NEWS – According to recent research, green roofs treated with mycorrhizal fungi foster a more diverse soil community that is more likely to support long-term green roof sustainability


Green roofs, also known as living roofs or eco-roofs, are roofing systems that incorporate vegetation, soil, and sometimes other components like drainage and irrigation systems. Instead of a traditional roof covering, green roofs have a layer of growing medium that supports plant life

There are two main types of green roofs: extensive and intensive.

  1. Extensive Green Roofs:
    • Low Maintenance: These roofs have a thin layer of soil and support low-growing, hardy vegetation such as sedum or moss. They require minimal maintenance and are lightweight.
    • Environmental Benefits: Provide insulation, reduce stormwater runoff, and improve air quality.
  2. Intensive Green Roofs:
    • Greater Depth: These roofs have a thicker layer of soil, allowing for a more diverse selection of plants, including shrubs and even trees. As a result, they can support more complex ecosystems.
    • Recreational Spaces: Intensive green roofs can be designed for recreational use or gardening, creating more versatile and usable spaces.

Benefits of Green Roofs:

  1. Environmental Benefits:
    • Stormwater Management: Green roofs absorb rainwater, reducing runoff and helping to manage stormwater.
    • Air Quality: Plants on green roofs can help filter pollutants from the air.
    • Temperature Regulation: Green roofs provide insulation, reducing energy consumption for heating and cooling.
  2. Aesthetic and Recreational Value:
    • Aesthetics: Green roofs can enhance the visual appeal of buildings and urban landscapes.
    • Recreational Space: In the case of intensive green roofs, they can provide usable outdoor spaces.
  3. Energy Efficiency:
    • Insulation: Green roofs can act as a natural insulator, reducing the need for heating and cooling.
    • Temperature Moderation: They help regulate indoor temperatures, reducing the urban heat island effect.
  4. Biodiversity:
    • Habitat: Green roofs can support diverse ecosystems, providing habitats for birds, insects, and other wildlife.
  5. Longevity of Roofing Material:
    • Protection: The vegetation layer can protect the roofing membrane from UV rays and temperature fluctuations, potentially extending the lifespan of the roof.

The adoption of green roofs is influenced by factors such as climate, building design, and local regulations. Many cities around the world encourage or incentivize the installation of green roofs as part of sustainable urban development initiatives
