Green roofs have been steadily gaining in popularity since 2004. The biggest jump happened just last year when the North American green roof industry grew by an estimated 115%, according to a study by Green Roofs for Healthy Cities.

It’s estimated that at least 16 million square feet of green roof space was installed in 2011. Just 4.3 million square feet was installed in 2009.

There is a fairly even split between private and public green roof installation.
Future growth.

Green Roofs for Healthy Cities says the future growth potential for green roofs is enormous.

There are billions of rooftop square feet in North America that present opportunity for green roof installation.

There are numerous large metro markets that have yet to establish policies and/or incentives to encourage green roof installation.

The Green Roof Professional (GRP) accreditation program is also becoming more popular. There are more than 500 GRPs across North America today. This high level of education and discipline helps bolster consumer confidence in green roofs.
Benefits of green roofs.

According to Green Roofs for Healthy Cities, there are numerous environmental benefits to having a green roof system on your building:

  • Stormwater management
  • Increase of biodiversity
  • Moderation of urban head island effect
  • Improvement of air quality
  • Improvement of aesthetics in the public realm
  • Addition of new amenity spaces
  • Local job creation
