When it comes to home maintenance, one aspect that often gets overlooked, but is of utmost importance, is the roof.

The roof serves as our shield against the elements, protecting us from rain, snow, and scorching sun.

However, over time, roofs can deteriorate due to wear and tear caused by Ottawa’s unpredictable climate.

That’s where roof replacements comes into play. A roof replacement is a significant undertaking that requires careful planning and consideration.

From labour costs to choosing the right roofing materials, there are several factors to take into account.

Additionally, finding a reliable roofing contractor in Ottawa is crucial for ensuring a quality job that will stand the test of time, and who have experience working in Ottawa’s climate.

Average Roof Replacement Cost in Ottawa

When it comes to replacing your roof in Ottawa, one of the most pressing concerns is the average cost.

Understanding the average roof replacement cost can help you plan your budget and make informed decisions. In Ottawa, several factors come into play when determining the cost of a roof replacement.

Firstly, the type of property you own plays a significant role in determining the average cost. Townhomes tend to have smaller roof sizes and thus lower replacement costs compared to single-family homes or large complex houses with extensive roofing areas.

The square footage of your roof will directly impact the overall cost as more materials and labour will be required for larger roofs.

Secondly, consider the roofing materials you choose for your replacement project. Asphalt shingles are a popular choice due to their affordability and durability.

They are widely available in Ottawa and offer various styles, such as architectural shingles that enhance the aesthetic appeal of your home.

Metal roofs are another option, known for their longevity and resistance to extreme weather conditions characteristic of Ottawa’s climate.

Roofing Materials Ottawa

Labour costs also play a significant role in determining the average roof replacement cost. Hiring a reputable roofing company or contractor in Ottawa is crucial to ensure quality workmanship and adherence to building codes.

Labour costs vary depending on factors such as experience, expertise, and demand within the market.

Additionally, disposal fees should be taken into account when calculating overall costs. Many municipalities charge fees for disposing of old roofing materials responsibly at designated facilities.

So how much do roofs cost in Ottawa?

Going off the price range of the most popular roofing material, architectural shingles, your roof can lead to costs ranging from $6,000 to $35,000, influenced by the roof’s size and intricacy.

For townhome residents, roofing expenses tend to be on the more affordable side, typically between $6,000 and $10,000.

Those inhabiting a spacious 2500 square foot home can anticipate roofing costs from $12,000 up to $20,000.

Meanwhile, if you reside in an expansive residence, your roofing bill may start at $20,000 and could soar to $40,000.

Overall, it’s essential to obtain multiple roofing quotes from reputable Ottawa roofing experts before proceeding with a replacement project. This will give you an idea of pricing variations based on material choices, labour rates, warranties offered by different contractors or companies.

Key Factors Influencing Roof Replacement Costs

For homeowners in Ottawa, the roof replacement journey is not just about finding the cheapest option. It’s a balance between upfront costs, long-term savings, and ensuring that the roof stands strong against the city’s diverse weather conditions.

By thoroughly understanding the following key factors and consulting with experienced roofing professionals, homeowners can make an informed decision that adds value and protection to their home for years to come.

Material Choice

Different roofing materials come with their own set of advantages and price points. Architectural shingles, for instance, are popular due to their affordability and variety of styles.

In contrast, metal roofs, although more expensive initially (double to price of architectural shingles), promise extended durability and can withstand harsh weather conditions.

Tile roofs, with their distinct appearance, offer longevity but may necessitate structural reinforcement due to their weight.

Roofing Materials Ottawa

It’s crucial to consider not just the initial investment but also the material’s lifespan and maintenance needs.

Labour Costs

The expertise of the contractor and the intricacy of the design significantly dictate labour expenses. The rule of thumb is, the bigger and more complex the roof, the more days it takes roofers to complete the roof, and therefore, the labour costs will be higher.

Hiring seasoned professionals might be pricier, but their vast experience guarantees precision and longevity, potentially reducing future repair costs.

