Understanding The Basics
Intensive Green Roof
Intensive green roofs require the deepest soil and have the largest impact on the structural design. In addition, these assemblies can accommodate all types of plantings including bushes, large shrubs, and trees. Intensive systems allow the designer to create a captivating park-like setting, providing beautiful amenity spaces for the building occupants while also managing the municipal stormwater management requirements.
Extensive Green Roof
Extensive Green Roofs are shallow systems that typically utilize succulents to form a beautiful variegated vegetative cover that transforms through the seasons. These systems offer the most natural and cost-effective infrastructure to reduce stormwater run-off from buildings at the source. In addition, an Extensive Green Roof would be a home for plants with special adaptation to extreme site conditions and high regeneration capacity, lowering maintenance requirements, and the need for permanent irrigation systems.
*All green roof systems require an effective maintenance program to minimize weed pressure that can choke out the vegetation and deteriorate the visual beauty and effectiveness of the stormwater system.
