Why an Energy Efficient Roof is a Must (plus the Best Materials)

Is your home too hot in the summer and too cold in the winter? Are your electric bills high all-year-round? If so, it’s probably because you have a roof with low energy efficiency.

The solution to your problem is in making your roof energy-efficient, and this article will show you the best ways to do it and the materials to use.

Why You Should Have an Energy-Efficient Roof

Why is energy-efficient roofing so important? The asphalt shingles that are commonly used for roofing accumulate a lot of heat during the summer. Because of this, the heat is transferred into the interior of your home.

It doesn’t only make your home unbearably hot, but you then need additional cooling, which racks up your energy bill. And then we are not even mentioning the carbon dioxide emission, increasing your carbon footprint!

Energy-efficient materials are made to reduce the absorption of heat during spring and summer. Making your roof more energy-efficient would:

  • Save money
  • Help your roof last longer
  • Contribute to more sustainable living

What Makes a Roof Energy-Efficient?

Deciding on the best roofing materials can be difficult because there are so many available materials on the market. All of these materials make your home more energy-saving, and this pays off long term because you’ll spend less on heating and cooling.

The two essential traits of energy-efficient materials that enable this are emittance and reflectance.


Reflectance is a trait of reflecting sun rays away from the material rather than absorbing it.


Emittance is a material’s ability to prevent accumulation and radiate the heat away into the environment. This reduces roof temperature.

Best Materials to Use for Energy Efficiency

So, what are the best materials to use for roof energy efficiency? You can choose between the following options:

  • Composite shingles look similar to asphalt shingles, but they’re more emitting and reflective. With composite shingles, lighter colors indicate bigger energy savings. However, they can get distressed over time and start to look worn down and dirty.
  • Photovoltaic cells. These cells are used to create a solar roof, and they convert sunlight into energy that you can use in your home.
  • Metal shingles. Highly energy-efficient materials, like metal roofing, have a longer life expectancy.
  • A green roof, which is a cheap way to have both a “green” and an energy-saving roof.
  • Cool roof coating, which you can apply to your existing roof.
  • Light-colored shingles. If you’re re-doing your existing roof, you can improve its energy-efficiency by using lighter-colored shingles.
  • Attic Insulation, which improves the energy efficiency of your home and makes it hotter during the colder months. Your attic is responsible for near 50% of heat loss during winter.


Insulation can help reduce heating costs and protect the health of your roof. You should apply insulation materials instead of attic flooring, using either batt/blanket or loose-fill either over the existing insulation or over an uninsulated attic.

  • Loose-fill insulation is best for attics with obstructions or irregular joist spacing, as well as over existing insulation.
  • Blanket insulation, or batts, are packages of insulation with different thicknesses that you fit between joists and studs of the roof framing. They’re best for attics with standard joist spacing and those without insulation.

The Verdict

Re-doing your roof so it is more energy efficient is a great idea to save costs and contribute to preserving the environment.

You can choose between adding energy efficient shingles and insulation to your existing roof or completely re-doing it using highly efficient materials.

If you’re up for a bigger investment, you can also consider installing a solar roof or building a green roof.
