Most people never think about roof color, but Berkeley Lab found swapping a dark roof for a reflective "cool roof" cuts a building's annual air-conditioning energy use by 5–20%

Studies show these roofs cut air conditioning costs by ten to fifty percent. This simple change also lowers outdoor air temperatures in neighborhoods. Choosing cool roof products offers substantial savings and environmental…
