Learn more about this Green Stormwater Infrastructure tool

There’s a plant craze, but did you know that green roofs are a game-changing innovation and green stormwater tool?

What is a Green Roof?

A green roof, also known as a living roof, is a vegetated system installed on the rooftop of a building that helps reduce stormwater runoff. It consists of multiple layers, including a waterproof membrane, a layer of soil, and special plants. They can partially or fully cover a roof.

Green roofs are one crucial Green Stormwater Infrastructure (GSI) tool, which reduce the volume and intensity of stormwater runoff. Acting as natural sponges, green roofs absorb rainwater and reduce the volume on the sewer system, which is particularly valuable during heavy downpours. They help mitigate the risks of flooding, combined sewer overflows, and water pollution.

The benefits aren’t limited to GSI: Green roofs also improve energy efficiency by providing insulation and reducing heat absorption, resulting in lower energy consumption and a reduced urban heat island effect. Additionally, they can create habitats for birds, insects, and other wildlife, contributing to biodiversity.
