White Roofs Catch As Energy Cost Cutters
Relying on the centuries-old principle that white objects absorb less heat than dark ones, homeowners with white roofing are in the vanguard of movement embracing “cool roofs” as one of the most affordable weapons against climate change.
Studies show that white roofs reduce air-conditioning costs by 20 percent or more in hot, sunny weather. Lower energy consumption also means fewer of the carbon dioxide emissions that contribute to global warming.
What is more, a white roof can cost as little as 15 percent more than its dark counterpart, depending on the materials used, while slashing electricity bills.
