What is roof?
The term "roof" refers to a covering that is often put on top of a structure to give shelter from the elements, particularly rain and sunshine. There are essentially two different kinds of roofs, which include:
Standard roof.
An eco-roof.
A layer of vegetation or growth media that is functionally planted on top of a flat or slightly inclined roof is known as a green roof, also known as a living roof. Typically, installing a green roof would cost twice as much money as doing so for a conventional roof.
