Roof Replacement Cost: New Roof Cost Breakdown

Thinking about roof replacement cost breakdown might not be your favorite pastime, but it’s crucial to understand what is involved in getting a new roof. Let’s delve into the average cost of roof replacement, broken down by material type, so you’re well-prepared for what lies ahead.

The average cost of replacing a roof in the US is anywhere from $6,300 to $16,200 for basic tear-off and installation. You can expect to pay up to $30,000 or more for larger homes or complex roof configurations.

Some homeowners insurance policies may cover roof damage under certain conditions.

When planning for a roof replacement, knowing the national average cost is helpful to set your expectations and budget accordingly. Understanding the roof cost is essential for homeowners planning a roofing project.

Remember, the extra cost of a new roof can fluctuate based on your location and the size and pitch of your roof. So, when you’re ready to replace your roof, it’s wise to contact a professional roofing contractor in your local area.

When considering a new roof, consulting with professional roofing companies can provide a detailed breakdown of expenses.

Drawing from my experience of inspecting thousands of roofs, here’s what you need to know:

How to Measure for Roof Replacement Cost

Roof surfaces are measured in ‘squares.’ A roofing square equals a 10′ x 10′ area or 100 square feet. Roofing contractors typically charge between $350 and $900 per square for basic re-roofing.

The roof replacement cost can vary significantly depending on the size of your home and roof. Roofs come in all shapes and sizes. As a rule of thumb, you can estimate your roof size to be 1.5 times the square footage of your home.

So, let’s say your house is 1500 SF. In that case, your roof surface would be approximately 2,250 square feet or 22.5 square.

A professional roofing contractor will accurately measure the roof area. Many roofing estimators use drones or aerial footage to scan and measure the roof surface for safety reasons. Be aware that most roofing quotes only cover replacement shingles, flashing, and underlayment and don’t include new roof decking or roof structure repairs.

As you might expect, a more complex roof design will cost more.

How to Estimate the Cost of a New Roof?

As we have stated in our estimates in the introduction, the low and high ranges for roof replacement seem miles apart. It can be attributed to the various factors that come into play when determining a quote. It isn’t as simple as buying a specific number of shingles or taking a measurement. 

So, what drives the cost of a new roof? The average roof replacement cost can vary widely depending on materials and labor. Proper roof installation is crucial for the longevity and performance of your new roof.

Here are the factors you have to consider when estimating the cost of a new roof:

Material Costs

Shingles come to our minds when we think of what is used to make a roof. 

However, we aren’t unaware that a new roof requires additional materials. The materials include ridge vents, flashing, ice & water shield, underlayment, and plywood. You should include all these features in the warranty and project quote. 

And even though asphalt shingles form the most popular roofing materials in the United States, you still have several options. If you go for metal, tile, wood, or any other material, your price could go down or up.

Installation and Labor Costs

Installing roofs is a dangerous and challenging task. The construction industry suffers from a shortage of roofing professionals and skilled workers willing to fix roofs. 

A study commissioned by The Roofing Alliance concluded that 90% of United States roofing contractors encountered labor shortages last year. There is no argument that this is set to raise the prices.

Roof Pitch

The pitch of the roof represents its incline or slope. It represents the number of inches the roof rises vertically for each horizontal foot. For instance, a roof that increases six feet for each horizontal foot has a 4:12 pitch. 

As per the Omni Calculator, there are at least four different types of roof pitches: 

  • Flat roofs: The roofs have a pitch range of ½:12 to 2:12, which translates to 4.2% to 16.7%. The roofs are cheaper since they are easier and safer to install.
  • Low-pitched roofs: They have a pitch of 4:12, which translates to 33.3%. They are still walkable and cost more than flat roofs. 
  • Conventional roofs: These roofs have a pitch range of 4:12 to 9:12, translating from 33.3% to 75%. The roofs are safer to walk on. They are also easier to construct. 
  • High-pitched roofs: These roofs have a pitch of 21:12, which translates to 175%. The roofs are expensive due to added precautions and equipment. Roofs with steep pitches require additional safety measures, which can affect the overall cost.

A steep roof draws more charges due to added safety measures such as harnesses that you should wear. It also slows the installation process since they aren’t walkable. 

Roof Height

Even if you develop a roof with a walkable pitch, its height from the ground influences its overall costs. The higher the roof, the more the cost since complex equipment is required for installation. 

For instance, installation tasks require you to have a 40’ or 50’ ladder for installation purposes. The installation personnel will also demand more pay for added installation difficulties and danger. 

A roof is considered high if it has its gutter line at least 15 feet from the ground. 

Unknown Roof Structure Repair Costs

You won’t know what you’re going into buying and replacing a new roof until the project starts. You’ll know and feel the costs after you have peeled off the old roof in most cases. 

The roof deck is the foundational layer over which all other roofing materials are laid. If the wood you used rot due to moisture exposure, you should replace it. It’ll, therefore, automatically drive the cost of replacement up. 

