When it comes to roofing materials, asphalt shingles are a popular choice for their affordability, durability, and versatility. However, the cost of installing a new asphalt roof can vary depending on a variety of factors. Understanding these factors can help homeowners make informed decisions and budget accordingly. In this post, we’ll explore the key factors that could influence the cost of a new asphalt roof.

1. Roof Size and Complexity

The size and intricacy of a roof are key factors influencing the cost of an asphalt shingle roof. Larger roofs necessitate more materials and labor for installation, driving up the total expense. Moreover, roofs with intricate designs, various angles, and additional features such as dormers or skylights may demand additional time and expertise for installation, thereby increasing labor costs.

2. Roof Pitch

The angle of the roof, known as the pitch or slope, can also affect installation expenses. Steeper roofs pose greater challenges, necessitating extra safety precautions, specialized equipment, and more labor for a secure installation. Consequently, roofs with steeper pitches generally entail higher installation costs than those with gentler slopes.

3. Choice of Asphalt Shingles

There are various types of asphalt shingles available on the market, ranging from basic three-tab shingles to high-end architectural shingles. The cost of the shingles themselves can vary significantly depending on their quality, durability, and aesthetic appeal. Homeowners can choose between different grades and styles of asphalt shingles based on their budget and preferences, with premium shingles generally commanding a higher price.

4. Underlayment and Decking

The state of the roof’s underlayment and decking can affect the total installation expenses. If the current underlayment or decking is in poor condition, it might require replacement before installing the new roof. Moreover, opting for superior underlayment materials, like synthetic or waterproof membranes, may raise the cost but offer increased roof protection and durability.

5. Labor Costs and Location

Labor costs vary depending on factors such as geographic location, local labor market conditions, and the experience level of the roofing contractor. In areas with higher living costs or greater demand for roofing services, labor rates may be higher, contributing to an overall increase in installation costs. It’s essential for homeowners to obtain multiple quotes from reputable contractors and consider factors beyond price, such as reputation and quality of workmanship.

6. Roofing Accessories and Add-Ons

Other roofing enhancements like ridge vents, flashing, and ice and water shields can influence the total expense of installing a fresh asphalt roof. These elements are vital for adequate ventilation, waterproofing, and shielding against weather conditions. Although they may increase the initial installation price, opting for high-quality accessories can improve the roof’s durability and effectiveness over time.


In conclusion, several factors can influence the cost of installing a new asphalt roof. From the size and complexity of the roof to the choice of shingles, underlayment, labor costs, and location, homeowners should consider various factors when budgeting for a roofing project. By understanding these factors and working with a reputable roofing contractor, homeowners can ensure a successful and cost-effective roof installation that provides lasting protection and peace of mind.
