When Your RV Leaks, Repair It with One of these Methods

Your RV is your home on the road. When you’re in it, you expect many of the amenities and comforts you do from your own house. So when something goes wrong, you want to fix it and fix it right. For example, with RV leaks, a repair either gets done the right way or you end up on a vacation you can’t wait to finish. So if your RV leaks, the repair options below are going to be your best bets.


Caulk is an old standby for any kind of crack or leak in your home. The same goes for RV leaks. To repair your RV with normal caulk, however, is not only a waste of time, it will turn into a much bigger problem. Silicone sealer is especially harmful because it will eventually shrink, pulling away from the crack. When this happens, water is allowed back in and can get trapped.

If you have just one hole or crack that you can manage with caulk, be sure to visit an RV store where they can recommend you the correct type. If it’s not made specifically for RVs, it will make matters worse.

Liquid Coating

Liquid coating is a great option for fixing RV leaks. The repair you made with caulk can be amplified by putting liquid coating over it. This method involves petroleum-based rubbers that will form an impenetrable barrier above the roof. Whether it’s just one area or the entire roof, liquid coatings will keep the elements from sneaking in. They’re also a great proactive way of sealing your RV’s roof before any leaks happen in the first place.

EPDM Roofing

Another option, similar to liquid coating, is called EPDM Roofing. Ethylene propylene diene (the “M” is a reference to the class of rubber) is as effective as the liquid rubber coating, but with a different application process. EPDM rubber is produced in sheets that can be as wide as fifty feet with a length up to two-hundred. Obviously, this won’t be necessary for your RV. Using an RV-safe adhesive, you can glue EPDM roofing to the top of your vehicle for a secure, impenetrable veneer. This is an especially effective method if you don’t know where the leak is originating from (as often the leak will pour into the RV from one area, but originate elsewhere on the roof). Its only drawback is it can be tough to negotiate areas where your RV’s roof has protrusions, like your skylight or an air conditioning unit.

Other Sources of Leaks

Sometimes the roof is not the issue when your RV leaks. A repair professional may need to be called if water is leaking in where the windows meet the walls or around your RV’s accessories. Any leaks that occur near electricity need to be immediately addressed by a professional repairman.

If your RV leaks, don’t let the problem go on too long. Use appropriate caulk, liquid roof coating or an EPDM roofing material as soon as possible. Don’t attempt the job if you know it’s out of your scope, though, as this could result in a much more costly outcome. Definitely get a professional involved if a leak is close to a source of electricity.