Roof Layers

A critical step in roof replacement and repair is the removal of old layers. This involves an inspection of the decking for any rot or water damage before installing the new roof.

Removing a roof with many added layers requires more labor, increasing the overall labor costs. The additional weight from the layers will also increase the cost of disposing of and removing shingles, especially if you use a commercial dumpster on your job site. 

However, we discourage you from installing a new roof over old layers to save costs. Always ensure that all layers are removed before you install a new roof. 

If you overlay a roof, it will reduce the new roof’s life by about 50% and, at the same time, negate the manufacturer’s warranty. Most reputable contractors don’t do overlays. 

What Is The Price Of A New Roof In My Area?

The roofing materials available on the market cost $100 – $1,000 per square, for a roof with an average size of 17 squares, roofing material costs typically between $2,500 to $25,000.

MaterialCost for 17 squares
Stainless steel$14,000
Galvanized steel$3,000
3-tab asphalt shingles$2,500

However, you should know that most projects’ breakdown is 60% labor and 40% products. The roofing cost guide contains more about the available options and their prices, pros, and cons. 

Labor Cost Per Square Feet 

The labor cost for roof-related tasks ranges between $1.50 to $3 per square foot. However, the price depends on the condition of the structure and the product you’re installing. 

As mentioned above, overhead and labor comprise 60% of the project. For instance, if your project costs $100,000, at least $60,000 will go to overhead and labor. 

A roofing square is made up of one hundred square feet. The rate per square involves all relevant factors: 

  • Labor
  • Supplies
  • Available protective elements
  • Waste removal
  • The price of shingles

Understanding the Average Roof Replacement Cost

The average roof replacement cost can vary widely depending on factors such as geographic location, type of roof material, and the size of your roof. A larger roof will require more materials and labor, impacting the total cost.

Cost To Replace And Tear Off Roof

You will incur about $1 to $5 to remove an old roof per square foot. A complete job for most roofs will cost between $1,000 to $1,500. Some contractors prefer hourly charges, ranging between $40 to $80 each hour. 

If your roof has rooting timber or requires extra support for heavier material, there is an additional $1,000 – $10,000 that you must pay. However, the actual value depends on the type of reinforcement and repair you require. 

However, the rate you’ll be charged will fluctuate depending on the workload, location, material, and complexity. Removing old shingles is the most challenging task, whether you’re doing the work yourself or as a contractor. 

However, pros usually do the work efficiently and safely. You can explore more about shingle removal tips to understand more.

How Long Do Residential Roofs Last?

The materials used in making the roof determine its lifespan. The cost of a new roof also depends on what it is made of. That’s why it’s crucial to select your roof carefully. 

Here are some of the most common roof materials used in the US:

MaterialCost per Sq.Ft. (Labor Included)Cost for a 2,000 Sq.Ft. Roof

Asphalt Shingles

Basic asphalt shingles are a popular and affordable option for many homeowners. Among the various materials, asphalt shingles remain an affordable option for many.

Most homes in the United States have an asphalt shingle roof. There are two types:

  • Three-tab shingles: These roof types are designed with three 12”-wide tabs. They are rated to operate in 60 mph winds and have a lifespan of 25 years
  • Dimensional or Architectural shingles: These have a 30 to 50 years lifespan. They are designed for 110 mph winds. They have a dimensional and contoured style that emulates the look of wood shakes. 

These roofs are easy to repair, fairly inexpensive, and aesthetically pleasing. However, they can be damaged by hail. 

Their average cost is between $6,000 to $12,000.

Basic asphalt shingles are a popular choice for many homeowners due to their reputation as an affordable option for roofing.

Metal Roofing

There are at least 28% of metal roof installs in the United States. Metal roofs are designed for 140 mph winds. If the roof is installed well, it can last over 50 years. However, manufacturers guarantee 20-25 years

These roofs cost between $8,000 to $60,000. They come in two types, which include: 

  • Screw down: Corrugated metal roofs have exposed fasteners that come with rubber gaskets and are less expensive.
  • Standing seam: These metal roofs are developed from interlocking panels, and fasteners are concealed and are more expensive. They are often made of copper or higher gauge steel.

Copper roofing is a durable and visually appealing option, though it comes at a higher price point.

Clay and Concrete Tile

There aren’t many concrete tile roofs. These roofs are expensive, and labor costs are high. If you install these kinds of roofs well, they can last 50 years or more. The good thing is that these roofs are easy to repair. They cost an average of $8,000 to $50,000. 

Modified Bitumen Roof

These types of roofs are used in flat roofing applications. It means they are more effective if your roof has a pitch of about 1-3:12. 

The roofs come with a cap sheet and base sheet. Manufacturers offer a 15-year warranty on these roofs. Their estimated cost is between $8,000 to $16,000. 

Rubber (TPO)

TPO is also designed for flat roofs. They are developed from thermoplastic polyolefin, which is a synthetic rubber material. 

