Rebuilding a GN 25 foot wood caboose. Does not have a flat roof. Will a TPO type material work on a slightly curved roof.?

Ok, what's "TPO"? I do know that rubber membrane material ("EPDM") in .060" thickness, is excellent for curved or straight wood deck caboose roofs.

And, it has the appearance of the original canvas.

EPDM/rolled rubber is awesome stuff, and it just needs a smooth surface as a base to be glued onto. We use plywood, as we end up having to do a lot of subroof repair on most of our roofing jobs.

The rubber will last for decades, and can be used on any shape of roof.

DO NOT use canvas and tar. It won't last. If you don't re-tar it regularly it will let water in. We have an otherwise structurally sound car that has been condemned due to mold because of this.

The tar is probably the problem. Elastomeric and canvas has worked well for me, and nothing will last if it isn't applied to a good substrate and maintained.

Thermoplastic Polyolefin. Single ply with an embedded scrim. Never used it. It seems to be all the rage for commercial re-roofing. I wonder how flexible it is?
