In BC, ventilation also intersects with coastal moisture, seasonal weather change, and the way different roof designs move air.
Why ventilation matters
Ventilation helps the roof assembly dry and reduces the chance that heat and moisture become trapped in the attic or roof cavity.
That affects both roof performance and the health of the structure below.
What a balanced system needs
A balanced ventilation approach depends on intake, exhaust, and a roof design that actually lets air move the way it should.
During roofing work, ventilation details should be reviewed as part of the full system rather than treated as an afterthought.
✓ Intake and exhaust working together
✓ Ventilation matched to the roof design
✓ Moisture control built into replacement planning
When to review ventilation during roofing work
If you are replacing a roof or dealing with moisture-related issues, it is a good time to connect the conversation to roof ventilation support and roof replacement planning.
That gives you a chance to address airflow and waterproofing at the same time.
