Vegetated roof

Vegetated roof

A roof that is partially or completely covered with vegetation and soil, or a growing medium, planted over a waterproofing membrane. These roofs reduce heating and cooling loads, reduce the urban heat-island effect, increase roof lifespan, reduce storm-water runoff, filter pollutants and CO2 out of the air, filter pollutants and heavy metals out of rainwater, and increase wildlife habitat in built-up areas. Also referred to as a green roof, eco-roof, or living roof.

On the down side, green roofs are a costly undertaking with many complexities ranging from a building's load capacity; usage (will it only be viewed or be used as garden space?); what part of the roof you will green (exposures will vary greatly); whether you install an intensive green roof which is thicker, deeper, heavier and supports more plants, but requires more maintenance; or extensive which is shallower, lighter and more minimal maintenance; whether you opt for a modular vegetated roof, an alternative to the built-in roof where mobility makes it easier to do roof repairs and is quicker to achieve completion (but costs somewhat more); what plants will be used; and what systems will be used for root barrier, drainage and irrigation.
As for solutions, Malone says, "The seamless integration of outdoor space planning with the functional considerations of building structure, architectural detailing, wayfinding, and better understanding of the end user's needs are paramount."
