When it comes to energy efficiency in metal roofing, one color reigns supreme. Metal roofing is a popular choice for many homeowners, as it is both aesthetically pleasing and cost-effective. However, the color of the roofing can have a significant impact on its energy efficiency. In this blog post, we will explore which color of metal roofing is the most energy efficient, and why.
Why Energy Efficiency Matters in Metal Roofing
When it comes to choosing a color for your metal roofing, energy efficiency is an important factor to consider. Energy efficiency matters in metal roofing for several reasons.

Did you know that all the painted metal roofing panels we sell are considered “cool roof”, energy-efficient colors? In fact, according to the Metal Roofing Alliance, a “cool” metal roof will save up to 40% on the energy costs to cool your home! Check out our color options on our Color Page
First and foremost, an energy-efficient metal roofing color can help reduce your energy consumption and lower your utility bills. By reflecting sunlight and reducing heat absorption, an energy-efficient color can keep your home cooler in the summer and reduce the need for air conditioning.
Lifespan of Roof
Additionally, an energy-efficient metal roofing color can also help extend the lifespan of your roof. Heat absorption can cause the roofing material to expand and contract, leading to cracks, leaks, and premature aging. By choosing a color that reflects heat, you can minimize the stress on your roof and increase its durability.
Helps the Environment
Furthermore, energy efficiency in metal roofing is also beneficial for the environment. By reducing your energy consumption, you can lower your carbon footprint and contribute to a more sustainable future.
In summary, energy efficiency matters in metal roofing because it can save you money, prolong the life of your roof, and reduce your impact on the environment. So, when considering the color of your metal roofing, make sure to prioritize energy efficiency for a more efficient, cost-effective, and eco-friendly home.
How Color Affects Energy Efficiency of Metal Roofing
When it comes to energy efficiency in metal roofing, the color you choose can have a significant impact. The color affects how the roof interacts with sunlight, heat absorption, and overall energy consumption.
Light vs. Dark
Firstly, the color of your metal roofing determines its reflectivity. Lighter colors reflect more sunlight and heat, keeping your home cooler. This reduces the need for air conditioning and can significantly lower your energy bills. Darker colors, on the other hand, absorb more heat, making your home warmer and increasing the reliance on cooling systems.
Emissivity
Secondly, the emissivity of the color affects how well it radiates heat. Colors with higher emissivity release absorbed heat more efficiently, preventing heat buildup in your attic and throughout your home. This helps to keep your home comfortable and energy efficient.

Solar Reflectance
Lastly, the solar reflectance (SR) of the color measures its ability to reflect solar heat. Higher SR values indicate a more energy-efficient color. By choosing a metal roofing color with a high SR, you can minimize heat absorption and ensure a cooler home environment.
In summary, the color of your metal roofing plays a crucial role in its energy efficiency. By opting for light-colored roofing with high reflectivity, emissivity, and SR values, you can create a more energy-efficient home, reduce your energy consumption, and lower your utility bills.
Most Energy Efficient Colors for Metal Roofing
Let there be Light
When it comes to choosing the most energy-efficient color for your metal roofing, there are a few standout options. Light-colored roofs, such as our Sandstone, Aged Copper or Dove Gray, are known for their high reflectivity and low heat absorption. These colors significantly reduce the amount of heat that enters your home. By keeping your home cooler, light-colored roofs can help you save on energy bills and reduce the need for air conditioning during hot summer months.
Keep it Cool
Another popular choice for energy efficiency is metal roofing in cool colors, such as blues and greens. These colors not only have high reflectivity but also have the advantage of being visually appealing and blending well with natural surroundings. Cool colors can help create a comfortable living environment while still providing the energy-saving benefits of a reflective roof.
The Dark
While light-colored and cool-colored roofs are the most energy-efficient options, it's important to note that darker colors can still be energy-efficient if they have high reflectivity and emissivity values. For example, some dark-colored roofs are designed with reflective pigments that can still reflect a significant amount of heat.
In summary, the most energy-efficient colors for metal roofing are light-colored roofs like our Sandstone, Aged Copper or Dove Gray, as well as cool colors like blues and greens. However, it's essential to consider the specific reflectivity, emissivity, and solar reflectance (SR) values of each color to determine its overall energy efficiency. By choosing an energy-efficient color for your metal roofing, you can enjoy a more comfortable home, lower energy bills, and a reduced environmental impact.
