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.
