and that of the seam tape.
