Many people may be wondering "what is a green roof?" Basically green roofs which have also been referred to as “eco-roofs” are rooftop gardens or parks or meadows. These roofs carry a host of environmental and economic benefits. By using soil and plants on rooftops instead of hard, impenetrable roofing materials city governments, developers and/or individual homeowners can reduce air pollution, reduce rain water runoff, add insulation to a building, help reduce global warming by capturing carbon dioxide, create new habitat for birds and double or even triple the life of a roof. Many cities are offering incentives to encourage homeowners, developers and local businesses to install green roofs on new and existing buildings.
The U.S. Environmental Protection Agency also known as the EPA encourages the creation of green roofs for solving the urban "heat island effect" whereby temperatures in crowded cities can soar some 10 degrees Fahrenheit higher than in less developed areas nearby. The green roof works by the cool roof reflecting and emitting the sun’s heat and rays back to the sky.
When it comes to outlasting traditional roofs, green roofs surpass them in lifespan. Metal roofs which are known to be relatively maintenance free and last longer than shingles don't even compare. Slate roofs also have an excellent reputation for lasting long, although getting work done on them can be expensive when they do need repairs. The Slate Roofing Contractors Association states that sea green slates can last anywhere from one to two centuries, depending on where the slate is obtained and how well it is installed.
I find that there are many benefits to a green roof. The idea of it is very simple and it does save you money in the long run also by not having to spend as much to maintain a roof. The green roof also provides many benefits, and people who have it would probably never even realize that. To me a green roof should definitely be considered by all.
