Which Roof Color Has the Highest Energy Efficiency?

Which Roof Color Has the Highest Energy Efficiency? – Four Seasons Roofing – Seattle, Snohomish, Everett, Bellevue
Discover how roof color impacts energy efficiency.

Let’s start by defining energy-efficiency as using as little heating and cooling as possible to keep your home at a comfortable temperature. In general, a light-colored roofing material will reflect more solar heat and keep your home cooler, whereas a dark-colored roofing material will absorb the sun’s energy and keep your home warmer.

How Much of a Difference in Temperature Does Roof Color Make?

The difference in temperature between the most and least heat-effective colors can be as much as 20 degrees depending on the various specified criteria. Insulation and ventilation are key to how much of the heat actually enters your home.

Think about whether heating or cooling is more important for your home and way of life. In order to maximize comfort while reducing energy use, consider how your choice of roofing material and roof color can interact with your schedule and environment. You don’t need to know every solution. At Four Seasons Roofing in Seattle, we’re ready to assist.

Factors Beyond Roof Color

However, the color of the roof is not the only factor to consider. The items listed below also affect how comfortable your house is to maintain:


Your home’s daytime heating will depend on the conditions outside. You will be in the shade if you are near trees or in a small valley, which could have a chilling effect.


Color is obviously ineffective if there is lot of snow on your roof because the sun cannot penetrate it. Calculations are also significantly impacted by clouds.

North, East, South or West:

It goes without saying that direct sunshine will warm your house, but the amount of effect varies depending on the time of day and the season. Northern-facing roofs will receive less sunlight, whereas southern-facing roofs could receive a lot more. The cooler morning light will be absorbed by an eastern exposure, and the warmer afternoon light by a western exposure.


Color can be affected by material compositions. Asphalt shingles are one example of a modern roofing material that has specific coatings to control solar gain and may be labeled as Energy Star.


The ability of the roof to retain heat is significantly influenced by the material’s overall density. For instance, heavy natural slate retains temperature longer than lighter synthetic slate.


Glossy roofing materials are cooler than matte ones, even if they are the same color.


In addition to how the color of the roof influences a home’s temperature and energy usage, there is another issue to take into account. Certain roofing materials are more susceptible to temperature than others. This means that the durability of the actual material may be impacted by the color you choose.

The Upshot

In the Greater Seattle area, attic insulation and roof ventilation have a significantly greater impact on a home’s interior temperature than the color of the roof.

Your climate will ultimately influence how much roof color affects energy efficiency. In the Pacific Northwest, where there is a lot of tree cover and an overcast maritime climate, the effect of the sun is reduced for a large portion of the year, increasing the variety and flexibility of roofing color choices. Generally speaking, as long as your property is correctly engineered, you can choose any color for your roof in this area.
