We carried out experimental research to clarify the effects of different construction method on snow-sliding properties of sheet-metal roofe. In this experiment, the construction methods of roofing adopted were flat plate, standing-seam roofing, corrugated roofing, flat-seam roofing, diagonal roofing and stepped roofing. Experimental results clarified that the snow-sliding velocity of sheet-metal roofing is greatly influenced by the type of construction method. The sliding velocity of the flat-seam roofing or stepped roofing tends to be greater than that of standing-seam roofing or corrugated roofing. Furthermore, in roofs utilizing the same construction method, the snow-sliding velocity is affected by joint details. It was also confirmed that the interval and form of joints, e.g., flat lock seam and steps joint, influence the snow-sliding direction.

In this study, we investigated the effect that the quality of accumulated snow on the snow's resistance to sliding. First, we observed changes in the quality of snow that had accumulated on the roof of a building. It was found that the particle size of the snow increased to approximately 2mm after one week and that the water content of the snow increased. Next, experiments were conducted to determine the effect that particle size of snow on a sloped roof has on the snow's resistance to sliding. The results showed that the resistance to sliding decreased as the particle size of snow increased (i.e., as the snow became more granular). The effect of particle size on the snow's resistance also depended on the degree of snow melting. From the facts described above, it is possible to utilize the effect of particle size on the snow's resistance for control of snow sliding on a sloped roof.
