The purpose of this survey is to clarify the roof snow accumulation of mid-to-high-rise buildings in heavy snowfall cold region. We investigated roof snow depth distribution of residential buildings with flat roofs in Asahikawa, Hokkaido, Japan. The following results were obtained. (1) The measurement showed that roof snow accumulation and plot of building placed to the wind direction were relatively high. (2) Insulation properties of roof have a great effect on the roof snow depth distribution in the early snow days. (3) In case of the short axis of building placed parallel to the wind direction during snowfall, the ratio of snow depths on the ground to that on roofs was 0.32〜0.38 at the time of maximum snow depth. In case of the long axis, the ratio of snow depths was 0.42〜0.58.
