I like the hip roofs.  No matter which way the wind comes it’s at a negative AoA.  Well, zero, I suppose, overall, but you know what I mean.

That suggests an idea to me:   a vented hip.  Viewed from the side, in ascii art it would look something like:  / —– \ , although I expect the slashes would be at much lower angles, and there would be more overlap with the hyphens.

I’m not sure how you’d calculate what the optimum opening at the top is.  You’d want the air displaced by one side to “shade” the positive AoA of the other.

On the other hand, a flat roof would probably work, because it did, until it got structurally compromised by rot.
