Metal roofs are energy efficient and consist of many recyclable materials.
Asphalt shingled roofs have traditionally been the most popular, but according to recent claims, metal roofing is making a significant marketing growth over asphalt. Although asphalt does offer good protection and a variety of shapes, styles, and colors, it does not seem to last as long as other types of roofing, especially metal. With more and more awareness of environmental issues and green code planning making waves in homebuilding, consumers are turning to more eco-friendly products, thus replacing petroleum based asphalt shingles.
Survey Shows Homeowners Choose Metal
According to PR Newswire-US Newswire, when homeowners were asked why they chose metal roofing over asphalt, 61% reported it was for metal's longevity, while 16% sited strength and protection. Other homeowners say metal roofing is a good investment that adds value and is environmentally friendly.

Advantages and Characteristics of Metal
Metal roofs also have the advantage to mimic other roofing types, such as wood shakes, clay tiles, and shingles. Metal is durable, fire retardant, and requires little maintenance. Metal roofs are energy efficient and consist of many recyclable materials, adding to their desirability for green building. They are lightweight and can be installed over an existing roof. Most metal roofs weigh from 80 to 145 pounds per square; aluminum roofs weigh 40 to 70 pounds. Compare this to asphalt, weighing from 234 to 425 pounds.
It is true that asphalt is very durable and usually has Class A fire protection, but it doesn't perform well in high winds, blowing off under heavy wind conditions. The shingles scar easily in hot weather. This damages their appearance and breaks down durability. Shingles require some maintenance every couple of years.
The biggest drawbacks for metal roofing are more difficult installation and higher costs. However, metal roofs are resistant to rust, algae, decay, and discoloration. Given this lifelong durability and low maintenance, the cost may be worth it.
Making the Choice
The choice of roofing types is still up to the homeowner, but clearly metal is gaining more popularity over asphalt shingles as homeowners become more and more conscience of their energy efficiency and the environment. Be sure to consider other types of roofing materials before you replace your roof, and call a professional to help make the best choices for you!
