Although it primarily serves as a shield against the outside elements, your home’s roof also plays a key role in the structure’s overall efficiency. It can act as a barrier against heat gain in warm weather, allowing your cooling system to operate at peak performance. As such, an energy-efficient roofing system helps create a more comfortable living environment and reduces utility costs. Here are some of the most effective roof improvements you can make to achieve a higher efficiency level.  

How to Increase Your Roof’s Energy Efficiency

1. Select a Light-Colored Roof 

Dark roofs absorb a great deal of sunlight and heat. This can raise indoor temperatures substantially and cause your air conditioner to work overtime to keep your home cool. In contrast, lighter shades naturally reflect heat away from a building. Thus, light-colored roofs are a more suitable selection for hot climates. 

2. Look at Alternative Materials

While asphalt shingles tend to be popular among homeowners, they may not be the most energy-efficient roofing material available. As an alternative, you might consider metal or tiles. These are rated high for efficiency because of their ability to reflect UV rays and prevent heat absorption. When it's time to re-roof your house or design a new building, carefully weigh all your options.

3. Apply a Cool Roof Coating

If you’re not quite ready to invest in a new roof, applying a cool roof coating can be a cost-effective way to give your current system a boost in efficiency. A roof coating involves using a type of paint that contains special reflective pigments. Adding it to the roof’s surface provides enhanced solar reflectance, helping to maintain a cooler temperature. 

4. Ensure Adequate Ventilation 

Roofs need sufficient airflow to keep heat from building up under the surface. When hot air is trapped, it becomes difficult to regulate indoor temperatures, so it’s important to ensure your roof is adequately ventilated. By installing vents along the eaves, cool air will enter, and warm air will escape.
