How Much Does A New Roof Cost? 

The short answer is, it depends. Many factors influence the overall cost of getting a new roof. That said, the price differs for every household, and so, unfortunately, there’s no one straightforward answer to a specific situation. But if you want to get a rough estimate on how much roof replacements cost on average, here’s what we know: 

Depending on the current conditions of your roof and the roofing company you’d be working with, you might end up paying anywhere between $1200 to $30000. And according to HomeAdvisor, the typical cost is usually between $5569 to $11424. So you might be thinking, how on earth can you tell whether or not the price is right for your roof replacement project? 

Although the wide price range might make it seem like an unsolvable mystery, there are a couple of points that could help you evaluate the costs a bit better. Certainly, materials and the quality of work are both important determining factors, but that’s not all there is to it. 

To get the most bang for your buck, it’s important to first understand the processes involved in replacing your roof. Here’s a shortlist of what goes on in the undertaking: 

  • Removal and disposal of old shingles 
  • New underlayment installment 
  • Chimney reflashing, and 
  • Ice and water shield installment

If this is your first time getting a roof replacement done, these terms may sound too technical and complicated. Don’t worry; you can find further information down below. But before you go and dive deeper into the processes, let’s talk about the second tip on how to find out the right price to replace your roof. Apart from getting to know the processes involved, there are a bunch of other factors that affect the cost of getting a new roof. Read below for an extensive breakdown.  

What Factors Affect Roof Replacement Cost? 

As you now know, the price to replace your roof may vary greatly depending on a multitude of factors. But what exactly are they, and is there a way to cut down costs? Let’s find out. 

1. Roof Size 

The size of your roof is the largest factor that directly impacts the overall replacement cost of your roof. To put it plainly, the more surface area you need to cover, the more you have to spend on materials such as shingles, underlayment, and plywood. 

To identify how much material is needed, your roofing contractor would typically measure the square footage of your roof and divide it by 100 – or what contractors would technically call a roofing square. Simply put, a hundred square feet means one roofing square. This is important to note since materials are not sold by the square foot but by roofing square instead. 

Home Square Footage Vs. Roof Square Footage 

When looking up roof replacement costs on the internet, many homeowners would always use the size of their home as the basis of their research. However, it is important to understand that the square footage of your home is not the same as your roof square footage. 

The square footage of a house would normally include the measurements of all its living areas as well as each level that a house may have. However, this does not include basements, garages, and interior walls. Your home’s roof square footage, on the other hand, would also include measurements of the following spaces: 

  • Walkways 
  • Front entryways
  • Garage Spaces 
  • Overhangs, and
  • Lanais – if included in the home 

So how can you calculate your roof’s square footage? Although we highly recommend enlisting the help of a roofing company to do this, you can give yourself an estimate by multiplying the length and width (both in feet) of all flat planes and then getting the overall sum. 

How Much Does It Cost To Replace A Roof On A 1300 sq ft House? 

Most roofing contractors typically charge between $3.50 to $5.50 per square. Given these estimates, a new roof for a humble 1300 sq ft house would cost around $4550 to $7150. Please keep in mind that prices may be very different for your home, especially if you live in areas that are more prone to extreme weather and natural disasters. 

2. Roof Slope and Pitch

Apart from the size of the roof, its slope and pitch can also add up to its square footage. Again, this means the more space you have to cover, the more materials you’d need. A typical residential roof could have a low slope, a steep slope, or even a combination. 

With this in mind, your contractor may need to have special tools and equipment to work on a steeper roof – mostly for safety reasons. Having a steep roof could then also mean extra charges in the final bill. 

Measuring Your Roof’s Slope and Pitch Factor 

Unlike figuring out the square footage of your roof, calculating your roof’s slope and pitch requires more of your mathematical and geometry skills. Luckily, you can easily find out with the help of a calculator. But truth be told, it is simply easier to ask for help from your contractor. Not only will the results be more precise, but they will most likely have a handy chart that could simplify the whole process.

3. Roofing Materials 

The second-largest factor that greatly influences the price of your roofing project is the amount and value of the materials required. In general, there are nine types of materials you would need to replace your roof, and they are the following: 

  • Roof Decking 
  • Flashing for chimneys, skylights, etc. 
  • Underlay 
  • Shingles 
  • Ice and water shield
  • Drip edge
  • Ridge capping 
  • Roof vents, and
  • Pipe boots 

Homeowners typically have the freedom to choose which type of materials they would like to use for their roofs. But depending on the location of your home and your local building codes and rules, you may be required to install a particular type of material. 

As expected, roofing materials also vary in cost due to the differences in quality, performance, design, and durability. Take note that expensive options don’t always mean that they are the best solution for your project. Before deciding on the type of material for your roof, make sure to do a bit of research and see if there are affordable yet good-quality options for you. 

