Why Metal Roofing V Composition Roofing


If green is the new black, then in the world of roofing, metal is the new wood shake shingle. Often times, people are surprised to learn that different types of metal roofing exist, let alone that they’ve been available for over 50 years. Such is the case with Gerard’s stone-coated metal roofing technology, available from True Green Roofing Solutions.

At 1.5 pounds per square foot, stone-coated metal roofing is viable for new construction as well as old shakes and decaying composition (systems can actually be installed directly over old roofs, effectively adding extra insulation and eliminating landfill waste). These versatile roofing systems install quickly and easily over a 2×2 wood batten system. They also help reduce energy costs, as the stone-coated steel systems allow for continuous airflow across the deck, which means less heated air in the attic. This results in less stress on the cooling system and lower energy consumption. In areas such as ours that experience all four seasons, these systems add an average insulating factor of R11 to a house, creating a more efficiently cooled or heated home.

The Gerard metal roofing systems are the only stone-coated steel systems proven to withstand the climate extremes and snow loads found in the Reno, Nevada,Truckee/Tahoe Donner and Lake Tahoe areas. They are class A-rated for fire, come with a lifetime warranty and are authorized for use by the respective building departments throughout the area. Whether this is your home or your home away from home, you owe it to yourself to look at your options.

The EPA reports that $40 billion is spent annually in the United States to cool buildings. This accounts for one-sixth of all electricity generated in a year. These staggering statistics, coupled with the rising cost of heating and cooling homes, have homeowners looking for ways to save the earth and save money on energy costs.

Green building practices promote construction of buildings that are healthier for the occupants and healthier for the environment. The metal roofing industry’s products are already environmentally friendly as most metal roofs contain more than 25 percent recycled content. This level of recycled content allows metal roofing to be included on listings of ‘green’ and recycled content products. In addition, metal roofing is 100 percent recyclable. Traditional roofing products, such as asphalt, contribute 13 billion pounds of waste to U.S. landfills annually. Many metal roofs can be installed over an existing roof, without tear-off and disposal.

A cool roof is often described as one that has a high solar reflectance and a high thermal emittance. The emittance of a material refers to its ability to release absorbed heat. A roof is ‘cool’ if its surface temperature is lower, and as a result, the cooling load in the building is reduced. Solar reflectance is the most important characteristic of a roof product in terms of yielding the highest energy savings during warmer months. The higher the solar reflective value the more efficient the product is in reflecting sunlight and heat away from the building and reducing roof temperature.
