Low-Slope & Commercial
Commercial & Flat Roofing in Edmonton
Commercial and flat roofing in Edmonton needs a membrane system, not shingles. Ellerslie Roofing installs and repairs EPDM rubber, TPO, and modified bitumen roofs for shops, garages, and commercial buildings, with proper slope and bulletproof detailing.
- EPDM, TPO, and modified bitumen systems
- Reinforced seams, curbs, and penetrations
- Drainage corrected to stop ponding
- Scheduling around your business hours
Flat Roofing Done for Edmonton Conditions
Commercial and flat roofing in Edmonton lives or dies on two things: how the water drains and how well the seams and penetrations are detailed. A flat roof is never truly flat; it needs enough slope to move water to drains so it does not pond, freeze, and work its way through the membrane. We build that into every project, then reinforce every seam, curb, drain, and pipe so the weak points stay sealed.
We work on a wide range of low-slope roofs:
- Retail, office, and small industrial buildings
- Strip malls and mixed-use properties
- Attached and detached garages with flat roofs
- Modern homes with flat or low-slope sections and decks
Signs Your Flat Roof Needs Attention
- Water ponding for more than a day or two after rain.
- Blisters, splits, or open seams in the membrane.
- Cracked or pulling flashing around curbs, drains, and walls.
- Interior leaks, ceiling stains, or damp insulation.
- A membrane that is brittle, shrinking, or past its expected lifespan.
Flat Roof Membrane Options
| System | Strengths | Good For |
|---|---|---|
| EPDM rubber | Durable, flexible in cold, proven track record | Many commercial and garage roofs |
| TPO | Reflective white surface, heat-welded seams | Energy-conscious buildings, larger roofs |
| Modified bitumen (2-ply) | Tough, multi-layer redundancy, good for foot traffic | Roofs with equipment and regular access |
Each system has a place. We recommend based on your building, budget, foot traffic, and how the roof drains, then install it the right way.
We also install 2-ply SBS modified bitumen and traditional built-up (tar and gravel) roofing where they fit, and we work with established membrane manufacturers such as Soprema and IKO. If you are not sure which system is right, we assess the existing roof and recommend the most cost-effective option.
Built for Edmonton's Climate
Flat roofs in Edmonton face a punishing cycle. Snow accumulates and sits, then melts during a chinook and refreezes, putting any standing-water weakness under constant pressure. Cold also makes some membranes brittle, which is why material choice and cold-weather detailing matter. We use systems proven in Alberta winters, correct slope and drainage to keep water moving, and reinforce the penetrations and curbs where flat roofs almost always fail first. The result is a roof that handles freeze-thaw instead of being slowly destroyed by it.
Our Commercial Roofing Process

Final Inspection & Cleanup
We water-test critical areas where appropriate and leave the site clean.
What Affects the Price of a Flat Roof?
- Roof area and access: larger roofs and difficult access affect labour.
- Membrane system: EPDM, TPO, and modified bitumen carry different costs.
- Insulation and slope correction: tapered insulation to fix ponding adds material.
- Penetrations and curbs: more units, drains, and pipes mean more detailing.
- Tear-off vs. recover: removing old layers versus going over a sound roof.
We provide a clear, itemized quote and a recommendation on repair versus replacement so you spend where it counts.

Why Edmonton Businesses Trust Us
30yr
Detailing That Lasts
A well-built commercial membrane delivers 20 to 30 years of service, but only if the seams, curbs, and drains are done right. We reinforce every penetration and correct slope so water leaves the roof. That detailing is the difference between a roof that lasts and one that leaks in year three.

FAQ
Commercial & Flat Roofing FAQs
What flat roof systems do you install in Edmonton?
We install and repair EPDM rubber, TPO, and 2-ply modified bitumen membranes. The right choice depends on the building, foot traffic, budget, and how the roof drains. We recommend a system after inspecting the existing roof and deck.
How long does a commercial flat roof last?
A well-installed commercial membrane typically lasts 20 to 30 years. Lifespan depends heavily on drainage, detailing at penetrations, and regular maintenance, which is why we slope to drains and reinforce every seam and curb.
Can you work around our business hours?
Yes. We schedule commercial work to limit disruption, including staging and sequencing so your building stays operational. We will coordinate timing, access, and safety with you before the project starts.
Do you repair flat roof leaks as well as replace them?
We do both. Many flat roof leaks come from failed seams, flashing, or ponding water and can be repaired. If the membrane is near end of life or failing in multiple areas, we will give you an honest comparison of repair versus replacement.
Why does my flat roof keep ponding water?
Ponding usually means inadequate slope or blocked or poorly placed drains. Standing water accelerates membrane breakdown. We correct slope with tapered insulation and improve drainage so water leaves the roof instead of sitting on it.
