[ Our Story ]
15+ Years Building Roofs That Last
KSC Construction — operating as Toiture KSC — was built around a simple idea: a roof in Quebec has to survive freeze-thaw cycles, wind and snow that would destroy a poorly built system within a few winters. That means no shortcuts on materials, no rushed flashing details, and crews who specialize in shingle roofing and torch-on elastomeric membrane.
Today we serve homeowners, condo boards, property managers and commercial clients across the Island of Montreal, Laval and the South Shore — installing new roofs, repairing failing ones, and running emergency dispatch 24 hours a day for the leaks that can't wait until morning.
Deep roots in Quebec roofing
Our crews have specialized in shingles and torch-on elastomeric membrane for over 15 years, working through more Montreal winters than most roofs ever see.
Projects completed
From single triplex repairs to multi-building commercial re-roofs, we've delivered over a thousand projects across the region.
Licensed & insured
Fully licensed under the Régie du bâtiment du Québec and insured for both residential and commercial work.
[ How We Work ]
Diagnosis first. No surprise quotes.
Every project starts with an honest assessment — whether that means a full installation, a targeted repair, or simply monitoring a minor issue. We quote what the roof actually needs, not what's easiest to sell.
Certified crews, premium materials sized for our climate, and a written warranty on every job are the baseline, not the upsell.
