Bathroom Exhaust Fan Leaking Water In Rain?

One of the problems that often haunts the homeowners is the bathroom fan leaking after heavy rains.

The leakage is noted even when there is slight rain pouring in. The overall chaos gets serious if the problem is not addressed well in time.

Here I have collected all the information required to identify and then deal with leaking bathroom fan.

Why The Bath Fan Leaks?

The bath fan leakage is due to several reasons. One single reason cannot be quoted regarding the leakage.

Here are a few things that you need to check if your fan is leaking during or after the rain.

The Vertical Slope

One most common reason that leads to the leaked fans in the bathroom is the vertical slope of the bath vent hose.

In many cases, if the exhaust is resting on the top of the roof, the fans might show leakage signs.

In case the vent is not installed correctly, or there is a problem with the covers, the rainwater will start tripping from the fan into your bathroom.

The vent can also develop mold, structural damage, and termites due to the moisture coming in. All these factors would further cause leakage and tripping.

The Vent Covers

Damaged damper or vent cover can also cause leakages. The moment you see the fan leaking, it is a sign of the vent cover’s damage.

The faulty damper permits the water to the dropdown. This issue usually arises when the cover is not placed firmly.

The moment the damp gets loose or gets missing, the fan would start leaking.

The job of the vent is to allow the hot air to escape outside. It is the pressure of the air that opens it. In other cases, it remains closed.

In case this mechanism is not functioning regularly, the damper must be removed immediately.

The Faulty Seals

The seals can stop working after some time. The homeowners often complain about the expansion and cracking in the seals.

This faulty situation lets rainwater drop down into the bathroom through the fan.

To avoid the problem, a better sealant can be added or otherwise replacing the vent itself can be helpful.

How To Check?

If there is some problem with the fan in the bathroom, don’t make assumptions. To find a solution, it is essential to check carefully what is leading to all the chaos.

You need to investigate some necessary things before either correcting them on your own or calling a professional.

#. Have a look at the vent cover. The problem usually arises when the vent cover is not working correctly. Check closely all over the vent cover.

Don’t ignore even the tiniest crack. The point where the vent meets the roof must be investigated carefully. The best way to cater to the defected cover is to get a new vent.

#. Shingles play a pivotal role in the bathroom fan operation. They look like minor accessories, but they have a significant role to play.

Check for the health of the shingles. If the shingles are not properly working, then it means that the rainwater is finding room to move down through them.

#. The next step in the investigation involves checking the vent flap. If it is not operating the usual manner, the rainwater will drip down.

Replace the flaps with a new one that can resist the changes going on. The experts suggest root caps made with powder-coated galvanized steel can be effective.

Is The Rainwater Leakage Risky?

The rainwater dropping down from the fan would damage the interior of the wall, but it can cause the risks that are harmful to health.

The attic, inner wall, and the ceiling cavity are dark spaces. As the moisture keeps dripping down, the humidity can cause molds and mildew.

They can result in spores that can be a real health hazard.

Finally, Seek Professional Assistance

Don’t ignore the first sight of leakage from the bathroom fan. It is not merely a mess in the bathroom but can get extremely scary for the residents.

The leaking water can result in molds and damage to the interiors, especially the ceiling and the walls.

Tracing the cause of the leakage becomes a must after witnessing the first signs of leakage.

To save your home from any unwanted outcome, it is essential to resolve the issue as soon as possible.

Therefore, call a professional assistant to help you in settling the leakage.
