Lower Energy Costs With an Eco-Friendly, Stylish Metal Roof

Homebuilders and homeowners considering roofing options should take a look at metals roofs, a fast-growing home and green improvement trend. Metal roofing has evolved into an environmentally conscious industry that features high-quality, lightweight, long-lasting and recyclable materials that can be fashioned to mimic almost any roofing style. Think of it as a material upgrade on asphalt, clay, wood, and other traditional (and less durable) materials.

Tax Breaks and Energy Savings

Certain roofing materials are Energy Star® rated by the Environmental Protection Agency or EPA for reducing energy costs. Roofs installed in 2012 or 2013 are eligible for tax credits up to $500 through December 31, 2013. This only applies to principal residences.

Metal roofs qualify for Energy Star ratings and can lower roof temperatures by up to 100° and reduce peak cooling demand by 15%, according to EnergyStar.gov. They also provide better insulation against heat and cooling losses. Researchers from the Oak Ridge National Laboratory found that these roofs lower heat loss in winter by nine percent, and reduce heat gain in summer by 37.6% compared to asphalt roofs.

How does this work? Metal roofing products reflect-rather than absorb-sunlight, which means the house below stays cooler. The insulation installed under them conserves heat in winter and colder climates. They also melt snow and ice more quickly, removing the threat of ice buildup, icicles, or ice damming that can occur when snow backs up against eaves.

Style and Durability

Metal roofs don't have to look like they're well, metal. Manufacturers have created styles and coatings to mimic the look of traditional roofing materials. As for durability, few homeowners ever need to replace one of these roofs on their own dime. The Metal Roofing Alliance, an organization of roof manufacturers, paint companies, distributors, and contractors, says most of these roofs are expected to last 30 to 50 years and come with warranties to cover these periods. Asphalt roofs typically need replacement every 25 years or so.

Because these roofs deteriorate much more slowly than competing products, insurance companies in several states offer discounts up to 30% for homes sporting them. In addition, these roofs are non-combustible and have a Class A fire rating, the highest possible. Wood and shingles are rated at the lower Class C. In addition, these eco-friendly roofs are 100% recyclable, and recycled materials contribute to about 25% of the manufacturing process.

Myths About Metal Roofing

Here are some answers to common misperceptions about these high quality roofs:

1. Lightening risk. Metal conducts electricity but is not drawn to it. Since they are non-combustible, they are safer as well.
2. Noise factor in rain. Properly installed metal roofs are placed over attics and insulation and are as quiet as other roofs.
3. Hail damage. Normal-size hail will not damage a them. In addition, texturing makes dents less visible if they do occur.
4. No walking allowed. There are ways to walk on these roofs without damaging them. Check with the manufacturer.
5. Poor resale value. Not so, says Yahoo!Homes, which mentions metal shingles that look like slate as an affordable and attractive remodeling investment option. In fact, in snowy parts of the country, a metal roof is likely to attract potential buyers and even may be a factor in the seller getting a higher price.
