Attic Ventilation & Soffit Baffles
A Healthy Attic Is a Cold, Dry Attic
An attic is supposed to stay close to outdoor temperature in winter. Cold air comes in at the soffits, moves up under the roof deck and leaves through roof or ridge vents, carrying away any moisture that got up there. When that airflow is blocked — usually by insulation packed into the eaves — moisture lingers, the roof deck stays damp, and frost and mould follow.
Common Ventilation Problems We Find
Ventilation issues are often created by earlier insulation work or renovations:
- Soffit vents buried under insulation, with no baffles
- Painted-over or solid soffits with no actual intake
- Bath or kitchen fans venting into the attic, or ducts disconnected
- Too little exhaust, or a mix of vent types working against each other
- Crushed or uninsulated fan ducts that drip condensation in winter
How We Fix Attic Ventilation
Check Intake and Exhaust
We look at the soffits from inside and outside, the roof vents, and the fan ducts, and compare what’s there with what the attic needs.
Install Baffles
Baffles at the soffit bays hold insulation back from the eaves and keep a clear channel for intake air.
Vent the Fans Outside
Bath and kitchen fan ducts connected, insulated and run to a proper exterior termination.
Recommend Roof Work if Needed
If the roof needs more exhaust venting, we’ll tell you what’s required so it can be handled by a roofer or at your next re-roof.
