Asphalt Shingle Tiles

Asphalt shingle tiles are a staple in the roofing industry, prized for their affordability, versatility, and ease of installation. They are by far the most commonly used roofing material in North America, and their popularity extends globally due to their balance of cost-effectiveness and durability. This comprehensive guide will delve into the intricacies of asphalt shingle tiles, covering everything from their composition and types to installation techniques, maintenance tips, and considerations for choosing the right shingles for your specific needs. Whether you’re a homeowner considering a roof replacement, a contractor seeking to expand your knowledge, or simply curious about the material that protects your home, this article aims to provide valuable insights.

What are Asphalt Shingle Tiles?

At their core, asphalt shingles are composed of a base material, usually fiberglass or organic felt, saturated with asphalt and coated with mineral granules. The asphalt provides waterproofing, while the granules protect the asphalt from ultraviolet (UV) degradation and add color. The base material provides structural support and contributes to the shingle’s overall strength.

Composition Breakdown

Let’s break down the components of asphalt shingles in more detail:

Base Material: This is the foundation of the shingle. Fiberglass mats are the most common base material today, offering superior fire resistance and dimensional stability compared to the older organic felt mats. Organic felt mats are made from recycled paper products.
Asphalt: The asphalt is a petroleum-based product that provides the waterproof barrier. Different types of asphalt are used, with modifications to improve flexibility and durability.
Mineral Granules: These small, colored particles are embedded in the asphalt surface. They protect the asphalt from the sun’s harmful UV rays, which can cause it to dry out and crack. The granules also add aesthetic appeal to the roof.
Sealant: Many asphalt shingles have a sealant strip that is activated by the sun’s heat. This sealant bonds the shingles together, creating a wind-resistant and watertight seal.

A Brief History

Asphalt shingles have evolved significantly over the years. Early versions were made from organic felt soaked in asphalt, offering a relatively inexpensive roofing solution. However, these organic shingles were prone to moisture absorption and had a shorter lifespan. The introduction of fiberglass mats revolutionized the industry, providing a more durable and fire-resistant alternative. Modern asphalt shingles incorporate advanced technologies and materials to enhance performance and longevity.

Types of Asphalt Shingle Tiles

Asphalt shingles are available in various types, each offering different features and benefits. The primary types include:

3-Tab Shingles: These are the most basic and economical type of asphalt shingle. They are characterized by their uniform shape and flat appearance, giving the roof a consistent, linear look.
Architectural Shingles (Dimensional Shingles): Also known as laminated or dimensional shingles, these are constructed with multiple layers of material, creating a thicker, more textured appearance. They are more durable and visually appealing than 3-tab shingles.
Luxury Shingles: These are the premium option, designed to mimic the look of natural slate or wood shakes. They offer exceptional durability and aesthetic appeal, but come at a higher price point.

3-Tab Shingles: The Economy Option

3-tab shingles are a budget-friendly choice for homeowners looking for a basic roofing solution. They are typically less expensive than architectural shingles and easier to install. However, they have a shorter lifespan and offer less wind resistance. The “3-tab” name comes from the cutouts that create three distinct tabs on each shingle.

Pros:

Affordable
Easy to install
Lightweight

Cons:

Shorter lifespan
Lower wind resistance
Less visually appealing than other options

Architectural Shingles: Balancing Cost and Performance

Architectural shingles are the most popular choice for homeowners seeking a balance between cost and performance. They offer a longer lifespan, better wind resistance, and a more visually appealing appearance than 3-tab shingles. The layered construction creates a three-dimensional effect, adding depth and texture to the roof.

Pros:

Longer lifespan than 3-tab shingles
Better wind resistance
More visually appealing
Increased home value

Cons:

More expensive than 3-tab shingles
Slightly more complex installation

Luxury Shingles: The Premium Choice

Luxury shingles are the top-of-the-line option, designed to replicate the look of natural slate or wood shakes. They offer exceptional durability, wind resistance, and aesthetic appeal. These shingles are often thicker and heavier than other types, providing superior protection against the elements. While they are the most expensive option, they can significantly enhance the curb appeal and value of your home.

Pros:

Exceptional durability
Superior wind resistance
Highest aesthetic appeal
Significant increase in home value

Cons:

Most expensive option
Requires professional installation
Heavier than other shingle types

Factors to Consider When Choosing Asphalt Shingles

Selecting the right asphalt shingles for your home involves considering several factors, including:

Budget: Determine how much you are willing to spend on your new roof. 3-tab shingles are the most affordable, while luxury shingles are the most expensive.
Climate: Consider the climate in your area. If you live in an area with high winds or frequent storms, choose shingles with a high wind resistance rating.
Roof Pitch: The pitch of your roof can affect the type of shingles you can use. Some shingles are not suitable for low-slope roofs.
Aesthetic Preferences: Choose shingles that complement the style and color of your home.
Warranty: Look for shingles with a comprehensive warranty that covers defects and premature failure.

