Asphalt shingles are the most commonly used roofing system in the country. These shingles are made of a fiberglass base that is then coated in ceramic granules, which make them hard and give them color. Asphalt shingle roofs are very durable, and they can withstand a great deal of severe weather. However, they may come loose in high winds. Asphalt shingle roofs can last anywhere from 20 to 30 years, and they cost between $2.50 and $8.00 per square foot.
There are many colors and types of asphalt shingles, and some of them have been manufactured so that they are energy-efficient. Dark-colored asphalt absorbs the sun’s rays, making it very hot. According to National Geographic, it takes 40 percent more energy to cool a home with a black asphalt roof. Fortunately, new, lighter asphalt roofs are now available, and they are ENERGY STAR-qualified. Homeowners with ENERGY STAR-approved roofs may qualify for federal tax credits. In addition, a special reflective coating that’s made from polymers can reduce energy costs even more. According to the Green Building Alliance, this coating for asphalt shingles can reflect 70 to 80 percent of the sun’s heat.
