A damaged and worn-out roof isn’t merely a problem for aesthetics. It can be quite dangerous too. We don’t need to elaborate on how an old roof can weaken the foundation of a building. Naturally, this isn’t something that anyone would want for their property. This is why people are quick to think about roof replacement at the first sign of the problem.

However, this is where things get tricky. While there are many things to consider during the roof replacement, money is among the most vital factors. The stress of budget is something that often prevents many from taking timely action on roof replacement. Knowing how much you will have to spend can make it easier for you to plan it all. So how much does roof replacement cost?

The average amount that an average homeowner has to churn out for new roof installation is around $8,264. Typically, you can expect to pay somewhere in the range of $5,000 and $12000.

But there are a lot of factors that influence the overall cost of roof replacement. Being aware of this can make the whole process smoother and more convenient for you.

Roof Replacement Cost By Material

One of the most vital decisions you have to make while replacing a roof is the material you want. There are plenty of choices in this regard, and the material you select will have a crucial impact on the roof replacement cost.

Indeed, you can think of the material as the driving force behind the budget you have to allot for the project. While the amount varies depending on the material you select, this should give you a fair idea of how much money will have to be invested if you go for any of these materials.

Roof Replacement Cost By Roof Type

Let’s make it clear. All roofs aren’t the same. They don’t merely have visual differences. Their designs determine how challenging the installation will be, which in turn affects your overall cost. Typically, flat roofs or those with a high pitch or numerous hips and curves cost more compared to others and understandably so.

Higher pitch implies that more roofing material is needed. And challenging roofing designs will require more labor on site. All this contributes to the total cost. Here are some of the most common roof types and the amount that goes into their installation.

Roof TypeCost per square footInstallation costLabor costTotal Cost
Flat Roof$3 - $10$4,000 to $13,000$3 - $7 per square foot$8,000 - 16,000

Roof Replacement Cost By Size

This is easily one of the most predictable factors that influence the cost of roof replacement. Naturally, the bigger the area of the roofing, the more material will be needed. The labor will have to put in more effort and give more time to the project. So it’s hardly surprising that the total cost increases with the size to be covered.

Size (Square Foot)Installation Cost
1,000$4,000 - $5,500
1200$4,500 - $6,500
1500$5,500 - $8,000

1800$6,700 - $9,500
2000$7,400 - $10,500
2500$9,000 - $13,000
3000$11,200 - $16,000

Roof Replacement Cost By Area

Yes, the roof of the house is undoubtedly the most common area for roof replacement. After all, this is what captures the most attention. However, this doesn’t imply that all other areas can be neglected.

Indeed, damage to the roof of your porch, shed, greenhouse, or garage can be quite detrimental too and needs timely action. The total cost of roof replacement in such areas is influenced by their size, type of roofing, and material. This should give you some idea of how much you will have to spend to replace the roof in different parts of your house.

Average Cost To Tear Off And Replace A Roof

Let’s face it. Replacing a roof isn’t as simple as it sounds. The old one has to be torn up; you have to determine what type of material you want now and the changes that will improve your roof condition. All this has a significant impact on the total cost.

On average, removal of the old roof can cost you anywhere between $1 and $5 per square foot, with the average being within the range of $1,000 and $1,500. Some roofing contractors prefer charging hourly for the project. Typically, the rate is $40 to $80 per hour.

However, there’s more to it. In case your roof has rotting timbers or new supports have to be installed, the cost will increase depending on the extent of material required. Indeed, the amount, in this case, can rise from anywhere between $1,000 and $10,000.

Therefore, it’s vital that you keep the roof removal cost in mind while thinking about replacement. Of course, the rate differs depending on the workload, your location, and many other similar factors.

Factors Affecting Roof Replacement Cost

So far, we have discussed some of the most obvious factors that influence the budget you should set aside for roof replacement. However, if you want a clear and accurate idea about the overall cost that will likely be required for the project, you need to know more. Here are the factors that have to be taken into account while determining the amount that will go into roof replacement.

