Green Roof Defined

This is most noticeable in intensive green roofs since there is a thicker and more consistent layer of soil which provides a higher insulating value.

Green roof defined. Green roofs can provide a wide range of public and private benefits and have been successfully installed in countries around the world. There are two basic types of green roofs. A green roof is a supplemental roofing system that covers a conventional roof with a layer of vegetation. They fall into three main categories extensive intensive and semi intensive.

These roofs will have grasses ground covers flowers shrubs and even trees. Note that it is not like a traditional roof garden in which planting is done in free standing containers as well as planters that are placed on an easy to access roof terrace. A green roof is a layer of vegetation planted over a waterproofing system that is installed on top of a flat or slightly sloped roof. Green roofs can help reduce energy costsfor a building by acting as another layer of insulation between the inside and outside of the roof.

Green roofs are also known as vegetative or eco roofs. A roof covered with vegetation designed for its aesthetic value and to optimize energy conservation. A green roof is a green space that is created by adding various layers of plants and a growing medium to the top portion of a traditional roofing system. A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium planted over a waterproofing membrane it may also include additional layers such as a root barrier and drainage and irrigation systems.

Intensive green roofs are widely used on commercial buildings where owners want to have large green areas that incorporate all sizes and types of plants. Container gardens on roofs where plants are maintained in pots are not generally considered to be true green roofs although. These are not typical point loaded roof gardens as their live load is evenly distributed partially or fully over the roof surface. This green space could be below at or above grade but in all cases it exists separate from the ground.
