There are so many benefits that can be felt with Green Roofs; the following are just a few examples: Green Roofs conserve energy by insulating the building envelope; reducing the need for heating in the winter and cooling in the summer. They also extend a roof's life by protecting the membrane and create biodiversity conservation opportunities. They absorb and filter storm water which reduces local water body pollution and helps prevent the overload of municipal storm water infrastructure. Green roofs also filter air particulates, improving air quality and help to reduce the urban heat island effect (UHI).
