Shingles come in many colors, but dark ones are especially popular, says Jesseca Kusher. The 18-year old attends Spartanburg Day School in South Carolina. Like most dark objects, shingles absorb a lot of heat from sunlight. In the summer sun, they can easily reach 73.5° Celsius (164° Fahrenheit), she notes. If those shingles reflected more sunlight, they’d stay cooler. And that could help cut down on home cooling bills. According to the Environmental Protection Agency, air conditioning consumes about 5 percent of all the energy used in the United States. Cooling buildings costs the nation about $11 billion each year.
