Is a lighter or darker roof better?
Energy Efficiency
As mentioned earlier, light-colored roofs are known for energy-saving capabilities. Your roof significantly impacts the temperature inside the building, and a dark roof is more likely to conduct a warmer temperature on the structure below, increasing cooling efforts such as air conditioning.
Which color is best for roof?
Grey or Multi-Colored
Grey roofs minimize heat absorption on hot days, keeping the house relatively cool while maximizing heat on colder days. Similarly, multi-colored roof tiles that include black and white specks also help cut down on heating and cooling costs, as the black absorbs heat, and the white reflects heat.

Dark Roof Shingles vs.
Darker colors absorb more heat, and warmer roofs make it easy for snow and ice to slide right off. Lighter colors reflect sun rays, keeping roofs cooler and helping homeowners in warmer climates save a little on their energy bills.
Does a lighter roof make a difference?
White roofing products stay coolest in the sun, reflecting about 60 – 90% of sunlight. However, since about half of sunlight arrives as invisible “near infrared” radiation, we can boost the solar reflectance of dark materials by using special pigments (colorants) that preferentially reflect this invisible light.
What color roof keeps a house the coolest?
