The Composition Roof Explained: Everything You Need to Know

Understanding Composition Roofing: What Every Property Owner Should Know

An asphalt composition shingle roof is the most popular roofing material in North America, consisting of a fiberglass mat coated with asphalt and surfaced with protective mineral granules. These shingles are called “composition” because they’re made from a composite of man-made materials—not because they’re different from asphalt shingles.

Quick Answer: Asphalt Composition Shingles Explained

• What they are: Shingles made from fiberglass mat, asphalt coating, and mineral granules
• Why “composition”: The term refers to their composite construction of multiple materials
• Same as asphalt shingles: Yes—the terms are used interchangeably in the roofing industry
• Main types: 3-tab (flat), Architectural (dimensional), and Luxury (premium appearance)
• Typical lifespan: 20-50 years depending on quality and conditions
• Cost: Most affordable roofing option available, ranging $0.80-$1.20 per square foot for materials

If you’re a homeowner or business owner in the Dallas-Fort Worth metroplex dealing with storm damage, planning a roof replacement, or simply trying to understand what’s already on your building, the terminology around roofing can be confusing. Insurance adjusters might call your roof “composition shingles” while contractors refer to “asphalt shingles”—but they’re talking about the same thing.

I’m Dustin Eatman, owner of James Kate Roofing & Solar, and I’ve spent years helping DFW property owners understand and maintain their asphalt composition shingle roofs through insurance claims, replacements, and proactive maintenance. Whether you’re evaluating options after hail damage or planning ahead, understanding how these roofing systems work will help you make informed decisions about your property investment.

What is an Asphalt Composition Shingle Roof?

An asphalt composition shingle roof is engineered for durability, designed to protect your home from the elements for decades. In the U.S., these shingles are predominantly fiberglass-based, starting with a sturdy fiberglass mat. This mat is coated with waterproof asphalt, and a final layer of ceramic or mineral granules is embedded into the surface.

Each layer is crucial to the shingle’s performance. The fiberglass mat provides structural integrity. The asphalt coating provides essential waterproofing. The colorful mineral granules offer vital protection against UV rays, contribute to the shingle’s color, and can include specialized coatings to resist algae. Many fiberglass-reinforced options also earn a Class A fire rating, the highest for roof coverings.

This combination of materials ensures an asphalt composition shingle roof provides excellent weather resistance, making it a reliable choice for homes across North America, including North Texas. To dive deeper into the technical aspects of asphalt roofing, you can explore resources like the Asphalt Roofing – Asphalt Institute.

The Three Main Types of Asphalt Composition Shingles

When considering an asphalt composition shingle roof, you’ll find they aren’t all created equal. They come in various types, each with different aesthetics, performance levels, and price points. Understanding these distinctions is key to choosing the best option for your home and budget, especially given the diverse architecture and weather in the Dallas-Fort Worth Metroplex.

1. 3-Tab Shingles (Traditional Shingles): These are the classic, original asphalt shingles. They are characterized by a flat, uniform appearance with cutouts that make each shingle look like three separate pieces. While still the most economical option, their market share has decreased as homeowners opt for more dimensional styles. Three-tab shingles generally offer a lifespan of up to 25 years.

2. Architectural Shingles (Dimensional or Laminated Shingles): These are the most popular type of asphalt composition shingle roof today. Architectural shingles are constructed with multiple laminated layers, creating a thicker, more dimensional appearance. This layered construction improves their aesthetic appeal, often mimicking wood shakes, and provides improved durability and a longer lifespan, usually around 30 years.

3. Luxury Shingles (Designer Shingles): For the pinnacle of aesthetics and performance, luxury shingles are the answer. These are the heaviest and thickest asphalt shingles, designed to replicate high-end materials like natural slate or cedar shakes at a more accessible price point. Luxury shingles offer the highest level of protection and can have a lifespan exceeding 30 years, potentially reaching 50 years. While they cost more, they deliver unparalleled curb appeal and durability.

To help you visualize the differences, here’s a quick comparison:

Key Components of the Complete Roofing System

Shingles are the most visible part of your asphalt composition shingle roof, but they are just one piece of a larger, interconnected system designed to protect your home. We believe in educating our Dallas-Fort Worth clients about the entire system, as understanding its components helps you appreciate the quality of a professional installation.

