Intensive green roofs, on the other hand, are more like elevated parks. In addition to frequently having paths and benches, they may sustain a large range of flora, such as trees and shrubs. Intensive roofs require more maintenance, deeper soil, and a robust waterproofing system due to their complexity and the heavier load.

• Environmental Benefits

Green roofs play a critical role in environmental sustainability. They reduce stormwater runoff, which can decrease urban flooding and water pollution. By absorbing rainwater, these roofs help manage peak flow in sewage systems during heavy rainfall.

Additionally, green roofs are excellent insulators for buildings. They assist in reducing the demand for cooling in the summer and heating in the winter, which lowers energy consumption and expenses. Their capacity to absorb and filter air pollutants and carbon dioxide greatly improves urban air quality and reduces the urban

heat island effect, where urban environments can become significantly warmer than their rural surroundings due to human activities.

• Biodiversity and Ecosystems

Beyond its advantages for the environment and the economy, green roofs also greatly enhance biodiversity by serving as habitats for a variety of bird, bee, butterfly, and other animal species, particularly in metropolitan areas with limited green space. This creation of new green habitats can help preserve biodiversity in densely populated areas.

Roofing Materials with Improved Durability

The durability of roofing materials is crucial for the longevity and protection of a building. Recent advancements in material science have led to the development of roofing materials that are not only more durable but also environmentally friendly.
