Atlas Roof Shingles: Slate and Three-Tab

When it’s time for a roof repair, your choice of shingles matters as much as your choice of roofers. With plenty of manufacturers on the market, you might be wondering which roof shingles are best, and it’s a good question. Well, as the fourth-generation of roofers in my family, I’ve come to use one manufacturer and one manufacturer alone: Atlas. To put it simply, I only trust Atlas roof shingles when it comes to my customers’ homes. Under the Atlas umbrella, however, you have a lot of options. That’s why, in this post and the next, we’re looking at what each of the different types of Atlas shingles has to offer.

When it comes to Atlas roof shingles, there are three basic styles: “slate,” “three-tab,” and “architectural.” We’ll dive into slate and three-tab here. But choosing your shingle style will depend on a variety of factors including budget, aesthetics, and local weather. Regardless of what you pick, however, me and my team’s experience as roof repair professionals has taught us that Atlas just doesn’t make bad shingles.

Atlas GlassMaster shingles are a solid roofing and roof repair option. That’s because they combine great value with an Atlas roof shingles 30-year limited warranty. Additionally, their Class A wind resistance, algae-resistant design, and eligibility for a Signature Select Warranty upgrade make these a great choice for a wide variety of homes. Overall, it’s easy to see why GlassMaster shingles are one of the best options for homeowners who want security without breaking the bank.

Atlas StormMaster Slate shingles are a premium option from the company. These are hands-down the best slate shingles Atlas makes. StormMaster Slate shingles come with all of the key features you can expect in Legend® three-tabs and then some.
