General Benefits of Green Roofs – Water Runoff Reduction

September 12th, 2019

With a climate that is seemingly producing more spells of wet weather, green roofs are proven to play a key role in helping to significantly reduce the surface runoff volumes and rates of rainfall leaving roofs.

As a proven control mechanism in the SUDS (Sustainable Drainage Systems), green roofs can play an important role in helping to reduce the potential for flash floods as a consequence of intense rainfall events.

Rainfall Rising Globally

With rainfall amounts on the rise globally, it’s a crucial time to examine how cities can retrofit their existing building infrastructure to alleviate flood damage and deal with stormwater in a more sustainable manner.

Green infrastructure technologies, such as permeable pavements, bioswales, cisterns and green roofs, are now commonly recommended to confront extreme weather events.

Green roofs for stormwater management

Green roofs are a green infrastructure (GI) option that can be applied to virtually any rooftop given weight load capacity. The benefits of green roofs extend far beyond their obvious aesthetic appeal.

A study done by University of Toronto civil engineer Jenny Hill and co-researchers at the school’s Green Roof Innovation Testing Lab (GRIT Lab) showed that green roofs have the capacity to capture an average of 70 per cent of rainfall over a given time, relieving underground storm-water systems and releasing the rainwater back into the atmosphere.
