A stove range hood filters out air pollutants and grease keeping your kitchen clean and presentable. Sadly, the same can’t be said if it is dripping. Your range hood could be dripping water in the rain for a number of reasons.
A range hood starts dripping water on a cold day if the insulation on the pipes is worn out. When the vapors inside the exhaust duct come in contact with the cold duct wall, they condense to form water droplets that drip out.
Bad insulation is one of the most common reasons. In this article, we will go into the details of why your range hood starts dripping when it rains and what can be done to resolve the issue.
Why is My Range Hood Dripping with Water
1. Problems With the Roofing and Vent System
Leaks and Cracks
On a rainy day, water is collected on different roof parts. It drips down into the vent system if it finds any leaks or irregularities. This situation worsens in heavy rain as smaller cracks also let water in.
This issue is very common with ducting installed through the roof. However, if you opt for wall ducting, you can eliminate this problem.

2. Problems With the Range Hood
Faulty Exhaust Fan
The smoke and steam produced while cooking is reliant upon the exhaust fan to be pushed out. If the exhaust fan is not working correctly, the air ducts will accumulate a lot of vapors.
Over time, these vapors convert into droplets through condensation which then drips down through the hood filters.
A broken exhaust fan would cause this problem even when it is not raining. However, cold and rainy weather would definitely speed up condensation and aggravate the issue.
Choked Up Filters
Sometimes the answer to your question, why is my range hood dripping water when it rains, is not very technical. If you do not regularly clean the hood filters, the accumulated dirt and grease go up to the pipes and cause blockages.
If the range hood is still working with blockages in the pipes, this will eventually damage the pipes and result in leaks.
It is recommended to clean the hood filters at least once a month. However, the filters might get clogged up sooner if your cooking involves a lot of oil.
Bad Insulation
In order to safely transport smoke and steam out of the house, the temperature in the pipes must remain constant. This is achieved through proper insulation of the ducts.
When the insulation becomes ineffective, the temperature on the outer surface of the duct affects the temperature inside. Thus, on a cold day, the vapors inside the duct become liquid and drip out through the filters.
In addition, bad insulation also makes the range hood noisy as it fails to contain the noise of the working exhaust fan as well as any other sound reaching the ducting system.
