District 5 of Isfahan, regarding issues such as improper distribution of green spaces, lack of barren lands, air pollution, noise pollution, etc., and, due to its potential, can use green roofs to attain ecological city goals. This study aims to assess the feasibility of green roof development to achieve an ecological city in the study sample. The research method is applied in terms of purpose, descriptive-analytical interms of nature, and quantitative in terms of paradigm. The data collection method was documentary and field study through a questionnaire. The statistical population of the study is citizens over 15 years old. In 2016, their number was 126,530, out of which 375 were selected by cluster sampling. Based on the purpose of the research, 55 items were designed in the form of 11 ecological city indicators and according to the research hypotheses. The validity of the questionnaire was confirmed as face validity from the perspective of academic experts and its reliability was confirmed by Cronbach’s alpha (more than 0.7). Regarding the results attained from the citizens’ point of view, there is the necessary preparation for the construction of green roofs to achieve an ecological city in this region. Also, there is a significant relationship between raising the level of culture and awareness of citizens living in the region and participation in the development of green roofs in the region (0.364) and there is a significant relationship between the application of incentive criteria and the desire to develop green roofs (0.232).
