What Are Architectural Shingles? Homeowner’s Guide

Whether you’re building a new home or considering a roof replacement on your current one, you’ll need to decide what type of roofing materials to use. There are several options out there, from metal roofs to wood shingles and shakes to clay tile to traditional asphalt shingles and architectural shingles. But which will be best for you?

Asphalt shingle roofs are typically the most cost-effective option, but within that category, you have more options. Should you choose 3-tab or architectural shingles? Three-tab used to be the only type available, but that changed around the 1980s when new technology and manufacturing techniques allowed for a more advanced and durable design.

Today, architectural shingles are the most popular when it comes to asphalt roofing. They can mimic the appearance of wood shake, slate, and other types of roofs, and they have a more updated look compared to the traditional 3-tab shingles.

You can, however, still choose 3-tab shingles if you want to. It all depends on your goals for your home. Keep reading to learn more about architectural shingles, how they differ from standard shingles, and how installation works.

What Are Architectural Shingles?

Also called “dimensional,” “laminated,” or “dragon tooth” shingles, architectural shingles are the most commonly used roofing shingles in home construction today. They came onto the market in the 1970s and ’80s to give homeowners the option of creating a more unique and stylized look.

Architectural shingles can mimic the appearance of other types of roofs, such as a wood shake or slate roof. They have a distinct, dimensional appearance that typically looks more attractive and updated as opposed to the older style 3-tab shingles.

However, they cost more, so it’s important to think about your priorities when deciding which type of shingles to go with.

How Do Architectural Shingles Differ from Standard Shingles?

Both 3-tab and architectural shingles are made of asphalt and adhesives, with fiberglass for the backing and granules for the outermost layer.

Standard shingles—the original roofing shingles—are called “3-tab shingles” because they’re made of a single layer of asphalt-coated fiberglass with cut-outs forming three individual tabs. These tabs fit together like puzzle pieces during installation, creating a uniform, flattened pattern of rectangular shingles.

3-tab shingles have been around for a long time. Their simple design makes them easy to install and repair, and also makes them the most affordable in terms of upfront costs. However, they have become less popular over time, for two primary reasons: their plain, flat look and because they aren’t as durable as other types of shingles.

Architectural shingles are also made of asphalt-coated fiberglass, but they have multiple layers. This is what gives them their dimension, and also what makes them thicker and more durable than 3-tab shingles.

They have no tabs or cutouts, but their lower portions are laminated. They have an additional asphalt layer that creates the contoured look, while an asphalt sealant bonds the layers.

In general, architectural shingles are about 50 percent heavier than 3-tab shingles and have more granules on the top surface. Most are made of a higher-quality asphalt material as well.

3-Tab Shingles vs. Architectural Shingles: A Comparison

If you’re trying to decide between these two types of shingles, consider the following comparisons.

Durability and Lifespan of 3-tab vs. Architectural Shingles

When thinking of short-term costs, 3-tab shingles seem like the best option. When you consider long-term durability, however, architectural shingles win out.

That’s because architectural shingles are more durable and will last longer. They cost more initially, but they can save you money down the road in repair and replacement costs. As they’re thicker and made of higher quality materials, they can last anywhere from 20 to 30 years, or from 25 to 40 years for premium architectural asphalt shingles.

In contrast, 3-tab shingles typically last from 10 to 20 years, depending on the weather conditions where you live. In areas of mild climates, they can last longer—up to 25 years.

Weather Resistance of 3-Tab Vs. Architectural Shingles

When considering what type of shingles to use on your new roof, it’s wise to consider the climate you live in. If you live in a mild climate, you’re more likely to be happy with the economical 3-tab shingles than if you live in a climate that is prone to bad weather.

High winds, in particular, can be a concern when it comes to your roof. In general, 3-tab shingles are rated for winds up to 60 miles per hour. Architectural shingles, on the other hand, because they are heavier and thicker, are typically rated for winds between 80 and 120 miles per hour.

Architectural shingles also stand up better to other climate conditions such as heat, snow, ice, and rain. They are more water resistant because they are laminated and coated in fine, tightly packed granules.

