A garden roof with lightweight medium to support low growing plants. It provides evaporative cooling, converts carbon dioxide to oxygen and reduces stormwater runoff. Green roofs can also include reflective roofs (cool roofs).
a flat roof, usually, that has plants growing in a thin layer of soil, and works much the same as any roof
a living biological community of plants and microorganisms that provides an environmentally sound alternative to a traditional roof system
a living, vegetated roofing alternative that helps to clean and manage stormwater, reduce air pollution, create livable habitat, and reduce the negative impact a building has on a site
an extension of the existing roof
a roofing assembly that allows for the dispersion of vegetation across all or part of a roof surface
a roof substantially covered with vegetation
a thin layer of natural plants growing on a conventional roof
a wild garden of grasses and herbs planted on a suitable surface, usually on an urban house
Also known as rooftop gardens, green roofs are planted over existing roof structures, and consist of a waterproof, root-safe membrane that is covered by a drainage system, lightweight growing medium, and plants. Green roofs reduce rooftop and building temperatures, filter pollution, lessen pressure on sewer systems, and reduce the heat island effect.
A roof constructed of various landscaping materials.
A roof with plants growing on its surface, which contributes to local biodiversity. The vegetated surface provides a degree of retention, attenuation and treatment of rainwater, and promotes evapotranspiration. (Sometimes referred to as an alternative roof).
A green roof is a roof of a building that is partially or completely covered with vegetation and soil, or a growing medium, planted over a waterproofing membrane. The term does not include roofs which are merely colored green, as with green shingles. It may also include additional layers such as a root barrier and drainage and irrigation systems.
