What is a Caravan Roof Vent?

Caravan roof vents are very simple inventions which help to ventilate your caravan and maintain good airflow. AS their name suggests they’re usually placed on the roof of your caravan, and they can swing upwards from the roof surface using a hatch.

Normally your vent will have a crank handle so you can control it from inside of your caravan, so once it’s installed, it’s unlikely you’ll need to go back up on the roof regularly. However, some models open automatically when the temperature reaches a certain level whereas some will have electric movement, so you just press a button, and it opens/closes.

The vents have a durable exterior which stops animals trying to sneak into your caravan from above. You’ll be surprised at how many bugs and flies try to get in.

The main purpose of a caravan vent is to keep moisture, bad smells, and other nuisances out your caravan. This will ensure that you can have a better experience in your caravan and your days won’t be spoiled by great weather because these should be the most enjoyable days!

Types of Roof Vent

Roof Vent

This is a standard type of roof vent that you can manually adjust the opening to increase or decrease airflow, or some models have a fixed opening that doesn’t allow you to adjust. This type of roof vent is what is usually found on caravans, especially older models but once installed it doesn’t require additional electricity to run.

Roof Vent Fan

This is an improvement on the traditional caravan roof vent as it has a thermostat and inbuilt electric fan that allows you to control the temperature or speed of the fan so you can quickly adjust the ventilation in your caravan.

This requires an electricity source to power the fan so can incur extra costs which will vary based on how much energy you use. Whether you need a fan will depend on your personal needs, i.e. if you’re travelling around extremely hot countries a fan may be more useful.

Buying Guide


You need to ensure that you understand the size of your existing roof vent so you can choose one that closely fits. The last thing you want to do is end up buying a roof vent that’s too small or large.

Of course, if you’re installing from scratch to a caravan that hasn’t had a vent before then, you have more flexibility about the size that you choose. The price can vary depending on the size of your vent, so you need to take this into consideration.

Ease of Installation

Before buying, you should understand how easy your desired roof vent is to install to your existing caravan. Ideally, it should come with clear instructions and all the necessary parts and screws needed to complete the installation from start to finish.

This will also depend on whether you intend to complete the installation yourself or hire a professional to do it. You can see how easy a vent is to install by looking at customer reviews from previous purchasers to understand if they had any issues with the product, so you aren’t hit with any surprises once you receive it.


Caravan roof vents can vary in price due to several factors. The brand plays a big role because there will be more premium brands than others and use higher quality materials. We’d recommend that you stick with the caravan brands because they have specialised in making products for caravans and have the greatest level of customer service.

It’s also recommended that you have a budget in mind for your caravan vent purchase due to the large range of pricing. Having a budget will also make it simpler to make a buying decision because it will lower the amount of choice available to you. It’s often better to spend a little bit above your budget to get a better quality product that will last longer.


The material of your vent is something to consider because ideally, you should aim to have a vent that is made of durable material. This can

be plastic or metal; however, plastic is recommended because not only is this tough but it’s also lightweight, so it makes it easier to crank up and down when you want to open or close it.

Plastic roof vents often have mesh designs which stop unwanted bugs and animals from flying inside your caravan.

Benefits of a Caravan Roof Vent

Vents are seen as optional, but we think every caravan owner should have one because of all the benefits that it brings.

The most obvious benefit is that it can drastically reduce the temperature throughout the hot summer months, where even in the UK it can be difficult to be indoors if there’s no air circulation.

The additional main benefits of a caravan air vent are all health and wellness related. Over time a musky smell can develop in your caravan, but because you’re living in the environment, you might not even realise as your body gets used to it.

This bad smell can worsen and can be an indicator of mould development and can also affect your health, leading to respiratory implications such as asthma and allergy developments.

It helps to prevent mould build-up because it removes moisture from inside your caravan. If you dry your clothes indoors, then the fresh air will slow down this moisture build-up.

With a roof vent, fresh air can be drawn into your caravan and prevents the build-up of stale air
