With the acceleration of urbanization, the contradiction between building land and living environment is becoming increasingly prominent. Building sustainable urban architecture has become a topic of great concern, and roof greening has gradually become the inevitable trend of modern architectural development. With the support of sponge city theory, this paper studies the design of green roof in residential area. Firstly, taking roof greening as the research object, this paper makes a preliminary study on its environmental improvement effect by means of experimental research and theoretical analysis and designs the conventional design of roof greening based on the research conclusion. Through the cooling effect experiment, the cooling effect of roof garden in summer is preliminarily studied. It is found that the daily change of temperature of green roof is closely related to solar radiation. With the increase of solar radiation, the temperature rises, and the surface temperature of cement roof and green roof increases. However, due to the difference of heat capacity, the temperature difference of cement roof is the largest, and the change of green roof is the smallest; in the high temperature period in the afternoon, the cooling effect of green roof is the most obvious and enters a stable cooling stage with the passage of time; from 14:00, as the temperature began to drop, the temperature of cement roof decreased rapidly, and the surface temperature of green roof also continued to decline slowly. This surface temperature variation of green roof can form a good cooling surface. Therefore, the green roof plays a positive role in regulating the near ground temperature and protecting the building surface.
