Leaky RV Roof Repair – Quick and easy instructions

Fact checked by Joseph Varney

You probably find yourself distraught by a leaky RV roof a couple of times, right? In fact, this is what RV owners frequently complain about.

Most of the time, people end up selling their RVs with low chances of success. I mean, who would want to buy something that requires fixing? However, if they do sell, itll be for a very low price which isnt enough to pay for the years you spent taking care of your mobile secondary home.

I understand this makes you want to learn how to do repairs. So, I made this DIY guide to help you learn how to repair an RV roof leak. Check it out.

Dont Store Your Rv Outside

Finally, you can prevent the vast majority of RV roof leaks if you store your vehicle indoors during the off-season. The top culprits of leaks are rain, snow, and shifting temperatures. We already mentioned using an RV cover and a carport when you park for short durations, but these can only do so much.

Harsh storms can eventually work their way through covers, and carports are open on most sides. This exposes your RV to a variety of climate risks, and it would eventually develop a leak.

In order to avoid this, its best to store your RV indoors if you can. As mentioned above, some people have garages that can accommodate these vehicles. If this isnt plausible for you, look into climate-controlled storage options in your area. They might be a bit pricey, but youll save yourself the hassle of dealing with water damage.

Overall, its possible to prevent RV roof leaks as long as you take the right precautions and keep a close eye on your roof. Fix minor flaws as soon as they form, and be consistent with your maintenance routines.

Make sure you keep track of all your RV maintenance and repairs with an online tool such as RV LIFE Maintenance. Not only can you keep all of your documents in one place, but youll also receive timely reminders when maintenance is due to help you avoid costly repairs and potentially serious accidents.

    What Have We Decided About Flex Seal Rv Roof Repairs

    Many RVers have used Flex Seal for repairing leaks in their RVs. From reading RV forums, it is clear that some were very happy with the results while others had nothing good to say. Relying on Flex Seal as a permanent solution to a leaky RV roof may not be a good idea. It could be argued that Flex Seal is not designed for RV roof repairs. However, many of the negative reviews seem to stem from those expecting Flex Seal to be a permanent repair.

    The ready availability of Flex Seal at major retailers, as-seen-onTV stores, and online, makes it very easy to keep a few cans of Flex Seal Liquid, Spray, or Shot on hand for emergencies. It might not hurt to have a roll of the tape as well. Flex Seal is also relatively inexpensive. You can apply it on almost any surface, in cold weather, hot weather, on dry surfaces, and wet surfaces. It does stop leaks and will certainly get you to a point where you have the time to shop for a more permanent roof repair for your RV.

    Personally, I keep a roll of Eterna Bond Tape, Dicor Self Leveling Lap Sealant Caulk and another tube of Dicor Non Sag Lap Sealant Caulk on board my RV for any emergency repairs I have to make. Ive used flex seal and although I think it worked, it was really hard to work with. Have you used Flex Seal to make a repair on your RV Roof? Please share your comments about it below.

    RV Roof Replacement! No More Roof Leaks!

    There are two common types of RV roof leaks. The ones you see immediately and those that go unnoticed for weeks.

    The latter will usually present itself in the form of a dark or wet spot that appears on your RV ceiling. It could prove difficult to pinpoint the exact point of entrance for these leaks because they will usually be very small. There may not even be a visible hole if the leak is small enough.

    The best way to deal with these types of leaks is in broad strokes. If you are using tape or caulk to repair the leak, then be generous with distributing your chosen material. Even if you cant find the exact spot of the leak, you should be able to locate the general area and tape or caulk it accordingly.

    If you are attempting a repair in the middle of a storm, it may be necessary to do a temporary patch job until you find a permanent solution.

    How Do You Know If An Rv Has Water Damage

    RVs are regularly exposed to a variety of weather elements such as rain, ice, or snow. If you travel through moist conditions such as these in your camper or RV, you must check for any signs of long-term water damage. Not sure how to do that? Just check for any of these tell-tale signs:

    • Staining of soft spots such as overhead cabinets.
    • Discoloration of cloth, paper, and wood materials.
    • Growth of mold in corners and other areas within the RV.
    • Certain areas on the roof are somewhat spongy.
    • The bed area has traces of dampness and leaks.

    When you spot any of these, pinpoint the source and work on it as soon as possible. This will help you minimize the repair costs and prevent the problem from spreading further into other parts of your self-contained RV.

    How To Fix Rv Roof Problems

    Fixing an RV leaky roof is now going to be easier than ever before. Here are three steps to follow

    • Know the source of the leak
    • Apply temporary fix
    • Make a permanent fix

    Bear in mind that each type of leak is different and requires different materials to fix it.

    That said, what do you need to do in case you find out that your RV roof is leaking? A first step is a preventive action, of course. In this case, identify the leak to prevent the problem from getting worse.

    So, how to inspect the leak?

    One of the best ways of identifying leaks is to do a regular inspection. It can be done either from the interior or from the exterior of your RV.

