How attic ventilation works, why balanced intake and exhaust matter and how poor airflow affects roofs, energy use and moisture.
An attic is a buffer between your living space and the weather. Hot summers bake it, and cold winters cause moisture from the house to condense under the roof. Ventilation brings in cooler outdoor air low at the eaves and lets hot, moist air out high near the ridge. A balanced system helps shingles last, reduces moisture and can make upper floors more comfortable.
Problems arise when vents are blocked by insulation, painted over, mismatched or missing. Too much exhaust without enough intake can pull conditioned air from the house. Insulation and air sealing work together with ventilation. In Nashville, humid summers and cold snaps make attic moisture a real concern. We inspect attics, calculate needs and explain how soffit, ridge and gable vents fit together.
Soffit vents bring air in low at the eaves.
Ridge and roof vents let hot, moist air out.
Baffles keep insulation from blocking airflow.
Poor airflow can cause condensation and rot.
Intake and exhaust should work together.
Better airflow can reduce attic heat.
