It won’t be necessary to call a handyman in most cases. Some simple DIY solutions can fix this issue for you as they did for me.

Learn what causes this issue before you check the fix! I found two most common causes, which are as follows:

  • Condensation in the duct:

Does water drip over your head when you are taking a shower or right after taking a shower? This problem has troubled numerous homeowners. It’s simply irritating that the exhaust fan starts dropping water drops over your head. Condens inside the duct is mainly responsible for this issue.

If you’re interested, take a look at the condensation stains article.

The exhaust fan tries to release warm air from your bathroom during the winter. That warm air gets cooled quickly as it comes in contact with cool air in the attic and it turns into water drops. Those water drops fall down through the bathroom fan.

You shouldn’t ignore this issue for a long time because your bathroom won’t stay dry. There will be an ideal environment for mold and mildew growth and that’s a serious concern. Condensation in the duct caused a water dripping issue in my shower.

I’m not the only person facing this issue because many homeowners have reported this problem. Therefore, I strongly believe that you are facing the issue due to condensation.

  • Ice buildup on the roof:

Ice buildup on the roof can also cause water dripping issues. Accumulated ice starts melting as it comes in contact with hat shower air and drips into the bathroom. Water will drop over your head if melting ice falls directly over the exhaust fan.

Most of us prefer a hot shower during winter days and water vapor escapes out through the exhaust fan. That hot vapor quickly melts ice over the roof and turns it into tiny water drops.

Those water drops get inside your bathroom and destroy your efforts of keeping the bathroom clean and dry.

Is it a fixable issue? Yes, you can fix this problem easily and we have offered some simple fixes for this problem. So, continue reading to find an effective solution.

Fixing bathroom exhaust fan leaking water

It was my top priority to find a perfect fix when I found that the bathroom exhaust fan leaking water. The toughest part of the entire fixing process is spotting the leak. Water can leak through several areas and you need to check all of them.

Inspect the duct

If the fan duct is equipped with a flap that opens when the exhaust is in action, it can malfunction and cause trouble. The flap might not close completely after exhausting hot air. Cold air will get into the duct and cause rapid cooling of hot air. Consequently, water will drop through the fan whenever it is in the action.

Carefully inspect the duct and the flap. Fix it if it is broken or call a professional to repair the entire mechanism.

You should also check the chimney for the damage when trying to fix water dripping from bathroom exhaust fan. Water can leak through the damaged chimney cover or through a crack in the crown.

How to stop condensation in my bathroom fan?

Bathroom fan condensation occurs mainly due to poor airflow. Clogged vents or low air pressure cannot push hot air out of the vent.

Consequently, exterior cold air gets into the vent and cools the hot air before it escapes. Water starts dripping from the fan and causes moisture and a humid environment in the bathroom.
