It is doubtful that wind and rain shielding is the greatest function of roofs. Today, people can specially make waterproof and anti-seepage coating on the roof when covering houses. The ancient building roof is subjected to leveling and waterproof treatment, and the term of the specialty is called as 'tarpaulin back'. From the step of laying the roof boarding on the outermost layer of the wood structure to the step of building the tile surface, seven steps of the process are required, namely the wood roof boarding, the seam capturing ash, the guard plate ash, the mud backing layer, the ash backing layer, the bottom tile plaster and the tile surface.

The traditional covering process for ancient building roof includes nailing splayed wooden strip on the roof plate and plastering. The ancient building roof is plastered, and the ancient building roof is much like 'priming' during makeup. The foundation is made of foundation liquid, pressed powder and loose powder, and roof makeup is made of various materials, which are called Jiujiang eighteen ashes in the row. The ash is a paste, the pulp is a suspension liquid, and the ash and the pulp can be used together after being pretreated according to respective characteristics. The first step of cosmetic priming is to cover the blemish, and the back of the cover is coated with 'guard board ash', so that the clear gap on the cover board is filled while the cover board is protected. Then, on the guard board ash, the lime and the loess are mixed according to a certain proportion (three ashes and seven soils are adopted more), and two or three layers of mud back which is smoothed by the mud are covered on the guard board ash, so that the purpose of shaping the roof is to smooth the curve of the roof. However, the adhesion and the firmness of the mud are not sufficient, so that 2 to 4 layers of mortar with different components are coated on the mud to form a mortar back. In civil houses, straws are mostly added into the plaster, but hemp with higher cost is used in forbidden cities so as to increase the strength and the grabbing force of plaster backs and prevent plaster on roofs from slipping.

The inventor of the application finds that although the traditional tarpaulin technology can enhance the waterproof performance of the roof to a certain extent in the long-term ancient building renovation process, the wooden structure is adopted, and the guard plate ash and the ash back layer on the upper layer of the wooden sheathing board can transmit partial water to the wooden sheathing board in the long-term use process, so that the wooden sheathing board is corroded to a certain extent, and the corrosion of the wooden sheathing board is the main reason for the failure of the ancient building roof.
