Green roofing isn’t necessarily about lush green plants, it is also about blue: water.
Green roofing describes the potential for storm water detention using the roof system. Covering a roof surface with a lightweight Extensive Green Roof System is part of a total Low Impact Development approach for protecting our nations fresh water resources. The average 4″ extensive green roof can absorb between 60 to 90% of a 1″ storm event. The more successful the planting establishment, the more effective the storm water detention. A well built system could delay the runoff of over 6,200 gallons on a 10,000 sq ft roof.
Green roof media can only hold a certain amount of water, so the drainage component moves excess water away from the plant roots.
