,EVERY RVer should have a tube of Dicor self-leveling lap sealant in their toolbox! You can find it here: http://tinyurl.com/dicor-sealant
Just about everything attached to the roof of an RV is a potential entry point for water. The TV antenna, vent fans, satellite dish, plumbing vents, solar panel mounts or anything else screwed into, or transitioning through the roof to the interior are places that invite leaks.
The main line of defense against water damage is vigilance — periodic inspection of the Dicor waterproof sealant. Dicor self-leveling lap sealant is ubiquitous in the RV industry, sealing roofs on everything from pop-up trailers to diesel pusher motorhomes and everything in between.
The best way to avoid ever developing a leak in your RV is to check the roof at least a couple of times a year, looking for any cracks in the Dicor. One of the surest signs that an owner is meticulous in caring for their RV is to look for the tell-tale signs of Dicor patching on the roof. Dicor develops small cracks over time, and the periodic application of fresh Dicor to cover those cracks leads to the patchwork look of a well-maintained roof.
Dicor is available at just about any camping supply store or RV dealer, and requires only a standard caulk gun to apply. Before applying new sealant, just clean the area to be patched with mineral spirits. We have a fiberglass roof but if you have a rubber (EPDM) roof, it’s OK to clean the Dicor with mineral spirits. Just go easy on the quantity, being sure not to soak the rubber.

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.
