Are you thinking of doing a commercial building? Why not consider a metal roof system? Look at the options and cost savings over a conventional roof with bar joists and a built up roof. Metal Building Systems can be very cost effective. Metal systems can also be complete with wall panel systems. This detailed quote below is a framing system and panel for the roof only, at less than $ 6.00 psf, and $ 4.00 psf labor. Call for more details, let's discuss your project.
