What Are The Advantages And Disadvantages Of A Green Roof?

  1. Decrease pollution and improve air quality in cities. The vegetation absorbs toxic substances and releases oxygen into the atmosphere.
  2. Helps to combat the effect of heat in large cities.
  3. Improves the thermal insulation of the building. It protects against high temperatures in summer and helps to maintain the internal temperature in winter.

  7. Helps to decrease the temperature of the external micro and macro environments.
  8. Reduces energy consumption, and improves energy efficiency due to the reduction of temperature in the internal environment, reducing the need for refrigeration.
  9. Increase in biodiversity, attracting birds, butterflies, and others.
  10. Beautify the building and the city.
