How much does roof replacement cost in the USA?

Roof replacement is not an easy task to undertake, especially for homeowners. There are a lot of elements you must take into account to get the best results. From the materials to the type of roof, there are countless factors that you have to consider before making a final decision.

In some cases, a complete removal and replacement might be necessary; in others, an extension or a re-covering may suffice. If your roof has visible damage, is getting old (roofs with less than 10 years of remaining shelf-life are considered too old for solar panels) or you just want to give your home a fresh look, you should replace your roof. Make sure to do so with proper precautions and meticulous planning so that you can save money in the long run.

You'll need to factor in several expenses, such as hiring professionals, purchasing supplies, and removing old materials. Read on to learn more about how much a roof replacement will cost you.

8 Key Factors Affecting Roof Replacement Costs

The cost of a roof replacement is determined by various factors some of which the homeowner has no control over, such as geographical location, weather, and roof size. However, some components can significantly affect the overall cost and are within the homeowner's control, such as the type of materials used.

Size of Roof

The size of your roof is the first factor that will affect the cost of roof replacement because roofing materials are generally sold in units of roofing squares. To calculate this number, the roofer will take the square footage of your roof and divide it by 100 square feet. Keep in mind that the larger your roof, the more expensive it will be to replace.

Location of Your Home

The location of your home affects the cost of replacing your roof. You’ll have to select the appropriate type of shingles or roofing that will best withstand the climate and comply with local building codes, and HOA rules. These are just some examples of how your location plays a role in the price of a new roof. Another aspect that is crucial in the cost of replacing your roof is the height of your home as higher homes will take longer to replace and thus will require more labor.


Roof Access

If your roof is difficult to access, it will take more time and effort to remove the old roof and install the new one. For experienced roofers, the easier the access and the less time needed to complete the job, the cheaper the cost of the roof replacement project.

Roof Materials

Typical roofing materials account for around 40% of your total roof replacement costs, anywhere from $100 to $1000 per square (100 square feet). However, this can vary depending on the roof you have installed. Choosing a more unique or specialized roofing option will likely require more costly materials.

Roof Pitches

The roof pitch is the steepness or angle of your roof, which is calculated by a method in which you determine the number of inches your roof rises vertically for every 12-inches it extends horizontally. For example, a roof that rises 5 inches vertically for every 12 inches horizontally has a 5-in-12 pitch. The size of your roof pitch will impact the time and labor needed to replace your roof and, therefore, the cost.


When you get a roof replacement estimate from a roofing contractor, about 60% of that estimate accounts for the roofing labor cost per square foot, and the other 40% covers the cost of materials. The average roofing labor cost is $1.50 to $3.00 per square foot. One roofing square covers 100 square feet. So if you get a labor quote of $1.50 to $3.00 per square, it will cost $1.50 to $3.00 per 100 square feet to replace the roof.

Roof Repair Permits

The cost of your roof repair project can be influenced by whether or not your city or town requires permits for such work. In places where permits are required, the fee typically depends on either one flat rate, the size of your roof, and the amount of work to be done.


If you want to utilize a sustainable roofing solution, consider investing in roof coating. Roof coating reduces energy bills and provides UV and water resistance, extending the roofing system's lifespan. Similarly, other roofing add-ons, such as installing solar roofs or going green, may significantly reduce your energy bills but will need an initial investment.
