At a time when more companies than ever are going green, the environmental design industry is expanding rapidly. Today, companies embrace practices that benefit their finances and the environment simultaneously, such as eco friendly roofing. If you have heard of green roofs (a.k.a. natural and eco friendly roofs), but are unacquainted with their construction and benefits, the answers below can help.
How are green rooftops constructed? Natural roofs are constructed of the following elements: a high quality waterproofing membrane, a roof deck, a drainage and irrigation system, soil areas, and shallow growing plant life. These elements combine to form a rooftop that offers numerous environmental and financial benefits.
Are green rooftops different than rooftop gardens? Natural rooftops are superior due to their design. A rooftop garden is essentially a garden on a rooftop, which brings the following disadvantages: the need for increased structural support, lack of proper waterproofing, lack of proper decking, lack of proper drainage and constant maintenance. Conversely, green roofs are designed to eliminate these problems, and feature a high degree of self-sustenance.
Is it possible to grow trees on a roof? Trees with shallow root systems may be acceptable on certain rooftops, but larger trees would require too much soil.
Do eco friendly roofs improve energy efficiency? Natural rooftops can improve energy efficiency in the following ways: by deterring heat escape in the winter, deterring heat intrusion in the summer and increasing HVAC efficiency. Research by the National Research Council of Canada (NRC) shows that natural roofing can reduce the demand for summertime air conditioning by up to 75%.
How do green rooftops benefit the environment? Natural roofing benefits the environment in critical ways. For one, it improves air quality by capturing airborne pollutants and atmospheric deposits. For another, it improves the cleanliness of storm water runoff by up to 85%. It also improves roof longevity, decreasing landfill use.
Do natural rooftops last longer than standard ones? A natural roof can improve upon the life cycle of a standard one-meaning one that could deteriorate within two decades-by up to 100%. Although it costs more initially, an eco friendly rooftop is the most affordable option in the long run, both in terms of repair and replacement.
How much does a natural rooftop cost to implement? Cost of implementation is based on the following factors, among others: a roof’s square footage, how easy it is to access, the types of plants chosen and the cost of construction supplies. To find out how much green roofing would cost for your building, contact a roofing company that specializes in eco friendly designs.
Can an eco friendly rooftop be placed on a pitched roof? Technically, an eco friendly rooftop can be placed on almost any style of roof, including one that is pitched. However, pitched roofs only accommodate shallow growing grasses, vines, and flowers, and may not feature the same design benefits as their flat counterparts, which are the type of eco friendly roofs that most commercial roofing contractors in the U.S. specialize in.
