Why Attic Airflow Matters

It seems counterintuitive to add insulation and venting in order to keep the attic cold, but it’s actually a crucial part of any energy-efficient home. The ideal combination of tight sealing and proper ventilation regulates temperature fluctuations in the living spaces below and prevents moisture damage to the roof and gutter system.

Ventilation Insulation Contractor attic temperatures, which in turn reduces air-conditioning costs, protects shingles and other roof coverings, and minimizes the possibility of ice dams. It also helps to remove excess moisture from the living space below, preventing mold and mildew.

How to Enhance Attic Energy Efficiency Before Winter Hits

Proper attic ventilation relies on the natural process of convection, which draws warm air to the cooler edges of the house. However, many homeowners have faulty or blocked vents, and it’s critical that all attic ventilation systems be properly sized and installed in order to work effectively.

For most homes, the best solution is a balanced approach that includes both soffit venting and powered attic ventilators. Ideally, there should be one square foot of net free ventilating area (NFVA) for every 300 square feet of attic floor space. It’s important to consult your local building codes for specific requirements.

Intake vents, typically positioned at the soffits or eaves of the house, allow fresh air to enter the attic through the ridge and roof ridge. This air, along with the heat and moisture that are trapped in the attic, escapes through exhaust vents, usually rafter vents or roof louvers, at the top of the attic near the ridge.
