While we would like to give you the average cost of replacing a residential roof, this statistic would not be particularly helpful. The cost is determined by a variety of factors.

Let’s look into the factors that are considered for roof replacement cost. We’ll tell you what professionals look at when bidding a job so that you know what to expect for your roofing project.

How to Determine Residential Roof Replacement Cost

How much should you expect to pay for a new roof for your home?

Here are the factors that are used to determine roofing costs.


Roof surfaces are measured in “squares.” A roofing square is equal to 100 square feet of the roof. So, for example, if a roof is 2,400 square feet, you would need at least 24 squares of shingles to cover the roof.

This is confusing to many homeowners who measure other items in their homes “per square foot.”

The take-home message is that your roof cost is determined by the cost of labor per square (and the cost of materials).


Another factor used to consider the price of a residential roof is the pitch. Most homes don’t have a flat roof, so the pitch (or the roof’s incline) is also another essential factor in determining costs.

Roofing Materials

Residential roof replacement cost also depends on the roofing material used for the project.

Asphalt shingles are typically on the lower end of material costs. Other roof materials, such as a cedar shake roof, cost more. In addition, a metal roof typically costs more to replace, as does concrete tile, clay tiles, or copper roofing.

If you have an asphalt roof and a smaller or average-sized home, you may think that replacing your existing roof with new asphalt shingles should be on the low end of the price spectrum. However, there are still other factors to consider.


How many layers of shingles are on your asphalt roof? Your reroofing costs will be determined by whether the old roof shingles are removed (meaning the entire roof is replaced.)

Some code requirements only allow two layers of shingles. If you have two or more layers, most roofing contractors require you to purchase a new asphalt shingle roof. In addition, removing old shingles means more labor costs and waste removal costs.

Your Location

Some areas of the country are more expensive than others regarding roofing labor cost and the price of materials.