Furthermore, labour costs can fluctuate based on seasonal demand; during peak times, contractors might charge a premium, while off-peak periods might offer opportunities for better deals.

Roof Size

The size of the roof directly corresponds with the overall cost. Larger roofs demand more materials and extended labour hours, leading to a higher price tag.

However, the silver lining is that a larger roof might have a longer lifespan due to the distributed wear and tear, offering long-term benefits to homeowners.

Roof Complexity

The design of the roof plays a pivotal role in cost determination. Steeper roofs or those featuring intricate designs like multiple angles, valleys, and skylights necessitate specialized equipment and heightened safety measures.

Such designs, while visually appealing, can add to the project’s complexity, demanding more time, effort, and thus, money.

Roof Replacement Ottawa


Investing in extended warranties can slightly elevate the initial cost, but they are a boon in the long run.

These warranties shield homeowners from potential unforeseen issues, ensuring peace of mind. While some companies might offer these at an additional charge, the future savings and security they provide can often outweigh the initial expense.

Disposal Fees

The aftermath of a roof replacement involves discarding old materials, which can incur additional charges.

Local regulations can influence these costs, and methods like recycling, while environmentally friendly, might also offer cost benefits. It’s essential to factor these fees into the budget, ensuring no unexpected surprises.

Independent Contractors vs Roofing Companies

The roofing industry is full of ‘fly-by-night’ roofing contractors, who operate out of their trucks, and underbid the top roofing companies of Ottawa.

Depending on the size of your home, these roofing contractors can underbid established business by a few thousands dollars on a townhome, and up to ten thousand dollars on larger homes.

Note that going with these independent contractors comes with many risks. One, they are not incentivized to do a good job. Most home owners don’t have the expertise to evaluate a job and these roofing contractors want to complete a home as fast as possible to earn the most amount of money.

Two, they do not have WSIB, liability insurance, workmanship, or material insurance. If something goes wrong with your roof, the expense will come out of your pocket as the roofing contractor will not return your calls, and your insurance company will not help you with your problems.

On the other hand, hiring a professional roofing company brings several advantages. These companies typically have a team of experienced roofers who specialize in different types of roofing materials such as asphalt shingles or metal roofs, and are experts in residential roofing.

They often provide warranties on their workmanship and materials used, giving you peace of mind knowing that any potential issues will be addressed. Moreover, reputable roofing companies in Ottawa usually have insurance coverage for their workers.

This is crucial because accidents can happen during construction projects like roof replacements. Having insurance protects both you as the homeowner and the workers involved.

Another advantage of working with a roofing company is that they typically handle all aspects of the project from start to finish. They will provide an accurate quote based on factors such as square footage, roof pitch complexity, disposal fees for old materials, labour costs per hour for their team members — taking away much of the stress associated with managing multiple contractors yourself.

Choosing between hiring independent contractors or opting for a professional roofing company ultimately depends on your priorities and budget considerations. If saving money is your primary concern, independent contractors may be the way to go.

However, if you value expertise, warranty coverage, and a streamlined project experience, it’s worth investing in a reputable roofing company in Ottawa. Consult with local roofing experts to get their recommendations and quotes before making a final decision.

Roof Installation Process

Once you’ve made the decision to replace your roof, it’s important to understand the installation process. This involves several steps that a professional roofing company or contractor will follow to ensure a successful and long-lasting result. Firstly, they will start by removing the existing roofing materials.

This typically includes tearing off any old shingles or tiles and disposing of them properly. Depending on the size of your roof and the type of materials being removed, there may be disposal fees involved.

Roof Installation Ottawa

It’s always best to clarify this with your roofing company or contractor beforehand. Next, a thorough inspection of the underlying structure will take place.

This is crucial for identifying any potential issues that need to be addressed before proceeding with the installation. Ottawa roofing experts will inspect for signs of rot, water damage, or structural weaknesses that could compromise the new roof’s integrity.

