Heat-island phenomenon has become obvious in urban area of recent years. Rooftop greening become a specific and effective measures of alleviating this problem. Maintenance easily vegetations such as sedam are applied to rooftop greening products initially, but recently there are many products using turf because it is important to evaporate from vegetations for reducing sensible heat flux of rooftop. Many previous studies mainly dealt with vegetations on the ground, but it's conceivable that rooftop greening products possess different characteristics from natural ones because of specific soil, watering system and so on. This paper presents heat and water budget characteristics of rooftop greening products based on long term actual measurement, reduction effect of heat-island by provisional estimation.