Erie Home architectural asphalt shingles have a strong bond that ensures maximum protection against wind uplift, blow-off, and water damage. They’re also rated to provide wind protection up to 130 mph.

Maintenance of 3-tab vs. Architectural Shingles

Both types of roofing shingles will require regular maintenance to help catch any problems early and to increase longevity. In general, architectural shingles will require less maintenance than 3-tab shingles, as they are less likely to be damaged or to start to leak.

It is wise with any type of roof, however, to perform the following types of maintenance:

• Inspect your roof twice a year (spring and fall) for damage, cracking, staining, fading, and buildup.
• Clean your gutters and downspouts.
• Trim tree branches away from the home.
• Clean off any dirt and algae.
• Address any needed repairs as soon as possible.

Warranty of 3-tab vs. Architectural Shingles

Because of their higher quality and lasting durability, architectural shingles typically come with better warranties than 3-tab shingles. Most companies will provide a 25-year warranty for 3-tab shingles. This usually covers things like manufacturer defects, with limited protection against fire, algae, and wind damage (up to 60 miles per hour).

Warranties for architectural shingles are usually much more robust, providing protection against wind, fire, and algae. At Erie Home, we back our architectural shingle roofs with a 30-year limited lifetime transferable warranty that protects against any manufacturing or installation defects that result in water penetration. 

The Appearance of 3-tab vs. Architectural Shingles

When it comes to which type of shingle will look best on your home, architectural shingles have the advantage. While 3-tab shingles have a flat, uniform appearance, architectural shingles have a more dimensional look that increases curb appeal.

However, some people may prefer the cleaner, flatter look of the 3-tab shingle, depending on the type of home or other structure where the roof will reside. They do come in a wide variety of colors, so it’s usually easy to match the look and feel of the house or other building.

Architectural shingles come in a much broader spectrum of colors than 3-tab shingles and are made in various shapes and sizes. You can get those that mimic other popular roof styles like slate or cedar shake without having to pay the higher costs of the real materials.

As an added bonus, you won’t need additional reinforcements for your roof, as you would with real slate shingles. You also won’t have the flammability concerns of real wood.

What About the Installation of 3-tab vs. Architectural Shingles?

Because of their complexity, architectural shingles should be installed by roofing professionals. In contrast, homeowners with roofing knowledge may be able to install their own 3-tab shingles, although hiring a professional installer is generally the safest way to go in either instance.

Improper or careless installation can add stress to a roof and cause damage, leaks, and other problems.

In general, 3-tab shingles are easier to work with. They’re thinner, lightweight, and more flexible, so they’re easier to manipulate. They come in strips of three, which reduces the amount of work installers have to do when laying them out and nailing them down.

Architectural shingles, on the other hand, are heavier and bulkier, which means they require more effort to carry around during installation. It’s best to consult with an expert to make sure your roof is strong enough to support them before you start.

They come packaged individually, so they take more time to install. However, because they usually last longer, you won’t have to worry about replacing them as often.

Are 3-Tab Shingles Being Phased Out?

One more thing to consider in your roofing choice is that 3-tab shingles appear to be losing favor in the home-building industry. Because architectural shingles offer so many advantages, they are the preferred choice.

In some cases, this can make it harder to find the color of shingles you want, as it seems this type of shingle is gradually being phased out.

That doesn’t mean you can’t still get 3-tab shingles at the time of this writing, but you may not be able to find as many color options, or you may find that some suppliers have stopped carrying them altogether.

Frequently Asked Questions

What is the difference between shingles and architectural shingles?

Standard shingles—also called 3-tab shingles—are made with one layer of asphalt-coated fiberglass, whereas architectural shingles have multiple layers.

Architectural shingles are an updated design of 3-tab shingles and are more durable and wind-resistant. They also come in a wider variety of color and style options, but they are more expensive.

What are the pros and cons of architectural shingles?

Architectural shingles have many advantages and only a couple of disadvantages when compared to standard, 3-tab shingles.

Pros

• Durability: Because they’re heavier and thicker, architectural shingles typically last longer than 3-tab shingles.
• Weather-resistance: Architectural shingles can better withstand high wind, heat, ice, snow, and rain.
• Aesthetics: Architectural shingles are considered more attractive as they offer a layered, dimensional look to the roof. You will also have more customization options in terms of shape and size.
• Warranty: The warranty on architectural shingles is typically longer and more robust than that for 3-tab shingles.

