What Kind of Roof is Most Energy Efficient?

When it comes to choosing the most energy efficient roof for your home or business, your first consideration must be the climate in your local area. If you live in a cold climate, you’ll want to choose a roof material that is best at keeping your home or business warm during the long winter. But if you live in Texas or any other warm climate, your first priority will undoubtedly be keeping your living or work environment as cool as possible during the majority of the year when the weather is warm or downright hot.

Fortunately, the federal government has created a rating system that enables all of us to choose the most energy efficient materials. Developed by the U.S. Environmental Protection Agency and the U.S. Department of Energy, products that have earned the ENERGY STAR rating have proven that they meet the strict guidelines and standards developed by these two federal agencies. The first thing to look for in any roofing material is an ENERGY STAR rating.

Although there are several different types of roofing products that have earned the coveted rating – asphalt, ceramic, composite and concrete, to name a few – there is one material that stands out as being the most energy efficient choice for warm climates, and that material is metal. You’ll find a wide variety of metal roofs available: from panels to tiles to an assortment of other configurations in steel, aluminum, copper and even stainless steel. Whichever type of metal roof you decide on, you’ll gain several benefits from this durable, energy efficient material.

What Makes Metal Roofing Best


  1. Metal reflects the hot rays of the sun.

    As opposed to some other materials that actually absorb heat and make the building underneath warmer – such as asphalt, for example – metal does just the opposite. The more heat is reflected away from the roof, the cooler the building will be. And the cooler the building is, the less money you’ll have to pay to your local utility company for air conditioning. In fact, a metal roof can save a business or homeowner as much as 50% in cooling costs.
  2. Lighter colors are best.

    Darker colors absorb heat more readily than lighter shades. Just think about how much hotter a dark asphalt parking lot is during the summertime than your lighter-colored concrete driveway, for example. When choosing a color for your new metal roof, go for a lighter shade to optimize its energy efficiency.
  3. You’ll save money in the long run.

    Although there’s no doubt that metal costs more than many other materials, the amount you’ll save over a period of years will more than make up for the initial outlay. Not only will you spend less on utilities during the warm months, but you’ll more than likely qualify for some tax credit options and lower insurance premiums. Many times, a metal roof can be installed directly over an existing roof, which eliminates the cost involved in tearing off and hauling away the old roof. Finally, metal roofs last much longer than many other materials, which means you won’t have to pay money to have the roof replaced a few years down the line.
  4. Metal is fireproof.

    In warmer climates that are more susceptible to droughts, fire safety is always a concern. The fact that a metal roof is resistant to fire not only makes it safer, it usually reduces your insurance premiums and increases the value of your home or business.


If you’re in the market for the most energy-efficient roof for warm and hot climates, be sure to look into the many styles and types of metal roofs available. You may spend a bit more to begin with, but it will pay off in the long run!
