The Benefits of Eco-friendly Green Roofs
Green roofs are becoming much more popular in this day and age because of the many great benefits. In this article, you’ll find an outline of some of the benefits of green roofs and things to take into consideration if you’re thinking of starting one of your own.
Green roofs, also called living roofs, are roofs that are covered either partly or entirely in plants or grass. The growing vegetation is planted over a waterproofing membrane and may also contain multiple layers including a filter sheet, drainage layer, protection mat and root barrier.
Not only do green roofs enhance the look of your home, they also provide many eco-friendly benefits. Green roofs absorb and retain rainwater which reduces the chance of flooding. They also absorb sunlight which helps keep the interior of your home cooler. Sunlight absorption also increases efficiency of solar panels, making them more effective. Having a green roof is also a great way to improve the air quality around your home, reducing the number of polluting air particles. They can extend the lifetime of your roof, sometimes even doubling or tripling it. Normal roofs have an enormous amount of sunlight shining on the roofing material which causes it to crack and become brittle. This can save a lot of money.
More benefits include decreasing outside noise, due to the sound barrier the green roof creates. In cities, green roofs on buildings can help keep temperatures down by counteracting the urban heat effect.
If you’re interested in building your own green roof, there are some important things to consider. You’ll, of course, need to consider the location. The best location for a green roof is below a higher roof, so that the vegetation can benefit from the higher roof’s rainfall runoff accomplished by installing a “rain chain”.
Another important consideration is the weight of the components of the green roof. If the structure of your roof is not sturdy enough, you may have to consider extra reinforcement before installing your green roof. You’ll also want to consider the slope of your roof. The easiest type of roof to install your green roof on is a flat roof. Low sloping roofs can be used as well, but steeper sloped roofs require reinforcement systems.
