Why Choosing the Right Commercial Roofer Matters

When it comes to commercial roofing, you’re not just hiring someone to install or fix a roof. You are choosing a partner who can affect your bottom line, reputation, and long-term building integrity.

The stakes are much higher compared to residential roofing. While a damaged residential roof might inconvenience a family, a failed roof on a commercial building could mean business interruptions, legal liability, and lost revenues. This is especially true for warehouses, retail stores, factories, schools, or office buildings where downtime results in financial losses.

Here’s why hiring the right commercial roofing company is critical:

1. Prevent Costly Downtime

Imagine discovering a roof leak during peak business hours—or worse, having to shut down operations for days because of water damage or unsafe working conditions. The cost of downtime for commercial properties can be substantial, not to mention the loss of customer trust.

The right commercial roofer will:

2. Ensure Compliance with Building Codes and Safety Standards

Ontario has strict building codes for commercial properties, especially when it comes to fire safety, insulation values, drainage systems, and accessibility. Hiring a low-quality roofer may expose you to risks, including:

Reputable roofing contractors understand provincial regulations and guarantee code-compliant installations—saving you from unexpected regulatory headaches.

3. Long-Term Performance and Durability

A commercial roof is an investment expected to last 15 to 40+ years depending on the system. But only if it’s installed right the first time. Improper flashing, inadequate slope, or poor material handling can lead to early failure—sometimes within just a few seasons.

Top-tier commercial roofers:

4. Energy Efficiency & Operational Savings

A well-installed roof does more than just shield you from the elements. It helps control your building’s temperature, reduces HVAC strain, and lowers energy bills. For large commercial spaces, this can mean thousands of dollars in annual savings.

Energy-efficient options like TPO, PVC, and reflective coatings are only as good as their installation. A high-quality roofer will also recommend proper insulation and drainage to prevent issues like ponding water or heat loss.

5. Access to Better Materials and Technology

Not all roofers are certified to install advanced commercial systems such as single-ply membranes, vegetative roofs, or solar-ready assemblies. Choosing a certified contractor ensures access to:

6. Post-Installation Support

The best roofers don’t disappear after the last shingle or membrane is laid. They offer:

With the right company, your commercial roof won’t just be installed; it can be managed and protected throughout its lifespan.

The key point is that a commercial roofing project is a major investment, not just in materials and labour, but also in the continuity and safety of your business. Therefore, don’t just go with the cheapest quote. Choose a company that’s experienced, transparent, and committed to doing the job right—because the roof over your business protects everything underneath it.

What Do Commercial Roofs Cost in Ontario?

One of the most common questions business owners and property managers ask is: “How much will a new commercial roof cost me?”

The answer depends on several factors, but understanding how roofers estimate the price of a project will help you prepare a realistic budget.

Commercial roofing costs vary significantly based on:

Factor	Effect on Commercial Roof Cost
Roof Size and Complexity	Large roofs are more expensive but the cost per square meter can decrease with scale. Skylights, multiple levels, and HVAC units increase labour costs and the total cost.
Type of Roof	EPDM, TPO, metal, BUR, and coatings all have different material and installation costs. Some of these are more labour-intensive and expensive.
Roof accessibility	High-rise roofs or hard-to-reach roofs require scaffolding and cranes which increase the overall cost.
Roof condition	Removal of the existing roof, deck repairs, or mould remediation can increase the cost of the project.
Insulation	Ontario’s climate requires strong insulation of R-values from 20 to 30 which help to save energy in the long term but increase upfront expenses.
Local Permits & Codes	Toronto, Ottawa, and other municipalities have specific permit fees and other requirements that affect the cost of the project.
Warranty & Workmanship Guarantee	Some high-end roofing companies may charge extra for longer warranties but they often provide better or longer protection.

The following table provides the average costs of a commercial roof based on roof type to guide you in preparing a budget for your roofing needs.

Type of Roof	Average Cost Per Square Foot	Average Lifespan
EPDM	$5 to $9	20 to 25 years
TPO	$6 to $10	15 to 20 years
Built-up roofing (BUR)	$6 to $12	20 to 30 years
Modified Bitumen	$5 to $9	15 to 20 years
Metal Roofing (Standing Seam)	$10 to $20++	40 to 50 years
PVC Roof	$7 to $11	20 to 30 years
Roof Coatings (Silicone, Acrylic)	$2 to $4	5 to 10 years

Please note that location, availability of the contractor, and seasonal demand can affect the overall cost of the project.

Don’t just pick the lowest quote you can find. Compare warranties and check on insulation and maintenance.

