SERVICES WE PROVIDE
Roofing Services in Toronto
Commercial roofing Toronto businesses depend on is not one thing — it is a system of ongoing care, repair and eventual replacement. Here is how our services cover every stage of that system for industrial buildings and businesses across the GTA.
Small repairs ignored have a way of becoming big replacements. We identify the source of the problem - not just the symptom - and fix it properly the first time. No patchwork. No shortcuts.
Sometimes a roof has just run its course. We'll tell you honestly when that line has been crossed. Full membrane replacements done on schedule, on budget - with guarantees that actually mean something.
A lot of building owners only call us when something's gone wrong. We'd rather catch the issue before your tenants are setting up buckets. Our team offers scheduled maintenance programs and ongoing roofing services for property managers and facility teams.
Storms don't care about business hours. Neither do we. If your roof is actively leaking and you need someone on-site fast - call us. We respond to emergencies across Toronto and the surrounding area.
Where moisture is suspected under the membrane, a thermal scan finds it without opening the roof up. It is the difference between replacing a wet section and replacing an assembly you never needed to touch.
Planning new rooftop work rather than fixing existing? We also handle rooftop installations and services, and our spring and fall roof inspection is free.
Commercial Flat Roofing Systems We Install
Choosing the right commercial roofing system is one of the biggest decisions building owners make - and it directly impacts lifespan, upkeep costs, and energy performance. We install all major flat roofing options and recommend the right one for your specific building, not just the easiest one for us to install.
TPO Roofing
One of the most popular systems for commercial buildings right now - and for good reason. TPO offers strong energy efficiency (its white membrane reflects heat) and reliable seam strength. A solid choice for most flat commercial applications.
EPDM Roofing
The workhorse of flat roofing. EPDM (synthetic rubber) has been around for decades and holds up well in cold climates. If you have a low-slope roof and want a low-maintenance solution, EPDM is worth considering.
Modified Bitumen
A multi-layer system with a long track record in commercial construction. Modified bitumen is especially effective on roofs with heavy foot traffic or complex penetration points. It's been our go-to for industrial facilities for years. B.U.R. replacement remains a core part of what we do.
Not sure which system is right for your building? That's exactly the kind of thing we walk clients through during an inspection. You can also explore the full range of flat roof installation and rooftop services we handle for commercial properties across the GTA.
Industrial Roofing Toronto Facilities Can Count On
Industrial roofing Toronto manufacturers need is a different animal from a retail plaza roof, and both are different again from a condominium.
Warehouses & Distribution Centres
We've worked on large-format warehouse roofs—where even small drainage issues can turn into major operational disruptions. We know what these buildings need, and we know how to operate around active operations so your facility keeps running.
Retail Plazas
Plazas have multiple tenants, multiple drainage challenges, and property managers who need clear communication. We've worked with landlords and management companies across the GTA who rely on us for both emergency calls and planned maintenance - because consistency matters when you're managing multiple leases.
Office Buildings
Appearance matters. So does minimizing disruption. Our team is professional, and we schedule our roofing services to keep impact on tenants as low as possible.
Condominiums
Condo boards need documentation, guarantees, and accountability. We provide all three - including detailed post-inspection reports that satisfy both board requirements and reserve fund studies. We also handle building envelope caulking and sealing for condominiums as part of a complete property care approach. building envelope caulking and sealing
Industrial Facilities
Chemical exposure, heavy equipment, ventilation systems - industrial roofs take a beating. We've been working on manufacturing and processing facilities for decades. Not much surprises us at this point.
Roofing Services Across Toronto, Etobicoke & the GTA
We operate across the full city and surrounding regions - including:
Toronto: North York, Etobicoke, Scarborough, East York, Downtown Core, York
GTA: Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Pickering, Ajax
We also understand how Toronto's climate impacts commercial roofs specifically - from freeze-thaw cycles in winter to heavy rainfall in spring and summer. These conditions are a big reason why service frequency and proper system selection matter here more than they do in milder regions. A roofing decision that works fine in Vancouver can underperform badly on a Toronto warehouse roof after two hard winters.
If you're not sure whether we service your area, just call. Chances are our roofing crews have handled jobs nearby.
Our Roofing Process
CWe've refined this over a long time. It's not complicated - but it does remove a lot of the uncertainty that building owners usually dread. .
