The phrase "cool roof" may sound like it's describing the most fashionable, hip cover for your home. But in fact, a cool roof is one that's designed to keep your home cooler during the hot summer months. This results in lower AC bills, which is good for your finances and for the planet. If a cool roof sounds appealing to you, here's a closer look at what this roofing option entails.

What is a cool roof made from?

There are several different kinds of cool roofing materials. There are shingles that look very similar to traditional asphalt shingles, metal roofing systems, tiles, and even rubber-like membrane roofs that are usually used on commercial buildings and apartment buildings.

You can choose your cool roof material based on the climate-directed needs on your area. In areas with heavy snowfall in the winter, metal roofs are often preferred since the snow will slide right off of them. Heavy tiles work well in areas where hurricanes are common.

How do cool roofs keep homes cool?

There are two different means why which cool roofs keep heat from entering the home:

Reflection

Most cool roofs are made from reflective materials. They are either metallic, light-colored, or both. As a result, most of the heat from the sunshine is reflected away from the roof rather than being absorbed through it.

Insulation

Cool roofs are also made with a good layer of insulation. This helps further reduce the amount of heat transferred through the roof. The insulation may be built into the actual roofing material, as with cool shingles, or it may be placed directly under the roof, as with metal panels.

What are the advantages of cool roofing?

Most electricity in the United States is created by burning fossil fuels, like coal and oil. This creates air pollution and also diminishes these limited resources. Cool roofs save electricity by keeping a home cooler and reducing the need for air conditioning. This makes them an eco-friendly choice. Of course, you also save money because your home consumes less energy.

Cool roofs also tend to last longer. Heat damages most roofing materials -- especially shingles. The fact that these roof materials are made to reflect heat rather than absorb it means they are less prone to damage and decay. You may not have to get repairs as often.
