Ken, thanks for your offer. I currently have an existing 28'x36'x 11' (bottom of the trusses) high. I want to to raise the roof and store the wife's craft supplies and misc truck/car parts i.e. fenders, hood, etc. My plan is to place an I-beam in the center of the 28' making two sections of 14' but going 20' long. This beam will be placed inside the existing walls about 9' high, supported with 4' x 4' x .250" thick square tubing on each end. Planned to use 2" x 6" x 14' floor joist x 24" apart and 3/4" x 4' x 8 T/G sheathing for the floor. I'll remove the existing trusses and replace it with a "Dutch" type roof, 6-7 feet high. I went to Home Depot and they suggested a laminated type beam about 12"h x 8"w x 20' long, but I'd feel better using steel rather than wood. No building inspector involved. With that, I thought that 8" h x4" w x '250" thich I-beem shoud work. Your advice greatly appreciated.
