I'm thinking that a spar/skin roof with an inner & outer layer is simple, light, easily insulated, strong & works well structurally. The curved panels provide strength laterally, 1/8" plywood is strong & light. Granted, the foam insulation simply acts as a "web" in that it ends up being a simple, weak compression member, with no real ability to transfer loads, but in this application it really isn't necessary. In the flat sections, spars supply resistance to bending loads & axial forces are transmitted into the side panels, where they are distributed into the frame, eventually.
I guess my question would be, with the accumulated knowledge from builds spanning many years & empirical evidence to "support" it, why reinvent the wheel in this instance? Sure, there's plenty of room for innovation in a build, but putting legs on a snake has never been my idea of fun. I guess I spent too many years dealing with people who had vast amounts of education & theoretical knowledge, while all it ended up doing in most cases was to cost more in the end product & make a less efficient use of time for me at the computer.
