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 , and a tube of Dicor should be about 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.

Full-Time RVers since April 11, 2003, we share DIY (do it yourself) RV maintenance, repair, travel, upgrade and operational tips & tricks.
While we’re not RV technicians, we’re very mechanically inclined and have learned a lot about RV systems over the years. We’ve handled most of our own minor service, maintenance and upgrade work on both of our RVs.
We meet lots of newer RVers who are eager to learn some basics about using, maintaining and caring for their rigs. After more than a decade on the road, we’re happy to share what we’ve learned (some of it the hard way). 😉 We hope our experience can help other RVers go DIY, saving time & money while experiencing the satisfaction of a job well done.
We are not professional RV technicians and do not pretend to be experts on any particular topic. We mostly know about maintaining our own motorhome, so be sure to confirm that all methods and materials used are compatible with your equipment. Every RV is different, so your systems may not be the same as ours. Regardless of what we recommend, consult a professional if you’re unsure about working on your RV. We encourage you to do your own research. Any task you perform or product you purchase based on any information we provide is strictly at your own risk.
