What Makes a Roof Energy-Efficient in Greenville?

You know how important a good roof is to your well-being. An energy-efficient roof does more than provide shade for you. Whether you want to reduce the heating expense in your house or improve the environment by saving energy throughout the year. To determine the energy efficiency of your roof, consider these two factors.

Solar Reflectance Index (SRI)

The solar reflectance index measures the roof’s ability to reflect the heat from the sun and release any heat absorbed. The higher the SRI number, the better. Roof shingles that fall under the energy star label require a minimum of 25% reflectance rate. Using the right shingle color would help increase your roof’s solar reflectance index.


A well-ventilated building improves the quality of life in the house. Like the lungs, every home needs ventilation to keep on living. One of the important ways to ensure a well-ventilated home is by installing energy-efficient roofing shingles. When a roof is well ventilated, it’s a sign of higher energy efficiency.

Most Energy-Efficient Roof Materials

It’s possible to spend a lot of money on air conditioning and other cooling systems. Your roofing material goes a long way in helping to reduce the cooling expense. There are a lot of roofing materials available, but not all are suitable for your home. Here are the best roofing types for energy efficiency.

Concrete or Tile Roofs

Concrete tiles are one of the most durable roofing materials available. A concrete roof can last as long as 50 years, giving you the best value for money. They come in different styles and colors. This roofing material takes a long time to heat, which means it will take longer for the heat to leave through your roof.

Clay tiles are eco-friendly because they’re made from natural materials. They keep your home cool by reflecting the UV sun rays.

Asphalt Shingles

Asphalt shingles are one the most commonly used roofing materials among homeowners throughout the United States. They’re made of fiberglass granules. Asphalt shingles are low maintenance and energy-efficient. When you’re considering buying energy-efficient asphalt shingles, you should look for the ENERGY STAR rate of the shingle. The higher the energy star rating, the better its energy efficiency.

Solar Roof Tiles

The roofing materials in this article focus on reflecting the sun’s UV rays. However, the solar roofing tiles convert the sunlight into a renewable energy source you can use to power your home. Solar roof tiles provide another advantage over conventional solar panels; instead of being installed on existing roofs, they’re the roof itself. Solar roof tiles are energy-efficient, although more expensive than other roofing materials.

Cool Roof Coating

On a sunny day, wearing a light-colored dress helps keep your body cool because it reflects most sun rays than a darker dress. It’s the same with a cool roof coating. Cool roof coatings are white or special reflective paints that reflect sunlight. They’re thick paints applied to the surfaces of the roof to reflect the sun’s UV rays.

Cool roof coating has a lot of benefits for the homeowner, including the following.

  • Reduce energy costs.
  • High solar reflectance index (SRI).
  • Simple and fast application.

Roof Insulation

You should feel warm and comfortable in your house. But if your home is not adequately insulated, you might be losing heat and money. Proper roof insulation prevents excessive heat from entering the house and keeps the house warm.

Roof insulation’s purpose is to reduce the overall loss in the house by adding materials with low heat conductivity between the roof and the attic. There are many types of roofing insulation you can choose from. They include:

  • Spray foam insulation.
  • Rigid insulation boards.
  • Batt insulation.
  • Loose-fill or blown-in insulation

Insulating your roof brings long-lasting comfort and improves your home’s energy efficiency. Insulation also acts as a barrier to heat flow, which helps maintain consistent heat in the house. However, before you choose to insulate your home, consult your local Greenville roofing experts on a suitable material for your roof.
