What Are The Things You Need To Consider In A Green Roof Design?

When it comes to installing a green roof, you don’t just dump all the layers that can turn a concrete roof into an urban mini forest. Actually, the first thing you need to consider before you do any kind of work is to have a design made for you. This isn’t just for aesthetic purposes.

A green roof with a proper design can mean the difference between a roof that can adversely affect your building in the long run, and a roof that does not. But who should design your green roof? You should leave it in the hands of professional green roofers. If you do a local search on Google, you should be able to find companies out there that specialize in that kind of work.

Following The Design Process

Designing a green roof starts with the design of the finished landscape in a 3D model. The kind of design that results depends on what you want in a roof. Do you want a biodiversity roof that will support a mini jungle? Do you want a simple intensive or extensive roof?

A simple intensive roof is thick and is at least five inches. A simple extensive, on the other hand, is thin and is at least 0.75 inches. Intensive means you can support a wide variety of plants although not as varied as a mini jungle. Whatever you choose, there are some basic requirements you need to fulfil to in order to sustain your green roof, like a balance between moisture and drainage as well as aeration to the root systems, and all these things are considered in the design.

Inclusion of Specific Components

Once the type of roof and the plants have been decided on, the specific roof components can then be proposed.

One of the most vital aspects of design is protection for the building’s construction. A green roof cannot, in any way, affect a building since so many other factors can affect the building. In general, a green roof can only be done on a flat roof, and is installed on roof pitches between 1 to 30 degrees.

A green roof design ultimately seeks to meet the requirements for drainage and irrigation, water storage, sufficient depth to support the green roof media and the weight of the resulting roof. It also seeks to comply with building regulations on safety and fire access, and other rules.
