The higher installation costs in comparison to “naked” or gravel roofs are still one of the main arguments against Green Roofs. One reason for this assessment is the lack of information about the economic and ecological benefits of Green Roofs over the entire life cycle of the building. Following you will find some studies which deal with the cost-benefit analysis of Green Roofs.
