Until fairly recently, asphalt shingles were simply not featured on the list of possible roofing options for environmentally conscious homeowners. Asphalt shingles ended up in landfills after their useful life was over, and their potentially toxic materials caused all kinds of problems. Environmentally conscious homeowners usually selected an expensive, natural wood shake roof instead that required heavy maintenance.

However, in today's world, old asphalt shingles are no longer simply dumped in landfills to create a toxic mess. Responsible Raleigh roofing professionals take them to recycling facilities. Being made primarily from asphalt and stone granules, these shingles can easily be turned into roads. Asphalt shingle recycling is an economically viable process that produces high quality paving materials.

Asphalt shingles have also been developed into what are called "cool roof" surfaces. In hot countries, people realized eons ago that putting a white roof on the building kept it much cooler. Being made out of black asphalt, asphalt shingles have always tended to be dark in color and tend to absorb, rather than reflect, the heat of the sun. Even pale colored asphalt shingles tend to absorb heat due to the internal characteristics of the asphalt.

However, advances in technology have allowed for the development of reflective "cool roof" asphalt shingles. Cool roof shingles are rated on their ability to reflect the sun's rays and on their ability to radiate away absorbed heat.

The roofers at Otto's Exteriors of Raleigh NC can assist you with any questions regarding gutters or shingle roofing.

These two characteristics are given a rating of 0 to 1 where 1 is an ideal cool roof surface. White roofs will always be cooler than any colored roof due to the ability of white to reflect both visible and infrared light. However, a number of pigments have been developed that look colored to the naked eye yet are capable of reflecting most of the infrared light from the sun. It is not necessary to sacrifice aesthetics in the quest for a cool roof.

Cool roofs make a dramatic difference in energy consumption, especially in warmer climates. The installation of a cool roof can significantly cut into air conditioning needs and costs. In some areas, homeowners can get a rebate on their utility bills if they install a cool roof. Another advantage of installing cool roof asphalt shingles is that the sun reflective technology can extend the lifespan of the shingles. Heat and damage from the sun's rays are a major cause of asphalt shingle breakdown. If the shingle's special reflective surface prevents the sun's rays from penetrating the shingle, it will last longer. Environmentally conscious homeowners can relax knowing that their choice of asphalt shingles was a very green one indeed.
