|KEY WORD :@architecture / roofing tiles|
| The roof tiles positioned like hands joined in
prayer covering the triangular framework of a Japanese roof structure. Broad,
concave, eave-end tiles, nokihira karakusagawara ¬½¢, placed
along the pitch of the gable on a gable roof *kirizuma
yane ØÈ®ª, or hip-and-gable roof *irimoya
yane üê®®ª, of which the uppermost tiles meet at the peak. The pitch of
the tile must conform to the pitch of the gable. Semi-cylindrical tiles *marugawara
Û¢, also called *ogamidomoe
qb, are set over the seam where the two broad concave tiles meet at the top. The
earliest extant example is found on the aisle *hisashi
ù, of Houryuuji *Daikoudou @²åu° (990) in Nara. The incline of
the roofs was gentle. Ordinary broad, concave, eave-end tiles *karakusagawara
¬½¢, could be aligned along the sloping edge above the bargeboard quite easily
because the incline of the bargeboard was much the same as that of the roof itself.
With the construction of a hidden roof *noyane ì®ª, over the entire building in the late 10c, the roof and the bargeboards not only curved differently, but on many buildings, the bargeboard was lower than the roof, requiring a transitional area called a drooping verge *minokou ¥b. The bargeboard also became steeper than in earlier centuries creating the need to increase the height and incline of the broad, concave tiles on either side of the gable peak. These tiles are really the same as hanging, broad, concave eave-end tiles *kake karakusagawara |¢, except for their position and shape which conforms to the angle of the peak. The hanging semi-cylindrical cover tile, kakemarugawara |Û¢, also had to be heightened to cover the joint made by the ogami karakusagawara.
