FLAT ROOFS ARE OUR SPECIALTY
Commercial Roofing Contractors with 28+ Years of Experience
Every commercial flat roof in Ontario is fighting the same battle — freeze-thaw cycles pulling membranes apart, UV breaking down surfaces all summer, and water finding every weak point in between. The buildings that last are the ones with roofing systems that were installed correctly and maintained consistently.
At Videl Roofing, that’s all we do. We install, repair, and maintain flat roof systems — mechanically fastened membranes, torch-applied modified bitumen, TPO, EPDM, and built-up roofing — for commercial properties across Southern Ontario.

COMMERCIAL BUILDINGS WE SERVE
Roofing Solutions for Every Type of Commercial Property
Flat roofs behave differently depending on the building they protect. A strip plaza with six HVAC units and a grease exhaust has different failure points than an apartment building with aging parapet walls. We tailor our approach to match the building, not the other way around.
Retail and Strip Plazas
High tenant turnover means HVAC units get added, removed, and relocated without proper flashing — and every change leaves the membrane exposed.
Grease exhaust from food tenants accelerates membrane breakdown around penetrations
Tenant-installed signage and equipment often punctures the membrane without proper sealing
Multiple HVAC units create concentrated stress zones and drainage obstructions
Ponding water collects around improperly flashed curbs and drains between units
Multi-Tenant Office Buildings
Office buildings depend on consistent climate control and clean, dry interiors. A single roof leak can damage suspended ceilings, disrupt electrical systems, and trigger tenant complaints that escalate fast.
Aging rubber membranes shrink over time, pulling seams apart at the most vulnerable joints
Rooftop HVAC units vibrate constantly, loosening flashing and creating micro-tears in the membrane
Clogged or undersized drains cause water to pond, adding weight and accelerating deterioration
Elevator shaft penetrations are common leak points that often go undetected until interior damage appears
Apartment Buildings
A roof failure overhead can cascade through multiple units, damaging drywall, flooring, and personal property — and creating liability exposure for the building owner.
Flat roofs on 1960s and 1970s apartment buildings are often well past their original service life
Rooftop vents, pipes, and mechanical penetrations deteriorate faster than the surrounding membrane
Interior leaks often appear far from the actual roof failure, making diagnosis difficult without professional assessment
Insurance claims require documented roof condition history that most buildings don’t have until it’s too late
Warehouses and Distribution Centres
Large, open-span roofs are exposed to significant thermal movement, heavy equipment loads, and limited drainage slope. Small problems on these buildings become expensive ones fast.
Wide membrane spans with minimal slope create persistent ponding zones
Rooftop units on warehouse roofs are often oversized and under-flashed
Dock door areas create thermal breaks where condensation and ice damage the membrane edge
A single leak over stored inventory or equipment can generate losses far exceeding the cost of the roof repair

COMMERCIAL ROOFING SERVICES
Repairs, Replacements, and Maintenance for Commercial Flat Roofs
Whether you’re dealing with an active leak or planning a replacement two years out, our commercial roofing services cover every stage of your roof’s life — from first inspection to final membrane.
Flat Roof Repairs
Targeted repairs for membrane splits, failed flashings, and seam separations on commercial properties. We trace every leak to its source and fix the root cause, not just the visible symptom.
Roof Repairs
Roof Replacements
Full roof system replacements built for long-term performance. From insulation to membrane, every layer is specified for your building’s structure, use, and climate exposure.
Roof Replacement
Emergency Roof Repair
Water coming through the ceiling at your plaza or office building? Our emergency crew responds within 90 minutes to contain the damage, protect interior assets, and stabilize the roof.
Emergency Repairs
Roof Penetrations
Every HVAC curb, vent stack, drain, and skylight is a potential failure point on a commercial roof. We flash, seal, and reinforce each penetration to prevent leaks and protect the surrounding membrane.
Roof Penetrations
Waterproofing
Reinforced seams, resealed flashings, and protective coatings applied to the areas most vulnerable to water intrusion. Designed to extend the service life of your existing commercial roof system.
Industrial Waterproofing
Skylight Repair & Install
Cracked lenses, failed seals, and deteriorating curb flashing make skylights one of the most common leak sources on commercial roofs. We repair or replace skylights and reinforce the surrounding membrane to stop water intrusion at the curb.