    Prior inspection for roof leaks can help you prevent problems from becoming anonymous. It is recommended that you should inspect your RV after one year. However, if you are using your RV outside regularly, it is wise to inspect the roof at least twice a year.

    It is also a good idea to check your RV roof during weekends if you are going for a vacation.

    Interior Inspection

    It is the easiest place to start your inspection. Simply take a look at your RVs roof from the inside and identify possible damages. If you find any water stains, that means you have a roof leak somewhere.

    But not all roof leakages appear on the ceiling. So, you need to check on the walls because some leaks can run to the side of your RV.

    Exterior inspection

    Apply temporary fixes

    How Often Should I Check For Leaks

    It makes sense to check before you decide to use it, and during the off-season, it doesnt hurt to check every 4-6 months.

    In general, if youve sealed it right, you shouldnt have to replace it for another ten years, which will be a big weight off your shoulders. Be sure also to check other parts of the camper, like the caulking or trims along the RV, for cracks.

    Regularly Clean The Roof

    Another good way to prevent RV roof leaks is to regularly examine and clean your roof. Sometimes the problems start small, so its easy to miss them unless youre paying close attention. If you establish a consistent time to clean your RV and check it for leaks, you can save yourself a lot of trouble down the road.

    Begin by climbing onto the roof or using a ladder. You need to be able to physically see the top in order for this process to be helpful. From your vantage point, examine the roof. Pay extra close attention to the seams because this is often where water will seep through.

    Next, gently rinse off the roof to expose the base. You want to clean it thoroughly, but dont be too harsh because you could worsen any weak areas. Carefully apply soap and scrub any debris off the roof. Then you just need to rinse the soap off again and let the vehicle thoroughly dry.

    Re-check the surface once youre done cleaning, just in case you created any holes or scratches.

    How To Paint A Fabric Ceiling In Rv

    Its easy to paint fabric ceilings in RV, but there are a few things you need to know before you get started.

    First, make sure the surface is clean and dry before you begin. Next, choose the right type of paint for the job. Latex or acrylic paints are best for most surfaces, but if youre painting over fabric, youll want to use fabric-specific paint. These paints adhere well to the material and resist fading and staining.

    Once youve chosen the right paint, its time to start. Begin by painting the edges of the fabric ceiling with a brush or roller. Then, working in small sections, paint the rest of the roof with a roller. Make sure to paint in the same direction as the fabrics grain to avoid leaving brush strokes. Once the first coat of paint is dry, apply a second coat if necessary. Once the second coat is dry, youre done! Your newly painted fabric ceiling will add a touch of style to your RV.

    Types Of Rubber Roofs

    Rubber RV roofs have become increasingly popular.

    These types of roofs are relatively light-weight and they age very well. Theyre also easy to apply to existing roof structures so many people will apply them right over top of their existing leaky roof.

    There are three main types of rubber roofs that people like to use on their RVs.

    The first is usually just a quick fix that comes in the form of Flex Seal. This product can be sprayed on like spray paint and Ive read many mixed reviews on the product.

    This being said, there are more advanced liquid rubber roof products that you can buy to apply to your roof.

    Recoat The Roof Surface

    At some point during your RVs life, you will probably need to recoat the roof. This is a protective layer that covers the roofing material almost like paint.

    Over time, the coating becomes chalky and may wear off. Although this is normal, its a clear sign that its time to recoat the roof.

    The coating is important because it helps to increase the waterproof and weatherproof capability of the whole roof.

    Be sure to keep in mind that you might need a specific type of coating depending on the type of roof material you have.

    One method of recoating is an RV liquid roof, which is an EPDM coating that you paint onto the roof of your camper.

    The liquid roof costs almost $90 per gallon, which covers about 42 square feet. For our 30-foot by 8 ½ foot camper example, wed need about six gallons to cover the roof.

    You can save if you buy the material in larger quantities, such as four or five-gallon pails.

    Once dry, the liquid roof barrier protects it from UV rays from the sun and also adds weatherproofing to block moisture and slow wear-and-tear from the elements.

    Find The Source Of The Leak

    The first thing youll want to do is locate the source of the leak. Depending on the leaks location, your solution may be different. Most leaks are on the roof, so start there.

    To locate a leak on your RVs roof, grab a ladder. Some RVs are built to withstand your weight on top. These typically come with a ladder attached to the back or side to allow you to climb up. Some RVs, however, are not made to sustain much weight. If in doubt, refer to your manual. If your RVs roof is too weak, grab a safety ladder and climb up next to your RV.

    Once you have a clear visual of the roof, inspect it for noticeable cracks or holes. If youre having a hard time, pay close attention to the areas around HVAC units or other roof-mounted accessories. The seals around these mounts tend to dry out and crack causing leaks into the RVs interior.

    Another way to isolate your leak is to go inside the RV and look for any water damage or dark spots. Some leaks start inside the walls and drip down. So pay attention to the ceiling, walls, and floors.

    Note: be proactive and inspect your RV for noticeable leaks or cracks at least twice a year. Once at the start of the season, and again when the season is over. This routine inspection can help you identify problems before they become unmanageable.
