Snow Load Formula (ASCE 7)


                        Pf = 0.7 x Ce x Ct x Is x Pg

                        Ps = Cs x Pf (sloped surface)

                        Ce = Exposure factor, Ct = Thermal factor

                        Cs = Slope factor based on tilt angle

Snow Shedding by Tilt Angle

Tilt Angle	Slope Factor	Shedding
0-10	1.0	None
10-20	0.9	Minimal
20-35	0.7-0.8	Moderate
35-50	0.5-0.7	Good
50+	0.3-0.5	Excellent
