Have you ever heard about color choices having an effect on your roof’s efficiency? Many people still have doubts about whether choosing different colors will make a significant difference. As a full service roofing company, we did our research and found four examples which support the claim that lighter colors make for cooler roofs.
1. The Difference Matters Enough
A research study done by the United States Department of Agriculture wanted to see how much color can have an effect on the amount of heat absorbed by a roofing material by checking the temperature of wood panels placed under black and white shingles. During the test, the panels that were under the black shingles were up to 15 degrees warmer than those placed underneath the white shingled roofs.
2. Lighter Roof Colors Reflect More Heat
We now know that color choice matters, but how exactly does it work? When light reaches the surface of an light-colored object, a huge portion of the light and heat energy is reflected away. On the other hand, dark-colored surfaces absorb more light and heat energy, which is then transmitted to the other side of the roof. This is why a roofing contractor will be more likely to recommend light-colored options to clients.
3. Red Isn’t So Hot
You probably think that not using red roofing will make your roof cooler, but the opposite is actually true. Although red has been associated with hot things, a study shows that a red-colored object feels cooler than a blue object when exposed to similar light conditions with a difference of about 30 degrees.
4. Shinier Is Better
Since color helps in reflecting more sunlight, this should clue you in on another roof-cooling option. Glossy finishes can help reflect even more light off the roof surface so before you ask “are there any roofers near me“, you should already have decided on a shiny, light-colored roof.
