An investment for years to come
A roof replacement means removing the existing covering when necessary and installing a complete new system: underlayment, covering, flashing and ventilation.
It's for homeowners whose roof is reaching the end of its life, has repeated leaks or needs increasingly frequent repairs.
Signs it's time to replace your roof
- Ageing materials
- Recurring leaks
- Significant shingle deterioration

Which type of roof should you choose?
For sloped roofs, asphalt shingles are the most common choice in Quebec, balancing protection, appearance and cost. For flat or low-slope roofs, an elastomeric membrane is a widely used solution.
Other systems may suit depending on the roof design. We'll recommend the option that fits your building.
How much does a roof replacement cost?
There's no single price: every roof is different. We'll help you get a clear quote, suited to your needs and your budget. The main cost factors are:
- Surface area
- Slope
- Materials
- Roof complexity
- Accessibility
- Condition of the existing deck
- Ventilation and drainage requirements
When is the best time to replace a roof?
Spring, summer and fall offer the most favourable conditions, partly because some materials bond better in mild weather. These are also the busiest periods, so planning early helps secure the dates you want.
Replacement is still possible in colder weather with the right precautions, especially when the roof can't wait.

FAQ
What homeowners ask us
How long does a roof last?
It varies with the material, installation quality, ventilation and exposure. As a guide, an asphalt shingle roof often lasts 15 to 30 years depending on the product line, and a well-installed elastomeric membrane can last several decades.
How much does a roof replacement cost in Quebec?
Cost depends on surface area, slope, materials, roof complexity, access and the condition of the existing deck. An on-site assessment is needed to give you a reliable price.
How long does the work take?
For a typical single-family home, the work often takes one to a few days. Weather, size and deck condition can extend that.
Can a roof be replaced in winter?
Yes, with cold-weather precautions and depending on materials. Conditions are more demanding, and the work is scheduled around the weather.
What's the difference between repairing and replacing?
A repair fixes a localized problem on a roof that's still in good condition. A replacement renews the entire system when materials are worn out or problems are widespread.
How do I choose the right materials?
The choice depends mainly on roof slope, then on budget, desired look and expected lifespan. We'll present the options suited to your building.
