I have a a roofe that needs replacing. I will do this my self and have done regular fiberlgass before. Due to my age (54) I would rather install metal roofing so as to not need any more while alive. How much more would metal roofing (good quzlity) cost applyed to bare roof than fiber glass shingles?
Congrats on deciding to do it yourself. I have done lock seam roofing, and if you have a simple roof line, it is literally a snap! Start looking for a roofing supplier. If you are in Oregon I would send you to Bruce and Dana in Salem. They were some of the early lock seam rollers, and actually hold a patent for their style of joint.
AFAIK, there is no national supplier, you just have to deal with local rolling mills. Some of them will only sell to contractors, some will give contractors a substantial discount, others will sell to anybody with cash in their hand. Shop around. Anybody who sells lock seam roofing will have drawings and directions for roof penetrations, flashing, ridge vents, etc.
If you are putting steel lock seam over plywood, the thin stuff (29 gauge) will work fine. The coatings are what give it its longevity. If you live in hail country, you will eventually get an interesting hammered finish on the roof. If you go with copper, the cost will be higher and you will have to use a heavier gauge, but there is a certain cachet about having an eternal roof.
There is a good discussion of this in the current (August) Consumer Reports. For a DIY project there will be many caveats so do your research to be sure of the results. Quality of the sheet with respect to gauge, coating materials will be a prime factor. Treatment of cut edges, cutting tools are all considerations. Besides standing seam there are architectural stampings in steel and aluminum. The field right now is fascinating, so have fun looking it over and post your results for the project. Good luck.