With a high-quality commercial roof installation, you can have peace of mind and feel assured that your roof will last a very long time.

Tips to save on Commercial Roofing Expenses in Ontario

A commercial roofing project is a major financial commitment, but that does not mean you have to break the bank.

Whether you’re replacing an aging roof or planning a new installation, there are ways to reduce costs without sacrificing quality or safety. From timing your project right to exploring alternative materials and rebate programs, the tips below can help you make the most of your budget while still getting a high-performance roof that lasts.

1. Consider getting roof coatings rather than full replacements if your roof is aging but still structurally sound.

2. Book during non-peak season (late fall or early spring) to get lower rates and more available contractors to choose from.

3. Get multiple quotes and compare warranties, scope of work, price, and reviews.

4. Inquire about energy rebates from the Ontario government or utility providers for reflective or insulated systems.

By taking a strategic approach by scheduling a roof installation off-season and comparing multiple quotes, you can potentially reduce the cost of your commercial roof.

A good contractor will guide you in opportunities to save on your expenses while meeting standards of safety, performance, and durability.

New Roof vs. Roof Repair: When to Replace a Roof

Repairs could cost from $500 to $5,000, depending on the severity of your roof’s condition. When do you repair a roof or just choose a new roof installation?

If your roof is more than 15 years old and is leaking repeatedly, the roof may have structural damage. It could be more practical to install a new roof than continue to use patch-over solutions.

While a new roof is a huge investment, you can recover the cost over time because of a longer lifespan, durability, and energy savings.

Benefits of Hiring Professional Commercial Roofers in Ontario

When it comes to protecting your commercial property, working with a professional roofing contractor isn’t just convenient; it is truly a good investment.

Ontario’s climate, building regulations, and commercial roofing systems all require specialized knowledge and experience. Here are the top benefits of hiring a qualified commercial roofing contractor in Ontario:

Increase in Property Value: Durable and well-maintained commercial roofs boost the value of your property.
Code Compliance & Safety: Commercial buildings anywhere in Ontario must follow strict codes, fire ratings, and safety standards. By hiring professionals, you can be confident that your roof is fully compliant, thus reducing the risk of fines, insurance issues, and legal complications.
Efficient Management: In commercial operations, time is gold. Roofing contractors know how to minimize disruptions to your operations and meet deadlines so your business can continue to run efficiently.
Long-term Savings: Regular maintenance of your roof can save you a lot of money on repairs. A good commercial roof can also lower your energy bills.

Why "Near Me" is Important when Hiring a Roofer

Hiring a local roofing company is not just convenient; it is also practical, especially in Ontario.

Local knowledge Translates to Better Performance

Roofers who work in your area understand the local climate challenges, from snow loads in North Bay to ice dams in Mississauga. They are also knowledgeable about the local building codes and permit requirements.

Faster service + accountability

A local contractor can respond more quickly to emergencies or issues after installation. If something goes wrong, it will be easier to communicate or follow-up.

Community reputation

Local companies rely on word-of-mouth and reviews to prosper. They care about their reputation and will often go the extra mile to protect it.

So when you search online for “roofing company near me,” you are saving time and making a smart and safe choice.

Look for local roofing companies near you using our short online form and receive competitive bids for your project, free of charge.

Always Check Licensing and Insurance

In Ontario, roofing companies are required to comply with provincial laws and workplace safety standards. Here’s what to check with potential contractors:

Business license: Make sure they are registered and operating legally.
WSIB coverage: The Workplace Safety and Insurance Board protects workers. If a contractor is not registered and someone gets injured, you could be held liable.
Liability insurance: This coverage protects your home from accidental damage while the job is in progress. It is ideal to hire a roofer with at least $1 to $2 million in coverage.

You should not take their word for it. Request copies of their certificates and verify that they are valid. Reputable roofing companies will be happy to provide any documents you need.

Check their Experience and Expertise

Experience matters, especially in something as important as your roof. Roofing isn’t just about laying shingles; it is also about proper underlayment, ventilation, flashing, drainage, and structural support.
If a roofer makes a mistake in any of these areas, you will experience leaks or even structural damage down the road.

Ask a potential contractor the following questions:

If you have a metal roof or a flat roof, hire a company that has a solid track record in metal roof or flat roof installation. Specialized roofing systems require specific techniques and materials which not all roofers have.

The Importance of Multiple Quotes

Look beyond the lowest price when you are searching for the right roofing company.

Always get at least three quotes. Don’t just compare the bottom-line price; rather, look at what’s included in the quote.

