Benefits of Green Roofs

There are many benefits to green roofs which make them attractive to building owners today. One of the biggest benefits to green roofs is reducing storm water runoff. As urban sprawl continues, many areas can no longer accommodate the volume of water discarded off of roofs, roads and other impervious surfaces. Green roofs hold rain like a sponge and allows nature to dissipate the moisture naturally rather than rely on aging storm sewer systems. Green roofs also reduce urban heat islands by reducing roof top temperatures. The surface of a conventional black roof can reach 180°F. Vegetation protects the roof from extreme temperatures and works to lower the temperature of our urban environments. Green roofs also reduce the energy requirements of a building. By reducing the ambient temperature of the roof's surface, green roofs slow the transfer of heat into the building. This reduces the cooling requirements of the facility. Green roofs also provide insulation to the structure and therefore also reduces the heating requirements of the facility. Other benefits include reduces air and noise pollution, provides urban micro-climates, provides useable outdoor patio spaces, and provides protection from heat, ultraviolet radiation, and physical abuse resulting in a longer lasting roof system.
