Green roof refers to a system of roofing that uses plant life for roof covering instead of traditional covering materials. The system of green roofing dates back to the 1960’s but only in recentyears it has became a popular alternative to the traditional roofing due to its environmental benefits and savings for heating and cooling. The plants that cover the roof provide an excellent insulationto the building reducing business electricity and business gas consumption significantly but they also act as a natural filter for rainwater which means that they significantly reduce the amount ofrain drainage. The plants absorb over 50% of rainwater which would otherwise run into sewage system. The water that is absorbed by the plants on the rooftop then evaporates back into the air. But thebenefits of green roof technology do not end in reduction of rainwater.
Green roofing has become increasingly popular in cities because it creates additional green spaces that bring some nature in theconcrete and steel jungle. Green roofs in larger buildings often mimic parks and include rich vegetation that does not only provide an additional green space but also attracts wildlife includingbutterflies, honeybees and other insects as well as birds that can be otherwise rarely seen in urban areas. In addition, green roofs are visually appealing and create an attractive contrast to concrete andsteel, while many people take advantage of possibility to grow their own fruits and vegetables as well as flowers on rooftops. Some even have a nice set of teak garden furniture to get the best of thesunshine.
As already mentioned earlier, green roof is covered with plants, most often vegetation that is resistant to weather effects and requires little or no irrigation. Native, hardy, pest- anddisease-resistant, and fireproof plants that grow fast and are not invasive are ideal for green roofs. In addition to collecting rainwater, plants on rooftops also absorb the heat which keeps the...