Here are the essential elements of a comprehensive asphalt shingle roofing system:

• Roof Decking: The structural foundation of your roof, typically plywood or OSB (oriented strand board), to which all other materials are attached.
• Underlayment: Laid over the roof decking, this acts as a crucial secondary weather barrier, often called “felt paper.”
• Ice and Water Shield: A self-adhering, waterproof membrane applied to vulnerable areas like eaves and valleys. In DFW, this shield is invaluable for preventing water penetration from wind-driven rain.
• Drip Edge: Metal flashing installed along roof edges to direct water away from the fascia and prevent it from seeping underneath roofing materials.
• Starter Strips: The first course of shingles, installed along eave and rake edges to ensure proper bonding, sealing, and wind resistance.
• Flashing: Metal or other durable materials used to seal and protect areas where the roof meets chimneys, skylights, vents, and walls.
• Vents: Essential for attic ventilation. Proper airflow helps regulate temperature, prevent moisture buildup, and extend shingle lifespan.
• Ridge Capping: Specialized shingles used to cover the peak (ridge) of your roof, providing a finished look and crucial protection.

Each component is carefully installed to create a robust, weather-tight barrier for your home. For more detailed insights into our comprehensive roof replacement and installation processes, please visit: More info about roof replacement and installation.

Advantages and Disadvantages of Asphalt Composition Shingles

Choosing the right roofing material for your property in the Dallas-Fort Worth area involves weighing various factors, from aesthetics to long-term performance. An asphalt composition shingle roof is the most popular choice for good reason, but like any material, it has pros and cons. We believe in full transparency, so let’s explore what makes these shingles a great choice and where they might have limitations.

Advantages:

• Cost-Effectiveness & Affordability: This is a primary draw. Asphalt shingles are generally less expensive than most other roofing options, with affordable material and labor costs, making them an excellent option for budget-minded property owners in DFW.
• Design Versatility & Color Options: With hundreds of colors, textures, and styles available, an asphalt composition shingle roof offers incredible design flexibility. You can achieve a traditional look, a modern aesthetic, or even mimic more expensive materials like slate or wood shakes.
• Ease of Installation: Compared to other roofing materials, asphalt shingles are straightforward to install. This contributes to lower labor costs and quicker project completion times.
• Durability & Protection: Modern asphalt shingles are engineered to be durable, providing reliable protection against wind, rain, and extreme temperatures. Specialty options offer improved resistance to algae, hail, and fire (many achieving Class A fire ratings).

Disadvantages:

• Lifespan Limitations Compared to Premium Materials: While architectural and luxury asphalt shingles can last 30-50 years, this is generally less than premium metal, tile, or slate roofs, which can last 50-100 years or more.
• Wind Damage Susceptibility: This is a relevant consideration for DFW. Standard asphalt shingle roofs are often rated for winds up to 90 mph. In areas prone to severe storms like North Texas, this can mean a higher likelihood of damage. However, performance shingles and proper installation can significantly improve wind resistance.
• Heat Absorption (for darker colors): Darker asphalt shingles absorb more heat, which can lead to higher attic temperatures and cooling costs in our hot Texas summers. Lighter-colored or “cool roof” shingles can mitigate this by reflecting more sunlight.

An asphalt composition shingle roof offers a fantastic balance of performance, aesthetics, and value. For a broader look at various roofing options, check out our guide: More info about different roof types.

Factors Influencing the Lifespan of an asphalt composition shingle roof

When you invest in an asphalt composition shingle roof, you’re naturally wondering how long it will last. While manufacturer warranties range from 15 to 30 years, the actual lifespan can vary from 20 to 50 years. Several critical factors determine how long your roof will effectively protect your Dallas-Fort Worth home.

1. Shingle Quality and Type: Not all asphalt shingles are created equal.

   • 3-tab shingles typically last up to 25 years.
   • Architectural shingles generally provide around 30 years of service.
   • Luxury shingles can last over 30 years, potentially reaching 50 years under optimal conditions.

2. Climate and Weather Impact: This is a huge factor in DFW. Our Texas climate, with its intense UV rays, high winds, and hailstorms, can shorten a roof’s lifespan. Sudden temperature changes are also damaging. These stressors accelerate shingle aging, leading to granule loss, curling, and cracking. Choosing impact-resistant (Class 4) shingles is a smart decision for DFW homeowners.

3. Installation Quality: Even the highest-quality shingles won’t perform if not installed correctly. Proper installation, adhering to manufacturer guidelines and local building codes, is paramount. This includes correct nailing, proper underlayment, and meticulous flashing.

4. Attic Ventilation: Adequate attic ventilation is crucial for shingle longevity. A well-ventilated attic helps regulate temperatures, preventing heat buildup that can bake shingles from underneath and reducing moisture. Poor ventilation can lead to premature aging and may void manufacturer warranties.

5. Regular Maintenance and Inspections: Your roof benefits from routine check-ups. Regular inspections (ideally twice a year and after severe weather) allow us to catch minor issues before they become major problems. Proactive maintenance can significantly extend the life of your asphalt composition shingle roof.

Understanding these factors empowers you to make choices that maximize your roof’s lifespan. For more information on how to care for your roof, visit our page on More info about roof maintenance.

