AbstractA more rational approach to snow loads for the design of roofs in the National Building Code of Canada has been made possible as a result of a ten-year country-wide survey of actual snow loads on roofs. The two-fold objective of the survey was to determine how much the average roof loads can be reduced below the level of ground loads and to assess factors which result in the accumulation of higher loads on particular areas of various shaped roofs due to wind, sliding, etc. This paper describes the survey, its results, factors which affect snow loads and the present requirements for snow loads for the design of roofs in Canada.
