Carport Minimum Roof Pitch. The roof usually slopes away from the house, so the house must be tall enough for the low side of the carport roof to be at least 8 feet high. Also, it is currently a bug roof.
You need to consider the slope requirements of each panel to determine this minimum slope. The slope of your roof is vital as a moisture barrier, among other things, and having a roof that is too flat can potentially cause your shed to cave in. However, minimum slope for a flat roof by building code here is 2%.
A roof of pitch 7/12 (30°) is manageable, but caution should be taken.
I will tear it off down to the 1x8 pine decking. Does using a sa self adhesive rolled roofing allow any other style metal roofs to qualify to be put on with this very low slope? Minimum slope and optimum for the carport. The roof should have a minimum slope of 1 in 12, but a slope of 3 in 12 or steeper is better in snow areas.
