How to Seal a Camper Roof: Get Ready for the Next Camping Trip

The next camping trip is coming up and you need to make sure your camper roof is sealed before you hit the road. You want to get that sealant on there so it will last throughout the entire season.

It’s important that you know how to do this correctly, or else everything could go downhill fast!

Read this blog post for some helpful tips about how to seal a camper roof and get ready for your next adventure.

How to Seal a Camper Roof?

Preparing the Roof

Before you even start thinking about going to buy that sealant, there are a few things you need to do. The first thing is to clean off your roof.

Even though all those grime and dirt marks on it don’t look too bad now, they’ll come back to haunt you if you don’t take care of them before applying sealant. 

You want to make sure all those stains disappear so the sealant has nothing in its way when it’s time for application.

Next step: consider adding insulation. That rubber is not very porous, which means it doesn’t absorb heat well (which isn’t good if your roof gets hot).

If your camper roof is insulated properly, then this will help it stay cooler throughout the summer months and you’ll be able to enjoy your camper more.

Getting out the Rubber Cement

Now that everything is cleaned, let’s think about all those rubber seams. It used to be that you couldn’t do much with these areas except to shine them up with some Armor All or something like that. 

Well now there’s Rubber Cement. It comes in a small can and it allows you to wipe it on any of those rubber seams and create a smooth finish after only one hour has passed by (which means no mess).

Make sure not to get this product on anything but the roof – we don’t want damage!

Let it Dry

Now that you have those rubber seams covered and the entire roof is coated with Rubber Cement, let it dry for one hour. This will give time for any excess glue to harden so it won’t peel off along with the sealant later on. 

It should look nice after an hour has passed by, but there could still be some globs of dried glue on your camper roof. No problem – just leave them alone. They’ll come off with the rest of everything during application of the actual sealant itself (that’s right, no more Rubber Cement until next time).

The Actual Application

Great! Now you’re ready to actually use the stuff that will keep your camper roof protected.

All you need to do is shake the can well, then rotate the nozzle so that it’s pointing towards your camper roof. Apply the sealant in small areas at a time (work in about 6 square feet or so) and let each section dry for 15 minutes before moving onto the next one.

You should go back over everything once more after an hour has passed by just to make sure all areas are completely coated.

Turn the nozzle of your sealant back into its locked position when you’re finished, because you won’t need it again for a long time (maybe never again, if you do everything right).

That’s it! You did it! It may take a little while to go through all of this work, but the end result is definitely worth it.

Your camper roof will always be protected and your family will feel safe and sound every time they’re in the great outdoors!

Step by Step Guide

Knowing what you need to do, and how to do it, is half the battle. If you want to seal a camper roof correctly so that your camper lasts throughout the next season, read this blog post for some helpful information about each step in order to get that job done quickly and efficiently.

Step 1: Clean Off Your Camper Roof

First of all, make sure your camper roof is free of mud and dirt before trying to seal it off. Otherwise, there will be problems with adhesion. A pressure washer can take care of tough grime very quickly (just make sure not to damage your camper). 

However, if you don’t have access to one, any hose should work just fine. Be sure to clean off all of the dirt and debris before trying to seal your camper roof.

Step 2: Get Your Rubber Roof Clean

Once your camper is nice and clean, you’re going to need a liquid rubber cleaner for this next step. This liquid will remove any algae that has grown on top of your rubber roof over time, and it will prevent the sealant from bonding to it later on in this process. 

You should spray down your entire camper roof (or at least the part where you plan on applying the liquid rubber) with this cleaner until it’s nice and shiny. Just make sure no other areas are exposed at any point during the cleaning process.

Step 3: Cutting In

If there are seams or any other areas on your rubber roof that are not sealed, you’re going to have to cut in. Use a high-quality brush and follow the exact contours of your camper’s rubber roof. 

You can also use a paint roller for this step if it fits better with the shape of the roof (but always remember to clean it regularly). Try and make sure that there is an even amount of liquid all over your camper roof before you start applying the liquid rubber sealant.

Step 4: Applying Liquid Rubber Sealant

Finally, it’s time to apply liquid rubber sealant! First, pour out about one quart worth into a separate bucket (to make cleanup easier later). Starting at one end of your camper roof, begin to apply the liquid rubber sealant in a circular motion. It’s very important that you don’t stop and continue to go in circles until it is all applied (you should probably use a roller or paintbrush for this step).

Step 5: Letting the Liquid Rubber Sealant Dry

Finally, you need to let the liquid rubber dry before moving on to the next step! Find something else to do for roughly one hour. You’ll know that the liquid rubber has dried completely if there are no shiny patches left behind when you run your hand over it.

After letting the sealant dry, dump out any excess liquid rubber from the bucket onto your camper roof. Your camper should be protected after applying this method! Just make sure you don’t do any climbing on top of your camper until the next day.

Here are some simple tricks to seal a camper roof

  • Clean the roof thoroughly with a power washer
  • Apply a sealant such as Flexseal to all seams and cracks in the roof
  • If you have any leaks, use metal tape to make repairs
  • Let the sealant dry for 24 hours before using your camper again
  • Keep an eye out for any signs of leakage or damage after every camping trip 
  • Use a high-quality sealant that is specifically designed for campers and RVs at least once per year (or more often if you’re going on lots of trips)


As we head into the winter months, it’s time to start thinking about your next camping trip and what you need to do before this year’s adventure. One of those tasks is sealing up that camper roof so it doesn’t leak when spring rolls around. 

The process might be a little scary at first especially if you haven’t done anything like this yet–but don’t worry!

We’ve got all the information you’ll need to get started on getting your roof sealed for another season.
