How to Seal a Leaking Camper Roof

Are you a traveling freak who loves camping? If so, you probably spend a lot of your time on-road driving your camper. 

While traveling in your camper is great, it can become a nuisance if your vehicle roof starts to leak, especially when you’re carrying a lot of stuff in the storage area. Like every other vehicle, campers require timely maintenance and repairs, which, if ignored, can cause you trouble. 

In addition, a leaking roof can damage other appliances present in your RV. Therefore, one good idea is to solve the issue in time and avoid further problems. 

If you have a leaky camper roof and are willing to fix it, this post is right for you. Learn about how you can seal your water leaking RV roof and protect your belongings without much hassle.

How Can You Fix Your Camper Roof?

Sealing your camper roof is not that challenging. However, it is not as simple either. You need to complete the comprehensive process to ensure your roof does not leak any sooner again. 

In addition, you must have your necessary materials and tools ready to fix your camper roof. For instance, you need some objects to climb your camper rooftop since most work will be done on top of the RV. 

Since safety is a vital element of finishing the job correctly, you need to support your weight with several scaffold sets, plywood stacks, or anything similar to avoid danger. 

If you are not sure how to fix your camper roof the right way, don’t worry. Here’s a detailed guide to how you can seal your leaking RV roof in no time. 

Check the Camper Roof for Damage and Leaks

When dealing with leaks or repairs, you need to inspect the fault carefully. In addition, you must maintain a routine to check your Rv rooftop for potential damage and leaks. 

So, look out for areas on the roof that look damaged with cracks, worn-out spots, or thinning. Moreover, you must check the caulk or sealant condition on your camper roof and near the vent, skylight, doors, moldings, and roof seams. 

Clean Your RV Roof

The next step requires you to clean your camper roof. Therefore, you must climb up and search for any grown mold and debris collection. Be sure to scrape off any mold and junk you may find. Then, wash the rooftop thoroughly with soapy water to remove any dust particles. 

However, you must stay careful while doing these steps, as a moment of ignorance can result in days of regret. This is because you can easily tear your camper’s roof by applying too much pressure or force while cleaning. 

Now, you must wipe the roof with a brush or towel to remove the water left after washing and let the roof dry for a bit. Ensure all water has dried since it can dilute the sealant and lower its effectiveness. 

Repair Your Leaky Camper Roof

Once you find the camper rood all clean and dry, you can apply the sealant and finish repairing the roof. However, different RV models have various types of roofs. So, you apply the sealant suitable for your roof type. 

  • Rubber Roof 

Although rubber roofs are long-lasting and do not suffer from damage more often than other roof types, they still need regular fixes and repairs. 

You can use the Dyco Seam Seal or Leak Stopper as a sealant to repair your rubber roof. Moreover, Dicor EPDM products are good for coating as well. 

However, you must remember to wear protective gear while performing the maintenance since these chemicals are toxic to the skin and may cause health issues if inhaled. 

To spread the sealants evenly across the surface and roof seams, you can use a trowel or a brush. In addition, you should not focus on the affected areas only. Instead, you must try to cover the area surrounding the damaged spots for the best results.

Moreover, if you deal with severe damage, you can fill your rubber roof’s holes with tar for roof patching and then cover the spots with fiberglass tape. You can also apply additional sealant and tar layers over the tape to make it long-lasting. 

  • Fiberglass Roof

The sealing method for a leaking fiberglass roof is pretty much similar to the rubber roof. 

Although repairing a fiberglass roof is simple, restoring your roof’s original gloss and shine can be tricky. To get the finish back, you may clean your roof with Acetone or Butanone. 

This will help you remove any grease or stains. Once you are done, you may apply a gel coat wax layer in circular motions. 

But make sure you check the manual with instructions before doing so. You can repeat these steps until you achieve a splendid glassy and smooth roof. After the sealing process is complete, you may remove the extra wax.

  • Metal Roof

Before the fiberglass and rubber roofs boom, metals were the only material used for camper roofs. 

These roofs are long-lasting but may suffer from leaks on rare occasions. You can fix the leaking metal roof by applying Kool Seal. However, a regular house roof coating may also work. 

In addition, if you find any serious damage to the roof, such as structural damage, you can use an Eternabond tape roll to cover the holes. 

But be careful while using it, as once it sticks to any surface, it won’t come off easily. Moreover, you can cover your roof seams with this tape and then reapply a coat of the sealant to fix the leak for good. 

Temporary Fixes

Often, you may not have the money or time to perform a permanent fix for your camper’s leaky roof. In such situations, a temporary fix may do the job for you. Here are some quick temporary fixes you can count on:

Rubber Patch

If you need to fix a leak quickly in the middle of your trip, you can rely on rubber patches. The process for this temporary fix is simple, just read the instructions and do as required. 


Another quick and easy fix is to put a tarp on your leaking roof. You can tarp your roof by attaching the tarp with ropes or bungee cords. This will help your tarp stay fixed for a long time. 

In addition, you must ensure that the tarp is held tightly, or else the wind might blow it away. 

For safety measures, you must avoid using your camper HVAC system or other kitchen appliances as the blocked vents can increase the carbon dioxide levels in your RV. This means that your camper can easily catch fire, or perhaps your leaking roof may get worse. 

Tar Paper

In rare cases, you can glue tar paper on your roof. The paper is inexpensive and will suffice for a leaky roof as a temporary fix. You can apply tar paper easily by following the steps mentioned on the packaging or manual that comes with it.

Final Thoughts

Your camping trip can easily be affected by a leaking roof. Therefore, you must run a regular check to ensure your camper roof is not having any leaks. It’s better to always carry the necessary materials for a temporary fix to halt the roof damage and prevent further trouble.
