An extensive green roof system is characterized by its vegetation, ranging from sedums to small grasses, herbs and flowering herbaceous plants, which need little maintenance and no permanent irrigation system. The growing medium depth for an extensive green roof system is typically 6 inches or less. These systems are ideal for efficient storm water management with low maintenance needs. Extensive green roofs are very cost efficient.
