What is an Energy-Efficient Roof? [Infographic]
When we think about energy efficiency, it’s usually through LED lights, smart thermostats, and new tech. But a roof can also be energy efficient through its material, color, and build. The following infographic gives details on “cool roofs” and how they impact energy consumption.
Why it’s Important
A cool roof can reduce surface heat by up to 50 degrees on a hot day. That results in an up to 15% reduction in energy consumption.
Cool roofs can also reduce the Heat Island Effect. The Heat Island Effect is a result of a concentration of buildings in an urban area where dark buildings and roofs collect and retain heat. It’s why cities tend to be a few degrees warmer on average than its outskirts!
Lighter colors reflect more light. Less sunlight equals less heat. But you don’t need a white roof to be energy efficient. There are darker products that are designed to reflect the infrared portion of the spectrum. Since it won’t also reflect visible light, light-colored roofs are still the preferred choice.
Gaining “cool roof” status not only depends on color, but the material used to build the roof. Some roof types to consider:
- Shingle: Shingle roofs consist of overlapping panels. Some are sold with specially coated granules that provide better solar reflectance or can be coated in the field to make them more reflective.
- Tile: Tile roofs can be made of clay, slate, or concrete. Surface treatments can transform tiles with low solar reflectance into cool roof tiles.
- Metal: Painting a metal roof can increase its thermal emittance and solar reflectance, allowing it to achieve cool roof status. Or, you can apply cool reflective coatings.
