A green roof is a living roof of a building made from growing vegetation. The roof is covered with a waterproofing membrane, growing substrate such a soil or mulch, and then seeded.
Green roofs increase air quality and filter pollutants, provides insulation to the roof reducing energy consumption, reduce noise, can provide food and habitat for birds and other wildlife.
Green roofs can be designed for a wide range of maintenance requirements, while some are designed aesthetically as recreation, dining, or community garden spaces.
Green roofs are often installed with the help of a blower truck to pneumatically move material from the ground to the roof. This eliminates the need for wheelbarrows, construction cranes, and other heavy duty equipment. The blower truck can install rooftop soil and mulch efficiently.
