Shingle Roof Installation
Learn More →How long does a shingle installation take?
Most residential roofs are completed in 1–3 days depending on size and weather. Larger buildings are scheduled in sections to limit disruption.
Can you install over my existing shingles?
Sometimes — it depends on deck condition and how many existing layers are already in place. Our site assessment will tell you whether a tear-off is required.
What warranty comes with a new shingle roof?
Every installation includes a written 10-year warranty on materials and workmanship, backed by our RBQ license and insurance.
Do you handle permits?
Yes — we confirm what your municipality requires for a full re-roof and handle the paperwork as part of the project scope.
Torch-on Roofing
Learn More →How long does a torch-on installation take?
Most residential and small commercial roofs are completed in 2–5 days depending on size and weather. Larger buildings are scheduled in phases so occupied sections stay watertight throughout.
Can you install over my existing roof?
Sometimes — it depends on deck condition and how many existing layers are already in place. Our site assessment will tell you whether a tear-off is required or whether a re-cover is structurally sound.
What warranty comes with a torch-on membrane?
Every installation includes a written 10-year warranty on materials and workmanship, backed by our RBQ license and insurance.
Torch-on or shingles — which do I need?
Shingles suit pitched roofs; torch-on elastomeric membrane is built for flat and low-slope roofs. We assess your building and recommend the right system.
Repair & Waterproofing
Learn More →Is the diagnosis really free?
Yes. We inspect and identify the leak source at no charge, and you only pay if you approve the repair scope.
Can a torch-on membrane or shingles be repaired instead of replaced?
In most cases, yes — isolated blistering, seam failure, damaged shingles and flashing issues are all repairable. We only recommend replacement when failure is widespread.
How fast can you get someone out for a leak?
Non-emergency repairs are typically scheduled within a few business days. For active leaks, see our 24/7 emergency service.
Do you waterproof foundations or balconies too?
Our waterproofing work is focused on roof membranes, flashing and related building envelope details — ask us if your project falls in that scope.
24/7 Emergency Service
Learn More →What's your response time for an emergency call?
We dispatch as soon as a call comes in, prioritizing active leaks and structural risk. Exact arrival time depends on your location and current conditions, but we operate 24/7, 365 days a year.
Will the tarp be a permanent fix?
No — emergency tarping stabilizes the building immediately. We follow up promptly to schedule the permanent repair once conditions allow.
Do you provide documentation for insurance?
Yes, we photograph and document the damage as part of the emergency call, which you can submit with your claim.
What areas do you cover for emergencies?
The Island of Montreal, West Island, Laval, Longueuil and the South Shore — see our service areas for full coverage details.
Island of Montreal
Learn More →Do you work on shared triplex roofs?
Yes — triplex and multi-unit flat roofs are among our most common jobs on the island, and we coordinate with co-owners or the syndicate where needed.
Can you work on occupied commercial buildings downtown?
Yes, we schedule and stage work to keep occupied commercial buildings watertight and operational throughout the project.
How quickly can you respond to a leak on the island?
We run crews across Montreal daily, and offer 24/7 emergency dispatch for active leaks.
West Island
Learn More →Do you offer West Island roofing services?
Yes — the West Island is part of our daily coverage across the Island of Montreal. We offer installation, repair, waterproofing and 24/7 emergency service throughout the area, including Pointe-Claire, Dollard-des-Ormeaux, Kirkland, Beaconsfield and Pierrefonds.
How much does flat roof repair cost in the West Island?
Cost depends on the extent of damage and membrane type. We provide a free on-site diagnosis and a detailed no-obligation quote — in most cases, a targeted repair costs significantly less than a full replacement.
Can you respond to an emergency leak in the West Island?
Yes, our 24/7 emergency service covers the entire West Island. Call (514) 967-3609 — we'll mobilize a crew to stop the active infiltration and schedule the permanent repair.
Do you work on flat garage roofs in the West Island?
Yes — garage and addition flat roofs are among our most common jobs in the West Island. We repair fatigued membranes, re-flash penetrations and re-waterproof without necessarily replacing the entire roof.
South Shore
Learn More →Do you handle commercial roofing on the South Shore?
Yes, commercial and institutional flat-roof work in Longueuil and Brossard is a core part of our South Shore coverage, including scheduled maintenance programs.
How fast can you respond to the South Shore for an emergency?
We dispatch 24/7 across the South Shore, with crews familiar with bridge access points to reach Longueuil, Brossard, Saint-Hubert and Saint-Lambert quickly.
Can you work on older homes in Saint-Lambert without a full replacement?
In most cases, yes — our repair and waterproofing service is built around fixing what's failing rather than defaulting to full replacement.
Laval & North
Learn More →Do you do new-construction roofing in Laval?
Yes, new-build installation is a significant part of our work in Laval and the northern suburbs, alongside renovation and repair.
Can you repair a flat roof over a garage or addition?
Yes — flat-roof additions and garage roofs are common repair and waterproofing jobs across Chomedey and Laval-des-Rapides.
