Energy efficient options are all the rage, especially these days. By choosing more energy efficient options, this can reduce climate change, making our home planet a safer and healthier place to live. Truly every little bit of energy savings counts. Speaking of energy efficiency, did you know that metal roofs are energy efficient? You might have thought they were the opposite, but in reality, they’re one of the most energy efficient roofing materials out there known to man!

Here are some energy efficiency facts about metal roofs that might encourage you to want to make the switch:

They Have a Higher Thermal Performance By Up to 218%

Believe it or not, metal roofs have a greatly increased thermal performance when compared to their asphalt shingle counterparts. Thermal performance is defined by how well something is able to resist heat. Why is good thermal performance so important, you might ask? The higher the thermal resistance of your home or building, the lower its heating and cooling load will be. As a result, you can reduce the energy usage inside your property.

Metal Roofs Re-Emit as Much as 90% of Solar Radiation it Encounters

Roofs that absorb solar radiation make the building below it hotter. On the flip side, roofs like wasatch steel metal roofs that re-emit about 90% of solar radiation it comes in contact with, re-radiates the energy to keep the building below it cooler. A cooler building means less energy use. But how does re-emitting solar radiation work? When solar radiation is re-emitted, its wavelengths travel in all directions. The Earth’s surface and atmosphere then reabsorb that energy.

You Can Save Up to a Whopping 40% in Energy Costs

Money might not be everything, but at the same time, it is. It makes the world go ‘round. As we’ve discussed, a roof with higher thermal performance and a greater amount of solar radiation that it re-emits into the atmosphere, can keep a building cooler. In turn, this can reduce your need to use energy to maintain the temperature of your home or building. With less energy needs on your property, this can help you save on energy costs. Saving money feels and looks so good! And better yet, you’ll feel great knowing that you made a difference for the planet you live on by having a more energy efficient home.

As a bonus, having a more energy efficient home by installing a metal roof can also boost the value of your home and make you eligible for large home insurance premium discounts. Metal roofs may not be cheap, but they are durable, long-lasting, weather resistant, and of course, energy efficient, which make them an excellent option.


You might have thought metal was a bad material to use for the roof of your home or commercial building. In truth, it can be quite an energy efficient option. From improving thermal performance, to re-emitting solar radiation, to helping you save significant energy costs, having a metal roof is a great choice.
