Shingle colors can have a significant impact on a roof s energy efficiency.

Roof shingle color energy savings.

As such your roof plays the biggest role in determining how much of the sun s heating gets into your home. Darker colors absorb heat. Emissivity and how it relates to energy savings and cool roofs. The color of the shingles you choose for your build can have a significant impact on the building s energy efficiency.

The greatest savings resulted from using white metal roofing see table 2 18 shown at left. Energy star certified roof products. Attic temperatures can vary as much as 20 to 40 degrees f which in turn can reduce energy consumption by 20. Cool roofs can save money several ways including energy savings rebates and incentives hvac equipment downsizing and extended roof lifetime.

Additional cool roof costs include specialized materials and labor. This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof. Brighter or lighter colors tend to reflect away not just light rays but. The color shingles your clients choose can have significant effect on the temperature of the upper levels of the building.

The industry has long held the assumption that white roofing because of how it reacts with surrounding air temperatures think about the idea that the color white reflects color rays while black.