Cons

• Cost: Architectural shingles are more expensive up-front than 3-tab shingles, and the initial cost of installation is typically higher. However, they do last longer, and may save you money on repair and replacements in the long run.
• Weight: Architectural shingles are heavier than 3-tab shingles, so it’s important to make sure your home will support the additional weight before installing them. In some cases, they may require additional structural support.
• Not recommended for low-pitched roofs: If you have a low-pitched roof—when the pitch is below 2:12, meaning the roof is less than 2 vertical units up for every 12 horizontal units out—architectural shingles may not be the best option. Check with your roofing contractor for more information.

What is the life expectancy of architectural shingles?

In general, architectural shingles will last longer than 3-tab shingles. They are generally estimated to last roughly 20 to 25 years, whereas 3-tabs are estimated to last 10 to 20 years.

Are architectural shingles worth the money?

When considering whether architectural shingles are worth the initial higher costs, ask yourself the following questions:

• Do I care about durability? If you’re planning on staying in your home, having a roof that lasts longer may be one of your main concerns. In that case, architectural shingles are the more lasting choice.
• What is my budget like? Three-tab shingles will cost you less to install, so if you’re in a crunch financially, you may need to avoid architectural shingles for now. Keep in mind that if you work with a professional roofing company like Erie Home, you may be able to take advantage of financing options.
• How much do aesthetics matter to me? Architectural shingles will give you more options when it comes to designing your roof. They are the better option for improving your home’s curb appeal.
• What is the weather like where I live? If you live in a mild climate, 3-tab shingles may work fine for you. But if you live in an area with high winds, heavy rains, and snowy winters, you will be happier with architectural shingles. They are much better at withstanding wind, heat, rain, ice, and snow.
• Am I planning to sell my home? Having architectural shingles can increase the value of your home. Most home buyers prefer them, so you may be able to get a higher price for a house that has them.

Can I install architectural shingles over 3-tab shingles?

Installing new shingles over old ones can be easier than tearing off the old shingles first. It can also save you money when it comes to dump fees, underlayment installation, and other facets of installation.

It may be possible to overlay architectural shingles over 3-tab shingles, but it is not usually recommended. The two types of shingles come in different sizes and shapes, and the size difference can create uneven or “lumpy” areas on your roof. Any defects on the first layer, as well, can telegraph throughout the new layer.

Architectural shingles are heavier than 3-tab shingles too, and will add more weight to your roof, so you’ll need to be sure your structure can endure the extra load. Most building codes limit roofing to just two layers. On some homes, the extra weight could cause the decking to sag.

There are a few other reasons why it’s not recommended to “roof-over” a layer of 3-tab shingles:

• Harder to inspect: If you don’t remove the existing layer of shingles, it’s harder to inspect your roof for any potential issues that could cause leaking down the road.
• Can’t replace underlayment: The underlayment between the shingles and the roof decking prevents water from entering the attic. If your underlayment is worn out or damaged, it won’t protect your desk from any water that gets past the shingles.
• Voided warranty: Some roofing warranties will not allow a second layer of shingles. Check with the manufacturer first.
• Reduced home value: If you want to sell your home in the future, beware that new homeowners may consider a two-layer roof a disadvantage. One reason for this is because they would have to pay higher costs to remove the layers if they want to replace the roof later on. They will also have to accept the risk that there is damage somewhere underneath that can’t be seen.
• Can be costly: While re-roofing may save you costs upfront, it can result in increased repair costs down the road. Having the old shingles stripped and replaced with new layers creates a longer-lasting roof.

How do I know when my roof needs to be replaced?

Look for the following signs that your asphalt roof may need to be replaced:

• Signs of damage: You can see that some of the shingle edges are curled, missing, or cracked, or you notice moss or algae growing underneath the shingles.
• Age: If your roof is 20 years or older and looks aged and worn, it may be time to replace it.
• Water leaks: Water leaks indicate a problem in the roof. Try to repair it as soon as you can. If you have multiple leaks, it’s time for a new roof.
