A flitch beam sounds interesting. The problem with 2-by timbers, like 10x2 or 12x2, is their thickness. A 12x2 would drop down 12 inches, and the highest point of my carport is only 8-feet high. In its 16-foot run, it has to drop at least 4 inches in order to run off. I can't be using material as thick as 12x2. That's why I was considering doubling or tripling some engineered wood. But at that point it seem like steel would be the some cost and better performing. I dunno. Like you said, I may have to talk to an engineer.
yeah, glulam is probably a non-starter too if there's no height available.
I think you can do triple flitch.
So like : [w]|[w]|[w]
maybe that'd work with 3 2x6s , 2 steels, all boted together.
