Across all platforms, roof are probably my most talked about subject. Which makes sense because water damage is the number one destroyer of RVs, and the roof is usually where it’s getting in. I’m constantly reminding you guys to check your roof and stressing the importance of keeping up with your seals. Over the past year or so there was in influx of videos circulating “rv hacks” on your roof. These videos showed people using products like Eternabond or “roof tape” being used in place of lap sealant. Some going as far as saying to cover all of your seals on your entire roof with this stuff. These videos included bold claims that this tape was a “forever solution” to roof seals, and I’m here to tell you that simply isn’t true. While the name “Eternabond” may sound like it will last an eternity, that’s far from the truth. While this product is FANTASTIC at patching small boo-boo’s on the roof, it is not a long term solution and more importantly not a substitute for lap sealant on your RV roof. This “RV hack” is not only ineffective, it will actually end up costing you more in the long run. We’re all looking for ways to do things cheaper and easier, but I promise you this hack is neither of those as it will create more work and more repair costs when it inevitably fails. Keep your roof clean, and keep your seals in order, that is the absolute best “roof hack” anyone can do.

Can’t sell those seasonal resealing packages at exorbitant prices because eternabond just last so god damn long. I’ll keep my eternabond and regular maintenance that I can do myself now that I dont have to spend that time resealing with dicor.
Eternabond typically sells in 50ft rolls. If it’s intended for small emergency patches, I’d assume they’d sell 4ft strips for 20 bucks, not huge rolls. In your video, we have no way of knowing if the damaged tape is actually $120 eternabond or a $30 knockoff, which are common on amz. What I do is properly seal seals like the top of the roof Edge molding with non-sag lap sealant and then eternabond over it as an extra layer of protection
What you’re looking at on that pop-up are the results of a very poor install. Whoever installed that didn’t roll or tool the tape. If they didn’t do that there’s very little chance that they cleaned and primed the surface correctly. Anything installed poorly will end in a poor result.
I am gonna do you one better, if you put the right type of roof, we should not be having this conversation.
Why should I listen to a tech, may not be you; that didn’t put enough lap sealant the right way and tell you to use it? I used eternabond, the right one and it works and I then sand it and paint over it for an extra layer. I use lap sealant when I cannot use the eternabond. Key is to prepare the surface like you are going to use as a dinner plate.
Do it right from factory and use the right stuff and we shouldn’t have issues for long time. I know that we need to inspect regularly, but man the stuff I have seen in new RV’, most comes with issues already, but normally old people don’t go and inspect the roof.
Not listening to a tech,I replaced my entire roof membrane with a TPO roof and sealed all the the vents with the 6 inch Eternabond.and the front and rear cap the same way,its been 7 years now and every spring i wash my roof I check and its as good as the day I put on.i have never had a leak since so do as you will.lapsealent is a rv scam in my eyes.
