Dark Roofs vs. Light-Colored Roofs

Posted on December 28, 2017 · Posted in Roofing Education

When installing a new roof or replacing an old one, you may be considering whether to choose a dark colored roof or light-colored roof. A 2015 article in Engineering Green Buildings  stated that an increase in the popularity of light colored roofs in southern U.S. states seems to be making its way north. While the lifespan of each shingle color is basically the same, there are some very important differences you should be aware of, especially when it comes to the energy-efficiency of your Maine home. There is a lot more to your roof than whether the color is pleasing to the eye.  

White roofs earned their newfound acclaim in warmer climates due to their ability to reflect 75% of the heat from the sun, helping cool homes and reducing energy consumption and peak cooling demand. However, in an article from Waterproof Magazine, this high rate of reflectivity from white roofing can be a strain on the eyes, especially for those living in adjacent buildings and homes. And while it may reduce the cost of air conditioning in the summer, northern homes may experience heating penalties in the winter.

For northern states that experience cooler summers and much colder winters, a black roof may absorb and hold the solar energy, helping to retain heat in the home and reduce energy consumption.. For regions that experience snowfall throughout the winter months, the heat from a black roof may help melt the snow on the roof and prevent ice damming.

While both black and white roofs provide their own advantages and disadvantages, it can be difficult to know which one will work best for you.
