If you’re planning to install shingles on your roof, one of the first questions that might come to mind is, “How much will it cost?” Understanding the cost of shingle installation per square can help you budget for your roofing project effectively. In this blog, we’ll break down the factors that influence this cost and provide you with a clear picture of what to expect.


Shingles are a popular roofing material due to their durability, versatility, and affordability. The cost of installing shingles per square, which covers a 100-square-foot area, can vary based on several key factors. Let’s delve into these factors and see how they impact the overall cost.

Factors Influencing Shingle Installation Costs

1. Shingle Type

The type of shingles you choose significantly affects the cost. Three-tab asphalt shingles are the most budget-friendly option, while architectural or dimensional shingles tend to be a bit pricier but offer enhanced aesthetics and durability.

2. Roof Size

The size of your roof directly correlates with the total cost. Larger roofs require more materials and labor, increasing the overall expense.

3. Roof Complexity

Roofs with complex designs, multiple angles, and intricate features like dormers or skylights may require more time and effort for installation, driving up costs.

4. Tear-off or Overlay

If you’re installing new shingles over an existing roof (overlay), it might be cheaper than a complete tear-off, where the old roofing is removed entirely. However, some local building codes may not permit more than one layer of roofing.

5. Underlayment and Ventilation

Proper underlayment and ventilation are crucial for a long-lasting roof. Investing in high-quality materials for these components can add to the cost but provide better protection and energy efficiency.

6. Location

Labor and material costs can vary by location. Urban areas often have higher labor rates and material costs compared to rural areas.

7. Labor Costs

Labor costs vary based on your location and the roofing company you hire. Experienced and reputable contractors may charge more for their services.


So, how much does it cost to install shingles per square? On average, you can expect to pay anywhere from $100 to $200 per square for three-tab asphalt shingles, while architectural shingles may range from $200 to $400 per square. Keep in mind that these are approximate figures, and the final cost of your roofing project will depend on the factors mentioned above.
