Let’s get started!
Understanding the Key Factors That Affect the Cost of Your Roof Replacement
Many factors impact the cost of your roof replacement, such as the type of underlayment, the location of the job, and the time of year. However, in our 30 years of experience, we've found that there are three main factors needed to get an average cost for a roof replacement.
- The type of materials
- The square footage of the roof
- The slope of the roof
Let us review each of these 3 factors that'll impact the cost first. Then we'll cover how to put them all together.
Reflecting on Current Roofing Trends and Material Costs
The type of materials you choose for your roof replacement can have a significant impact on the cost of the project. Some materials are more expensive than others, but they may also offer greater durability or a longer lifespan.
Additionally, some materials may need skilled installers or specialized equipment to install. This can also add to the cost of the project. Understanding the pros and cons of different roofing materials can help you choose the right one for your budget and needs.

These are some of the most popular material options. Now let's discuss how to measure your roof's square footage to get an accurate roofing materials cost comparison.
Accurate Measurement Techniques for Modern Roofs
Accurately measuring your roof's square footage is a critical part of calculating the cost of your roof replacement. Here's how to get an accurate measurement:
First, measure the length and width of each plane of the roof, including any dormers or other protrusions. Then, measure the length of each plane. Next, multiply the length by the width of each plane to get the square footage of each section of the roof.
To calculate the total square footage of the roof, add up the square footage of each plane.
However, it's important to note that not all square footage measurements are created equal. A roof with more angles (hips & valleys) will have more cuts and thus use more waste.
The waste factor refers to the number of excess materials that will be needed due to the cuts and waste that occur during the installation process. This can vary depending on the complexity of the roof, such as its slope and the number of valleys, hips, and ridges. The more waste, the more materials are needed to complete the project. Which will result in a higher cost for the materials.
Roofing contractors typically estimate the cost of a roof replacement based on the square footage of the roof. But keep in mind they take into account additional factors needed for your roof replacement. Such as waste factor and extra labor cost for roofs with greater slopes which were going to be discussed in the next section.
Navigating Roof Slope and Complexity in Today’s Designs
The slope or complexity of a roof can significantly impact the installation cost. A roof with a steeper pitch will take more labor. A complex roof design may also need additional installation steps, which can further increase the labor cost.
Besides the direct costs of materials and labor. There are more costs associated with complex steep-slope roofs. The new modern architectural designs of homes will affect the cost of a roof replacement.
Scaffolding and specialty equipment may be needed to ensure the safety of the workers. These extra costs are important to consider when calculating the total cost of the project.
All these factors impact the cost of the project because they require more time, materials, and labor to complete. Roofing contractors must account for these extra costs when estimating the project's total cost. So, it's important to accurately measure the roof and factor in the complexity when creating your roof budget.
Putting It All Together: How to Calculate Your Roofing Cost
Calculating the cost of your new roof can seem like a daunting task, but it doesn't have to be. By understanding the three main factors - the type of materials, square footage, and slope - you can accurately estimate the cost of your project.
Here is a step-by-step guide to calculating the cost of your new roof:
- Determine the square footage of your roof by measuring the length and width of each section and then add them together.
- Determine the slope or complexity of your roof by visually inspecting it or consulting with a professional roofing contractor.
- Choose the type of materials you want for your new roof and estimate the cost per square foot based on your selection.
- Multiply the square footage by the cost per square foot of your selected material.
- Add any extra costs associated with the slope or complexity of your roof. Such as safety equipment, scaffolding, and extra labor.
To give you an idea of what to expect, let's take a look at two examples:
For a simple roof with asphalt shingles, the cost per square foot can range from $4 to $6 per square foot. With a square footage of 1,500, the total cost would be between $6,000 and $9,000.
For a complex roof installing standing seam metal, the cost per square foot can range from $12 to $19. With a square footage of 2,500, the total cost would be between $30,000 and $47,500.
