Why Does Roof Ventilation Matter So Much?
Roof ventilation matters because a badly ventilated attic bakes shingles from underneath in summer and feeds ice dams in winter. It also traps moisture, which is how you end up with mold and damp insulation on a roof that never actually leaked. Ventilation quietly decides how long a good roof lasts.
When Does an Attic Have a Ventilation Problem?
An attic has a ventilation problem when frost forms on the underside of the roof deck in winter, or the space is brutally hot in summer. Damp or compressed insulation says the same thing, and so do ice dams that return every year on a sound roof. Shingles ageing far faster on one slope is another sign worth checking.
- Frost on the underside of the deck in winter
- Damp, compressed or moldy insulation
- Ice dams returning every year on a sound roof
What Does Roof Ventilation Work Involve?
Roof ventilation work means balancing intake and exhaust across the attic. Most problem attics have exhaust vents but no working intake at the soffits, so nothing actually moves. We assess what you have, calculate what the attic area needs, and correct both ends rather than just adding another vent.
- Intake and exhaust balance assessment
- Ridge venting sized to the attic
- Clearing or adding intake vents at the eaves
- Sealing attic air leaks from the living space
How Do You Fix a Ventilation Problem?
Fixing a ventilation problem starts by working out the attic's square footage and the airflow it actually requires, which is a calculation rather than a guess. In practice the fix is usually opening blocked intake vents under the eaves and fitting correctly sized ridge venting, so cool air enters low and warm air leaves high. Most attics we look at have exhaust and almost no intake, which leaves the attic pulling air out of your house instead of from outside.
- Measure what the attic needsAirflow requirement comes from the area, not guesswork.
- Check what is really thereBlocked soffits are the usual culprit, not missing ridge vents.
- Correct intake and exhaustBoth ends have to work or neither does.
- Seal leaks from belowWarm indoor air in the attic undoes the ventilation.
