Green roofs have recently gained popularity in urban areas. With new buildings going up and green roofs on a majority of them, you may wonder: What exactly is a green roof and what is its purpose?
What is a Green Roof?
In short, a green roof is a rooftop garden or green space. Green roofs provide an ecosystem in urban areas by improving stormwater management, reducing building energy use, and providing a space for urban wildlife.
Benefits of a Green Roof?
Green roofs provide shade, remove heat from the air, and reduce temperatures on the roof surface. Green roofs create an extra layer of insulation in the winter and summer months. In the winter months, green roofs reduce heat loss, and in the summer months, the plants and layers of soil act as a shield from direct sunlight keeping it naturally cooler and reducing building energy usage and cost. A green roof protects the roof against extreme heat, strong winds, and temperature fluctuation. This defense against the elements can double or triple the lifespan of roofs.
Green roofs can reduce and slow stormwater runoff. The moisture retention mats absorb rainwater, which allows the water to be released through evaporation and stabilizes groundwater levels.
A majority of buildings allow roof access to their tenants so your green roof can be used as an amenity to host meetings and events. Some roofs can also be used as a natural habitat area due to urban development and loss of green space for wildlife.
Green roofs are a worthy investment for any property and will provide several benefits. With a green roof, you can utilize the space you already have to not only protect your building but also help the environment.
