Green Roof From Above

Types of green roofs.

Green roof from above. For intensive green roof profiles a drain restrictor may be used to retain water in the base of the profile for subsequent plant transpiration. Green roofs provide shade remove heat from the air and reduce temperatures of the roof surface and surrounding air. A green roof or rooftop garden is a vegetative layer grown on a rooftop. Green roofs can provide a wide range of public and private benefits and have been successfully installed in countries around the world.

Germany where about 10 percent of roofs are green is the leader. A green roof moderates the heat flowing through the roof. This green space could be below at or above grade but in all cases it exists separate from the ground. In truth this should be the future as this approach provides the greatest range of benefits.

The smartest green roof is one where the green roof element above a blue roof is a biosolar roof a green roof that houses solar panels. An intensive green roof is a deeper typically greater than six inches heavier system designed to sustain complex landscapes. This helps to reduce temperature fluctuations caused by solar radiation. Especially if it is designed specifically for biodiversity.

Green roof development involves the creation of contained green space on top of a human made structure. Due to the excessive water amounts associated with green roofs the membrane must be strong enough to support this water weight and to not let it seep through. The additional thickness of the growing medium provides extra thermal insulation. A green roof is a roof that is partially or completely covered with vegetation and soil planted over waterproofing membrane.

A membrane is the bottommost layer of a green roof and is the main separation between the green roof above and the structural supports below. Greening a roof is not simple or cheap. Over a black roof flat.
