When remodeling a roof, homeowners often focus on the type of material, and the color becomes an afterthought. Not many people know that the hue of a roof can significantly impact a home’s energy efficiency. It’s vital to work with experienced professionals who can advise on how different colors might impact energy efficiency in Illinois’ climate.
Read on to learn more about the relationship between roof color and energy efficiency.
Roof Color and Solar Reflectance
Most people know that darker colors absorb more heat from sunlight than lighter colors and that wearing a black shirt on a hot day is a recipe for sweat. The impacts of roof color are no different, as darker shades absorb more of the sun’s heat, and some of it reaches the attic below. Conversely, lighter roofs reflect more sunlight away from the home.
The best color for a roof depends largely on regional considerations, as areas with predominantly warmer weather might favor the “cool roof” effect given by lighter tints. In a heating-dominated climate like Central Illinois, the U.S. Department of Energy notes that a light, reflective roof can carry a small winter heating penalty. Roofs get far more sun in summer than in winter, though, so for a well-insulated, ventilated attic, roof color has a modest effect on your total energy bill. Choose the color you like, and focus on insulation and ventilation. Darker shades can still make sense for Illinois homeowners:
- Darker roofs absorb more winter sun, which can slightly offset heating demand, although insulation and air sealing matter far more.
- The dark color melts snow faster and may help prevent snow stains and ice dams (with proper insulation beneath it).
- The home below benefits from better heat retention and is more comfortable.
In warmer parts of the state, lighter-colored roofs can be an effective way to decrease cooling costs.
The material of the roof is also important, as certain options offer better solar reflectivity than others. Metal roofs, for instance, better reflect sunlight away from the home than even the lightest colored shingles.
Many homes in Illinois use asphalt shingles because they are affordable and come in a range of colors.
What Else Affects the Energy Efficiency of Your Roof?
While roofing colors and materials are important, they’re not the whole picture when it comes to energy efficiency. Homeowners must also consider their home’s structure and insulation. The insulation of the attic and upper floors is especially important, as this effectively transfers the heat from the roof to the rest of the home.
Poorly insulated attics are disadvantageous in both the warm and cool months. In the summer, they allow excess heat to seep into the structure below; in the winter, they fail to trap the heat from the roof long enough to radiate into the home. Proper ventilation is also key to optimizing heat exchange from the roof without moisture buildup in the attic, which may lead to mold and mildew issues.
The Best Roofing Options for Sustainability
Ecologically minded homeowners in Illinois should work with a professional roofing company to choose the colors and materials that best support energy efficiency. Usually, dark roofs made of asphalt or fiber-cement shingles work best. Metal roofs in darker shades can also be an option, but the installation cost is typically higher.
