The fiber cement board has the advantages of difficult deformation, difficult warping and light weight, and is very suitable for being applied to a heat-insulating and sun-proof layer of a roof. In order to reduce the load bearing of the roof, the supporting legs are formed by compounding foam plastics and a waterproof and fireproof coating.

When the roof waterproof asphalt felt is used in summer, the fiber cement board is supported above the roof waterproof asphalt felt by the supporting legs, and the fiber cement board on the upper part can reflect sunlight to prevent the roof from being exposed to high temperature. Form ventilation channel between a plurality of landing legs of fiber cement board below, be favorable to in time taking away the heat on roof, in time cool down the roof. When the wind-proof and heat-insulating roof is used in winter, wind-proof plates 3 are arranged on the periphery of the side face of the fiber cement plate, gaps among all the plates are sealed by sealing belts 4, and the fiber cement plate and the side face baffle plate jointly act to isolate external cold air from the roof. And a cavity is formed among the fiber cement board, the baffle and the roof. The cavity can prevent heat transferred to the roof from overflowing indoors, so that heat preservation of the room is facilitated.

Example two:

the heating in winter (such as southern areas of China) is not considered, the following measures can be taken:

1. removing the wind shield;

2. removing the heat absorbing layer (black paint) of the fiber cement board and the wind shield;

3. removing the sealing tape and only remaining the reflective layer (white or silver coating) of the fiber cement board;

4. the leg height is slightly higher than that of the first embodiment.
