With global warming and pollution being ever-present topics on the news, it is important for everyone to contribute to making the world a cleaner place. One way to do this is to use ecologically friendly materials when building your home. The wave of the future is green roofing.
A green roof is a roof that is covered with vegetation. Essentially a rooftop garden, green roofs were developed in the 1960s in Germany, and have become quite popular in many European countries. It is only recently however, that green roof technology has begun to catch on in the U.S.
A green roof is excellent for city dwellers who often lack green space such as a yard or a deck. The addition of a green roof can provide a space to express one’s creativity, and bring nature back to the city. In fact, by planting native vegetation, you can invite insects, birds, and butterflies that would otherwise have nowhere else to go. As an added benefit, green rooftops are aesthetically pleasing and offer a visual contrast to the pavement and steel that dominates the cityscape.
The environmental benefits of a green roof are many, and include the reduction of water runoff that occurs with typical homes. A reduction of runoff is good for the entire community, as too much runoff can result in flooding and water contamination. Because green roofs feature soil and plant life, these roofs are able to absorb as much as 75% of falling rainwater. This moisture is then released back into the air through condensation. A typical roof on the other hand is built to be totally waterproof, so every drop of water runs off and drains into the sewers.
Besides reducing water runoff, green roofs are also able to reduce the presence of toxins in the environment. Pollutants in the air and water, as well as carbon dioxide are absorbed by plant life and rendered harmless. These plants also produce oxygen.
Not only are green roofs great for the environment, but they are also an excellent investment. A properly installed green roof can last at least twice as long as typical roofing material, thereby saving you thousands of dollars in repair and replacement costs.
Green roofing can also significantly reduce your heating and cooling bills throughout the year. According to a recent study, building a green roof can reduce your heating and cooling needs by 26%. In cities especially, changes need to be made to the way that structures are built. Temperatures in cities are much higher than in surrounding areas because there is such a prevalence of buildings in a small area. These buildings are made with traditional materials, which absorb and then re-direct the sun’s heat. Cities are therefore much hotter than rural areas where there are less structures, and more green space. In order to combat the rising temperatures, some cities are offering incentives to builders to add green roofing to their projects.
If you decide to build a green roof, you need to keep a couple of things in mind. First, there are two types of green roofs. Traditional style roof gardens, which feature large plants or lawns, require a great deal of maintenance. Feeding, watering, and soil care are all necessary to keep this garden in good condition. Extensive roof gardens on the other hand, have only a thin layer of soil, and require very little work to maintain.
Great for the environment, good for your pocket book, and pleasing to the eye, green roofs are a budding trend that can have a positive impact on the environment. Not only that, but a well constructed green roof can increase the value of your home by thousands of dollars.