Roof Pitch

Understandably, a steeper roof implies that replacing it will be more challenging. After all, the roofer will have to work on the steep system. More planning and labor will be required for the project. The underlayment will also be influenced by the roof slope. All this will increase the cost of roof replacement.

Roof Size

One of the first things that the roofing contractor will do before giving you an estimate of the project is calculate the square footage of the area. The area is measured and then divided by 100 to get the roofing square. One roofing square is equal to a hundred square feet. The roofing materials are sold by roofing square. Therefore, your total cost depends on this calculation.


If the roof isn’t easy to access, it will be tricky for the roofer to remove the existing materials before installing a new one. Easily accessible roofs have low replacement cost since the labor required for the job is less.

Waste Factor

You can’t expect some material not to be wasted in trims and cuts during roof replacement. This affects your total cost too. Professional roofing contractors add around 10 to 15% of the total square footage to get an estimate of the waste factor. However, the roof style and materials being used influence this significantly. More waste is produced in valleys, hips, and penetrations, which increases your cost.

Roofing Design And Shape

The architectural design of the roof matters too. Maybe you are inclined to have a combination of different roof types for your building. This will naturally cost more. The more complex the construction, the more you will have to pay for it.

Existing Roof Condition

If you wait until the last moment to get your roof replaced, you are in for some tough times. There’s a reason that it’s strongly advocated that you replace the roof at the first signs of damage. Heavily damaged roofs are more expensive to replace.

Think about it. Excessive damage implies that the underlying structure, too, will need some work. This will increase the material and labor required for the project. The structure will have to be repaired before the foundation can be laid for the new roof, which will add to your total cost.


Where you reside in the US also determines how much the roofing replacement will cost you. There’s a simple reason for this. The labor rates and price of materials differs in different regions.

Permits And Inspections

Many areas have strict rules regarding permits for roof installation. You have to acquire proper licensing from authorities. Naturally, some fees will be charged for the purpose, which has to be taken into account while determining the roof replacement cost.

The Charges Of The Roofing Contractor

Of course, you want the best roofing contractor for your project. After all, this is the safety of your building at stake, and you wouldn’t want to take any chances. However, the best comes at a price.

Roofing contractors usually charge per square for a roofing project, including labor and materials. You can ask for estimates from multiple contractors and compare rates before deciding who you want to go for.

Material Disposal Fees

The removed roof materials will have to be disposed of. The roofing contractor will add more charges for this.

DIY Roof Replacement Vs. Hiring A Roofer

A lot of people think that the budget for roof replacement by a roofing contractor exceeds their limit. They feel this is something that they can handle on their own. Is that really the case? In reality, roof replacement is one of those jobs that are best left to professionals.

For one thing, professional contractors have years of experience and knowledge. They are aware of how to work around the many layers of roofing materials. Many people don’t realize the complexity of the roofing system. A misstep at any point can be costly.

Roofers have the training which enables them to install all the roof components properly. They know the building costs and standards to be followed. Surely, you wouldn’t want to be on the wrong side of the law merely to replace your roof. Professional roofers can ensure that everything goes smoothly.

Of course, you can learn about your roof. But do you really have the time to understand all the complex layers and components for replacement? You have to realize that a problem with one shingle can lead to the whole installation being off.

What if you leave the nail heads exposed or end up using the wrong nail size? What if you don’t pull back the shingles above the new one properly? Indeed, there’s a lot that can go wrong during the roof replacement, and a DIYer can’t be expected to get everything right.

And of course, there’s the matter of insurance. If the roof incurs damage due to your wrong installation, can you really expect an insurance company to cover it? Unlikely!

Let’s face it. Professional roofers have much less risk of making mistakes than DIYers. And if that wasn’t enough, they have the insurance to cover their tracks. So you are in the safe zone even if something goes wrong during roof replacement since the contractor will take care of it all.

Lastly, there’s aesthetics to think about. Professional work reflects in the finesse. It’s not every day that you replace your roof. Why not go for the best and something that will last for a long time?
