Nothing is worse than the summer heat, especially when you live somewhere hot. It can feel oppressive and inescapable. You have to crank your AC up high just to get relief, but that relief comes at a significant cost, in the form of high utility bills. It can be incredibly frustrating, leaving you wondering what you should do. Do you keep the AC low and suffer that summer heat, or keep paying high utility bills? What if there were a better option?
The answer is right above your head: your roof.
Cool roofs are still a reasonably new innovation. Still, they mean your home will be comfortable even on the hottest summer days, without having to blast your AC or pay astronomical cooling costs.
So, What is a Cool Roof?
The issue with traditional roofing materials like asphalt is that they absorb heat, especially those with dark colors. What you may not consider is that this heat, which can reach temperatures upwards of 150ºF, seeps into the interior of your home, raising the interior temperature. This is why you have to turn up your AC to feel cool, resulting in those higher utility bills.
That’s where cool roofs come in. Cool roofs use special materials and manufacturing processes to reflect more heat and sunlight. It goes beyond the idea of wearing white or light colors in the summer; these roofs are especially designed for hot climates, wear temperatures climb in the summer. With a cool roof installed, heat buildup will lessen significantly, so your home will be a more comfortable temperature, around 55º cooler. With so much of a difference, you should be able to rely less on your cooling system, which is better for your wallet, the cooling system, and the environment.
What Makes a Cool Roof?
Two main characteristics determine if a roof is a “cool roof.” These are:
Solar reflectance (SR): Measures how much sunlight the roof’s surface reflects.
Thermal Emittance (TE): Refers to the roof material’s ability to release the heat it has absorbed.
Materials are rated on a scale of zero to one; one being the most reflective (or emissive) and zero being the least.
More On Cool Roofs
Cool roofs have many benefits worth noting, but the top three to consider are:
1. Cool Roofs Mean Comfort
California, Arizona, Texas, and Florida are just a few states that aren’t strangers to oppressive summer heat. A cool roof on homes in these states will help reflect most of the UV rays and heat, which means significantly less heat seeps into the home and creates a temperature change. In other words, your home will be naturally cooler, so you won’t rely so much on your noisy cooling system. Of course, this is great because it means your energy bills can (and will) be lower, but it goes beyond that.
Having to rely so heavily on a cooling system isn’t good; without a cool roof, that system will have to work twice or three times as hard to help regulate the temperatures inside. This strain can harm the system, and you may need to repair or replace it much sooner than you should have to. Relying so much on it also means consuming more energy, increasing greenhouse gas emissions, and increasing your carbon footprint. With a cool roof, all of that will be a thing of the past.
2. Cool Roofs and the Urban Heat Effect
Have you ever noticed how urban areas are typically much warmer than the more rural ones? That is an example of the urban heat island effect, which causes higher temperatures in urban environments. Temperatures in these areas can be from 1-7º hotter during the day, which may seem minimal, even a single degree can make a difference in some cases.
This phenomenon is a product of our own creation; as urban areas, natural elements like grass, trees, shrubs, and even water are removed to make way for paved asphalt, buildings, and other infrastructure. As a result, there is less shade to protect the area from the sun and more surfaces absorbing the sun’s heat. This increases the temperatures in these areas, making cooling buildings much more difficult and significantly increasing greenhouse gas emissions.
By changing these environments, like installing cool roofing systems, the urban heat effect can be reduced, lowering the temperature in the urban area, and creating a cleaner, healthier environment.
3. Lower Energy Use
As said throughout this article, cool roofs are an excellent option for homeowners looking to save money because they can help lower their energy usage. The fact that these roofs absorb less heat makes this possible; with less heat absorbed, less heat enters the house, keeping it significantly cooler. With a cooler home, you won’t have to run your AC as high as you otherwise would, and will save money on utilities. These energy savings, both the financial and physical, can be even more significant if the area is experiencing a heatwave.
Keeping it Cool
Your roof is one of the most important parts of your home—not just for its appearance, but also for the safety it provides. So, it only makes sense that you want the best material, which may be a cool roof. Fortunately, with cool roofs, there are many options for the typical residential roofing.
Metal Roofing
If you want an industrial look to your home, a metal roof is the way to go. Metal roofs are naturally reflective, but can also be painted with special coatings or light colors that add additional reflectiveness. You can get metal roofs in various styles, including options that mimic asphalt shingles, barrel tiles, slate, and even shakes. It is highly durable, has Class A fire and Class 4 impact ratings, and has strong wind and weather resistance. As an added benefit, metal roofs are an eco-friendly, sustainable, and recyclable option. They are also long lasting, with a lifespan of 40 to 70 years.
Clay and Concrete
Clay and concrete tiles are another popular sustainable choice, often used in hot Mediterranean, tropical, and subtropical climates. Alone, they are naturally reflective, but like metal roofs, there are special coatings to add reflectiveness. They also offer a long lifespan, of anywhere from 50 to 100 years. They are durable and include Class A fire resistance and strong wind and weather resistance. The problem is that they are expensive and heavy, and not every roof can support that weight easily.
“Cool Roof” Asphalt Shingles
Some manufacturers of asphalt shingles offer options with cool roof properties covered in reflective granules. High-quality cool roof shingles can mimic other materials, like slate and shakes. However, they won’t offer the best lifespan or durability, lasting, at most, 30 years.
Synthetic Roofing
Synthetic roofing, such as Brava Roofing Tile product, is growing in popularity because it is a type of roofing that is sustainable, durable, very low maintenance, and long-lasting. In terms of durability, these products often offer Class 4 impact ratings, Class A fire ratings, hurricane-force winds resistance, and more. They typically have UV-resistant qualities and offer special “Cool Roof” colors with special minerals that add more reflectiveness. On top of all that, they can last around 50 years, possibly longer.
Roofs That Make a Difference
Cool roofs are a smart, impactful solution for both homeowners and communities. By reflecting sunlight and heat, they help keep your home cooler, reducing your reliance on air conditioning. That means lower utility bills—potentially saving you hundreds or even thousands—and less energy consumption, which in turn lowers your carbon footprint.
In densely populated areas, like cities, widespread use of cool roofs can significantly reduce the urban heat island effect. With cooler, more regulated outdoor temperatures, buildings need less energy to stay comfortable, which helps cut greenhouse gas emissions on a larger scale.
Though cool roofs are an investment like any other roofing upgrade, they offer lasting value—especially in warm climates—by delivering comfort, savings, and environmental benefits.
Brava’s Cool Roof Tiles are designed to do just that: reflect heat, reduce energy use, and boost curb appeal. Brava combines style, performance, and sustainability—perfect for both roof replacements and new construction projects.
