Asphalt shingles are perhaps the most common type of roofing used in the United States. They’re durable, long-lasting, energy efficient, and look great as well. If you’re replacing your roof you’ve probably noticed that there are two main types of roofing shingles in Marietta to choose from: 3-tab and architectural. If you’re not quite sure which is the best type for your project, here are some things you need to know about the main characteristics of each type.
3-tab shingles get their name from their shape. They have three tabs that go along the long lower edge of the twelve-inch shingle. This type of shingle is the type most people picture when they think of asphalt shingle roofs. They are installed flat along the roof’s decking so the appearance is very non-dimensional and flat with clean lines and a plain appearance. They come in different colors so there’s the option for a little bit of customization.
Architectural shingles are also called dimensional or laminate shingles because of their appearance and composition. Rather than having the three cutouts that 3-tab shingles have, they have the lower portion laminated with an additional layer of asphalt. The end result is that a roof with architectural shingles has more dimension and shape. They come in different sizes and shapes so this adds volume, depth, dimension, and proportion that’s not possible with 3-tab shingles.
Both types of shingles are made up of asphalt and fiberglass granules and adhesive on top of the shingles. There’s a backing underneath this layer for both types as well. The major difference between these two shingle types is how much material is in each shingle as well as the quality of the material. Architectural shingles have a higher quality of asphalt than the 3-tab shingles. They also have more granules on the surface and stronger adhesive to increase the longevity of the shingles. The base is also thicker and stronger. This helps add to the dimensional appearance of the shingles and the intensity is greater because the color distinctions are easier to infuse into the thicker material. The color and texture of 3-tab shingles is much less because they’re very flat and all the shingles are the same size and shape.
Another major difference between these two types of shingles is their thickness and consistency. Architectural shingles are a lot heavier and thicker than 3-tab shingles. While both have a good life expectancy, since 3-tab shingles are lighter and thinner they’re more susceptible to damage in high winds and won’t last as long as architectural shingles.
3-tab shingles are still popular for good reason. Although they’re not as thick as architectural shingles and may need to be replaced sooner, they’re lighter and use less material, which makes them less expensive to purchase and install. Their affordability makes them a great choice for most budgets, and with proper installation they can last up to 15 or 20 years.
One con of architectural shingles is that they cost quite a bit more than 3-tab. Their weight might make them unsuitable for certain buildings without adding to the roof structure first. The benefits are that they’re more aesthetically pleasing, they last longer, and they have a longer warranty.
