The invention relates to a non-shrinkage cement-based roofing material, belonging to the technical field of building materials. The roofing material is formed by mixing cement, activated and inert mineral admixtures, plaster, expanding agents, glass fibers and organic synthesis fibers, chemical admixtures, sand and the like based on a certain proportion. At the construction field, right amount of water is added and stirred evenly, and is constructed by hand spreading or spraying. Regarding constructed roofing, the thickness of the waterproof layer is 35-50mm and the area of the separate bin is 50-300m. The non-shrinkage roofing material has high strength, good volume stability and excellent waterproof property, can be used for thin layer construction and is convenient, fast and flexible in construction. The roofing material is low in cost, convenient in production and changeable in production scale, and is applicable to the requirements of construction of villages and small towns. In addition, the roofing material utilizes a substantial proportion of industrial residues, thus not only reducing cost but also conducing to environment protection.
