The Different Types of TeaHouse Roof - Traditional Japanese Technology Still Being Used. Teahouse Roof Types:
1. Copper plate thatched | 銅板葺
2.茅葺き | Kayabuki | Thatching
Thatching is the craft of building a roof with dry vegetation such as straw, water reed, sedge (Cladium mariscus), rushes, heather, or palm branches, layering the vegetation so as to shed water away from the inner roof. Since the bulk of the vegetation stays dry and is densely packed—trapping air—thatching also functions as insulation. It is a very old roofing method and has been used in both tropical and temperate climates. Thatch is still employed by builders in developing countries, usually with low-cost local vegetation. By contrast, in some developed countries it is the choice of some affluent people who desire a rustic look for their home, would like a more ecologically friendly roof, or who have purchased an originally thatched abode.
3. Thatched tile | 瓦葺 | Kawarabuki
general term for a tile roof, especially one which is composed of relatively flat, broad, concave tiles *hiragawara 平瓦 and semi-cylindrical convex tiles *marugawara 丸瓦. The former are laid first and the latter act as protective covers for the seams or joints where the hiragawara meet. Setting the tiles begins at the eave edge. The eave end tiles *nokihiragawara 軒平瓦 and *nokimarugawara 軒丸瓦 have decorative pendants attached which deflect the rain as it runs off the roof. These are the basic tiles. Many additional tiles with various shapes are needed, for example, over the ridge and ridge ends, along gable edges, at corners etc.
4. 柿葺 | Kokerabuki |こけら葺 | Wood shingle
A section view of a type of wood shingle.
Wood shingles are thin, tapered pieces of wood primarily used to cover roofs and walls of buildings to protect them from the weather. Historically shingles were split from straight grained, knot free bolts of wood. Today shingles are mostly made by being cut which distinguishes them from shakes which are made by being split out of a bolt.
Wooden shingle roofs were prevalent in the North American colonies (for example in the Cape-Cod-style house), while in central and southern Europe at the same time, thatch, slate and tile were the prevalent roofing materials. In rural Scandinavia, wood shingle roofs were a common roofing material until the 1950s. Wood shingles are susceptible to fire and cost more than other types of shingle so they are not as common today as in the past.
Distinctive shingle patterns exist in various regions created by the size, shape, and application method. Special treatments such as swept valleys, combed ridges, decorative butt ends, and decorative patterns impart a special character to each building. Wood shingles can also be shaped by steam bending to create a thatch-like appearance, with unique roof details and contours.
5. 桧皮葺 | Hiwadabuki
A roof covered with layers of Japanese cypress hinoki 桧 (檜) bark shingles. The shingles are usually 45-60cm in length, 4-15cm in width, and 9-12cm thick. The extension from the overlap of one shingle over another is 1-2cm. Cypress shingles are secured with bamboo nails.
