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.

@mikemotorbike4283 Жыл бұрын

@@nenanenica6783 yes, good observation. Its an overlooked water entry risk. The entry point in this video would not be a problem, ironically, because his sealant seems to cover the tube to the roof completely. Even without the base and cap, rain would just drip into the tank, presumably. But water is famous for sneaking around. So, the double seal.*edit* I just read a comment below which said the wider hole around the base of the vent pipe should NOT be sealed to the roof... in order to let moisture out of the roof space from the open gap around the base of the pipe.

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.

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.

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 ;)

Dicor will not fill large spaces, especially horizontal ones, as it will just sag down and fall through the space.

My vent pipe had about 3/16" space all around it. I said "sheesh- what a cheesy job!" I spent about 2 extra hours fashioning an aluminium "washer" with very little clearance(1/32" or less) that had an "apron" of about 1-1/2" all around and caulked the edge to the vent pipe and fastened it down with a good caulk (Chemlink M1). Then I talked to a guy that was a dealer repair guy (with 30 years experience) and told him what I had done and he said "That was a mistake. You just closed up the roof vent that allows moisture to escape from the "attic" instead of being in there to create dry rot and mold" So I spent ANOTHER 1+ hours UNDOING my "really good job" sigh.....

Hi Bart! We are not 100% certain, because we don’t have those caps anymore, but we’re pretty sure this is it: amzn.to/3hK0ND0 But the reason we don’t have those caps anymore is because we’ve replaced them with a far superior design, the 360 Siphon vents. If you’re going to replace any of it, you might want to spring for a little more and upgrade to these fantastic caps, that do more than just cover the pipe. They actively draw air up out of the holding tanks, reducing or eliminating tank odors entirely: amzn.to/3yrNrCg That link is for the newer design, but even our original style 360s are fantastic! Here’s the video we made about it: kzfaq.info/get/bejne/ad6IaZOUqK7bnIE.html Hope this all helps.

Hi Kathy. So sorry to hear you’re having trouble with this. Unfortunately, if the plumbing vent pipe is cracked, any water that gets down into the area around it will likely end up in your roof, or inside your RV. Either way, that water can cause extensive damage over time. You’ll want to have that area properly sealed to prevent leakage.

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.

Hi Elizabeth! Thank you so much for the kind words. It's always nice to hear that people find our videos helpful... it truly makes our day!! As for the screw... it's probably not absolutely necessary, but we'd still recommend using it. The clips that hold the cap in place seem to be fairly strong... but adding the screw is just an extra safety measure to keep them from being torn/blown off.

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.

@RVgeeks 8 жыл бұрын

+Nick J Hi Nick. Our first motorhome had a rubber roof, and came from the factory (we bought it new) with Dicor around the vent caps, antennas, solar panel, ladder and every other seam on the roof. And so does every other RV with a rubber roof we've ever seen or worked on. Dicor is actually the standard roof patch material used by professional techs industry-wide, and is specifically designed for EPDM & TPO roofs (commonly called "rubber" roofs). If you had separation on your roof where it was applied, there must certainly have been some other underlying problem with the glue, as Dicor would not cause any issue on an otherwise-healthy rubber roof. Sorry you had a problem (sounds like a real pain), but it wasn't the Dicor that caused it. Is it possible that some other chemical was used in conjunction with the Dicor, or that this was some kind of unusual roof material?

@nickj8926 8 жыл бұрын

+RVgeeks Thanks for the response. Easy to understand that Dicor is the industry standard and easy to see that Dicor is already to used to seal all of my other vents and skylights without any bubbles. Let me explain in more detail and I think you will see this in a different light. After removing the existing Dicor and black tank plumbing vent, I observed that the roofing material was fully intact with no air bubbles. The only exception was right around the opening of black pipe, about a 1/2 inch around the opening where it appeared never to have been glued, a very small area. To be clear: there were no bubbles whatsoever and the roof was completely intact except directly around the pipe opening. I then installed the new vent (360 Siphon, at your recommendation - they look great!) and applied the Dicor over the screws and around the perimeter of the vent. I then applied Dicor as shown in the video, about 3/8" thick and about 1 1/2 inches wide. Looked just like your video when finished - the Dicor material is awesome and easy to handle. Everything looked fine. Here's the rub: I climbed back up after about and hour and could see that air bubbles had pushed up around the entire perimeter of the sealant, outside of the sealant. To the touch, I could also feel that there were air pockets underneath all of the area that the Dicor was applied; keep in mind there were no bubbles there before. I didn't panic but added another 1 inch of Dicor around the perimeter to cover up the air bubbles that had pushed up outside of the previously applied Dicor. After another hour I climbed back up to see that new air bubbles had pushed up outside of the second application of Dicor. So these bubbles are now about 4 inches away from the pipe opening and occurring in areas that were not compromised before I applied the Dicor. Its hard to argue the bubbles weren't caused by the application of the Dicor because the more I add, the more the bubbles that were never there before keep traveling. If I were to add more Dicor, the bubbles would just travel further out. An anomaly? No. The exact same thing happened on the gray tank plumbing vent. Now I'm left to figure out how to stop the bubbles from growing even larger (suggestions are welcome). I also need to replace my skylight, so it will be interesting to see if bubbles form and grow, given that SB140 is the sealant for that job. Your videos are right on the money, very instructional, and easy to watch. Wanted to make sure this isn't critical of you guys, just that Dicor clearly caused an issue for me. May be strange and weird but it happened.

+RVgeeks Update. One week has passed. The air bubbles have disappeared! This is confusing. No changes in the weather, heat, or humidity since my last post, so not sure what has transpired. I've read all the theories about air bubbles coming and going over time but I don't believe this is a run-of-the-mill occurrence. The air bubbles have not only disappeared but the rubber roof around the vents is as snug and attached as it was before installing the new vents. Is is possible the small amount of distillates contained in the Dicor temporarily moistened the roofing glue and softened and detached the roofing material, and as the Dicor cured, the roofing material shrunk back to original state and glue dried and reattached itself? This is confounding but I'm relieved. I was always a believer in Dicor but could see there was a direct cause and effect in this instance. So, to all who have read through all of this: now please ignore it, unless the same thing happens to you. And if it does, don't panic - give the Dicor time to cure. Sorry for the confusion!!!
