OK 4th time was a charm on the roof. This morning I cut it back open and tried one last thing... and it worked mucho better!

I started by setting the peak of the center arc of the roof with a brace all the way up from something solid (the floor) instead of the flexy truss I had hanging from the doorway frames before. This got me (again) the arc I wanted. Then I tacked in a backer plate to give the entire center of the roof some beef.
