Green Roofing Products: Upgrading to a Cool Roof
May 15th, 2012
Green. A good color, a great concept, but what does it mean for roofing products if your roof is pitched? Is “Going green” installing a lawn on your roof? Could be, but consider this: Many roofing product manufacturers have created and designed shingles to keep with current trends.
The sun is a magnificent heat source, though brutal to a home’s structure. When designing shingles, manufacturers found creative ways to distribute heat effectively and evenly. White is a natural reflective color, and has been a standard color for this purpose. Recently, shingle desigers have come up with colors that are pleasing to look at and enhance curb appeal.
CertainTeed produces a shingle called Landmark Solaris. This shingle is made to reflect 40% of the sun’s solar rays and evenly distribute heat better than a standard composition shingle. The shingle is Energy Star qualified that meets both “solar reflectance and thermal emissivity requirements,” (CertainTeed website, Landmark Solaris).
GAF has a shingle line out called Timberline Cool Roof shingles. Colors available are: Cool Antique Slate, Cool Barkwood and Cool Weathered Wood. This shingle can save homeowners up to 15% of their total cooling costs in the summer months. This diagram (taken from the GAF website) compares conventional roofs to cool roofs, noting a 10 degree difference in the attic space and a 21 degree difference on roof top heat, thus creating an overall savings in cooling the home.
Be informed. Surf the internet to see what is available and talk to the professionals who install these products. Ask for referrals of customers who have installed the products to see if the claims hold true.
