Richard: I see the "purlins" in the photo. They are not the right size and the braces are not cut under them or attached to them in any way as far as I can see.

No, probably nobody will do anything about it now. I probably see more incorrect roof framing in houses built in the last 10 to 15 years than any other defect. Most framers are not given proper training or none at all. Just show up on the job and jump in there and go to work.
