Title: Roof loads due to local drifting of snow

Ref Code: DG439
Authors: D Currie

Abstract1: Following a review of some areas of difficulty, BS 6399-3 was amended in 1997. The main changes related to determining load shape coefficients for local drifting of snow, and using the snow load statistical factor to produce estimates of loads with probabilities of exceedance different from 0.02. This Digest presents background information and design requirements for local snow drift loads on roofs in line with the amended British Standard. It is aimed at architects, structural engineers, contractors, and manufacturers and suppliers of roofing systems.
