Plano Roofing: Article About Extensive Green Roofing
Incorporating a green roof onto an urban residential property is an easy and effective way for homeowners to save money and beautify their environment. Some residential and structural factors come into play when looking at different options for using greenery on a roofing structure, but a certified Plano roofing professional can help property owners decide what type will work best for their home.
The most common type of living roof used on residential properties is an extensive green roof. An extensive roof uses a growing medium of less than 6 inches and typically includes plants that are easy to establish and maintain, such as succulents and herbs. Extensive roofs can be installed on either a flat or a sloped roofing surface, and once established, they require very little maintenance. There is no need to equip the roof with an irrigation system either.
Extensive roofs not only provide a habitat for urban wildlife, but they also help filter the air of pollutants so that it is healthier to breathe. An extensive roof absorbs rainwater, which alleviates some of the burden on the city's storm water runoff system, and it purifies the water as well.
Having a living roof can help mitigate the heat island effect, which causes an increase in the ambient temperature.

This translates as lower cooling costs for homeowners in the summertime. A living roof can also prolong the life of the roofing materials by absorbing sunlight, which is a major contributor to roofing damage, particularly asphalt shingles. In the winter, the added layer of insulation that the plants provide help hold the home's heat in, which also lowers heating costs. This insulating factor also attenuates sound, making the living environment more peaceful.
Living roofs installed on flat roof surfaces can also be used as a recreational area, providing an attractive and soothing area in which to relax. Some property owners elect to grow food on their roofing structures, but this does require a greater growing depth and may require some reinforcement of the roof decking.
Most rooftop gardens can be expected to last about 80 years or so, with little maintenance required. The longevity of the roof is largely determined by the climate and the type of plants used for the garden. Experienced roofers can advise property owners on the best types of plants to be used in their area so that they can enjoy a long-lasting and beautiful roof for many years.
