A growing trend in so many city centers, green roofs help to restore the ecological benefits which have been lost in a variety of ways, such as providing a micro-habitat for birds and insects. Green roof design and technology is a practical and worthwhile method for addressing some of our environmental concerns due to urban sprawl.

A green roof assists with city stormwater management, relieving overstressed sewer systems by reducing and delaying stormwater runoff and absorbing pollutants in rainwater. Heavy metals found in rainwater, such as lead, copper, and cadmium are reduced in the runoff, making a difference in water quality through drainage channels that run into nearby waterways. Sediment transport and soil erosion is further reduced by lessening and slowing down the rate of runoff.

Natural landscapes help reduce the urban heat island effect by lowering air temperatures. Artificial surfaces, such as asphalt and concrete cause air temperatures to rise in crowded urban areas. Green roofs also filter airborne dust and toxins. Carbon dioxide, for example, is absorbed through the grass and/or natural foliage, working to help clean the air. Even very small urban roof areas can make a difference. Sponzilli Landscape Group’s goal is to help to make that difference with our green roof designs.

A most important benefit of a living roof is the reduction of heating and cooling costs. Due to increased insulation, the building will stay cooler in the summer and warmer in the winter, reducing energy costs and consumption.
