STRUCTURE BUILDING - The Foamcore/Veneer method
An OnLine Clinic presented by HORAILROAD.COM
After all walls have been rounded to the roof surface, the whole roof is painted.

Early in this clinic I noted that foam core takes paint well but will warp.  On a small structure like this the painted roof is so small it is held in shape by being glued to the wall sections. If this were a very large structure, then support on the underside of the roof would be needed to prevent warping from paint. 

I suggest ribbing like strips of foam core on edge
hot glued to the underside of the roof.
