This study evaluated performance for runoff management of the Blue roof and Green blue roof comparing monitoring data measured at two low impact development (LID) facilities and control roof in Seoul metropolitan area. From the results these two roofs proved as suitable stormwater management practices in urban areas. For this purposes, Blue roof and Green-blue roof were installed at Seoul City Hall Annex Seosomun and Cheong-un middle school respectively. The data used for this study were collected during the actual storm events of more than 30 mm/hr and 60 mm/hr rainfall intensity in July and September 2014 at green blue roof and blue roof. During different actual storm events, rainfall runoff outflow was measured from blue roof was 0.45 l/s as compared to common roof where outflow was 1.55 l/s. While on the other hand, the outflow from green blue roof was 0.1 l/s to as compared to control roof where the runoff outflow was 0.3 l/s. Results also indicated the peak flow reduction in both types of roofs. From the results, it was found that Green blue roof is capable of handling effectively long duration rain events than blue roof. However, the blue roof is inexpensive than green blue roof and suitable option for retrofitting in urban areas. These results also revealed that Blue roof and Green blue roof could be applied to urban buildings as the suitable management practices for rainfall runoff management in urban areas. At the end, from theoretical analysis some suggestions are also made which could be apply for the more safe sustainable drainage system of an urban area.
