Inadequate fresh-air intake at the eaves prevents the natural 'stack effect' required for cooling. Without proper soffit venting, your attic traps stagnant, superheated air.

Insufficient exhaust vents at the ridge or high-slope areas prevent heat and moisture from escaping. This imbalance leads to rapid shingle degradation and high cooling costs.

When blown-in insulation is installed without baffles, it often blocks the soffit vents and cuts off intake airflow. Additionally, many homes built before the 1980s have wood paneling behind the perforated soffits that completely restricts ventilation. To fix this, we will cut new soffit louvers to ensure proper airflow into the attic.

Gaps around pot lights, plumbing stacks, attic hatches, and interior wall top plates allow warm, moist air from your living space to enter the attic continuously. No amount of ventilation can compensate for an unsealed thermal boundary — the moisture source must be addressed through air sealing before ventilation can perform correctly.
