FLAT ROOFING SPECIALISTS
Commercial Roofing in Toronto for Industrial & Commercial Buildings
50 years experience. Serving Toronto & the GTA. Emergency and planned work - we handle both.
Commercial roofing in Toronto isn't just about fixing leaks - it's about protecting buildings that operate year-round in one of Canada's toughest climates. At Crown Industrial Roofing, we specialize in flat roofing systems for commercial and industrial properties across the GTA, from repairs and maintenance to full replacements.
We work across Toronto - from North York and Etobicoke to Scarborough and the downtown core. We've inspected thousands of commercial roofs across this city. And honestly? Most problems we find could've been caught early - before they turned into a $60,000 replacement.
Whether you're managing a warehouse in Etobicoke or a plaza in Scarborough, Crown Industrial Roofing has been the contractor Toronto building owners call when it actually matters.
Why Toronto Businesses Have Trusted Us for Nearly Five Decades
Let's be direct about something. There are a lot of roofing companies operating in this city. Some are solid. Some disappear after the first invoice.
Crown has been here since 1976. That's not a marketing line - that's 50 years of completed projects, repeat clients, and roofs that are still performing the way they should.
Here's what that actually looks like:
50+ years in commercial and industrial roofing
Hundreds of completed projects across the GTA
Clients include warehouses, distribution centres, retail plazas, condos, and office buildings
Safety-certified crews, WSIB covered
Manufacturer-backed warranties on materials and workmanship
We're not a general contractor that does roofing on the side. This is all we do - and it shows.
SERVICES WE PROVIDE
Commercial Roofing Services in Toronto
Commercial roofing isn't one service - it's a system of ongoing maintenance, repair, and eventual replacement. Here's how we cover every stage of that system for buildings across the GTA.
Waterproofing
Not every situation calls for a full replacement. Waterproofing membranes can significantly extend roof life and improve energy performance - especially on roofs that are structurally sound but starting to show wear.
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, maintenance costs, and energy performance. We work with all major flat roofing systems 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.
Not sure which system is right for your building? That's exactly the kind of thing we walk clients through during an inspection.
Roofing Solutions for Commercial & Industrial Properties
This is where we differ from a lot of roofing contractors in Toronto. We don't do residential. We've spent 50 years focused on commercial and industrial work - which means we understand the specific demands of each building type at a level that general contractors simply don't. As a commercial roofing contractor in Toronto, we're dealing with these conditions and building types every day.
Warehouses & Distribution Centres
We've worked on warehouse roofs exceeding 50,000 sq ft - where even small drainage issues can turn into major operational disruptions. We know what these buildings need, and we know how to work around active operations so your facility keeps running.
Commercial 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 crews are professional, and we coordinate work schedules to keep impact on tenants as low as possible.
Condominiums
Condo boards need documentation, warranties, and accountability. We provide all three - including detailed post-inspection reports that satisfy both board requirements and reserve fund studies.
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.
Commercial Roofing Services Across Toronto & 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 maintenance 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 we've done work nearby.
Our Commercial Roofing Process
We'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, and our honest recommendation. No pressure, just information.
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.
Commercial Roofing Costs in Toronto
This is the part where most contractors 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.
What affects the cost:
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.
Ballpark ranges for context (Toronto market, 2024–2025):
Flat roof replacement for commercial buildings typically runs anywhere from $8–$20+ per square foot, depending on system, scope, and condition. Small repairs can start in the low thousands. Larger projects on industrial buildings regularly exceed six figures.
We're not going to pretend a number on a website is accurate for your specific building. What we will do is give you a proper, itemized quote - at no obligation.
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 done residential work. 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 work comes from property managers and building owners who've been calling us for years - some for decades. That kind of repeat business doesn't happen if the work doesn'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.
FAQs About Commercial Roofing in Toronto
Q: How long does a commercial 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 commercial roof be inspected?
Twice a year is the general standard - spring and fall. 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.
