If you have a trailer, you are one of those lucky ones who can set off and travel all years round if they feel like doing so!
Recreational vehicles allow us to move around and visit new places, and they are definitely more comfortable than traveling tents!
However, if you want your trailer to remain the same cozy and warm (and dry!), you need to make sure that you maintain its roof properly.
This is why an issue of resealing your travel trailer’s roof may become a point of concern for many.
And in case you realize that it is time to reseal your camper’s roof, this article will be very useful for you.
It will tell you how often the procedure of resealing should be done to keep your recreational vehicle in a good state.
Also, you will learn why this is needed at all, and how this should be done step by step.
Finally, we will tell you how much you might pay for that, and how you can figure out that your trailer’s roof is in need of resealing.
How Often Shall I Reseal My Trailer’s Roof?
If you have faced your travel trailer roof sealing issue recently, you might also be asking yourself how often this procedure should be done.
Well, if you want to keep your trailer’s roof properly sealed and avoid any leaks, you need to consider resealing it once a year annually.
Like this, you will make sure that the roof is in a good state and you will also avoid not only leaks but even extend the lifespan of the entire trailer!
In addition, except for regular resealing of the camper’s roof, it is also recommended that you check the roof for leaks and sealant deterioration.
This should be done twice a year at least. It will help you to skip any mishaps that may come with the roof issues.
And please remember that without a properly sealed roof, recreational vehicles are way more prone to leaks, further degradation, and thus expensive repairs.
A proper and in-time reseal will prevent all this from happening, and keep you on the road in your trailer longer.
Now, we guess, you might be wondering how the sealing/resealing procedure should be done correctly, and whether it is ok if you do it yourself. Well, let’s figure this out!
How to Reseal a Travel Trailer Roof
If you know for sure that it is time for resealing your travel trailer’s roof, but you realize that it is way too pricey for you to handle it to the professionals, the only way out is to do the job yourself!
You might be wondering how to reseal a camper roof in this case. Well, luckily, the process is rather simple. You will just need some patience and time.
Follow the steps below precisely, and your camper roof will be like new again pretty soon!
- Remove old seals. We recommend you never skip this phase since, if you apply the new sealant on top of the old one, old cracking and crumbling sealant will not provide a smooth and solid surface for the new product to adhere. As a result, you will have the same leaking roof that you were striving to avoid.
- Remove an old sealant when replacing corner seals or the seals around the doors and windows. On the roof, just remove all crumbling and cracked sealant in order to provide a good foundation for the new stuff. In many cases, removal of the side seals requires using a razor blade. However, the seals on the roof should be removed with the use of something a bit more blunt (e.g. a putty knife) because the rubber roof can easily be cut and damaged.
- Clean the roof after you remove the old sealant. Use denatured alcohol to get rid of dirt and debris, as well as of any old sealant’s residue.
- Apply the new sealant following the instructions in order to ensure the end seals are of the best quality. Usually, this means cutting the tip from a tube of Pro Flex (or similar) and applying a bead of sealant to all seams on the sides of the RV using a caulk gun. You will also need to take care of the roof seams with lap sealant using a caulk gun and making sure to cover the seam itself, as well as the space on either side, completely.
- Use salty water to apply it onto the side seams of your RV. All you need to do is to dip your finger into a cup of water with salt, and smooth out each bead of sealant. This helps the finished product look clean and evenly applied.
As you can see, there is nothing difficult about it. Of course, it might take you some time, especially if you’re doing it for the first time, but in general, anyone can manage that task!

Why to Seal Travel Trailer Roof
Of course, some of you, our dear trailer owners, may be still curious about why you should consider sealing your camper’s roof.
Naturally, the most obvious answer will be that once your roof starts leaking, it will quickly become your worst nightmare as a travel trailer owner!
Even the smallest holes in the roof of a camper can lead to quite significant damage and expensive repairs in future.
Because of this, it is strongly recommended that trailer owners regularly check the condition of their campers’ roofs, and have them sealed at least once a year.
However, this is not the only reason why you should bother about that. It may only seem that the reason is so easy and leaks can cause damage to the roof and the inside of the camper.
Nevertheless, you definitely know that leaks tend to appear because of different reasons! Below, we have listed some of the most common causes of roof leaks in a travel camper.

The Roof Is Damaged
This is the leading cause of a roof leak in fact. If there is any damage to the roof itself, you will sooner or later end up with it being leaky.
Why could that happen? Well, mother nature loves playing tricks on us sometimes!
Falling tree branches, strong winds, or sustained weight on the roof can all be examples of where that damage could come from and be followed by a roof leak.
The Sealant Is Faulty
You are surely aware that many of the pieces that are located on the roof of a trailer, such as the air conditioner or vents, are sealed with the use of a sealant system.
However, over time, and while being exposed to the elements (e.g. rain, snow or wind), these sealants can wear down or even dry up.
When it happens, the sealant will then pull away from the seam thus leaving cracks and spaces for water to get inside.
Aging
Time has no mercy both for humans and for our trailers! As the age of a trailer gets advanced so will the issues that occur over time. Things will not work as well as they used to when the camper was just bought.
Also, the seal might not work to the same ability as it did on a new model.
