对建筑工程而言,屋面作为重要的组成部分,对建筑功能的发挥具有重要的作用,施工技术的作用在很大程度上决定了施工的质量,甚至会决定建筑的使用以及寿命。尤其实在雨季或者较为潮湿的地方,因为气候的原因对屋面的施工质量有着更高更严格的要求,这就对施工技术的发挥提出了挑战。防水施工技术的应用可以有效保护建筑的结构质量,本文从建筑工程屋面防水技术的现存的问题出发,进行科学合理的分析,进而探寻提高施工质量的技术措施 For construction projects, roofing is an important component that plays an important role in building functions. The role of construction technology largely determines the quality of construction and may even determine the use and life of the building. Especially in the rainy season or more humid places, because of the climate of the roof construction quality has a higher and more stringent requirements, which put forward the construction technology to play a challenge. The application of waterproof construction technology can effectively protect the quality of the structure of the building. Based on the existing problems of the waterproofing technology of the roofing of construction engineering, this paper conducts a scientific and reasonable analysis, and then explores the technical measures to improve the construction quality
