Installing a green roof provides a lot of environmental, social, and economic benefits while reducing the negative impacts brought upon by urbanization and population growth. But what is a green roof?

A green roof uses plants such as lichens and grasses as a cover for your roof. The process of installation involves waterproofing your existing roof, creating a drainage system to ensure that the plants will cause no damage and application of a root repellent system. A filter cloth with a growing medium will then be placed on your roof. Lastly, installers will place the plants securely on your roof.

The initial expense of installing a green roof is quite high, but it is a worthy investment that you and the community can benefit from in the long run. Aside from having a pretty little garden on top of your house or building, having a green roof can be very rewarding.
