Webb8 nov. 2024 · Snow load shape coefficient $\mu_{1}$ The purlin roof we are looking at in this example counts as a pitched roof. When increasing the angle of the roof slope over 30°, the snow load shape coefficient $\mu_{1}$ can be decreased below 0.8 due to sliding of the snow off the roof. WebbUsing a simple roof pitch calculator can help you determine the degree of your angle. The minimum pitch for a lapped, non-sealed metal roof is 3:12. That ratio equals just over 14 degrees. Lapped metal roofs with sealant between the laps can go as low as ½:12, which equals around 2.5 degrees.
