For many houses, the layout and design of their roof, as well as the materials used, are fairly common. Roofs can be a huge source of pain for homeowners as well, where sticks and leaves can get on them, and leaks can cause expensive repairs. For the most part, a roof is a roof and you won’t see much variation between homes. However, a new kind of roof is starting to become more and more prevalent wih modern homes: the green roof.

Today, we’re going to discuss what exactly a green roof is and why your next home should incorporate one.

The Basics of a Green Roof

A green roof (otherwise known as a living roof), is a roof that is partially or completely covered in vegetation, planted over a waterproof membrane. These roofs can also contain drainage and irrigation systems.

Green roofs provide several benefits, including absorbing rainwater, providing thermal properties that can help reduce bills, and create a habitat for wildlife (for those used on large buildings in cities), as well as look aesthetically pleasing.

Let’s break these benefits down so you can truly see the benefits of the green roof.

Absorbing Water

Green roofs can be extremely beneficial to not only the homeowners themselves but also the community. Green roofs help to delay the time that runoff occurs by absorbing the majority of rainwater, meaning that green roofs can assist in reducing the volume of overflows in a combined sewer system. Imagine never having to worry about a leaky roof while helping keep your community in tip-top shape as well!

Some green roofs even have the ability to store water for reuse, say for watering plants or cleaning the car.

Reducing Energy Bills

Green roofs actually help to reduce the heat flux through the roof. Basically, your home will be better insulated from conditions outside. So, with less energy needed for cooling and heating your home, you can save money on your monthly energy bills. So, in the summer a green roof will protect your home from direct solar heat. In the winter, the green roof, through its insulation, the green roof minimizes heat loss.

Of course, energy conservation also means a decrease in greenhouse gas emissions.

Habitat for Wildlife

While this can mainly be attributed to green roofs on large, office buildings in cities, we think this is such an important benefit that we want to talk about it.

It’s imperative that we understand that as we continue to expand our cities and build out more into living spaces of local wildlife, we must figure out ways to coexist with our new neighbors. Green roofs have the potential to serve as actual habitats for wildlife like birds. This can help lessen the impact of urban expansion on habitat loss, and just overall incorporate more nature into the concrete jungles around the world.

Who knows, maybe you’ll see some wildlife on your very own green roof!

Unique and Aesthetically Pleasing

While I’m sure there are some folks out there who don’t love the look of green roofs, fans of sustainable homes tend to be.

Green homes are beautiful homes. And there is just something about a green roof, that in addition to the physical benefits it provides, it also provides a sense of calmness and relaxation. Green roofs also look great in wooded areas and other foliage surrounding them.
