Extensive green roof systems are the most common type of green roof. The planting media is between 1" – 5". Most extensive green roofs are not for public access and are used primarily for their water conservation properties.
Commonly know as “garden roofs,” intensive green roofs are more complex than extensive green roofs. Planting media for intensive green roofs are at least 12" deep, which allows for greater plant diversity. Intensive green roofs are typically public places that incorporate patio areas. Examples could range from private rooftop patio to the largest green roof, Millennium Park in Chicago.

Social and Aesthetic Benefits
Green roof systems have many social benefits from improved livability and improved physical and mental health from exposure to nature. They also provide an increased sense of pride and beautification.
Green roofs are much better looking than asphalt gravel or tar and open up a wide array of possibilities as far as use of space by incorporating patios, gardens and vistas.
Green roofs have many environmental benefits. Water conservation through reduction of storm water runoff is the major benefit of green roof systems. The plants and soil in the green roof system acts like a sponge and absorbs excess rainwater. Green roof systems can reduce runoff by up to 90% thus reducing the impact of new buildings on local municipal drainage systems. Green roofs also help the urban heat island effect by cooling the air. Green roof systems also help with noise reduction and fire prevention.
