About London Commercial Roofing
We're a London, Ontario commercial roofing company built around one idea: your building shouldn't be a side job squeezed between residential shingle work. Flat and low-slope commercial systems are our focus, and we serve building owners and property managers across London and Middlesex County.
Who we are
London Commercial Roofing is an owner-operated, locally-run company. We handle the parts that decide whether a roofing project goes well — the assessment, the honest recommendation, the written scope, the project management, and standing behind the finished job — and we deliver the work with trained, vetted roofing crews. You get one accountable point of contact from first look to final inspection, and one company whose name is on the warranty.
Because we're local, we actually know the buildings and the conditions here: the flat-roofed plazas and industrial units around White Oaks, Hyde Park and the east-end business parks, London's freeze-thaw swings and lake-effect snow load, and the City of London permit process. That's not a line — it's the difference between a roof detailed for Southwestern Ontario winters and one that isn't.
What you can count on
- Fully insured — commercial general liability that protects your property
- WSIB-compliant & IHSA safety protocols — our crews are covered and trained; you're not exposed if someone's hurt on your roof
- Registered Ontario business — a real, accountable company, not a truck and a phone number
- Manufacturer-certified installation — so your material warranty actually holds
- Written workmanship warranty — on top of the manufacturer's material warranty
- Commercial focus — flat, low-slope, TPO, EPDM, modified bitumen, and metal
How we work
We start with a free on-site assessment and a written, itemized quote — no vague ballparks, no pressure. We recommend a repair when it's the smart call and a full replacement only when it's genuinely warranted, and we tell you which and why. During the job we keep your building operating and communicate clearly. After it, we stand behind the work.
What our customers say
"We called to have our roof serviced and got a response quickly. The team arrived the same day and were courteous and professional. We'd recommend them to anyone."
— John, London
"Excellent at their job — attentive and genuinely careful about doing it right. Great quality of work, excellent service, and very competitive pricing. Highly recommended."
— Luke, Strathroy
"They inspected our flat roof and pointed out real deficiencies, then repaired it rather than pushing a costly replacement. It held through 2–3 days of straight rain with no leaks. Very pleased."
— Irving, St. Thomas
From full replacements to maintenance plans and 24/7 emergencies, across London and the surrounding towns, we keep Southwestern Ontario businesses dry and operating.
