Why Attic Airflow Matters

In a well-ventilated attic, natural air flow moves super-heated summer sun from the interior of the attic to the outdoors, protecting roof shingles and removing excess moisture. This uninterrupted airflow cycle also helps prevent heat and moisture from transferring into living areas of the house, saving on energy costs.

Proper attic insulation contractor requires both intake and exhaust vents positioned in the attic space to provide proper high-low balance. Intake vents are most often found in the form of soffit vents, which allow cool outside air to enter the attic. Then, as the air warms up, it rises and exits through exhaust vents positioned near the roofline’s highest point. Exhaust vents need to be properly sized for optimal performance and positioned with adequate spacing under the eaves to ensure they can operate without being blocked by shingle debris or excessive insulation.

Insulation doesn’t directly improve attic ventilation, but it does work in tandem with it by slowing down the natural convection that continuously migrates heat and moisture through walls, ceilings and into the attic space. Well-insulated homes with well-functioning ventilation systems will not only save on energy costs but will prolong the life of the home’s building materials and reduce the load on a heating or cooling system.

How Quality Insulation Helps Cut Your Energy Bills

An easy way to test whether your attic ventilation system is working is by observing the temperature of your attic space on a warm, sunny day. If the attic space feels significantly hotter than outdoor air, then your ventilation system is not functioning properly and needs to be corrected.
