How Much Does A Roof Replacement Cost?

Aerial View

Roof maintenance is one of the most important parts of owning a home. Homeowners from Beaverton to West Linn need to pay particularly close attention because our homes are constantly exposed to a variety of natural elements that can wear on a roof. Unfortunately, many people ignore the state of their roof until it’s too late. Their only option becomes a complete roof replacement.

To figure out what a roof replacement costs, you have to talk to the specific contractor you want to work with. There is no industry standard that you can expect like other types of projects. But depending on the size of the roof and what type of roofing material is used, homeowners have typically paid between $5,400 to $11,700 for a full roof replacement.

Because every roof is unique and every roofing company is unique, you will see a wide range of price estimates. You might even see a range of names for the parts and processes used to replace your roof. It can be very confusing.

The best thing to do if you want to figure out how much it will cost to replace your roof is to find a contractor you trust to give you an estimate. Ask as many questions as you need to understand the entire process.

How Can You Estimate the Cost of a New Roof?

If you want a basic estimate of how much it would cost to replace your roof, the most basic calculation is to figure out the average cost per square foot of the material you want to be installed on your roof and multiply it by the square footage of your home.

It would look something like this:

Sq. Ft. Cost of Material x Sq. Ft. of Home = Basic Estimate

Of course, the contractor you work with will likely offer you a different price, but this will at least put you in the right ballpark. Want some more detail? We’ll show you.

Cost to Replace a Roof on a 1,500 Square Foot House?

Let’s say you want to completely replace your existing roof with a cedar shake roof. We’ll assume the cost of cedar shake is $12.80 per square foot and your home is 1,500 square feet.

For that, the calculation would be:

$12.80 x 1500 = $19,200

These figures include labor for Roof Life of Oregon. However, some roofing contractors may provide estimates that don’t initially account for removing your existing roof material, the shape of your roof, or the labor costs.

Cost to Replace a Roof on a 2,500 Square Foot House?

Now, let’s say you want to go with a more cost-effective choice. You love the look of asphalt roofs and you want to replace your current roof with asphalt shingles.

Let’s assume that the cost of materials is $6.80 per square foot and your home is 2,500 square feet.

The calculation would be:

$6.80 x 2500 = $17,000

Again, that is a basic estimate including labor for Roof Life of Oregon. But you can see how the size of your home doesn’t automatically mean you will pay more.

The easiest way to know what your options are, and what your roof replacement will cost, is to give us a call or schedule your roof estimate. We will give you exact pricing and deliver extraordinary value.

How Does Roof Life of Oregon Calculate the Cost of A New Roof?

What Factors Affect the Cost of A New Roof?

Although there is no industry standard for customer care or roof replacement costs, there are a few factors that every contractor will include in their price.


The biggest portion of the total roof replacement cost is labor.

Contractors will typically pay employees by the hour or by the size of the roof. Companies that pay by square foot typically finish the job faster but the quality can be compromised.

When employees are paid by the hour, they are usually motivated to do the best job they can. They know that they have the time they need to do the job right and deliver a high-quality experience that customers will love.

Feel free to ask your contractor how the labor is calculated. A trustworthy company will be confident in their price as well as the roof replacement they deliver.


Next, the contractor will consider the materials used to replace your roof. A quality contractor will ensure that the material and your roof meet manufacturer requirements so that you can take full advantage of your warranty.

Most common materials that will be used when replacing a roof:

  • Underlayment
    • A waterproof barrier applied to your roof under your shingles
  • Shingles
    • The material that covers your roof and is seen from the outside
  • Drip Edge & Flashings
    • Installed to direct the flow of water to gutters and keep water from entering your home

Roof Life of Oregon is unique because we offer a lifetime workmanship warranty that aligns with the manufacturer. If anything happens to your roof for after we install it, we will come back and fix any damage, free of charge.

Does the Size of A House Affect the Cost of a New Roof?

The cost of your roof replacement also includes the size of your roof. The more square footage you need to replace, the higher your price will be.

Typically, when you receive your estimate, the price will be broken down by square foot.

One last detail to remember — if your roof has steep slopes, your roof replacement will likely be more expensive. The height of your pitch and the slope of your roof affect the necessary equipment and the safety of the employees. Although this isn’t usually a significant change, it is one to prepare for if your roof is steep.

By now, you might be thinking there are too many variables to consider to figure out what it would cost to do a roof replacement on your house. We get it. We’ve worked for years to get good at this!
