Ottawa Roof Ventilation
Proper roof ventilation is essential to protect your home from moisture damage, reduce energy bills, and extend the life of your roofing system. At Bart’s Rooftops, we specialize in professional roof ventilation installation tailored to Ottawa’s climate, ensuring your attic stays dry, energy-efficient, and well-protected year-round.
The Importance of Roof Ventilation
Ottawa homes face extreme seasonal shifts—from humid summers to frigid winters. Without proper ventilation, your attic can become a breeding ground for mold, mildew, condensation, and ice dams.
Poor roof ventilation can:
- Cause shingle deterioration and roof leaks
- Lead to high attic humidity and mold
- Trap hot air in summer, increasing A/C costs
- Create ice dams in winter that damage gutters and eaves
Proper ventilation helps control attic temperature, extends the life of your roofing system, and improves your home’s energy efficiency year-round.
Our Roof Ventilation Services
Ridge Vent Installation
Installed at the peak of your roof for continuous airflow. Ideal for shingled residential roofs.
Soffit Vent Upgrades
Allow cooler outside air to enter through the eaves, balancing air movement and reducing attic heat.
Gable Vents
Mounted in exterior walls, ideal for gable-style homes. Help push hot air out of the attic efficiently.
Box Vents (Static Roof Vents)
A low-profile, no-power vent that allows hot air to escape from the attic. Ideal for asphalt roofs and Ottawa’s freeze-thaw climate. Durable, quiet, and low maintenance.
Roof Ventilation Audits
We assess your current setup, airflow balance, insulation, and signs of moisture damage—then recommend precise upgrades.

Frequently Asked Questions About Roof Ventilation in Ottawa
Common signs of poor ventilation include high attic temperatures, musty odors, mold growth, peeling paint, and ice dams in winter. We offer attic inspections to assess airflow, insulation, and venting balance.
Box vents and ridge vents are ideal for Ottawa’s climate because they perform well in cold temperatures and require little maintenance. Powered attic fans and turbine vents may be used depending on your roof design and ventilation needs.
Yes. Proper ventilation reduces heat buildup in summer and moisture accumulation in winter, making your HVAC system more efficient and helping you save on energy costs year-round.
Not always. We can add or upgrade vents without replacing the entire roof—especially if your shingles are still in good condition. We’ll inspect your attic and roof to recommend the best solution.
It depends on your attic size, roof slope, and existing intake vents. Building code recommends 1 square foot of ventilation for every 300 square feet of attic space (balanced between intake and exhaust). We’ll calculate exactly what your home needs during our inspection.
Turbine vents can work in Ottawa, but they’re more prone to freezing or seizing in extreme cold. We typically recommend static box vents or ridge vents for long-term reliability.
