You're planning your new home and you want it to be environmentally friendly. Since you're building it yourself, you have the opportunity to go as green as you want. You've heard about green roofs, but you're not sure you want to go that green, especially since it involves growing plants on your roof. You might have even heard some negative information about them. Before you say no to a green roof, take a look at some of the common misconceptions.

They're a New Fad

If you thought that green roofs were just a passing fad, you thought wrong. Green roofs have actually been around for several decades, if not centuries. In Europe, people have been utilizing green roof technology for since around the 1970s, according to one report. The same study shows that many ancient homes used plants and grasses on their roofs as a way to protect their homes from the environment.

They Leak

You might have heard that green roofs leak. Any type of roof – whether green, tile, or asphalt shingle – will leak if it's installed incorrectly. However, a properly installed green roof will not leak. When discussing installation with a roofing company like Dome Construction Company, it's important that you take the following items into consideration.

Waterproof Membranes

To protect your home from leaks, you'll need a waterproof membrane installed directly on top of the wood sub-structure of your roof.

Root Barriers

The root barrier will prevent roots from growing too deep. Without the barrier layer, roots may be able to grow through the wood sub-structure and into your home.

Perimeter Flashing

The perimeter flashing will help keep your plants in place and prevent moisture from leaking under the edges of your roof.

They're Hard to Irrigate

If you're thinking of climbing on the roof with a hose each day, then yes, a green roof is hard to irrigate. Luckily, green roofs can take care of their own moisture if you include the right plants - such as succulents. Using the right type of soil is also important.

For instance, some soil additives have special polymers that help retain moisture. Using polymer-type additives will allow the soil to utilize more of the moisture it receives from rains, which will reduce – or eliminate – the need for special irrigation for your green roof.

If you're trying to design a home that's good for the environment, you might want to consider a green roof. If you have questions or concerns about them, be sure to speak to your roofing contractor.
