Flat seam roofing material? - HO scale - Model Railroader Magazine
Nice prototype, Jim, and a good-looking model of it.

.....Anyway. I think the foil products may be the only option, but in that case I think I might simply use very thin strips of styrene butted together, seeing as how it's all going to get painted. In that case maybe 1x2 scale strips laid flat on the panel edges (rather than upright) would look like the folded seams. So maybe the Evergreen product could be modified.
The folded seams would likely be okay over the walkway (they'd be vertical), but I think that lap seams would be better on the stairway roof. I'd use metal duct tape (real metal, not the fabric stuff). Since it has a paper backing, you can pre-cut all the necessary pieces, then peel off the backing when you're ready to install it. Use a smooth, hard tool to burnish each sheet as it's applied - this greatly improves the bond.
I used the tape to represent the sidesheet patches applied to ARA and X-29 boxcars - these areas were prone to rusting.