Roof Inspection - We get up on the roof. We look at what's actually going on - not just what's visible from the ground.
Assessment & Report - You get a written report. Condition of the membrane, drainage performance, identified problem areas — including thermal scans for flat roofs where moisture is suspected — and our honest recommendation."
Transparent Quote - Line-item pricing. No vague estimates. You'll know what you're paying for before anything gets signed.
Project Execution - Our own crews - not subcontractors - complete the work. That matters for quality control and accountability.
Final Inspection & Warranty - We walk the roof with you before we consider the job closed. Warranties on both materials and workmanship are provided in writing.
What Drives Commercial Roofing Costs
This is the part where most roofers go vague. We'll give you more than that - but with the caveat that every roof is different.
We've quoted projects across Toronto ranging from small repair jobs to multi-building industrial replacements - so these ranges come from real jobs, not generic estimates.
There is no single number, and anyone quoting one over the phone has not seen your roof. Here is what actually moves the figure on commercial roofing Toronto projects:
Size - obviously. Larger square footage = higher material and labour cost.
Roofing system - PVC and TPO generally cost more upfront than EPDM or modified bitumen, but often last longer.
Current condition - if the deck underneath is compromised, that adds to the scope.
Access complexity - rooftop equipment, multiple levels, active tenants can all affect timeline and cost.
Repair vs. replacement - a good inspection helps you make this call before money gets wasted.
An inspection and a line-item quote cost you nothing and settle the question properly.
Why Choose Crown Industrial Roofing
There's no shortage of contractors in Toronto. Here's what actually separates us.
50+ years of commercial-only experience. We've never offered residential roofing services. Every job we've ever taken has been commercial or industrial - which means every decision we make is informed by that specific context.
No subcontractors. Our crews are our crews. That's how we maintain quality control on every project, regardless of size.
A documented process. From inspection to final sign-off, you'll know exactly where things stand at every stage. No surprises, no chasing invoices for clarity.
Long-term client relationships. A lot of our repeat business comes from property managers and building owners who've been calling us for years - some for decades. That kind of loyalty doesn't happen if the results don't hold up.
Honest assessments. If your roof doesn't need replacing, we'll tell you that. If it does, we'll show you exactly why. We'd rather keep a client for 20 years than oversell a job once.
"With over 50 years of experience, our expert technicians skilfully identify the causes of leaks. We attribute our success not only to our commitment to high-quality materials and exceptional workmanship but also to the dedication and expertise of our talented team. We offer competitive pricing and provide an industry-leading workmanship warranty directly covered by our company."

FAQs About Commercial Roofing Toronto Owners Ask
Q: How long does a flat roof last?
Depends on the system and how well it's been maintained. EPDM and modified bitumen typically run 15–25 years. TPO and PVC can push 25–30+ years with proper maintenance. We've seen roofs that lasted well beyond their expected lifespan - and some that failed in under a decade because of poor installation.
Q: How often should a flat roof be inspected?
Twice a year is the general standard - spring and fall roof inspection. That said, we'd also recommend an inspection after any significant storm, or if you're noticing interior water damage. Proactive inspection is almost always cheaper than reactive repair.
Q: Repair or replace - how do I know which one I need?
That's what an inspection is for. The honest answer: if less than 25% of the membrane is damaged, repair usually makes sense. Beyond that threshold, replacement often becomes the more cost-effective long-term decision. We'll tell you which way it goes - and why.
Q: What's the best roofing system for Toronto's climate?
Toronto's winters are hard on roofing membranes - freeze-thaw cycles, ice, and heavy snow loads all take a toll. TPO and PVC perform very well here due to their flexibility in cold temperatures. Modified bitumen is another solid performer with a long local track record. We'll help you match the system to your building's specific needs.
Q: Do you work with property managers and condo boards?
Yes, regularly. We're comfortable providing the documentation, reporting, and communication that property management situations require.
Q: Are you licensed and insured?
Yes. Crown Industrial Roofing is licensed, carries comprehensive general liability insurance, and is WSIB covered, with safety-certified crews on every site. Certificates are available on request, and warranties on materials and workmanship are issued in writing at final inspection.
Q: Do you handle residential roofs?
No. Every job Crown has taken since 1976 has been commercial or industrial. That focus is deliberate, and it is why commercial flat roofing Toronto owners and facility teams tend to stay with us once they have used us.
