Understanding the Cost of a New Roof: An In-Depth Guide by Ragan Roofing

Investing in a new roof is a substantial decision for any homeowner or property manager. With more than two decades of experience serving the Nashville, TN, community, Ragan Roofing is here to provide a comprehensive breakdown of what goes into the cost of a new roof.

The Basics: Materials, Labor, and Size

Every roof is unique, just like the buildings they protect. The three primary components influencing the cost of a new roof are materials, labor, and the roof size.


Materials will account for a significant portion of your new roof cost. Choices vary, including asphalt shingles, metal, slate, and tile. Asphalt shingles are a popular option for their balance of cost and durability, while metal roofing offers longevity and a modern look. Slate and tile roofs deliver a high-end appearance but have a higher price tag due to their premium materials and installation complexity.


The labor cost for a new roof primarily depends on the complexity of the top and the expertise required for installation. Expect to pay more for high-pitched roofs, multiple layers, or roofs with chimneys and skylights.


Roofing prices are often quoted per square (a “square” in roofing terms is 100 square feet). Therefore, larger roofs will inevitably cost more.

Underlayment and Flashing:

Underlayment and flashing are critical components of a successful roofing system. They help prevent water intrusion and protect the overall integrity of your home.


The underlayment is a protective layer between the roof deck and the roofing materials. It serves as a secondary barrier against severe weather.


Flashing is installed around chimneys, skylights, and vents to direct water away from these vulnerable areas. Proper installation is critical to prevent leaks and ensure longevity.

Roof Design and Complexity:

Roof design plays a considerable role in determining the cost of a new roof. Complex roofs require more materials and labor.

Pitch and Slope

High-pitched roofs are more challenging and dangerous to work on, increasing labor costs.

Architectural Features

Architectural features like chimneys, skylights, and dormer windows add complexity, requiring additional time and materials to integrate into the roofing system properly.

Removing the Old Roof:

The cost of removing and disposing of the old roof can also impact the overall cost. This includes the labor of tearing off the old materials and the disposal fees.

Additional Factors:

Other factors like permits, warranties, and the local cost of living can also influence the final roofing cost.
