Seismic countermeasures on roof snow control method for timber houses in snowy areas were analyzed. Data for the analysis of roof snow control was obtained from the Japan Housing Finance Agency and from previous studies. Roof snow control methods used in prefectures from Hokkaido to Fukui were categorized into “keeping snow on flat roof”, “snow sliding” and “snow removal”. Seismic countermeasures on each roof snow control method were analyzed for each prefecture.The results indicated that the “keeping snow on flat roof” and “snow sliding” methods were used for roof snow control in Hokkaido and Aomori Prefectures, while the “snow sliding” and “snow removal” methods were adopted in Niigata Prefecture. Regarding seismic countermeasures in the snowy season, considerations on “dynamic behavior of roof snow due to shaking”, “adfreeze between snow and roofing materials” and “increase in seismic load due to increase in snow load” are required for each roof snow control method. The necessity of further examinations on seismic countermeasures for each roof snow control method was clarified.
