A green roof provides many advantages. It lowers roof surface temperature, retains storm-water and helps purify the surrounding atmosphere. As an insulator it lowers heating, ventilation and air conditioning (HVAC) costs, protects the underlying roof deck from UV radiation and weathering, and reduces heat dilation of roof components.
