The layers of a green roof must like any roof accommodate drainage and protect the building from the elements with a waterproof membrane.

It is made of a waterproofing layer a root barrier a drainage system and growing medium for the plants. The vegetation on a green roof cools the surface and reduces heat from the air through evapotranspiration.
