Roof Shingle Colors Energy Efficiency

This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof.

Roof shingle colors energy efficiency.

This can lower roof surface temperature by up to 50f decreasing the amount of heat transferred into a building. The industry has long held the assumption that white roofing because of how it reacts with surrounding air temperatures think about the idea that the color white. Energy star certified roof products can help reduce the amount of air conditioning needed in buildings and can reduce peak cooling demand by 10 15 percent. Coating existing asphalt shingles to make them cool however is not normally recommended or approved by shingle manufacturers.

How they can be made cool. Modern energy efficient metal roofing acts as a giant mirror of sorts by reflecting the heat and energy up into the air. White roofing isn t always green. The color of a roof also plays a part in whether the roofing is energy efficient.

Energy star certified roof products reflect more of the sun s rays. A white or light colored metal surface reflects best under testing at about 67 percent reflectivity and even some newly developed cool colors send the rays away source. Florida solar energy center. Lighter roof colors will reflect more of the sun s energy while darker colors tend to absorb heat which can then transfer to attics where it can seep down into the home.

Calculate your energy savings from a cool roof. Buy cool asphalt shingles which use specially coated granules that provide better solar reflectance. And while asphalt tiles don t have the power of a magnifying glass they do intensify the heat from the sun by holding it long after the sun itself has called it a day. Energy saving shingles include products made from a variety of materials available in many colors.

In general dark colors tend to absorb more heat and on roofs that heat is transferred to the building. Shingle roofs consist of overlapping panels made from a variety of materials such as fiberglass asphalt wood polymers or metals. The color shingles your clients choose can have significant effect on the temperature of the upper levels of the building. Studies by the heat island group and the florida solar energy center have shown that.

These options allow you to choose a color that makes sense with a home s style while increasing its energy efficiency. Cool roofs are lighter in color than traditional black asphalt or dark wood shingles and save energy by reflecting light and heat away rather than absorbing them. While it s true that lighter colors generally reflect more light than darker colors cool roof shingles actually come in a variety of colors.
