Pitch for roof on portable bldg

Looking to manufacture portable buildings. They will be narrow so the pitch can be covered with one sheet of metal -- no seams across the slope. What would be the lowest pitch I could use for runs of 8 feet, 12 feet and 14 feet? What type of metal roofing is required to do a low (<2:12) pitch?

Steve, Thanks for the question. The building code (IBC section 1507.4.2) limits roof slope based on the type of panel, specifically the sidelap, not length of panels. For lapped, non-soldered seams without lap sealant, the minimum slope is 3:12. For lapped, non-soldered seams with lap sealant, the minimum slope is 0.5:12. For standing seam systems, the minimum slope is 0.25:12. When less than 2:12, there certainly should be sealant in the sidelap, if not a standing seam system.
