How Does A Vegetated Roof Work

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.

How does a vegetated roof work.

Modern vegetated roofs bring nature back to the cities for a plethora of benefits using available space on rooftops mostly for swm benefit. A green roof or rooftop garden is a vegetative layer grown on a rooftop. Using green roofs in cities or other built environments with limited vegetation can moderate the heat island effect particularly during the day. The added weight of a vegetative roof results in an increased degree of sound insulation.

Green roofs are also known as vegetative or eco roofs. 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. They fall into three main categories extensive intensive and semi intensive. Vegetative roofs can absorb a portion of the sound that otherwise bounces off hard roofing surfaces.

Typical green roofs consist of multiple layers including a durable waterproof foundation a root management system drainage layers and some type of growing medium. They are known to extend the lifespan of the roof of a building by protecting it against uv radiation and other elements such as snow and ice. Green roofs provide shade remove heat from the air and reduce temperatures of the roof surface and surrounding air. See the referenced ghent university study for more information.
