If you’re a shed owner, then you may be wondering if your shed needs ventilation. After all, it’s not like your house where you have things like plumbing and electricity running through it. So does your shed really need to be ventilated?
Sheds need ventilation. Usually, the air inside a shed will be warmer and more humid than the air outside, which can cause problems like mold and mildew. Vents help by drawing fresh air into the shed and exhausting stale air out. Good ventilation also helps prevent fires.
If you are looking for a full guide on shed ventilation, including a guide on the different types of shed ventilation, how much ventilation is needed, and where to put it, then keep reading to learn all you need to know.
Do Sheds Need Ventilation
You may have heard that sheds need ventilation, but do they really? The answer is yes – sheds do need ventilation to keep the air circulating and to avoid moisture build-up. Without proper ventilation, your shed can become a breeding ground for mold and mildew, and it can also cause the wood to rot.
There are several ways to provide ventilation for your shed. One option is to install a window or door that can be opened to allow air to circulate.
You can also install a roof vent, an exhaust fan, or roof soffits and gables.
Whichever method you choose, make sure that the openings are large enough to allow adequate airflow.
Where should shed vents be placed
It’s important to place your shed vents in the right spot to ensure good air circulation.
You’ll want to place them high up or even on the roof or in a location where the air can flow through the shed easily.
One source of ventilation is ok and will work for smaller sheds. Two sources of ventilation, one placed at each end of the shed, will ensure cross ventilation and keep the air flowing.
Vents placed too close to the ground will not work as well, so be sure to place them high up on the shed.
How Much Ventilation Is Necessary
The National Building Code recommends 1 sq. ft. (144” sq.) of venting per 300 sq. ft. To find out how much ventilation you’ll need, multiply the length by the width of your shed and then divide it by 300. A shed that is 300sq ft or less, will require one sq ft vent.
Finding the right ventilation requires balancing your air intake and exhaustion. Too much intake and there will be a lot of moist air that lingers in your shed for long periods of time. Too much exhaust may cause hot air to be pulled back into your shed and may even bring moisture into your shed when there is a downpour.
Most sheds can be properly ventilated with simple gable louvered vents or turbines, so there are easy and inexpensive ways to ensure that your personal belongings are not at the risk of mold, dry rot, or exposure to harmful toxic chemicals over a long period of time.

- If your shed is between 300 and 600 sq ft: Install two of these gable louvered vents

What Are Common Issues Caused by Sheds with Poor Ventilation
Many people do not spend a lot of time in their shed because most sheds are made specifically for storage purposes, so we often do not consider the dangers of toxic air quality. While a certain familiar smell can be friendly, toxic gasses from paints, oils, and other materials in a shed may cause health problems if you are exposed to deadly gasses for too long.
Take a look at some of the common issues that you may run into if you do not properly ventilate your shed:
- Stale Air – This may be the most obvious telling sign that something is wrong because when your shed is suffering from stale air, there will be a discernable unpleasant smell that starts to invade all items and make them smell unpleasant. This may cause short-term respiratory pain and eye irritation.
- Harmful Chemicals – If you are storing items such as gasoline, pool chemicals, fertilizers, and other items that may cause noxious gasses, you may want to consider checking your ventilation system. Poor ventilation systems with these chemicals can result in respiratory issues, eye irritation, skin irritation, and you run a higher risk of flammable gas being extremely explosive in tight spaces.
- Excessive moisture and Condensation – Moisture may cause mold and mildew to grow, causing long-term respiratory problems, headaches, and damaged personal belongings. Condensation may cause wood to rot, metals to rust, and mold to grow with excessive moisture build-up.
- Heat – Working in your shed can be extremely uncomfortable in the heat and may eventually cause respiratory issues. Some personal items may not be able to withstand the heat within the shed.
- Cold – It may be very uncomfortable to work in your shed in the winter months, and without a vapor barrier, you may be exposing yourself and your personal belongings to harsh conditions that may cause harm.
We looked at, do sheds need ventilation? We learned that keeping your shed properly ventilated is essential in maintaining not only your shed’s health but your health and the health of all of the personal items you are intending to store.
