How Metal Roofs Affect House Temperature

Benefits of Metal Roof in Extreme Temperatures Metal roofs have become increasingly popular among homeowners, especially now that they’re available in a much wider range of styles and finishes than in the past. They are no longer limited to the traditional “barn roof” style. They are more flexible, more attractive and more affordable. And with its energy efficient properties, it is not only good for the environment, but for your wallet too.

Will a metal roof make my house warmer?

A metal roof acts as an insulator and it naturally reflects the sun’s UV radiation. This will keep you home cooler in the summer and warmer in the winter. You can increase its reflective properties by painting a metal roof in a light color such as white. On the other hand, asphalt shingles and many other roofing materials absorb the sun’s energy making your home hotter and increasing your energy bills.

Cooler Indoor Temperatures During the Summer

Metal roofing not only keeps your home warm during winter, but it also keeps your home cool during hot summers. Many manufacturers are now treating their metal roofs with a special paint that reflects the sun’s rays, called Cool Roofs. Typically, traditional roof temperatures can rise to as much as 150°F during the summer. But cool roofs are up to 50°F cooler, according to the U.S. Department of Energy. A home with a cool metal roof will stay cooler and the air conditioning will run less often. This translates into less wear and tear on the A/C and lower utility bills. Plus, spaces that are typically not air conditioned like the attic and garage, for example, will also stay cooler in the summer.

Metal Roof BenefitsLow Maintenance

Depending on the material, traditional roofs typically have a 15 to 30-year lifespan. But a metal roof can span 40 to 50 years or more before needing replacement. Also, metal is naturally resistant to termites and pests. And since metal roofs reflect water, roof leaks are a rare occurrence. The reflective paint coating that is applied will also prevent rust. Its re-application every few years is virtually the only maintenance a metal roof will require to maintain a like new appearance.


Metal roofs are available in an array of trendy colors and styles that replicate any type of roof like clay tiles, slate, and shingles, to name a few. Homeowners have the flexibility to create the curb appeal they desire.

Whether you’re building a new home or replacing your current roof, be sure to consider metal roofing as an option. A metal roof is not only cost-effective, it also has energy efficiency benefits that make it a comfortable and attractive choice.
