Flat Roofing
Industrial Flat
Roof Installation
Flat roof installation for plants, warehouses and large facilities across London and Southwestern Ontario.
Industrial flat roofing for large facilities
Industrial roofs are big, busy and full of penetrations. Vents, stacks, units and conduit all have to stay sealed. We plan industrial flat roofing work around your production schedule, coordinate access with your facility team, and keep the building watertight at the end of every shift.
We install EPDM, TPO and modified bitumen systems across large roof areas, with tapered insulation packages that move water to the drains. Everything is detailed for Ontario freeze-thaw conditions, follows Canadian Roofing Contractors Association guidelines, and comes with our two-year warranty and five-year maintenance plan.
What’s included
Large-area membranes
EPDM, TPO and mod-bit systems sized and staged for warehouse and plant-scale roof decks.
Penetration detailing
Stacks, vents, curbs and rooftop equipment flashed individually to keep water out at every opening.
Drainage engineering
Tapered insulation and drain layout that keeps ponding water off a big, flat deck.
Ongoing maintenance
Scheduled inspections that catch small issues before they interrupt production.

Industrial flat roofing FAQs
Can you install a roof without stopping production?
In most cases, yes. We phase the work, coordinate with your facility team, and seal each section before moving on.
What membrane suits an industrial roof best?
It depends on roof traffic, chemical exposure and budget. TPO, EPDM and mod-bit each have strengths. We’ll recommend one and explain why.
Do you handle roofs outside London?
Yes, we serve Southwestern Ontario including St. Thomas, Strathroy, Sarnia and Windsor.
How do you deal with all our rooftop equipment?
Every unit, stack and penetration gets flashed and sealed individually. That detailing is where industrial flat roofing services succeed or fail.
