How to Clean Soffit Vents

Proper air flow in and out of your home's attic is essential for heating and cooling efficiency. Outside air flows into the attic by way of the soffit vents on the roof's overhang. The outside air pushes the air in the attic out of the roof vents. A potential problem with soffit vents is that they can become clogged with debris. It is important to remove the debris so that air flow will not be restricted.

Set up a ladder near a soffit vent.

Turn on your air compressor and hold the end of the hose approximately 3 inches from the soffit vent. Press the trigger on the air hose to release the compressed air into the vent.

Point and release compressed air into all areas of each soffit vent. The blasts of air will blow any debris or insulation out of the way and clear the vent. Repeat once or twice per year.

Things You Will Need

  • Ladder
  • Air compressor with hose


  • Hook up the hose from your shop vacuum or leaf blower to the exhaust port on the appliance to substitute for an air compressor.


  • Wear safety goggles and a dust mask.
  • Don't attempt to clean the soffit vents with suction from a vacuum. The debris must be blown upward for effective removal.