Afterwards, they will install an underlayment, which acts as a protective barrier between the roofing materials and your roof deck. The underlayment helps prevent moisture from seeping into your attic or living spaces.

The specific type of underlayment used may vary depending on factors such as climate and roof lifespan. Once the underlayment is in place, it’s time for the main event: installing the new roofing materials!

Whether you’ve opted for asphalt shingles, metal roofs, architectural shingles, or another material altogether, skilled professionals will carefully lay each piece according to manufacturer guidelines and industry best practices. Throughout the installation process, Ottawa roofing experts pay close attention to details like proper nail placement and ventilation requirements.

These factors contribute to extending your roof’s lifespan and ensuring its durability in Ottawa’s ever-changing seasons. When everything is complete, it’s essential to review all documentation provided by your chosen roofing company or contractor.

This includes reviewing warranties for both labour and materials used in your roof replacement project. Understanding what these warranties cover can provide peace of mind knowing you’re protected if any issues arise in the future.

The roof installation process involves removing old roofing materials, inspecting the underlying structure, installing an underlayment for protection, and then carefully installing the selected roofing materials. Ottawa roofing experts follow best practices to ensure a high-quality result.

It’s important to review warranties and any associated fees or requirements before starting your project. By working with a reputable roofing company or contractor, you can have confidence in the longevity and performance of your new roof.

Roof Replacement vs Roof Repairs

When it comes to the roofing game, homeowners often find themselves grappling with the decision of whether to replace their entire roof or simply opt for repairs.

It’s a common dilemma, and understanding the pros and cons of each option is crucial in making an informed choice. Let’s start by taking a closer look at roof replacement.

This involves tearing off the existing roofing materials and installing a brand-new roof from scratch. While it may seem like a more drastic measure, there are several advantages to going this route.

Firstly, a new roof can significantly enhance your home’s curb appeal and potentially increase its market value. Secondly, it offers you the opportunity to select modern roofing materials that are more durable and energy-efficient than what you currently have.

Roof Repairs, on the other hand, if your roof issues are localized and don’t require a complete overhaul, opting for repairs might be the way to go. Repairs involve fixing specific areas or components of your roof that are damaged or showing signs of wear and tear.

Pre-Purchase Roof Inspection

This option is typically more cost-effective in the short term since you won’t have to shell out for an entire replacement upfront. Factors to Consider: When deciding between replacement or repairs, there are several factors you need to consider.

The first one is the overall condition of your roof. If your current roofing system is nearing the end of its lifespan or has undergone multiple repairs over time, a full replacement might be necessary for long-term peace of mind.

Additionally, if there are extensive issues such as widespread leaks or structural damage, repairs may only offer temporary solutions. Budget is another key consideration when making this decision.

What To Do If You Have A Leaking Roof

While roof replacements can be pricier upfront due to material costs and labour fees associated with tearing off old shingles and disposing of them properly, they provide better long-term value by ensuring that your entire roof is solidly built from top to bottom. It’s important to consult with Ottawa roofing experts to assess the specific needs of your roof.

They can provide you with a detailed roofing quote, highlighting the cost breakdown for repairs versus replacement. They will take into account factors such as square footage, roofing materials, disposal fees, underlayment requirements, and labour costs when providing you with an estimate.


When it comes to roof replacement costs in Ottawa, there are several factors to consider. The unique climate of Ottawa plays a significant role in determining the lifespan and durability of roofing materials.

Metal roofs are becoming increasingly popular due to their longevity and resistance to harsh weather conditions. However, asphalt shingles remain a cost-effective option for many homeowners.

Labour costs can vary depending on the size and complexity of the roof, as well as the type of roofing material being installed. It is important to obtain multiple roofing quotes from reputable contractors or roofing companies in Ottawa to ensure you are getting a fair price.

Additionally, considering warranties and insurance coverage is crucial for protecting your investment. While roof replacement may seem like a substantial expense, it is an investment that can increase the value of your home and provide peace of mind for years to come.
