Although in recent years the construction of a roof garden to get a certain amount of development, however, found that a large number of green roofs after the completion of the course, there are many problems, which are embodied in government and administrative departments concerned enough, technology promotion detrimental, costly and old ideas. (1) regional development imbalance due to an imbalance of more than 600 cities, urban infrastructure and geographical differences in economic development, there is a big difference. Green roofs stage mainly in big cities and economically developed regions to carry out, even in the same city, the new city and the old town can be green roof conditions there is a big gap. Many cities in greening or blank. (2) The Government is not enough attention to the main directions of the government is currently working on urban greening limited ground greening, some cities in the absence of available land is transferred to the old green parkland transformation, the role of the green roof can not be understanding of the difficulty of green roofs consider too much, and therefore less investment in research, experiment, technology promotion, lack of special management of construction enterprises. In the current social management, Xi'an roof garden, the government's guidance and promote tend to have less effective, the development status of Chengdu green roof fully illustrates this reality. Leaking roof garden roof garden construction is one of the biggest problems affecting quality of the project and the results, as the main reason causing leaking roof garden. (1) waterproof layer structural defect exists in the construction of the current building waterproof materials can be divided into five categories, namely bitumen membrane, waterproof polymer sheet, building waterproof coatings, building sealants and seepage, and other special purposes waterproof material. May be due to the construction unit quality awareness, Xi'an roof garden casing, resulting in a waterproof layer structural defects occur during construction. Material selection, design disadvantages, construction quality problems have some impact on the performance of the waterproof layer. Waterproof layer construction should pay attention to weather conditions, it is directly related to the construction quality problems, especially the roof garden should strictly. And waterproof layer often associated with cross layer operation, construction quality level of these correlations have a significant impact on the quality of the waterproof layer, Xi'an roof garden design, so pay special attention to the construction. Currently construction units in different ways, counterfeit products flooding the market, so the materials testing, construction supervision must be strict.