COMMERCIAL ROOF TYPES
What Kind of Roof Is on Your Building?
Most commercial property owners and managers don’t know what roof system they have until something goes wrong. Every project starts with a free on-site assessment that identifies your current system, documents its condition, and provides an honest recommendation on what it needs.
4-Ply Built-Up Roofing (BUR)
The original commercial flat roof system — and still one of the most durable options for buildings with the structural capacity to support the weight. If your building was constructed before the mid-1990s, this is likely what you have.
Composed of alternating layers of asphalt and reinforcing felt, topped with a protective gravel surface
Built-in redundancy means even if the top layer is damaged, the underlying layers continue to protect
Excellent resistance to foot traffic, UV exposure, and standing water
Best for large commercial buildings with strong deck structures and high equipment loads
EPDM (Rubber Roofing)
A flexible synthetic rubber membrane that has been a go-to system on commercial buildings for decades. Affordable, reliable in cold climates, and efficient on large roof areas.
Wide rolls minimize seam count, reducing the number of potential failure points
Highly flexible in cold temperatures, well-suited to Ontario’s freeze-thaw cycles
Older EPDM systems are prone to seam separation and membrane shrinkage over time
Best for wide-span commercial roofs with moderate foot traffic and limited rooftop equipment
TPO (Thermoplastic Polyolefin)
One of the most widely installed commercial roofing membranes in North America. Energy-efficient, durable, and available in a reflective white surface that reduces cooling costs.
Heat-welded seams form a continuous watertight bond stronger than the membrane itself
Reflective white surface can meaningfully reduce summer cooling costs on large commercial buildings
Lower long-term maintenance costs compared to BUR and EPDM when properly installed
Best for new commercial construction, energy-conscious retrofits, and buildings with rooftop equipment
Metal Roofing
Designed for commercial buildings with low-slope or slightly pitched roof structures. Interlocking steel or aluminum panels provide long-term weather protection with minimal maintenance.
Coated panels resist corrosion, rust, and wind uplift
Long service life with significantly lower maintenance requirements than membrane systems
Can be insulated and retrofitted over existing low-slope roof structures
Best for commercial storage buildings, retail outbuildings, and structures with slight roof pitch

Not sure if it’s time to repair or replace?
The answer depends on the age of your system, the extent of the damage, and what you’re spending on reactive fixes each year.
Our Flat Roof ROI Calculator helps you compare the cost of maintaining your current roof against the cost of replacing it — so you can make that decision with real numbers.

Insights & Expert Roofing Advice

What types of commercial buildings does Videl service?
Any commercial property with a flat roof — retail plazas, multi-tenant offices, apartment buildings, warehouses, medical centres, and institutional buildings across Southern Ontario. If it has a flat roof, we can help. We do not work on residential shingle roofs.
How do I know if my commercial roof needs repair or replacement?
If the damage is isolated — a failed seam, a cracked flashing, or a single ponding area — repair is usually the right call. If your roof is 20 to 30 years old, you’re seeing widespread membrane deterioration, or you’re spending more on annual repairs than a planned replacement would cost, it may be time to replace. We assess both options honestly during our free on-site evaluation.
How much does a commercial roof replacement cost in Ontario?
For most commercial flat roof systems in Ontario, full replacement ranges from $8 to $18 per square foot depending on the membrane type, insulation requirements, accessibility, and whether a full tear-off is required. We provide detailed, line-item estimates based on a thorough site assessment.
What should I do if my commercial roof is leaking right now?
Call us. Our emergency crew responds within 90 minutes to assess the situation, contain water intrusion, and protect your interior. Even if conditions prevent a permanent repair the same day, we’ll stabilize the roof and prevent further damage.
Is preventative maintenance worth it on a commercial roof?
It’s the single most cost-effective thing you can do. Routine inspections and minor repairs through our Preventative Roof Maintenance Plan can extend your roof’s life by 5 to 10 years, reduce emergency costs, and give you documented condition history for insurance and capital planning.
Can you help us budget for a future roof replacement?
Yes. We work regularly with property managers and building owners to provide condition reports, replacement timelines, and cost estimates for capital planning. Getting an accurate picture of your roof’s remaining life now lets you budget on your terms instead of reacting to an emergency. See CAPEX planning for property owners and managers.
What should I look for when choosing a commercial roofing contractor?
WSIB compliance, adequate liability coverage (ours is $5 million), manufacturer partnerships, and verified experience on commercial properties. Beyond credentials, look for a contractor who communicates clearly, shows up when they say they will, and gives honest recommendations — even when the honest answer is that you don’t need to spend money right now.
