You do not wnat to use treated lumber.
Other than that, all information must be based upon load tables and other details provided by the manufacturer of the roofing you install.

I would have assumed that treated purlins would be the way to go, but I guess not. By the way, I'm installing a steel roof over existing shingles. The existing roof is not leaking, but it is very, very old and I figured I had better replace it before it leaks. I am considering either using purlins or screwing it directly to the existing roof. Do you have any advice? The manufacturer says I can do it either way, but I'd appreciate your expert opinion.
