What Is Cool Roof and How It Works?

As people become more conscious of home energy efficiency, reflective roofing is becoming more popular. What exactly does reflective roofing–also referred to as "cool roof"–entail? How does it differ from roof coatings and painting the roof white?

Reflective roofing is one type of roofing installation that concentrates on keeping homes cooler than a conventional roof could.

The cool roofs reflect light and absorb less solar energy, which, in turn, lowers the home's temperature.

How Do Cool Roofs Work?

By combining different materials and the aid of a special reflective coating, reflective roofs reflect more light than traditional roofs. The coatings are available in a wide range of styles and colors, which means the curb appeal does not have to be sacrificed. They also can reduce the temperature of a house considerably.

Like all roof coatings reflect light, reflective roofs can prolong the life of a roof due to their film coating that absorbs the damage from the weather. It makes roofs energy efficient and cost-effective.

The coatings offer two main advantages. They possess high levels of thermal emission, which means they're able to release heat. In addition, due to the solar reflection, they help reflect light away from the house. Together, these factors help ensure that your home is cooler.

What Are the Benefits of a Reflective Roof?

In some ways, reflective roofing is a great way to reduce your energy costs. However, it's essential to talk to an expert and set realistic expectations if that's the primary objective.

Furthermore, reflective roofing will make your roof last longer. This is because you're providing a layer of protection. Reflective roofing can lower the temperature of a roof, reduce the long-lasting effects of UV radiation, and lessen environmental harm over the long term by taking away the necessity for regular roof repair and replacement.

Roof coatings also have the advantage of being simple to install. It is important to choose an expert contractor; the process of installation is swift and not loud or demanding. The time required to finish the roof coating depends on the size of the roof; however, generally speaking, from beginning to end, the job can take up between two and three hours.

What Do Reflective Roofs Cost?

The cost of installing reflective roofing is contingent upon the dimensions of the house and the roof.

However, it is considered low for adding reflective coatings on an already existing roofing–beginning at as little as 15 cents for each square foot–and is not a significant cost when applied at the beginning of a roofing replacement. It's because shingles come pre-fabbed with coatings, or homeowners can request the roofing contractor to incorporate this coating in their construction price.

Reflective roofing materials are available in a wide range of choices. Tiles may be glazed, shingles can be treated, wood may be cool-colored, and metal can be coated factory-style. It is important to talk to an experienced roofer regarding reflective roof designs. It's because even a minor pin-hole in the reflective roof coating could cause damage to the entire roof and result in more destruction to your roofing.
