Are you considering a new roof for your home?
So-called green roofs are probably your best bet, not only are they good for the environment, but they are also your wallets best friend.
While they have been used in the United Kingdom and other parts of Europe for decades, green roofs have only recently started to sky-rocket in the United States. In the last five years, the number of green roofs grew by as much as 110 percent, according to the study performed by the Green Roofs for Healthy Cities.
So what exactly is a green roof?
A green roof is defined as a light weight, living self-sustaining system of soil, plants, and compost. They are usually comprised of as many as nine layers, including structure support, vapor barrier, waterproofing, drainage, thermal insulation, growing medium, a filter membrane and last but not least, the plants.
A green roof is amazing to the environment due to its ability to absorb water instead of allowing it to drain off to the pavement. As that water evaporates, it cools the roof, lowering the temperature. This is particularly useful in urban climates, with dry, hot air.
Green roofs also improve insulation, most of the heat is lost trough the roof and having nine layers of insulation helps reduce that to a minimum. Green roofs also help during summer, being green they remain cooler than black roofs which absorb much more of the sun’s energy.
The price of green roofs usually starts from $15 per square foot but can go higher, depending on many factors, such as size, depth, growing medium and the vegetation itself. Taken that into account green roofing can still come out much cheaper than other traditional types of roofing. The need for a low-impact stormwater management is currently the biggest driving force behind green roofs in the United States, helping reduce the possibility of roof leaks and helping stop the damage rain can cause.
Depending on the type of the roof, the depth can reach from as little as few inches all the way to a foot.
Vegetation used can range from small bushy plants to native grassland plants, shrubs, bushes, and even trees in extreme cases. Crops like vegetables are also a possibility, while they do require a little bit more care they are an amazing way to utilize your roof and get even more bang for your buck.
Integrating solar roofing along with your green roof can provide even more of a green boost to your home. Not only saving you money but providing you with an alternative source of energy and helping you save the environment.
Green roofing is becoming more and more popular; even Facebook is using green roofs at their headquarters, and many NYC schools have turned to green roofing and solar power to help combat the air pollution and show it’s students the right way forward when it comes to climate change and renewable energy.
