okiyane　置屋根
KEY WORD :　architecture / folk dwellings
　
The upper roof erected over storehouses, kura 倉, of the *dozou 土蔵 type. In rural districts where tile was unobtainable, the okiyane provided a weatherproof canopy for the fireproof storehouse. The shallowly pitched lower roof of the storehouse, covered with mud daub *tsuchikabe 土壁, and plaster finish *shikkui 漆喰, formed the the base upon which the independent structure of the okiyane was erected. The frame was usually a combination of vertical roof struts koyatsuka 小屋束, purlins *keta 桁, and rafters *taruki 垂木. The roofing material was either thatch, *kayabuki 茅葺, or shingles, *itabuki 板葺. In this way the vulnerable plaster was protected from rain.
