Abstract: Green roofs (GRs) offer several environmental, social, and economic benefits while numerous barriers are limiting their adoption. This study covers two gaps in the literature: first, the lack of indicating separate hindrances to different types of GRs; second, the dearth of research related to the hindrances on GR adoption in any climate of Iran. This research aims to identify and analyze the importance of hindrances to GR adoption by considering the two major types of GRs using the Fuzzy Delphi Method (FDM) and Fuzzy Analytic Network Process (FANP), respectively. The results indicated that eight out of twenty-five identified hindrances to GR adoption were rejected using FDM. Moreover, it was found that although financial hindrances are significant for both types of GRs, public awareness is the most important hindrance to extensive GR adoption. As the first research of its kind in a semi-arid climate of Iran, the findings of this research provide an insight for the researchers and policymakers regarding the hindrances to GR adoption for further research and action.
