Cool roof shingles are specifically designed to reflect the sun’s heat. Quite simply, they repel the heat and keep your house cool.

The cool roof shingle you pick for your home significantly affects the entire roofing project, including the installation, cost, and warranty. 

Like most property owners, you are probably considering going with asphalt roof shingles. But do you know there are various brands and types?

Well, if you don’t, you aren’t alone. There are several asphalt shingle brands to pick from. But which to choose?

It’s tough to say a particular cool roof shingle is better than the rest, as all brands manufacture excellent products.

However, some are considered superior by roofing contractors and offer homeowners greater variety to create the roof they desire.

To help you wade through the sea of options, we are analyzing the best cool roof shingles you can choose for your home.

The Main Types of Roof Shingles

Before we discuss the best cool roof shingles for your home, let’s explore the basic types of roof shingles on the market today.

They include:

  • Asphalt shingles: They combine an asphalt layer, a fiberglass mat, and ceramic granules. Due to their cost-effectiveness and ease of installation, they’re the most popular on the market.
    They are available in a variety of colors and styles, allowing for aesthetic customization.
  • Composite shingles: These are made from recycled materials like rubber and plastic. They can last up to 50 years, thanks to their high weather and impact resistance.
  • Metal shingles: They are highly advantageous due to their fire and algae-resistance capacity. Also, they are easy to maintain.
  • Slate shingles: They are made from slate, a natural and durable stone. If maintained well, these shingles can last up to 200 years.
  • Solar shingles: Besides being a roofing material, solar shingles are also a clean energy system.
    Therefore, they are ideal if you want access to solar energy without installing the traditional solar panels.
  • Wood shingles: They are made from trees such as Pine, Redwood, and cedar. These shingles come with a distinctive rustic look and feel that’s hard to reflect with the other shingles.
    Also, they are highly durable and can last between 40 and 50 years.

Cool Roof Costs 

When it comes to determining the cost of cool roof shingles, you need to consider a couple of factors.

The first and foremost is the size of your home’s roof. Of course, the more roofing material is required, the more you will need to spend on your cool roof solution.
