What is a green flat roof?

A green roof is a roof that has been layered with turf or grass. They are available in pitched options or flat options. A pitched option is a roof that slopes, whereas a flat green roof is exactly as it sounds – flat.

A green roof is also known as a living roof. The reason for this is because the roof is covered in a living, growing substance, grass. This is usually supported by vegetation or some other form of growing medium.

They tend to be planted over a waterproof membrane (after all, they are roofs, and so they need to keep your building safe from leaks). There may even be additional layers featured on your green roofs such as irrigation systems and even a root barrier.

The reason people install green roofs can vary. For example, some people use them as a way of absorbing the rainwater that falls. They may also be installed to help provide insulation to the building underneath. Then, of course, there are the environmental benefits such as providing a natural habitat (this is especially important in a city).

The benefits of a green roof are many, and we will be exploring this in more detail in the next section of the article. For now, suffice that green flat roofs (and pitched green roofs) are very popular and for good reason.

A green flat roof can be installed on a number of different existing buildings such as retrofit or redevelopment structures. However, it is more common to see them featuring on new builds. In fact, in some places around the UK, it is expected that green roofs at least be considered as an addition to new builds, particularly in major cities such as London.

The great thing about a green roof is that it can be as big or as small as you like. As such, they can be installed on something as small as a garage, and as big as a skyscraper as well as any large commercial buildings, and even some industrial buildings.