A detailed roofing quote should include:

Materials (type, brand, and quantity)
Labour costs
Estimated start and end date
Clean-up and disposal plan
Warranty information
Permit fees (if applicable)

If one quote is significantly cheaper than the others, be cautious. It could mean:

Choosing the cheapest option can end up costing you much more in future repairs.

Instead, aim for the best value for your money. You want a combination of competitive pricing, good workmanship, and a warranty that gives you peace of mind.

Checking references & Online Reviews

Checking online reviews before hiring a roofing company is one of the easiest and most powerful ways to protect yourself from a bad experience. Here’s why it matters:

1. Real Insight from Past Customers

Online reviews give you a credible perspective of what it’s actually like to work with the company. You can find out these helpful details:

2. Reputation Tells You a Lot

Roofing companies rely heavily on word-of-mouth. A roofing company with a consistent ranking of 4 or 5 stars across platforms is most likely a good roofing company you can trust.

A single bad review could be a fluke but multiple complaints from past customers is a red flag.

Pay attention to how the company replies to negative reviews. A professional roofer will address complaints respectfully and try to make things right. This shows accountability and strong customer service.

Fly-by-night companies create fake listings to find customers and then disappear fast after getting paid. A lack of online reviews or too many perfect reviews can also be warning signs.

Online reviews can help you choose a roofing company wisely. After all, you will be entrusting to this company your most valuable asset – your home.

Understand the Warranty Terms

Not all warranties are the same. Make sure you understand exactly what’s covered.

A warranty usually has 2 parts:

Questions to ask a potential roofer:

Reputable roofers are transparent about warranty coverage and will be explain in detail what to expect if something goes wrong. They are confident about the quality of their work and will not try to hide anything.

Roofing Company’s Communication and Professionalism

First impressions matter. Pay attention to how a roofing company responds to your calls or emails.

A roofing job can take several days, or even weeks, depending on the size and complexity of the project. You want to work with a company you feel comfortable dealing with and inspires your confidence.

A roofing company’s professionalism is also evident in:

If a company seems disorganized before they even start, it won’t get better once the job begins.

Red Flags to Watch Out For

Unfortunately, not every roofing contractor is honest or reliable. Be aware of warning signs such as:

No written estimate
Demands a large upfront payment or deposit (in excess of 20%)
No proof of insurance or license
High-pressure sales tactics
Cash only payments
Limited online presence
Unsolicited sales calls after a weather event

If you feel something is suspicious, trust your gut and stay away.

Cleanup and Post-Installation Support

The job isn’t done until your property is cleaned up and the roof passes inspection.

Ensure that your roofing contract includes the following:

A reputable roofing company will leave your property in a better condition as when they first began and will not disappear after they get paid.

You deserve a Roofer You Can Trust

Choosing a roofing company isn’t a light decision to make. A new roof installation is a costly investment and critical to your personal safety and the energy efficiency and value of your home.

Weather conditions in Ontario can be tough on your roof, which is why quality craftsmanship matters even more.

So when you are looking for a “roofing company near me,” take your time to do the following:

Understand what roofing work you need
Check licenses and insurance
Compare multiple quotes
Check references and online reviews
Compare warranties
Pay attention to how they treat you

The best roofing companies are skilled, communicative, reliable, and stand behind their work.

Find a roofing company near you that ticks all these boxes to ensure your roof will last for many years to come.

Replacing a roof is one of the most expensive home repairs that Canadians face, and, of course, the first question that comes to mind is: how much is a new roof going to cost me?

In this guide, we’ll break down everything you need to know about roof replacement costs in 2025 so you can find the best price and avoid hidden costs.

Key Factors That Affect Your Roof Replacement Cost

The size of your roof and the materials are the 2 most significant factors that impact the cost of your roof replacement.

Here’s a closer look at how your roof replacement cost is estimated by roofing contractors.

1. Roof Size and Shape

Larger roofs are more expensive. But it’s just about square footage; the complexity of the roof’s shape also affects the price. A simple gable roof is cheaper to replace than a steep, multi-level roof.

2. Location

Labour and material costs vary across the province. For example:

3. Choice of Materials

Asphalt shingles are budget-friendly but if you’re looking for longevity, metal or composite roofing may provide higher value over time.

4. Removal vs. Overlay

Are you planning to remove your old shingles or install new ones over them?

Expect to pay $1,000–$3,000 more for the removal of the existing roof, depending on the roof’s size and number of layers.

5. Underlayment & Decking Repairs

If the plywood decking underneath your shingles is damaged, you have to replace it. This can increase the cost by $50–$70 per sheet of plywood. The roofing contractor may not know until the shingles are removed.

