flat seam roof panel size

I am going to be installing a flat seam copper roof on an 1890s house. I've seen the panel size given as 18" x 24" but I"m wondering if I could go to 36" x 18" to better fit the copper sheets I'll be working with. Is this too large to allow for proper expansion/contraction? I will cleat each side and be doing a 3/4" fully soldered seam. Also, my contractor would like to lay down ice-guard immediately in case of rain. Could I put rosin paper down over that to provide for a slip sheet? Thanks in advance.

I am no expert in hand-crafted things but I would think you'd be okay with the larger size panels. Also, it would be fine to pur red rosin paper down over the self-adhering membrane.
