What Is an Asphalt Roof?

Popular as a roofing option in the United States, asphalt roofs are known for their affordability, durability, and ease of installation. The base material in these roofs is fiberglass or organic felt. This base material has another layer of asphalt and mineral granules coating it for color and UV protection.

Types of Asphalt Roofs

There are several types of asphalt shingles available, each with its own set of characteristics and benefits.

Three-Tab Shingles

Three-tab shingles are the most basic and economical option. They are named for the cutouts or tabs along their lower edge, which make each shingle appear as three separate pieces. These shingles are lightweight and easy to install, making them a good option for budget-conscious homeowners.

Architectural Shingles

Architectural shingles, also known as dimensional or laminate shingles, offer a more sophisticated look and better durability compared to three-tab shingles. They are thicker, with a layered construction that gives them a three-dimensional appearance. This type of shingle is more resistant to wind and can last longer, making it a good investment for homeowners looking for a balance of cost and performance.

Premium Shingles

Premium shingles represent the high end of asphalt roofing options. They come in various styles and colors, often designed to mimic the look of slate or cedar shakes. These shingles are heavier and more robust, offering superior durability and a distinctive aesthetic. While more expensive, they provide excellent longevity and can enhance your home’s curb appeal.

Average Cost of Asphalt Roof Replacement

Understanding the costs involved in replacing an asphalt roof can help you budget effectively. Here’s a detailed breakdown of what you can expect when planning for an asphalt roof replacement.

Factors Affecting the Cost of Replacing Your Roof

Size of the Roof

The size of your roof is one of the most significant factors influencing the cost of replacement. Larger roofs require more materials and labor, which increases the overall cost.

Type of Asphalt Shingles

The type of asphalt shingles you choose impacts the cost of replacing your roof due to differences in materials, durability, and aesthetics. Basic three-tab shingles are the most economical, costing less because they are thinner and have a simpler design.

Architectural shingles, which are thicker and have a more dimensional appearance, cost more because they offer better durability and aesthetic appeal. Premium shingles are the most expensive due to their superior materials and enhanced features, like improved weather resistance and longer lifespan. This choice affects both the initial installation cost and long-term maintenance expenses.

Labor and Installation Costs

Labor costs can vary significantly based on the complexity of the job, the roof’s pitch, and local market rates. On average, labor costs range from $150 to $300 per roofing square. Steep roofs, roofs with complex designs, or those that are more than one story high typically incur higher labor costs due to the increased safety precautions and difficulty of installation.

Using online cost estimation tools can provide a rough idea of what your roof replacement might cost based on your roof's size, the type of shingles you choose, and your location. These tools take into account various factors, such as labor rates in your area and the specifics of your home’s roof structure.

Financing Options

Additionally, you can explore home improvement loans or lines of credit to fund your roof replacement.
