Green Roof Systems
Green roof is a kind of roofing system that utilizes plant life to cover a roof instead of traditional roofing materials. The use of green roofing systems originated in the 1960’s. However, it has only become a popular choice in recent years as an alternative to traditional roofing due to both its cooling and heating cost savings as well as environmental benefits. The plants covering the roof provide the building with superb insulation to significantly reduce energy consumption. In addition, they work as a natural rainwater filter, meaning they contribute to a significant reduction in rain drainage. More than 50% of rainwater is absorbed by the plants. This water would otherwise flow into the sewage system. The water that the plants on the roof absorb then evaporates into the air once more. However, there are even more benefits provided by green roof technology in addition to rainwater reduction in Denver.
Green roofing in Denver has become increasingly popular since it creates more green spaces which provide the steel and concrete jungle some nature. Green roofs on larger buildings frequently resemble parks. Rich vegetation is included, and in addition to offering added green space, it also attracts various wildlife, including honeybees, butterflies, insects and birds that otherwise are not often found in urban areas. Green roofs are also aesthetically pleasing and create an appealing contrast to all of the steel and concrete found in cities. Many individuals also take advantage of the opportunity of growing their own flowers, vegetables and fruits on rooftops. There are even some spaces that feature garden parasols and children’s garden furniture in order to enjoy the sunshine.
As mentioned previously, green roofs are covered with plants. It is most often vegetation that doesn’t require a lot of irrigation and is resistant to the effects of weather. Native, hardy, fireproof, disease- and pest-resistant plants that are not invasive and grow quickly are ideal to use on green roofs. Plants on rooftops not only collect rainwater but absorb the heat as well that keeps buildings warmer in the winter, and growing to medium size to help keep buildings cooler in the summer. It has been shown that green roofs reduce heating and cooling costs by up to 50 percent, which offers building owners major cost savings. Another significant advantage that green roofs offer compared to conventional roofing is that the plants absorb air pollutants such as carbon dioxide which leads to a reduction in heat island effects and lowers the temperature within urban area.
Green Roof Layers
There are always several other layers that make up green roofs in addition to plants, growing medium, drainage, insulation, filter cloth and waterproof membrane. How a green rooftop is constructed, in addition to which plants will be selected for the roof covering, will depend on a number of factors, which include type of roof and building size. Green roofing can be utilized with either a sloped or flat roof. However, creating park-like roofing systems is confined to larger building since accommodating trees and large plants is too heavy for medium-sized buildings and houses.
There are three major kinds of green roof plant selection, which are referred to as extensive, semi-intensive and intensive. Intensive green roofs are rooftops accommodating large plants which may include things such as full lawns and trees. A significant soil depth and maintenance is required for this kind of green roofing, which is similar to maintaining a large garden or park. Semi-intensive green roofs use moderate size plants requiring less maintenance for covering the roof. The most convenient green roof system type is an extensive green roof, which involves a roof covering comprised of a thin layer of vegetation and growing medium that require minimal maintenance and care.
When it comes to roofing systems, green roof technology is by far the most environmentally friendly. There is only one disadvantage. A green roof has much higher initial costs compared to traditional roofing due to having higher construction work costs. However, it is more cost-effective over the long term than even the least expensive roofing systems since significant costs savings for cooling and heating are offered by green roof technology. Some estimates show green roof lowering cooling and heating costs by more than 50%. Also, green roof systems have a tendency to be very durable. They can last up to 50 years and virtually no repairs are required compared to other kinds of roofing systems. When a green roof is combined with other types of green technology like solar photovoltaic panels and solar thermal collectors, it can reduce cooling and heating costs even further and help with combating global warming as well.
