3 Things That Will Influence the Cost of Replacing Your Roof

When you realize that you need to replace the roof of your home, you might feel concerned about the cost of this project. This is especially true if you've often heard family members or friends talk about how expensive this job can be. While it's true that roof replacement can be pricey, it's also an important investment in your home. You should also know that there are many different factors that influence the cost of the roof, which means that you may not be looking at as pricey a job as you think.

Here are three things that will play a role in how much your roof replacement costs.

Square Footage

One of the biggest factors that will influence the cost of your roof is the square footage. The larger your roof, the more shingles that it will require — and the more time that your local roofing contractor will need to do the work. Fortunately, the opposite is also true. If you have a smaller roof, which may be the case with a two- or even a three-story home, you may not be looking at as much of an expense as you might be thinking. This is one perk of living in a two-level home compared to a bungalow. Generally, the roof is smaller in the former type of residence, which results in less of an expense when it comes time to replace the roof.

Number of Dormers

Some residential roofs have multiple dormers throughout them, which can add visual appeal and functionality to the home. If your roof has dormers, you can expect that your roofing job will cost more. This is because there is more labor involved. The dormers present a challenge for the roofing crew, as well as necessitate the use of more materials. Consider the appearance of your roof. If your roof doesn't have dormers and has a straightforward look, this is another thing that will bring the replacement cost down.


Many roofing contractors will consider the slope of your roof when they're giving you a quote to replace it. Residential roofs can vary considerably in their slopes, and those that are more sloped will often cost more money to replace. This is because working on a sloped roof is more challenging. Whereas roofers can walk around with ease on a roof that has a minimal slope, this isn't the case on a steeper one. A steeper roof is thus slower to work on, which can make it cost more money.