An aging roof of a travel camper can decrease its effectiveness to keep out water over time, regardless of care or maintenance.
Loosened Screws
There are a couple of things that can be screwed into the roof of your trailer, such as the access ladder, the air conditioner, and the screws holding the pieces together.
With time, these screws can loosen their hold and create enough space for water to pass by and enter the interior portions of your roof.
As you might already guess, these were just the most common reasons for why leaks might appear on your trailer’s roof.
This is why regular check ups to inspect the current condition of your travel trailer’s roof, from both the inside and the outside, is essential in order to catch these leaks before they happen or progress too far.
How to Know That Resealing Of Your Camper’s Roof Is Needed?
All right, you may say. Now we know why sealing is needed, and how often it should be done.
But how do I know that the roof of my camper needs that procedure? Are there any visible signs?
Or shall I just wait until water starts dripping right from the trailer’s ceiling?
Of course, you must not let it happen! The roofs of travel trailers are typically made out of different materials, such as rubber, TPO, plastic, aluminum and fiberglass.
So even before you do anything to the roof, we would suggest you check out your owner’s manual in order to figure out which material exactly is present on your very model.
It will allow you to find the best way to care for the roof that you have.
And of course, you need to know the face of your “enemy” which means that, during the regular roof check ups, you should know for sure what you are looking for when searching for any flaws.
It will allow you to easily recognize the signs that show you the roof is in need of a reseal.
Also, remember that you must be very careful while you are on the roof of your trailer!
Not all roofs are designed to hold the weight of a human on top!
So if your trailer does not have an attached ladder, this most likely means that you should not take a risk and climb on top. Instead, you want to use a personal ladder to move it around the perimeter of the roof during your examination.
So what exactly should be done in order to spot any flaws? First of all, inspect all the seams closely for any areas that may look like they are separated from the trailer.
You can also use a small tool, such as a screwdriver or a plastic scraper, to poke the sealants.
It will help you to test it for elasticity. If it gives under the applied pressure, and returns to its original state, the sealant is still in a good condition.
These are the most noticeable ways to tell if a trailer needs to be resealed.
How Much Does Sealing Of a Travel Trailer’s Roof Cost?
Surely, if you have to check the roof of your trailer once a year and do check ups at least twice a year, you might be wondering how much it might cost you.
Here you need to know that, as with the majority of services that need to be performed regularly on a travel trailer, the service of sealing or resealing the roof is typically provided by most professional shops.
In this case, the job will be done much faster and definitely more effectively than if it is done at home by yourself.
However, if you decide to hire professionals to deal with your trailer’s roof, you might be rather concerned about the price.
The cost of having a professional reseal of your trailer roof will usually depend on a few factors:
- the length of your trailer
- the materials your roof is made of
- the amount of labor intensive work involved
On average, a roof reseal for a travel camper might cost you in the range of a few hundred dollars up to a few thousand!
But if this is way too expensive for you, sealing the roof of a camper is the sort of task that can relatively easily be done by yourself.
To do it, you will not have any special skills or expensive tools.
And of course, it will be a much cheaper alternative!
How to Reseal a Camper Roof Step By Step?
All right, so if spotted water in your RV and you realize that it’s the leaking roof that is the reason. What’s next? Next, you need to reseal it! If you have never done this before, don’t stress out!
The process of resealing your camper’s roof is pretty simple. Just make sure that you get ready properly, and you follow all the instructions given below precisely. And you will surely succeed!
Get Ready For the Procedure
It is important to not only undergo the resealing process correctly. You should also take care and make sure that you will be safe while doing it. Why is that? Well, because, in order to apply the sealant, you will have to get onto the roof of your camper!
This is why before you begin, we recommend you check your RV manual to see if your roof is intended to support a person’s weight.
If not, you’d better place a ladder as close to the side of the trailer as possible and carefully climb up until you can easily work on the leaking skylight without leaning too far.
Remove the Caulk
Using a putty knife, scrape off the existing caulk that is surrounding the skylight.
By removing the caulk, you will take some pressure, but make sure you don’t press hard enough! If you do so, it might damage the screws or rivets that hold the skylight accessory in place.
Clean Up the Skylight
After the caulk is mostly removed, pour a small amount of paint thinner or mineral spirits onto a cloth or soft brush and rub any residue off from the original putty.
Remember the simple rule of thumb: the cleaner the skylight of your camper is, the better the replacement caulk will be able to adhere to the surface.
Apply the New Caulk
Now it is time for the new sealant application finally.
- Insert the tube of roofing cement into the caulk gun, facing its pointed nozzle away from the trigger gun.
- Cut off the tip of the nozzle with a sturdy pair of scissors or a utility knife.
- Apply a ring of caulk evenly all the way around the seam where the metal or plastic flanges of the skylight meet the roof of the trailer.
- Make sure the caulk completely covers any gaps between the flange and the roof skylight.
At this point, it is not necessary to pump the putty gun continuously. We would rather say, you will be able to produce a more uniform flow if the trigger is pulled at constant pressure until no further pressure can be pressed.
Done! Now the new sealant is applied. See, it is very simple and does not require any special skills or experience from you.
