Flat Roof or Sloped Roof, Which One to Choose for Your Building in Gatineau?

Planning a new build or major renovation? Choosing your roof type is crucial — both for style and long-term performance. Should you go for a modern flat roof or a classic sloped roof?

At Trinic Toitures, we install both types across Gatineau and the Outaouais, for residential and commercial projects alike. Here’s a simple guide to help you decide.

The Flat Roof: Modern, Functional, and Practical

A flat roof isn’t perfectly “flat” (it has a slight slope for drainage), but it offers a horizontal surface with many benefits.

Advantages:

Modern architectural style
Perfect for contemporary homes, multiplexes, or commercial buildings.
Space usage
Can be turned into a terrace, green roof, or solar panel space.
Easy access
Convenient for maintenance, inspections, or mechanical installations.
Simpler, more economical construction
Requires fewer structural materials than a sloped roof.

Considerations :

Waterproofing must be flawless.
Snow and water buildup require more regular seasonal upkeep.

The Sloped Roof: Classic, Efficient, and Durable

This is Quebec’s most common roof type, especially for homes. It naturally sheds water and snow, making it well suited to our climate.

Advantages:

Excellent drainage
Lower risk of leaks or water buildup.

Longer lifespan
Proper attic ventilation helps avoid moisture issues.

Wide range of materials
Asphalt shingles, metal, wood shingles, tiles, etc.

Timeless style
Ideal for traditional or country-style homes.

Considerations :

Less accessible for maintenance.
More complex to design for modern architectural forms.

Which is right for your Gatineau project?

Residential:

Contemporary homes → flat roof.
Traditional or country homes → sloped roof, especially in heavy snow areas.

Commercial/industrial:

Flat roofs are generally preferred for ease of use and maintenance.
