Sloped Roof Snow Loads
Publication: Snow Loads: Guide to the Snow Load Provisions of ASCE 7-22
Abstract
Section 7.4 of ASCE 7-22 provides information needed to convert flat roof snow loads into sloped roof snow loads using the roof slope factor. As skiers know, it is difficult to “keep” snow on steep trails. For roofs, the reduction is caused by snow sliding off after initially being deposited or snow not adhering to the roof surface in the first place. At lower roof slopes where the sliding mechanism is slip at the snow/roof surface interface, R. Sack presents values for North and South facing slopes, while Chiba values are for East-facing slopes. Section 7.4.5 provides sloped roof snow loads for air supported structures with slippery exterior fabric surfaces. Given the various factors in ASCE 7-22 on which the roof snow load is based, one may ask how well observations compare with prescribed loads. The ASCE provisions provide an acceptably small probability of serious overload, whereas the others do not.
