5 Common RV Repairs and How Long They Should Take a Professional

If you own an RV, then you know there are repairs that take place. The difficulty is we often wait until we see evidence of the need. If we were proactive in our approach, we would probably save ourselves a lot of headaches—and money!

A lot of the repairs are possible DIY jobs, but many people want to take it to a professional. If you are looking at a RV shop, you might be wondering if you are being treated fairly or being overcharged. At One Source RV, we are a trusted resource in the RV industry and want to make sure you are being treated fairly and with respect. So we decided to show the top 5 common repairs and how long they should take.

A Roof Reseal is one of the most common repairs

Typically, this repair comes a little too late. This is one of those things you want to maintain and not repair. Your RV roof should be inspected bi-annually—or after any severe weather—for possible leaks or abnormalities. 

Before performing any roof repair, you will want to determine what kind of roof you have. Typically, RV roofs are made of aluminum, fiberglass or rubber. There are many variations of rubber type roofs such as EPDM, vinyl, tpo and others that we may not list here. You can look this up in your RV manual.

Upon inspection if your roof looks really good and you don’t see any areas of possible issues, you can do a “seal over”. A seal over would involve several tubes of the correct sealant or a brush on sealant. You would seal over all the seams. This can typically be done several times before you need a complete reseal. This would take a couple of hours to do well. 

A Roof Reseal would involve removal of all sealants and resealing all seams with reseal material that is compatible with your roof material. This could take four to six hours for a professional and can cost $800-$1,000. It would probably be wise to ask your RV professional why they think it needs a Roof Reseal instead of a “seal over” to see what they say.

A roof recoat would be done to recoat the entire surface of the roof material with a newly applied sealant. This would typically be done when the actual roof material is starting to fail and discolor or start to show cracks and imperfections. This is sometimes an option other than roof replacement. This repair when done correctly could cost double the amount of a reseal or even more. This job compared to complete roof replacement to be discussed in a future article.


Black tank maintenance is important.

If you want to prevent clogging—and all of the fun that goes with that, then you need to maintain this tank. The typical issue of most black tank problems comes from RVers leaving their black tank open at a campsite. A black tank is designed to have the valve closed. This allows liquid to build up with the solids alongside a proper black tank treatment. If you don’t allow this to happen, your solids build up and become quite solid. This build up turns into a clogged tank and will set you back $250-500 dollars. 

Heating and Air Conditioning Fans Stop Working

These climate control units are wonderful things to keep our creature-comforts with us while enjoying nature. But these units need regular maintenance. Both the air conditioner and the furnace have fans inside of them that move the air through the coach. When not used frequently, these can seize up and cause quite the problem. 

Many RVs are stationary for long periods of time. This allows them to become homes for many animals and insects. One of the more frustrating insects for RVers is the Mud Dauber. I am sure this little insect is amazing in some ways, but it is a real pain for our HVAC systems. When given the chance, they will create a nest in your fan system that gets as hard as concrete. This will quickly seize up your fans and prevent you from enjoying that system. 

The fix for this is to access the fan and remove the nest. With the air conditioner, this isn’t as much of a problem. The furnace—depending on where its located—can be another story. This job could be a 1 hour job or a 4 hour job if the furnace needs to be removed

A good preventative measure is to install aftermarket bug screens on all the entries to your rv appliance. Just make sure you inspect these screens every so often to make sure they don’t get debris built up.

Many RVers only use their rig in the summertime and that can mean our furnaces don’t get used enough. It is important to turn on your furnace and let it run for a short period of time every month. The same is true of your ac unit, but that typically isn’t a problem for most RVers. 

Battery Maintenance

Far too often we forget that batteries need maintenance. I believe this is hard because our electrical system at home requires virtually no maintenance unless a breaker is tripped. But RV batteries—specifically “wet cell” batteries—require filling with distilled water. When a battery isn’t monitored, it will be damaged beyond repair. 

Batteries aren’t difficult to replace, but very expensive components in any RV. These units can easily run you a bill of thousands of dollars depending on what you replace them with. If you do have a battery that isn’t salvageable, I’d encourage you to recycle that battery and find an enclosed battery that doesn’t need distilled water.

The Road Ahead

It might seem like a lot to think about and consider, but there are a lot of miles to drive. If you look at the list, a lot of it can be cared for every 6 months or by replacing specific parts. If you have any questions, concerns, or upgrades you are considering, reach out to us at One Source RV, where the staff is backed by the experience of current or formerly Master Certified RV Technicians and other service professionals. And our desire is to be the one place you can go to for honest, accurate information that keeps you on the road for years.
