Metal Roofing Materials

Building a green home requires attention to every product and material that goes into constructing it, and nowhere is that more important than choosing the right roofing material. The roof of a home has to be able to stand up to harsh conditions all day and all night; the sun's damaging UV rays, rain, wind, snow, and extreme heat and cold; the roof of a green home has to do this as well as have a minimal impact on the earth's resources.

Traditional asphalt shingles are by far the most common type of roofing material for new and replacement roofs, but they are far from being the most earth-friendly. They are made with toxic adhesives and non-renewable fossil fuels, typically last only around 15 to 20 years, and are very hard to recycle at the end of their life span. All of this requires a great deal of energy to produce new shingles, and a great deal of landfill space when their time is up.

According to the National Association of Homebuilders Research Center, 20 billion pounds of asphalt shingles are sent to U.S. landfills each year. If you put all those shingles into tractor trailers and lined them up end to end, the line would stretch from New York to Los Angeles, back to New York, then back to Chicago. Needless to say, that's a tremendous amount of waste.

Further Considerations for Metal Roofing Materials

Cost: Metal roofing is considered a premium roofing material, and as such carries a higher up-front price tag than a traditional asphalt roof. Metal roofs are, however, typically less expensive than cedar shake or tile roofing. The thing to remember is, even though the cost is higher up front, the savings over the long term are substantial; a metal roof will last 30,40,50, even 60 or more years, will help to reduce energy bills, and will add resale value to your home.

Noise: Many people think that a metal roof is going to be noisy in rain or other bad weather. In a residential structure, metal roofing is typically installed over a solid substrate with attic space and insulation between the roof and the living areas. Metal roofing is not going to be any noisier than another type of roof.

Lightning!: 'Will my house be struck by lightning more with a metal roof?' is a common question asked about metal roofs. While a home covered with a roof of metal might seem like a giant lightning magnet, in reality this is not the case. Lightning is attracted to the highest point of a structure regardless of what it's made of. A metal roof is not any more likely to be hit by lightning than any other kind of roof. In fact, in the event of a lightning strike, a metal roof can help prevent a house fire by dissipating the electrical charge over a large area. Metal is also completely noncombustible. Whew!
