Buying Guide

Size of your roof vent

The general size of a RV roof vent is 14 inches by 14 inches. But if you plan to replace an existing fan, check if the new one will be able to fit the existing hole. If not, you may need to cut a bigger hole.


You can measure the garnish, which is the piece that trim piece that covers the vent opening. Also check if your garnish is the right height by measuring your roof’s thickness. Know that RVs with air conditioning tend to have thicker roofs. 

Opening method

There are 2 types of opening lids. The first one requires you to manually open it,  and the second can be opened automatically. If it is difficult for you to reach your ceiling to open the vent, you may want to consider a fan with a remote. 

However, in general, for most RVers, manual openings are found to be sufficient for when choosing an RV vent.



If you are full time RVing, this may be an annoyance if your fans are humming loudly due to the fan blades or the motor. Don’t forget the reason you are RVing is to get peace and quiet.

CFM rating


CFM “Cubic Feet Per Minute” is an indicator used to measure the amount of air per minute that your fan can remove. A higher CFM rating is more effective in removing moisture and heat from your rig at a faster rate. This also means, they may draw higher amperage when running. The minimum CFM you should be looking at is 900, if you have a class A rig.

Ease in installation


When removing the RV vent, you may need to remove the seam tape or roof sealant around the edges of your vent. Then after you have installed it, you need to reseal the edges to ensure the RV roof is sealed watertight.


If you are RVing full time or always RVing in summer, you may want to get one which is higher quality. 

Some RV roof vent comes with RV roof vent covers. Having Metal lids as RV roof vent covers are great choices as they can withstand hail storms or the scorching sun.  And it cuts off the sunlight when it is too bright.

RV vent covers are usually made in a dome size and generally have a higher height. This allows the water to stream down, preventing ice from forming. At the same time, it saves you electricity as you need less lighting as its transparent cover allows light in.

Additional options

Some RV Vents may even have a sensor that helps to detect the temperature in the rig and automatically turns on the fan when required.

There are also RV vents that come with built-in covers so you do not need to purchase a separate vent cover.

What are RV Roof Vents For?

If you plan to leave your pets in your RV, then having a RV fan keeps them from overheating. This is because your RV can heat up very quickly especially in summer. 

In winter, it helps keep the moisture out as condensation can become a problem if you live in a confined space. If you are looking on how to keep out moisture out of an RV, I recommend you check out our guide.

Having the RV roof vent helps to bring in the fresh air to replace your stale air and eliminates odors especially from your RV toilet. If you cook a lot on your RV stove, it helps to vent out the smoke from your trailer.

Enabling your RV to breathe, also helps to slow down your interior from breaking down.
