An Architect S Guide To Green Roofs Architizer Journal As a general rule most modern green roofs are comprised of seven distinct layers: waterproofing membrane. protects the roof itself and prevents water from leaking into the building. root barrier. flexible, nontoxic layer that prevents plant roots from penetrating the waterproofing membrane. drainage layer.

A green roof system is an extension of the existing roof which involves, at a minimum, high quality waterproofing, root repellent system, drainage system, filter cloth, a lightweight growing medium, and plants. green roof systems may be modular, with drainage layers, filter cloth, growing media, and plants already prepared in movable, often. One of the main considerations of a green roof is its load bearing capacity. intensive green roofs, with increased layers and ability to retain large amounts of water, make this consideration especially important. it also makes retrofitting an existing structure with a green roof more expensive than designing a green roof into a new building.

With the decking in place, here are the steps to installing a green roof: install waterproof membrane. install a monolithic type waterproof membrane (rubber or plastic) on top of the roof decking. Extensive green roofs are generally made up of a very thin layer of soil or other planting medium with shallow root plants like sedum, mosses, and grasses. the soil is usually not more than 5" deep and is sometimes contained by a tray system, which provides a barrier to excessive growth, protects the roof membrane, and also interlocks the.
