RISMEDIA, April 20, 2011-Searching for ideas to make your home greener, with a smaller eco-impact? Now may be the best time to look up, as the roof over your head can make a big difference to the environment. While most people never think about their roof until there is a problem, planning ahead is key for making eco-friendly home choices.
The experts at the Metal Roofing Alliance provide the following information regarding eco-friendly roofing materials.
Did you know that asphalt shingles are petroleum-based, with a huge environmental impact? Asphalt shingles increase dependency on fossil fuels, must be replaced every 15-20 years, and there's no good way to dispose of them.
Eco-friendly products, including metal roofs, are rapidly replacing petroleum-based shingles. A recent McGraw-Hill Construction and Analytics survey showed metal roofing now comprises 11% of the residential re-roofing market, more than doubling in just ten years.
Highly reflective 'cool' colored metal roofs look just like traditional roofs, provide year-round relief from high energy costs, and are sustainable products.
Installing a metal roof reduces a home's energy needs. Tests conducted by Oak Ridge National Laboratories (ORNL) prove that a cool metal roof can save a homeowner up to 25% in cooling costs compared to a dark-gray asphalt shingle.
ORNL's field tests have also shown the combination of venting and increased reflectance can reduce heat penetrating the roof deck by about 45% for stone-coated metal roofs compared to an asphalt shingle roof in certain climates. Ongoing research with standing-seam cool-colored metal roofs is showing similar results.
Metal roofing provides a market for recycled materials. An old car, dishwasher or refrigerator can be recycled to re-roof a home. All steel roofs contain a minimum of 25% recycled content-many have a much higher percentage. At the end of its useful life, metal roofing is 100% recyclable.
Photovoltaic Systems and Solar Panels can be integrated into metal roof systems, making them an even better choice. Metal roofs can also allow consumers to harvest rainwater for reuse.
