How Does A Vegetated Roof Work

Vegetative roofs can absorb a portion of the sound that otherwise bounces off hard roofing surfaces.

How does a vegetated roof work.

Green roofs provide shade remove heat from the air and reduce temperatures of the roof surface and surrounding air. A traditional vegetated roof has the five layers of vegetation engineered growing retention drainage and root barrier. A green roof or rooftop garden is a vegetative layer grown on a rooftop. 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.

Using green roofs in cities or other built environments with limited vegetation can moderate the heat island effect particularly during the day. They fall into three main categories extensive intensive and semi intensive. Modern vegetated roofs bring nature back to the cities for a plethora of benefits using available space on rooftops mostly for swm benefit. The added weight of a vegetative roof results in an increased degree of sound insulation.

Vegetative roofs have important acoustical benefits especially for higher frequency sounds. As the name suggests vegetative roofs are a design in which plants are used to create a green space on top of a building. See the referenced ghent university study for more information. Green roofs are also known as vegetated roofs or eco roofs they have become more popular in recent years which is unsurprising because of the incredible ecological benefits they have.
