| http://www.w3.org/ns/prov#value | - I am dealing with a roof design and an architect, he wants to design a standing seam metal roof for a 1:12 roof, and we are trying to see if there is a building code or standard that tell us the minimum slope for a standing seam metal roof, is it has to do with the rib height, the gutter size, counter flashing designs?Thanks in advance.