How an asphalt composition shingle roof Compares to Other Materials

When choosing a roofing material, the asphalt composition shingle roof is often the benchmark due to its popularity and affordability. However, it’s wise to compare it with other common options in terms of cost, durability, and aesthetics for your DFW property.

1. Cost Comparison:

   • Asphalt Shingles: The most affordable roofing material available, generally one-third to one-half the cost of other common composite shingles.
   • Metal Roofing: Higher upfront cost than asphalt shingles.
   • Tile Roofing: Clay or concrete tiles are considerably more expensive than asphalt.
   • Slate Roofing: One of the most expensive roofing materials.

2. Durability Comparison:

   • Asphalt Shingles: Good durability, with lifespans from 20-50 years. Standard options are susceptible to wind damage around 90 mph, but impact-resistant (Class 4) shingles offer superior hail protection.
   • Metal Roofing: Exceptional durability and longevity (40-70+ years), highly resistant to fire, wind, and impact.
   • Tile Roofing: Very durable and long-lasting (50+ years), but can be brittle and break on impact.
   • Slate Roofing: Virtually indestructible and can last 75-150+ years.

3. Aesthetics Comparison:

   • Asphalt Shingles: Immense versatility in color and style, able to mimic wood shakes, slate, or tile.
   • Metal Roofing: Available in various profiles and colors, offering a sleek, modern look or simulating traditional materials.
   • Tile Roofing: Provides a distinctive, often Mediterranean or Spanish-inspired aesthetic.
   • Slate Roofing: Offers a classic, high-end appearance with natural color and texture variations.

4. Maintenance Needs:

   • Asphalt Shingles: Low maintenance, requiring periodic inspections and prompt repair of any damage.
   • Metal Roofing: Very low maintenance.
   • Tile Roofing: Requires occasional cleaning and inspection for broken tiles.
   • Slate Roofing: Very low maintenance, though repairs require specialized skills.

Frequently Asked Questions about Composition Shingles

We get many questions from property owners in the Dallas-Fort Worth area about their roofing options. It’s normal to have questions when making a significant investment. Here are some of the most common inquiries we receive about asphalt composition shingle roof systems:

Are composition shingles and asphalt shingles the same thing?

Yes, absolutely! This is a common point of confusion. Composition shingles and asphalt shingles are the same thing. The term “composition” refers to the fact that these shingles are made from a “composite” of materials, typically a fiberglass mat, asphalt, and mineral granules.

You might hear insurance adjusters use “composition shingles” while contractors refer to “asphalt shingles.” Rest assured, they are both talking about the same reliable roofing product. So, next time someone asks, you can confidently say they’re one and the same!

How much does a new composition shingle roof cost?

The cost of a new asphalt composition shingle roof varies, so it’s hard to give a single number without seeing your property. However, asphalt shingles are widely recognized as the most affordable roofing option.

Several factors influence the overall cost:

• Type of Shingle: 3-tab shingles are the least expensive, followed by architectural shingles, and then luxury shingles, which can be double the price of architectural options.
• Roof Size and Complexity: A larger or more complex roof with multiple valleys, hips, and dormers will require more materials and labor, increasing the cost.
• Labor Rates: While asphalt shingles are generally the least expensive to install, regional labor costs can fluctuate.
• Additional Components: The cost includes the entire roofing system, such as underlayment, drip edge, flashing, and vents.
• Existing Roof Removal: Tearing off an existing roof, especially multiple layers, will add to labor and disposal costs.

As a general guideline, materials for an asphalt composition shingle roof can range from $0.80 to $1.20 per square foot. For a medium-pitch roof, the average shingle cost can be between $100 and $200 per “square” (100 square feet).

For precise pricing for your DFW home, we always recommend getting a professional estimate based on a thorough roof inspection.

Can you install new asphalt shingles over an old layer?

This is a common question from homeowners looking to save on costs. The answer is: sometimes, but with important caveats.

It is sometimes possible to install a new asphalt composition shingle roof over a single existing layer, provided the underlying roof deck is in good condition. This method can save money on tear-off labor and disposal fees.

However, there are critical considerations:

• Number of Layers: Most building codes, including those in DFW, limit shingle layers to two. If your roof already has two layers, a tear-off is mandatory.
• Roof Deck Condition: If existing shingles show significant damage or the roof deck feels soft, a full tear-off is essential. Installing new shingles over a problematic base will lead to premature failure.
• Warranty Implications: Some manufacturers have specific requirements regarding installation over existing shingles that could affect your warranty.
• Weight: A second layer of shingles adds significant weight to your roof structure.
• Aesthetics: Layering can sometimes create a less uniform appearance compared to a full tear-off.

For the best performance and longevity, and to allow for a thorough inspection of your roof decking, we generally recommend a full tear-off. Consulting with a qualified roofing professional is crucial to determine the best approach for your home.
