When it’s time to reshingle your roof, consider ENERGY STAR® rated cool roof shingles.

Asphalt shingles that use cool roof technology can cut your summertime cooling expenses by 7% – 15%.

Energy Star Cool Roof Shingles The key to a cool roof, says the Cool Roof Rating Council,  is to reflect this energy before it can be turned into heat.

While it’s great to think about saving up to 15% on your summer cooling costs, you might wonder if you’d be giving up potential solar heating attributes in the winter.

No worries – research has shown that the benefits of cutting summer cooling requirements far outweigh the benefits of any solar gain through the roof in winter. Additionally, winter has much shorter daylight hours and the weather tends to be more overcast over the winter months.

Besides giving architects and construction managers a wider palette of attractive colors to use in their building designs, the cool roof movement can add up to significant savings. ~Randy Woods, @EarthTechling


These energy-efficient shingles are installed just like standard shingles, and it’s a do-able job for an experienced DIYer (as long as the roof isn’t steep – 6/12 pitch or less). We give this project a “DIY Hero” difficulty rating.
