Urbana Roofers: Article About Cool Roofs
Increasing energy costs are leading many homeowners to consider energy efficient materials for their next roofs. In keeping with this trend, the roofing industry has developed a variety of energy saving roofs, with cool roof products leading the way.
In choosing the right cool roof, most homeowners are smart to rely on the advice of experienced Urbana roofers who understand the types of roofs that work best for the region. Even so, consumers who know a little about cool roofs can participate more knowledgeably in the decision making process.
As ingenious as cool roofs are, they really just expand on the fact that items covered in light colors stay cooler than those covered in dark colors. Traditional shingle roofs tend to be dark, absorbing the sun's intense summer warmth and transferring that heat into the structure below. Considering that dark roofs can become as hot as 150 degrees Fahrenheit, the heat transfer into homes can be significant. This escalating interior heat leads homeowners to run their air conditioning systems for lengthy periods in order to reach a comfortable temperature.
Those traditional hot roofs actually heat the air around them too.

In large cities, this accumulation of extremely hot roofs leads to the Heat Island Effect, increasing the city's temperature 1.8 to 5.4 degrees compared to other nearby towns.
Cool roofs change all that. Early cool roofs were light colored, but today's cool roofs are coated with a light reflecting pigment or paint that keeps the roof up to 50 degrees cooler than a regular dark roof. This cooling allows homeowners to save 10 to 30 percent on their typical air conditioning costs.
Savings on utility bills aren't the only advantages to cool roofs, however. Excessive heat can break down roof coverings like asphalt shingles, shortening their lifespan. Because cool roofs avoid that heat buildup, they age more slowly and are more durable.
Homeowners have plenty of cool roof options, including high end architectural shingles, affordable asphalt shingles, metal roofs and concrete tiles. The color range of these roofing materials has opened up as well. "Cool dark color" roofs allow homeowners to choose a more traditional looking roof while enjoying all of the benefits of cool roofs. There's even research underway to create a coating that will reflect heat in the summer and absorb solar heat in the winter to maximize a home's energy efficiency. For more information about a specific roof's cool ratings, homeowners can take a look at the roof's Solar Reflectance Index listed on each roof's manufacturer label.
