I would install two expansion joints evenly spaced on the 86 foot section. And at the hips.

Bring the panels together with about half an inch min. between them. Solder a water stop similar to a low slope standing seam cleat vertically about an inch away from the inside hem on both. Cap that and hammer snug.

I cannot remember where i saw this but some company out there makes 10' long sections of copper/epdm expansion joint.
It is about 10" wide and was composed of 2-4" wide x 10'long copper pieces joined togather in the middle by a .080 reinforced epdm.
Maybe someone alse hereknows more about this.

This site http://www.copper.org/applications/architecture/arch_dhb/roofing/flat_seam_roofi ng.html
has an example of a expansion joint I could use on the hips, but the long runs are still a problem while keeping the roof flat

the roof will be artificial slate (yuck) which could allow for raised expansion joints but I still have the 86 foot side to contend with, as well as 2 35 foot sides.

Can you incorporate your expansion joints into the hips?

it is a 4 sided roof. Hip joints. There a a couple of breaks, one chimney and one porch. The longest straight run is 86 feet but rounding both corners adds another 60 feet to the total.

It's not 240 continuous, straight lineal feet is it? How many and what kind of corners, etc. are there?

I tried that, the home owner has another house with both standing seam and flat seam and he can't stand the standing seam. No pun intended

I am contracting a flat seam copper snow belt around a house. 2foot stock, 3 foot up the roof with 30 inches exposed and 240 feet long. Looking for recomendations on types of expansion joints and distances between. Thanks