Also, have a chat with your contractor and ask what they would need because certain materials require a particular method of application or installation. For example, your roofing contractor may need to follow special instructions for a certain type of shingle in order to meet warranty standards. The same rule applies, especially if you’re looking at branded products as well. 

What Is The Most Affordable Material For Roof Replacement? 

If you’re looking for ways to cut down the cost of getting a new roof, you may want to consider getting asphalt shingles. Out of all the options out there, asphalt is probably the most pocket-friendly, followed by metal, tile, and, lastly, slate. Here’s a chart of what the price ranges look like for each material: 

  • Asphalt – $120 to $400 per 100 square feet 
  • Metal – $500 to $1800 per 100 square feet 
  • Tile – $600 to $4000 per 100 square feet 
  • Slate – $800 to $4000 per 100 square feet 

It’s tempting to choose the most affordable option out there, especially if you’re on a very tight budget. But keep in mind: there’s always a catch to choosing cost over quality. An asphalt roof will last you for only 30 or so years. But a roof made out of the higher-priced materials can last for about 50 or more years. Deciding which option is the better solution for your roof totally depends on you at this point. 

About Liability Insurance

Along with figuring out which materials are the best for your new roof, discuss the cost of the removal and installation of shingles with your contractor. Again, the prices vary widely depending on the tenure of your contractor. Newer and smaller companies may give you lower quotations but keep an eye out for abnormally low bids. 

More often than not, these companies can afford to give you a lower price because of the lack of liability insurance. Without insurance, contractors are not responsible for any damages that may occur, which means that homeowners will also have to pay for repairs from their pockets.

However, this also does not mean that you have to choose the contractor with the higher quotation. The higher cost doesn’t always mean a higher quality of work; even well-established companies hire subcontractors nowadays. When looking for a roofing contractor to work with, the rule of thumb is to do a bit of research yourself first – which is what you’re doing right now! 

4. Accessibility 

Much like having a steep roof, a home with a roof that’s not so easy to access will cost a lot more to replace. If your roofer finds it difficult to remove old shingles or install the new ones, you can expect to pay a bit more to get a new roof. Safety issues aside, a complicated roof situation also requires more skill and labor to get the job done. 

5. Waste Factor 

Did you know that it costs money just to get rid of your old roof? Contractors typically charge between 10 to 15% of your home’s total roof square footage as waste cost. Again, these are very rough estimates as the style, design, and even the material of your old roof influence the overall waste factor. 

Most of the waste will come from overlapped valleys and hips as well as cut-off material from flashings and gable ends. In some cases, your roofer may also need to rent a dumpster if they are faced with a bigger roof replacement project. 

6. Ventilation 

Most contractors may overlook the ventilation factor so that they can give you a more affordable estimate. While investing in better ventilation may seem like an added luxury to many, it may actually help you save a bit more money in the long run. Firstly, your home needs proper airflow in order to avoid mold growth in your attic. Additionally, ventilation can also help your home become more energy-efficient, giving you more opportunities to cut down costs on utility bills. 

7. Drip Edge 

Another part of the roof that contractors will often overlook is the drip edge. This area is the part of the roof that extends beyond the fascia. A lot of people don’t know this, but without a properly installed drip edge, water will not flow into the gutters as it should. This could cause rotting while the stagnant water attracts insects around your home as well. Besides, a drip edge can improve the overall look of your home, so why not invest in it if you’re upgrading your home anyway? 

How Do I Estimate The Cost Of New Roof? 

Still worried about getting the numbers right for your roof replacement project? We get it. Investing in a major home renovation needs proper planning, as it always involves spending your hard-earned money to get the job done. So if you’re still wondering how you can get an estimate for your new roof, here’s what you can do: 

Use an online calculator 

While you can do the traditional route and do all the maths by yourself, you can save time and energy by simply utilizing the internet. After all, most of the information you need is readily available online. Today, you can find online roofing calculators that can instantly give you a rough estimate of your roof replacement costs. 

Simply provide the measurements of your roof and voila, you have a quotation! Keep in mind, however, that it only accounts for the cost of materials. Other factors such as labor and other fees are not included. 

Contact Your Local Roofing Contractor 

You will eventually have to work with a roofer anyway, so why not seek their advice as well? Some roofing contractors even offer free estimates, so there’s absolutely nothing left to lose. Of course, we always recommend doing your own research first so you can compare your notes. But don’t hesitate to ask questions to your roofer when needed. 

The Bottom Line

So let’s do a recap. The cost of replacing a roof varies greatly, depending on the current state of your roof, the materials involved, and labor costs. However, there are some ways you can get a rough estimate as long as you have your roof’s measurements. You can either use an online roofing calculator or just have a chit-chat with your local roofing company.  

In the end, higher prices and quotations don’t always translate to higher quality work. The rule of thumb is to first do your research to make smart choices while also seeking help from experts.
