Roof Color Energy Efficiency

This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof.

Roof color energy efficiency.

1 cool your roof cool roofs are lighter in color than traditional black asphalt or dark wood shingles and save energy by reflecting light and heat away rather than absorbing them. The color of the shingles you choose for your build can have a significant impact on the building s energy efficiency. Reformulate or coat black membranes to make them reflective. Built up roofs consist of a base sheet fabric reinforcement layers and usually a dark protective.

How they can be made cool. Single ply membranes are pre fabricated sheets rolled onto the roof and attached with mechanical fasteners adhered with chemical adhesives or held in place with ballast gravel stones or pavers. A darker energy star rated roof will usually outperform a lighter roof that isn t designed with efficiency in mind. While lighter colors are inherently more heat reflective roofing materials have a much larger impact on roofing energy efficiency than their colors do.

But the reality isn t quite as straightforward.
