This detached garage in the ‘Ville is getting a facelift, starting with a new 40 year Pro Rib steel roof. Start with 2×4 nailers (24″ on center) to create an even and structural subsurface. Finally come the Pro Rib panels with all the necessary trim. The peak line sag was already braced, so we brought the ridge cap up about 6″ to lessen the effect.
