UPDATE: Since making this video, we replaced these caps with 360 Siphon RV roof vents, which are AWESOME! Check out the updated video here:

We demonstrate how to replace a plumbing vent cap on the roof of an RV. Sun and age can lead to cracked plumbing vent covers on the roof of an RV, travel trailer or fifth wheel. Installing a new vent is a quick easy job, completed with just a few simple tools.

Older style roof vents may not match replacement vents, which makes it impossible to simply snap a new cap onto an older vent base. This means having to replace the base, even if it’s in good condition. A little Dicor (readily available from Camping World or RV parts & service facility) will seal the new vent. ensuring that your camper stays dry.

This is a quick, easy repair, completed without special skills in under half an hour. A new roof vent cover currently costs about $3, and a tube of Dicor should be about $10 at your local camping store.

This was done on the fiberglass roof of a Newmar Mountain Aire diesel pusher, but is handled the same way on an EPDM rubber roof. Be sure to confirm that all methods and materials used are compatible with your particular RV.

    Great instruction, good tips. I just replaced two cracked bases and covers on my 2006 Class A. Mine weren't self-tapping screws. I lucked out though, and the holes in the new base matched existing holes in the roof. Loaded it up with Dicor and I'm good to go. Thanks!

    Whenever I need to do any RV maintenance I search for something similar y'all have done. Let me say again that watching your videos has been empowering in that you make it all manageable/doable. So, I wrecked some roof vents and found this 8 year old video. Thank you! I have just one question: once everything is installed and you line up the hole in the top with the part inside that corresponds to the hole, you put a screw in the hole. Is the only purpose of that screw to hold the top cap on? That top cap says "PULL TO REMOVE". I was wondering if it is still a good idea to use the screw or not?
    Just a few comments: If I was smart I would have ordered 360 vents for the three broken ones. The 360 vent was the only one NOT broken. Unfortunately, it is too late to return these so…next time. Hopefully, I will not require a reminder again.

    Dicor looks so ugly. I put in on my van about a week ago and it's still soft.. looks like old bubble gum. I kinda wish I went with Permabond tape.

    We had to come watch this video after we heard you talking about it on Drivin' and Vibin'. Very informative and the wonky camera work did not bother us at all πŸ™‚

    Thank You very informative. My dog brought me a pluming roof vent with cap and all. The pluming roof vent was brittle and dry and dry rotten glad I got it before the rain. Good Doggie Otis. Replace all 4 vents after checking them out.

    Careful with that last screw to hold the cap on! If you camp in treed areas like I do, I would recommend you leave that screw out (They snap on really tight anyways). If the cap gets snagged by a branch, it'll just pop off. But if the screw is there, it might rip the whole thing out of the roof! I used the putty tape that came with my vents, then trimmed off any putty that came out the edges, and then use the lap sealant all the way around and over the screws. I wouldn't put the lap sealant underneath because you screw it down right away, and then the sealant spreads out underneath. And then with the screw covered, you can't retighten it. I'm sure it's fine, but I prefer my method πŸ˜‰

    Hello
    I've purchased a used pull behind camper and it's February so it's not warm in Kentucky. Can I use a heat gun to warm up the sealer around the vent pipes to make the job easier?
    I have a rubber roof and realize I need not to heat the roof up.
    Please help
    Thank you

    New RV Geek followers ….Sorry for the rerun comment I put elsewhere…. you are here because you save money and do quality work!! DO NOT buy that 99 cent tube putty at Home Depot!! It will say "30 year apply anywhere" etc…..the cheap stuff cannot take the motion vibration as well as cold-hot weather. Cheap stuff is good for the eaves under a house or inside the daughters closet before you paint. You gotta buck up and pay 10X as much (ouch) up to 10 dollars per tube for the quality stuff. I know this is an older Geek classic but remember when using any paint thinners, mineral spirits, acetone or M.E K, use a throw away rag, and let it dry outside before disposing of it. NEVER save paint rags in the coach. Spontaneous combustion in tight spaces will ruin your day!!!!!

    I am new to the RV world and when I went to the RV shop they sold me self-leveling tape along with the vent, so my question is does that work as well or better then the Dicor? Your video demonstration was wonderful and looks like I can totally handle this project, but I am wondering about using the self leveling tape, which you did not use. Great video for the do-it-yourself people. Thanks!

    Caution – this video offers great counsel but if you have a rubber roof, don't do it!!! The video mentions mineral spirits compromising the glue underneath the rubber roof but I'm here to tell you the Dicor product itself compromises the glue and creates bubbles wherever it is applied. Total disaster. If you have a fiberglass roof, good to go – you couldn't find better instructions. Rubber roof? Pay someone to do it or you'll regret it.

    Solar panels are a great place to lay tools and stuff on. Also, you do have a choice, buy a vent cap with the metal clips so they hold the cap on from the inside of the vent pipe.
    I used to use DiCore but got tired of redoing it every year so I now use sealant tape made for rubber roofs.

    To Tab, before you buy an RV head out to RV shows and shop around. And talk to people who own RVs before buying. You can also rent an RV to see if you can handle the lifestyle. Another thing about RVing, you'll make a lot of friends – it's a community thing. AND a lot of RVers are mechanically inclined. It helps when you have friends that know how to use a hammer and screwdriver! ; )

    Thanks for the video guys. Replaced vent caps this morning. Took about an hour and would have had it done sooner but had to make a few trips up and down the ladder. I was expecting screws but cap was attached with nuts. I also didn't want to drill new holes in my roof so I used my putty knife to make a couple of marks to line up all of the screw holes for the new cap.

    We're not exactly in the same boat, being that we both know which end of the screwdriver is for nail pounding (we pride ourselves on being stereotype breakers). πŸ˜‰ There are lots of ways to get RV service… RV dealers, mobile RV service technicians, Coach Care facilities (for us diesel pusher types), and even Camping World. There are lots of people who don't do any of their own RV service, so there's plenty of infrastructure in place to meet your needs. Don't let it intimidate you!

    Dicor will not fill large spaces, especially horizontal ones, as it will just sag down and fall through the space. I don't know if Dicor makes another product for this job, or if it even matters if the space is open. Maybe there's an RV technician out there who could could comment on this one? Or try going to the irv2(dot)com forums, where you'll find a ton of expertise on every RV topic. Hope this helps.

    Thanks for the great video. Just discovered my caps are cracked, but so is one of the bases. But when I pulled the cap off to replace, noticed there is NO SEALANT around the vent pipe. Just air between the vent pipe, roof, and base. What should I use to seal it up? I'm sure DICOR has a product I can use. Suggestions?