Understanding Wind Resistance Ratings

Wind resistance is a crucial factor to consider, especially if you live in an area prone to high winds. Shingles are tested and rated for their ability to withstand wind speeds. Look for shingles with a wind resistance rating of at least 110 mph for most areas. In areas with particularly strong winds, consider shingles with a rating of 130 mph or higher.

Evaluating Fire Resistance

Fire resistance is another important consideration. Asphalt shingles are classified according to their fire resistance. Class A is the highest rating, offering the best protection against fire. Class C is the lowest rating. Fiberglass-based shingles typically have a Class A fire rating, while organic shingles may have a lower rating.

Considering Color and Style

The color and style of your shingles can significantly impact the appearance of your home. Choose a color that complements your home’s exterior and landscaping. Consider the architectural style of your home when selecting a shingle style. For example, a traditional home might look best with architectural shingles that mimic the look of wood shakes, while a modern home might benefit from the clean lines of 3-tab shingles.

Asphalt Shingle Installation: A Step-by-Step Guide

Proper installation is crucial to ensuring the longevity and performance of your asphalt shingle roof. While it is recommended to hire a professional roofing contractor for installation, understanding the basic steps involved can help you make informed decisions and monitor the quality of the work.

Step 1: Removing the Old Roofing

The first step is to remove the existing roofing material down to the roof deck. This involves carefully prying up the old shingles and removing all nails and staples. Inspect the roof deck for any signs of damage, such as rot or decay. Replace any damaged sections of the roof deck before proceeding.

Step 2: Installing Underlayment

Underlayment is a waterproof barrier that protects the roof deck from moisture. It is typically made of asphalt-saturated felt or synthetic materials. Roll out the underlayment over the entire roof deck, overlapping each course by at least 2 inches. Secure the underlayment to the roof deck with nails or staples.

Step 3: Installing Drip Edge

Drip edge is a metal flashing that is installed along the edges of the roof to prevent water from running behind the fascia boards. Install the drip edge along the eaves and rakes of the roof, overlapping each piece by a few inches. Secure the drip edge with nails.

Step 4: Installing Starter Course

The starter course is a row of shingles that is installed along the eaves of the roof. It provides a solid base for the first course of shingles and helps to prevent water from seeping under the shingles. Use a special starter shingle or cut tabs off of regular shingles to create a starter course.

Step 5: Installing the First Course of Shingles

Begin installing the first course of shingles at the bottom left corner of the roof. Align the bottom edge of the shingles with the starter course. Secure the shingles to the roof deck with nails, following the manufacturer’s instructions for nail placement.

Step 6: Installing Subsequent Courses of Shingles

Continue installing subsequent courses of shingles, overlapping each course by the specified amount. Stagger the seams between the shingles to prevent water from seeping through. Use a chalk line to ensure that each course is straight and aligned.

Step 7: Installing Ridge Cap

Ridge cap shingles are installed along the ridge of the roof to provide a watertight seal. Cut individual shingles into smaller pieces to create the ridge cap. Overlap each piece by several inches and secure them with nails.

Step 8: Cleaning Up

Once the installation is complete, clean up any debris and leftover materials. Dispose of the old shingles and packaging properly. Inspect the roof for any missed nails or damaged shingles.

Maintaining Your Asphalt Shingle Roof

Curling or Buckling Shingles: Curling or buckling shingles indicate that the shingles are drying out and losing their flexibility.
Granule Loss: Excessive granule loss can expose the asphalt to UV rays, causing it to degrade and crack.
Water Stains on Ceilings: Water stains on ceilings are a sign of a roof leak.
Sagging Roof Deck: A sagging roof deck indicates that the roof is structurally compromised and needs immediate repair.

The Importance of Professional Inspections

While regular visual inspections can help you identify obvious problems, it’s important to have your roof professionally inspected every few years. A professional roofing contractor can identify hidden problems that you may not be able to see, such as damaged flashing or hidden leaks. They can also provide recommendations for maintenance and repairs.

Asphalt Shingle Roof Replacement: When is it Time?

Even with proper maintenance, asphalt shingle roofs eventually need to be replaced. The lifespan of an asphalt shingle roof depends on several factors, including the type of shingles, the climate, and the quality of the installation. However, most asphalt shingle roofs last between 15 and 30 years.
