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.
