Resealing

Just before it starts leaking. :)

Don't scrape it off. Wash the roof good, let it dry then inspect all the calked seams and repair the places that are cracked or even look like they may leak. Scrape the bad cracks then use dicor. Once a year.


Hope this helps

Use Eternabond when possible. It will last a long time without leaking.

Never! ... if it's not leaking or shows signs of leaking. As stated above, when you wash the roof, inspect the seams. If you detect cracks, reseal. Personally, I don't remove the old old. I just apply more on top of the old. But in RV ownership for almost 20 years or so, I've never recaulked more than a few inches combining all 3 TT's and pop-up combined, and I've never had leaks. If it don't need fixing, don't mess with it.

Here is a good description with pictures that should help you understand what to do better.

I've done nothing to my '97 30' trailers rubber roof but add a bit of self leveling Dicor in several places that the sealant had a hairline crack or had come loose.

The first time was in '05. Since then every 2-3 years I find another small area that need help.

If you don't know how its done let the experts handle that type of work.

I never heard of scraping it all off but a RV tech that does business with me said that's the correct way. I have always just inspected and sealed as needed
