2, the top of the temple: the roof has four slopes and five ridges. The front and rear slopes intersect to form a transverse positive ridge, and the left and right slopes intersect with the front and rear slopes to form four vertical ridges extending obliquely from both ends of the positive ridge to four corners of the house. The eaves are slightly upturned, and the slopes on all sides are slightly concave. Also known as four tops. Before the Tang dynasty, the main ridge was short and deep on all sides, and it was lengthened after the Ming dynasty.
3. Suspended peak: the roof has two slopes and five ridges, one positive ridge and four vertical ridges. Both ends of the main ridge extend out of the gable, and the outer edge is built along the vertical ridge flush with the ridge head to protect the sandalwood head from wind and rain. (The roof has a double slope, with both sides protruding beyond the gables. There is a positive ridge and four vertical ridges on the roof, also known as picking the top of the mountain. )
4. Xieding Peak: The roof is a combination of a suspended peak and a temple top, with the upper two-thirds of the suspended peak and the lower one-third of the temple top, thus forming the shape of four slopes and nine ridges. The nine ridges are one positive ridge, four vertical ridges on the upper part, and four ridges between the four corners and the vertical ridges. (that is, the upper part of the roof with four slopes turns into a vertical triangular wall. There is a positive ridge, four vertical ridges and four ridges, so it is also called the top of nine ridges. )
5. Roll shed roof: The overall appearance is the same as that of hard mountain and hanging mountain, the only difference is that there is no obvious positive ridge, and the slope in front of the house rolls back in an arc at the ridge. If the above four kinds of roofs are angular and show a kind of masculinity, then the roof of the shed has a unique feminine beauty of curve.
6. pyramidal roof: It is the roof shape of circular and regular polygon buildings. Except for the circular pyramidal roof without ridges, the ridges converge from the roof and the central roofs of all corners, and the slope between ridges is slightly curved. The eaves and corners of all kinds of roofs in the south of the Yangtze River are higher than those in the north, but pyramidal roof is the most disparity, so it is called cornice. This shape is not only easy for rain to drain, but also has the aesthetic feeling of lightness and flying.