These types of roofs are used mainly for commercial roofs. However, they are gaining ground in residential roofs. They are repairable and have a manufacturer warranty of 20 years. However, it has higher prices than modified bitumen

The cost of a new roof is between $6,000 to $16,000.

Why Is Roofing So Expensive?

Materials and labor are the factors that make roofing expensive. But, make no mistake, using substandard materials and not hiring a professional could actually lead to more expenses.

A roof is an essential element of a house since it keeps you from harmful weather changes such as rain or hail storms. You should spend your money smartly on your roofing project to maintain your investment. 

Even though paying between $6,300 to $16,200 for a full roof replacement may look high, there is undoubtedly a good reason for such an action. You should spend a lot of effort, equipment, and time to keep your installation up to standard. 

If you want to replace your roof, you should get quotes for at least three to four professionals to get an accurate range.

You can also hire a roof inspector at the rate of about $125 to $325 to check whether you need to replace your roof. That way, you won’t have to spend so much on replacing the roofing when only minor repairs are needed.

You should check out this roof repair guide to get a deep insight into a complete roof replacement. The services and rates differ depending on the type of handyman and market. 

In most cases, re-roofing costs about $6,000 to $16,000. The labor you will pay for involves removing the original roof, repairing bad roof decking, adding a new underlayment, and new shingles. 

Asphalt and tiles are the most common roofing materials in the industry. They are developed using oil, clay, and concrete. Therefore, a rise in the price of oil can affect the prices of asphalt shingles. 

The cost of disposing of old roofing materials has also increased in recent years. 

How to Know When the Entire Roof Needs Replacing?

Focus on the following signs to know when your roof needs replacing:

  • Check if your roof is approaching its average lifespan.
  • Replace the roof when the shingles start to curl.
  • You should make a replacement when the whole shingles go missing.
  • Replace when the shingles crack.
  • Replace when you notice granules in the gutter. 
  • The shingles are covered with algae or moss.
  • Replace when the attic lets light through.
  • The roof is sagging.

You can also determine if a roof needs replacing through the type of material. Different roofing materials have different lifespans. The price of a new roof depends highly on the type of roofing material you choose.

If your home’s roof is in overall good shape and the roof leaks in one area, you shouldn’t need a full roof replacement. However, it’s best to replace the entire roof if you have extensive damage, missing shingles, hail damage, or signs of damage from high winds.

Generally, if more than 30% of the roof surface is damaged, most roofing contractors will recommend a full roof replacement. Patching an already leaky roof is a waste of money in the long run, and the best option is total roof replacement.

Your homeowner’s insurance company may cover a portion of the cost of replacing the original roof. You should get your roof inspected after a severe storm. Some roof replacement contractors offer a free estimate and will even assist with filing the insurance claim.

How Often Should a Roof Be Replaced?

As an inspector, I tell my clients they should consider roof replacement at 70% of the roof material’s life expectancy. This is generally the time when material age and weather will begin to cause roofing problems to occur.

In general, a roof should be replaced at the following intervals:

Roofing MaterialsLife ExpectancyWhen to Replace

Choosing the Right Roofing Company

Selecting the right roofing companies is crucial in ensuring you get a fair roof replacement cost. Experienced contractors can provide accurate roof estimates and guide you through selecting types of roofing materials.

Comparing Roof Repair Cost and Replacement Cost

Sometimes, a roof repair cost can escalate if there are underlying issues, making a complete replacement a more cost-effective solution in the long run. It’s important to compare roof repair cost to the investment of a complete replacement.

Frequently Asked Questions

For the money, architecture shingles are the best roofing material. Architecture shingles span 25 to 50 years, depending on their thickness. A 30-year architecture shingle should last 21 years or longer before total roof replacement will be necessary.

Can you shingle over old shingles?

Most roof structures can support the weight of two layers of shingles. Tearing off a roof is typically associated with longer repair and replacement times. Some local building codes prevent two layers of shingles, so check with your local municipality before starting a re-roofing project.

What is the easiest roof to install?

Asphalt shingles are the easiest roof materials to install. Almost 90% of all US homes have asphalt shingle roofs. Asphalt shingles are affordable, durable, and easy to install. Asphalt shingles can last 15 to 25 years, costing an average of $6,000 to $16,000.

Will a new roof increase home value?

If you are considering selling your home, a new roof is attractive to new homebuyers and can offer a good return on investment (ROI). A new roof can also improve the home’s curb appeal.

How much should I save for a new roof?

Most homeowners can expect to spend anywhere from $6,000 to $16,000 on a new roof. A new roof can cost up to $30,000 or more for larger homes with steep or complex roof systems. Your project budget accordingly and start with an estimate of at least $8,000 for a basic residential roof.

What do most roofers charge per square?

Most roofers charge between $350 and $900 per square ($3.50 to $9.00 per square foot), depending on the type of material used and the project’s complexity.
