Which would be better?
I have corrogated roofing over 6" beams. I love the aged look and if possible would like to re-use the roofing. I would like more insulation - (walls are great, plastered adobe firred out on inside - at least 12" thick). Any ideas which woud be more economical? Adding something (rolled insulation? foam? ??) over the existing roof as-is and buy new corragated panels - how would I attach them? (and... I love the look the aged ones have) Remove corragation and fastening new 6" beams on top of the old, then add more insulation? A guess would be there's 1500 sq ft of roof when also accounting for the overhangs and pitch. Any guess on material costs?

Sorry if my questions are naieve - getting divorced and need to do, and learn to do, things on my own.

Roof Insulation

The easiest would be to add insulation and vapor barrier between the rafters on the underside and enclose with beadboard, tongue-&-groove boards, or drywall. But then your beams will be hidden.

If metal is removed, then you can add 4-inch thick foam blocks between the sheathing and metal and secure the metal with long screws made for this purpose. Just a couple of ideas. I am sure the pros will have other suggestions. Good luck with your project.
