How to Keep Rain From Blowing in Attic Vents

Rain that gets into an attic through vents during a storm can result in costly damage to the home. Mold and mildew growth, rotting wood and water damage are among the most common problems that result from rain getting into the attic. While attic vents are designed to keep rain and snow out, there are some tricks to keeping the rain from blowing into the attic vents.

  1. Install turbine vents. During heavy wind and rain, the turbine will spin and knock the rain back rather than allowing it into the vent. Neither snow nor rain gets into the vent due to the spin.

  2. Put up external bracers. Any turbine vent or vent that works in a similar manner to turbine vents can have problems in high winds. External bracers will add extra support for the vent during heavy wind conditions, preventing damage to the vent and allowing the vent to work properly.

  3. Install a hip vent. Hip vents have buffers that keep out the rain and snow from the vent while allowing air to travel through the vent. Not only are they convenient due to the buffers, but they can match the roofing material so that they look like part of the roof.

  4. Add buffering to the vent. If installing the vent system is too costly, adding buffering is another option. Buffering will prevent rain and snow from getting into the attic without requiring a new roof or complete vent replacement.
