Sliding Snow Loads
Publication: Snow Loads: Guide to the Snow Load Provisions of ASCE 7-22
Abstract
From a structural standpoint, snow sliding off a roof is beneficial as long as the sliding snow does not collect in an undesirable location. The roof geometry and the site plan for the immediate adjacent areas should be such that the snow sliding off a roof does not pose a hazard to people, parked cars, or other adjacent objects. ASCE 7-22 does have design load provisions for snow that slides onto an adjacent roof, which are discussed in this chapter. Sliding loads can also occur on lower-level roofs that are separated from but close to a higher-level roof. Per ASCE 7-22 procedures, sliding loads are required for a separated roof that is close enough (within 15 ft horizontally) and low enough (ratio of vertical separation to horizontal separation greater than 1.0).
