What Makes a Roof Energy Efficient?
Solar Reflectance Index (SRI)
The Solar Reflectance Index (SRI) is a key measure of how well a roof reflects solar heat. It combines two important properties: solar reflectance and thermal emissivity.
Solar reflectance refers to how much sunlight a roof can reflect away. The higher the reflectance, the cooler the roof stays. On the other hand, thermal emissivity is the roof’s ability to release absorbed heat. A roof with high thermal emissivity cools down faster, preventing heat from transferring into your home.
According to the Lawrence Berkeley National Laboratory, increasing the SRI from 25 to 40 can lower the surface temperature of your roof by more than 13 degrees. This can translate to a 15-20% savings on your energy bill.
Ventilation
Proper ventilation is another crucial factor in making a roof energy-efficient. Good ventilation helps to keep the attic space cool, which in turn keeps your home comfortable.
There are three main types of vents:
- Static Vents: These are simple, non-mechanical vents that allow hot air to escape from the attic passively.
- Wind-Powered Vents: These vents use wind to power a turbine that pulls hot air out of the attic.
- Electric Vents: These are powered by electricity and can move a large volume of air, making them very effective.
A well-ventilated attic prevents heat buildup, which can lead to lower energy costs and a longer-lasting roof.
By combining a high SRI with effective ventilation, you can significantly improve your roof’s energy efficiency. This not only reduces your energy bills but also extends the life of your roof by minimizing heat-related damage.

Types of Energy-Efficient Roofing Materials
Choosing the right energy-efficient roofing material can make a big difference in your home’s comfort and energy bills. Let’s explore three popular options: metal roofing, tile roofing, and asphalt shingles.
Metal Roofing
Metal roofing is a top contender for energy efficiency. Its high reflectivity means it can bounce back a significant portion of the sun’s rays, keeping your home cooler. Metal roofs also have low thermal mass, so they don’t store heat like other materials.
Longevity is another major advantage. A metal roof can last 40 to 70 years, far outlasting other roofing types. Plus, many metal roofs come with coatings that further improve their energy efficiency. For example, DECRA Metal Roofing offers products with reflective coatings that can increase your roof’s ability to reflect solar energy.
Tile Roofing
Tile roofing is another excellent option, especially in hot climates. Slate, clay, and concrete tiles can be very effective at reflecting sunlight. These materials also have a natural airflow under the tiles, which helps to keep your roof and attic cooler.
One downside is that tile has more thermal mass, meaning it can absorb and hold heat. However, many tiles come with reflective coatings that mitigate this issue. You can also apply a light-colored polymer coating to existing tile roofs to boost their energy efficiency.
Asphalt Shingles
Traditional asphalt shingles are not known for their energy efficiency, but advancements in “cool” technology have changed that. Modern asphalt shingles can come with solar-reflecting granules that help reduce heat absorption.
For instance, Owens Corning offers the Cool Roofing Collection, which includes asphalt shingles designed to reflect more sunlight and absorb less heat. These shingles can help you achieve a more energy-efficient roof without sacrificing the traditional look of asphalt shingles.
Choosing the right roofing material can significantly impact your home’s energy efficiency. Whether you prefer the durability of metal, the classic look of tile, or the affordability of asphalt, there are energy-efficient options available.

Benefits of Energy-Efficient Roofs
Cost Savings
An energy-efficient roof can save you a lot on utility bills. By reflecting more sunlight and absorbing less heat, these roofs can lower your cooling costs by up to 25%. For an average home, this can mean savings of $300 to $500 a year.
States and municipalities often offer rebates for installing cool roofs. Plus, you might qualify for a tax credit through the Energy Star rating program. These financial incentives make energy-efficient roofing a smart investment.
Extended Roof Life
Energy-efficient roofs can last longer. By reducing heat absorption, they minimize the wear and tear that high temperatures can cause. This means lower maintenance costs and fewer repairs.
For instance, a metal roof can last over 50 years, thanks to its durability and resistance to heat damage. This longevity translates to fewer replacements and less hassle over time.
HVAC Efficiency
Your HVAC system will thank you for installing an energy-efficient roof. By keeping your home cooler, these roofs reduce the strain on your air conditioning. This not only lowers your energy bills but also extends the lifespan of your HVAC system.
Consistent indoor temperatures mean your system doesn’t have to work as hard, which can save you money on repairs and replacements.
Environmental Impact
Energy-efficient roofs are good for the planet. By reflecting more sunlight and reducing the need for air conditioning, they help lower power plant emissions. This reduces your home’s carbon footprint and helps combat climate change.
These roofs also help mitigate the urban heat island effect, where cities become significantly warmer than surrounding areas. By keeping buildings cooler, energy-efficient roofs can make urban environments more livable.

Cool Roofs vs. Energy-Efficient Roofs
Cool Roofs
Cool roofs are designed to reflect more sunlight and absorb less heat than standard roofs. According to the Department of Energy, a cool roof can lower roof surface temperatures by up to 50°F, reducing the amount of heat transferred into a building. This is particularly beneficial in flat roof and commercial installations, where large surface areas can significantly impact indoor temperatures and energy costs.
Cool roofs often use reflective coatings that can be applied over existing roofs. These coatings improve solar reflectance and thermal emissivity, making the roof more efficient at cooling. In cities with many flat-roof buildings, cool roofs can also help reduce local air temperatures, mitigating the urban heat island effect.
Energy-Efficient Roofs
Energy-efficient roofs encompass a broader range of materials and technologies designed to improve a building’s overall energy performance. These roofs are not limited to commercial applications and can be used in residential installations as well. They focus on two main factors: solar reflectance and thermal emissivity.
Solar reflectance measures how well a roof reflects sunlight, while thermal emissivity measures how efficiently it releases absorbed heat. Together, these properties help keep your home cooler in the summer and can even offer some heating benefits in the winter.
Energy-efficient roofs can be made from various materials, each with its own benefits:
- Metal Roofing: Known for its high reflectivity and durability, metal roofs are excellent for energy efficiency. They can last over 50 years and require minimal maintenance.
- Tile Roofing: Tiles allow air circulation under the roof, which helps reduce heat buildup. They are particularly effective in dry climates.
- Asphalt Shingles: Not all asphalt shingles are created equal. Energy Star-rated shingles, such as those from Owens Corning, offer improved energy efficiency through special reflective granules.
Whether you’re considering a cool roof or an energy-efficient roof, both options offer substantial benefits. Cool roofs are particularly effective in urban and commercial settings, while energy-efficient roofs provide versatile solutions for both residential and commercial applications.
