Intensive green roofs are designed to support a wide variety of plants, including shrubs and small trees. They typically have a deeper soil layer, often exceeding 12 inches, which allows for greater plant diversity and more complex ecosystems. These roofs require regular maintenance, including irrigation and fertilization, to thrive. Due to their weight and complexity, intensive green roofs are usually installed on buildings that can support the additional load. They provide benefits such as improved insulation, reduced urban heat, and enhanced biodiversity, making them a valuable component of sustainable urban design and green architecture.
