Answers to Your Questions about Green Roof Installation on Your Commercial Building

Posted on: 25 April 2016


A green roof, also commonly called a living roof, is a unique, environmentally-friendly type of roof. It involves placing living plants on the top of your building to create a roof out of these materials. If you are thinking of installing this type of roof on your commercial building, you may have many questions. Here are a few frequently asked questions about green roofs.

Can a Green Roof Be Installed on a Commercial Building?

Green roofs can be installed on both flat and sloped commercial or residential roofs. They are generally easier to maintain on flat roofs, because you don't have to worry about soil erosion. And luckily, most commercial buildings have flat roofs. As such, this may be a great fit for a commercial building.

What Are the Benefits of a Green Roof?

If you are considering installing a green roof, you likely want to know about its many benefits. One benefit to installing a green roof is that you are installing a unique roof. This can help your building stand apart from other similar buildings. And if you have roof access, the living roof can be turned into a garden area where your employees can relax on their breaks or eat their lunch in a quiet environment.

There are also many environmental benefits to installing a green roof. Plants on a green roof can help filter out pollution, making air cleaner. A green roof is energy efficient, reducing the amount of time you have to run the air conditioner or heater in your building. And a green roof is made from many different environmental-friendly materials such as recycled plastic membranes, plants and growing mediums.

What Can You Plant on a Green Roof?

As you think about installing a green roof, you may start to wonder about what types of plants will be placed on the roof. Unfortunately, there is not a one-size-fits-all answer to this question. There are many different factors that determine what plants should be placed on your roof. One of the factors that plays a role is how much water you get in your area. You need to use plants that can adequately absorb the amount of water that falls during typical rainstorms. Likewise, if you live in an area with little rainwater, you need to select drought-tolerant plants.

Another factor that comes into play when selecting plants for use on your green roof is how much sun your building gets. If you have a small commercial building, it may be overshadowed by larger buildings. In this case, you will want to select plants that thrive in shady conditions. But if your building gets a lot of sun, you need plants that can survive the sun.

The last factor that plays a role in the type of plants that can be placed on a green roof are the types of root systems a plant, shrub or grass has. You don't want plants with large root systems. These can grow through your waterproof membrane and break it. You need plants that have root systems that grow sideways, rather than straight down, and are flexible. Mosses, grasses, and herbs are examples of great choices for a living roof.

Can the Average Building Owner Install a Green Roof Themselves?

The last question you may have about green roofs is whether you can install one yourself. Installing a green roof can be complicated. It is much more complex than simply planting a garden atop your current roof. A waterproof membrane needs to be installed to ensure any water that seeps through your plants and soil does not penetrate your roof. The right amount of soil needs to be used so that your roof does not become so heavy that it collapses. And the types of plants that are installed are important, to ensure that water that falls is absorbed by these plants. As such, the average commercial building owner should not attempt this project on your own. If you are considering installing a green roof, hire a company like Central States Roofing to assist you with all of these aspects. This will ensure your roof is properly installed and no problems will occur in the future.

A green roof is a great way to reduce the carbon footprint of your business. If you are considering this type of roof, you may have many questions. Getting answers to the questions you have about this type of roofing will help you decide if it is ideal for you and your commercial roof.