Average Roofing Quotes across Ontario

If you live in Ontario, you’ll find roof replacement prices generally fall around the national average, with a few differences regionally, depending on whether you live in a major city or a smaller town.

Here’s what you can expect in Ontario this year for a typical 2,000 sq. ft. asphalt shingle roof:

City / Location	Low-End	Mid-Range	High–End

Ottawa	$9,500	$11,500	$14,000

Barrie	$8,500	$10,000	$12,500

Prices in the Greater Toronto Area (GTA) tend to be on the higher end, largely due to increased demand for skilled labour, higher wages, and the added complexities of working in densely populated urban environments such as parking restrictions, limited access to homes, and permit requirements.

On the other hand, homeowners in smaller Ontario cities or rural communities may get lower rates but only have a smaller pool of qualified roofers to choose from. This can affect service availability and scheduling.

Ontario Weather & Roofing: What to Consider

Ontario’s hot, humid summers to frigid, snowy winters take a toll on roofing materials. When replacing your roof, consider these weather-related tips:

Ventilation: Proper attic ventilation helps reduce moisture buildup in winter and excess heat in summer, prolonging the lifespan of your roof.
Choice of Shingles: Choose asphalt shingles rated for cold climate performance. Some brands perform better in freeze-thaw cycles.
When to Install: Spring to early autumn is ideal for installing a roof (May to October). This time frame has mild temperatures and dry conditions, ideal for roofing material adherence and good installation quality. Late autumn and winter roofing renovations are riskier due to adhesives not bonding well in cold temperatures.

Does a roof replacement increase home value?

Replacing a roof can increase the resale value of a home in Ontario.

While a roof replacement is mostly out of necessity or for maintenance, it gives the added bonus of increasing the home’s overall condition and curb appeal, making it a lot more appealing to potential buyers.

A new roof can help sell a home faster and at a higher price as it is an indication of a well-maintained property that reduces buyers’ concerns.

Studies show that homeowners could recover the cost of a roof replacement after a home sale with a potential ROI of 60% to 70% or more. As an example, a new roof that costs $25,000 can increase home value by $15,000 to $17,500.

A new roof can increase the home appraisal value which boosts the home’s perceived value.

FAQs about Flat Roof Installation in Canada

Flat roofs are common across Canadian homes and buildings—but they come with their own set of questions, especially when it’s time for a replacement.

From lifespan and costs to winter performance and walkability, homeowners often want clear, practical answers before making a decision.

Below, we answer the most frequently asked questions to help you understand what to expect from flat roof installation in Canada.

1. How long does a flat roof last in Canada?

With proper installation and regular maintenance:

Elastomeric (Modified Bitumen) roofs can last 25–30 years

EPDM rubber membranes last around 20–30 years

TPO membranes have a typical lifespan of 15–25 years

Harsh winters, UV exposure, and poor drainage can shorten this lifespan, so regular inspections are key.

2. Can I install a flat roof membrane in winter?

Technically, yes—but winter installations are more complicated.

Most contractors recommend waiting for spring to fall for optimal conditions.

3. What’s the best flat roof membrane for Canadian winters?

For cold-weather durability, Elastomeric (Modified Bitumen) and EPDM are the best performers.
They stay flexible in sub-zero temperatures and resist cracking and shrinkage. TPO can be suitable if a high-quality formulation is used and the installation is done professionally.

4. Do flat roofs always leak eventually?

While flat roofs are more prone to pooling and drainage issues, a properly installed and maintained membrane can remain watertight for decades. The key to leak prevention includes proper slope and drainage. Annual inspections are also necessary to catch early signs of potential problems.

5. Is a flat roof more expensive to replace than a sloped roof?

Flat roofs often have lower material costs, but labour can be more specialized and waterproofing and insulation could increase costs.

They usually cost $7–$15 per sq. ft., depending on membrane type, insulation, and location.

6. Do flat roofs increase or reduce home value?

A modern, well-maintained flat roof can enhance home value, especially in urban or contemporary builds. However, an old or poorly installed flat roof can deter buyers and reduce appraisal value.

Replacing a flat roof with the right membrane can recoup 60%–75% of the cost at resale.

7. How do I know if I need a new flat roof or just a repair?

These signs indicate you may need a full replacement:

A roofing inspection can confirm whether you can still repair the roof or it is time to get a new one.

Ready to Replace or Upgrade Your Flat Roof?

Choosing the right membrane is only the first step. Getting a quality installation from a trusted, experienced roofer is what makes the difference between a leak-free 30-year roof and a costly headache in 5 years.
