What is a Composition Roof? (3 Things to Know About a Composition Roof)

If you’re in the market for a new roof, you may have come across the term “composition roof.” But what exactly is a composition roof, and why is it such a popular choice among homeowners? Whether you’re considering a roof replacement or simply want to learn more about different roofing materials, this guide will cover everything you need to know about composition roofs.

What is a Composition Roof?

A composition roof is a roofing system made from a blend of materials, typically including asphalt, fiberglass, and sometimes recycled paper or other organic materials. This type of roofing is also commonly referred to as composite shingles or asphalt shingles, as it combines multiple components to create a durable, cost-effective, and versatile roofing solution.

Composition roofs come in a variety of styles, colors, and price points, making them one of the most popular roofing options in the United States.

Now, let’s dive into the three most important things you should know about composition roofs.

1. Types of Composition Roofing

Not all composition roofs are the same. There are three main types of composition shingles, each with its own benefits and drawbacks.

Three-Tab Asphalt Shingles

Three-tab shingles are the most basic and budget-friendly type of composition roofing. They are lightweight, uniform in appearance, and designed to last around 20 years.

Pros:

✔ Affordable option
✔ Easy to install
✔ Available in a variety of colors

Cons:

✘ Shorter lifespan compared to other roofing materials
✘ Less durable against high winds and extreme weather

Architectural Shingles (Dimensional Shingles)

Architectural shingles, also called dimensional shingles, are a step up from three-tab shingles. They are thicker, more durable, and have a multi-dimensional look that mimics the appearance of wood or slate roofing.

Pros:

✔ More durable than three-tab shingles
✔ Aesthetic appeal with a textured look
✔ Longer lifespan (25–30 years)

Cons:

✘ Higher cost than three-tab shingles
✘ Heavier, requiring proper roof support

Luxury or Designer Shingles

Luxury shingles are the highest-quality composition shingles available. They are designed to replicate the appearance of high-end materials like slate or cedar shakes while providing superior durability.

Pros:

✔ Long lifespan (30–50 years)
✔ High-end appearance
✔ Excellent resistance to extreme weather conditions

Cons:

✘ Most expensive option
✘ Heavier than other shingles, requiring additional structural support

2. Benefits of Choosing a Composition Roof

One of the reasons composition roofing is so popular is its wide range of benefits. If you’re trying to decide whether a composition roof is right for your home, here are some key advantages to consider:

Affordability

Composition shingles are one of the most cost-effective roofing materials available. They offer a great balance between price and performance, making them a popular choice for homeowners on a budget.

Versatility in Design

Composition shingles come in a variety of colors, textures, and styles, allowing you to customize the look of your home. Whether you prefer a classic or modern aesthetic, there’s a composition shingle option to match your taste.

Durability and Longevity

Depending on the type of composition shingle you choose, your roof can last anywhere from 20 to 50 years with proper maintenance. Architectural and luxury shingles offer increased durability against harsh weather conditions.

Ease of Installation and Repair

Composition shingles are relatively easy to install and replace, making them a convenient choice for both new roof installations and repairs.

Weather Resistance

High-quality composition shingles can withstand heavy rain, snow, wind, and even hail. Many manufacturers offer impact-resistant options that provide additional protection against severe weather.

Fire Resistance

Most composition shingles have a Class A fire rating, which is the highest level of fire resistance available. This can provide added peace of mind for homeowners concerned about fire safety.

Eco-Friendly Options

Many composition shingles are made with recycled materials and can be recycled at the end of their lifespan. If sustainability is important to you, there are eco-friendly composition roofing options to consider.

3. How to Maintain a Composition Roof for Longevity

Like any roofing system, a composition roof requires regular maintenance to maximize its lifespan and performance. Here are some essential maintenance tips:

Regular Inspections

Schedule a professional roof inspection at least once a year, especially after severe weather events. This will help identify and address any potential issues before they become major problems.

Keep Gutters Clean

Clogged gutters can cause water to back up under your shingles, leading to leaks and potential damage. Clean your gutters regularly to ensure proper drainage.

Remove Debris and Moss

Leaves, branches, and moss can trap moisture on your roof, which can lead to premature deterioration. Use a soft brush or gentle cleaning solution to remove debris without damaging your shingles.

Check for Loose or Missing Shingles

High winds and storms can cause shingles to become loose or fall off. If you notice missing or damaged shingles, replace them promptly to prevent further damage.

Ensure Proper Ventilation

Poor attic ventilation can cause heat and moisture buildup, which can shorten the lifespan of your shingles. Make sure your attic has adequate ventilation to regulate temperature and humidity levels.

Address Leaks Immediately

If you notice signs of a roof leak, such as water stains on your ceiling or walls, act quickly. Delaying repairs can lead to more extensive water damage and costly repairs.

When Should You Replace Your Composition Roof?

Even with proper maintenance, every roof eventually needs to be replaced. Here are some key signs that it’s time for a new composition roof:

• Age: If your roof is nearing the end of its expected lifespan, it may be time for a replacement.
• Frequent Repairs: If you find yourself constantly patching leaks or replacing shingles, a new roof may be a more cost-effective solution.
• Curling or Cracking Shingles: This indicates that your shingles are past their prime and no longer providing adequate protection.
• Granule Loss: If you notice excessive granules in your gutters, your shingles may be deteriorating.
• Moss or Algae Growth: While some growth can be cleaned, excessive moss or algae may indicate trapped moisture and potential damage.
• Sagging Roof: A sagging roof is a serious structural issue that requires immediate attention.

Final Thoughts

A composition roof is a versatile, affordable, and durable roofing option that can enhance your home’s curb appeal and protection. Whether you choose three-tab shingles, architectural shingles, or luxury shingles, a composition roof offers numerous benefits, including weather resistance, fire safety, and a wide range of design options.
