Green roofing is an innovative way to save energy and beautify cities. Instead of dark roofing, green roofing provides essential color, vegetation, and insulation. Learn more about the benefits of green roofing and why it is becoming so popular in NYC and other cities across the country.
A green roof is a roof that is covered in plants, which reduces stormwater run-off and lowers cooling costs. Find out how a green roof can help the environment.

Green roofs are roofs that are substantially covered with living plants. Although historical and archaeological evidence suggests that green roofs have been built for more than three thousand years, widespread acceptance has always been limited by the structural cost of supporting heavy soils and by the technical challenges of low-slope waterproofing. Recent advances in membrane waterproofing technology combined with the development of lightweight thin-profile green roofs have finally made green roofs practical for most new construction: there are now more than one billion square feet of lightweight green roofs!

A green roof, or rooftop garden, is a vegetative layer grown on a rooftop. Green roofs provide shade and remove heat from the air through evapotranspiration, reducing temperatures of the roof surface and the surrounding air. On hot summer days, the surface temperature of a green roof can be cooler than the air temperature, whereas the surface of a conventional rooftop can be up to 90°F (50°C) warmer.1
Green roofs involve growing plants on rooftops, thus replacing the vegetated footprint that was destroyed when the building was constructed.
