Folsom Roofing: Article About Green Asphalt Roofs
The vast majority of American homeowners use asphalt shingles to cover their roofs. Asphalt shingles are inexpensive, come in a myriad of styles and colors, and they can easily be installed by a Folsom roofing contractor. However, these shingles have had the reputation of being environmentally unfriendly. They are made from petroleum, a non renewable resource. Asphalt shingles contribute a significant amount of waste to landfills. Fortunately, there are ways to make asphalt shingle roofs greener.
Compared to other roofing materials, asphalt shingles have a short lifespan that typically ranges from 15 to 30 years. However, longer lifespan asphalt shingles that last 40 to 50 years are commercially available. A homeowner who purchases these long lasting shingles will need to replace their roof less often and reduce the amount of waste sent to the landfill.
Homeowners can make their asphalt roofs more eco friendly by installing cooler roofs. In contrast to dark roofs, which absorb sunlight, light colored roofs reflect the sun's rays. Light colored shingles result in a cooler roof and therefore a cooler house that uses less energy on air conditioning. Studies have shown that white roofs decrease air conditioning costs by at least 20 percent in hot weather.

A homeowner does not have to commit to a white roof in order to keep his house cool. Solar reflective shingles that come in shades of gray and brown are also available. Solar reflective asphalt shingles can even simulate the look of weathered wood. These shingles can have as much as 40 percent solar reflectivity, which is the highest reflectivity for asphalt shingles. No matter the roof color, a cool roof has a higher life expectancy because it experiences less contraction and expansion than a standard roof.
Another way to go green with asphalt roofing is by recycling old shingles. Discarded shingles still have value because they contain asphalt that can be used for road construction and maintenance. The average asphalt roof has enough shingles to pave 200 feet of a highway. Other uses for recycled asphalt shingles include the manufacture of roofing products and energy production. Even the nails on asphalt shingles can be recycled. The nails are automatically pulled from shingles by powerful magnets during the recycling process.
Asphalt shingle recycling reduces the amount of waste in landfills. In addition, road construction and maintenance companies would reduce their need to purchase new asphalt, which is made from non renewable petroleum. Asphalt shingle recycling also creates jobs in the recycling industry. Furthermore, shingle recycling saves taxpayers money on road maintenance since recycled asphalt costs less than fresh asphalt.
