Complete roof replacement services for residential properties across Greater Montreal. Full tear-off, deck inspection, and new installation with manufacturer warranties.
When a roof reaches the end of its useful life, a full replacement is the most reliable way to restore complete protection to your home. Roof replacement is a significant investment, and our process is designed to deliver lasting value by addressing every layer of the roofing system, not just the visible surface material. A quality roof replacement starts with a full tear-off of the existing roofing down to the deck, which allows us to inspect every square foot of sheathing for rot, soft spots, and structural issues.
In Montreal, decades of snow, ice, and freeze-thaw cycling take a toll on the entire roof assembly. We commonly find damaged sheathing, rusted flashing, deteriorated underlayment, and inadequate ice and water barrier coverage when we strip an old roof. Addressing these issues during replacement prevents problems from carrying over to the new roof system. We replace any damaged sheathing, install new underlayment, apply ice and water barrier along eaves, valleys, and around penetrations as required by Quebec building codes, and install new drip edge and flashing before any roofing material goes on.
Material selection is a key part of the replacement process. We help you choose the right product based on your budget, the architectural style of your home, performance requirements, and long-term goals. Options range from standard three-tab shingles for maximum affordability to architectural shingles for enhanced durability and appearance, or premium materials like metal or slate for homeowners who want a roof that will last the lifetime of the building.
Our replacement projects include complete site protection with tarps and plywood to protect landscaping, siding, and windows during tear-off. We use magnetic sweepers and thorough manual cleanup to collect every nail and piece of debris. Waste is loaded into dedicated containers and disposed of responsibly. The result is a clean job site and a new roof installed to manufacturer specifications with full warranty coverage.

FAQ for this service
Most residential roof replacements in Montreal are completed in one to three days depending on the size and complexity of the roof. Factors that affect timeline include the number of layers to remove, extent of deck repairs needed, and weather conditions. We plan for efficiency while maintaining quality.
You do not need to be home during the entire process, but we recommend being available at the start for a walkthrough and at the end for a final inspection. The work is performed entirely from the exterior, so interior access is not typically needed.
A new roof can significantly improve curb appeal and remove a common objection from buyers. If your roof is near the end of its life or showing visible wear, replacement before listing can be a strong investment. It also simplifies the buyer's home inspection process.
Damaged sheathing is replaced with new plywood or OSB that matches the existing deck thickness. We replace only the affected sections to keep costs reasonable while ensuring a solid foundation for the new roof. Deck repair is priced separately and discussed with you before proceeding.
In most cases, yes. Switching from shingles to metal, for example, is common during replacement. The main consideration is whether the existing roof structure can support the weight of the new material. We verify structural capacity and recommend reinforcement if needed.
