My roof is all fiberglass . But I need to redo long seams on each side and across both ends. I need to remove alot of old sealant . That was just straight silicone the last owner put on . I have some dicor for the very top parts but ends do I use that new tape style stuff ? And sides need to be a off white more firm style to stay in the seams. Any pointers would be great or recommendations where to find which one to use.

I'm a big fan of Eternabond tape (it's been around for decades) that I've used on both of my RVs. One with a rubber roof and my newest with the fiberglass roof. I use 4" Ebond on the end cap seams and 2" Ebond along the edges, full length.

After reading many postings by owners of various roof issues over the last 15 years, I went ahead and covered the seams with Ebond so I don't have to mess with it very often. Getting on up in years and sometimes get dizzy climbing up on the roof so that's a factor. Had it checked at the factory a couple months ago and it's still in good condition. No needed maintenance.

Here's my blog entry about what I do: Fiberglass Roof maintenance...

I think Dicor is great for very small repairs that will not shrink and crack over time. For large seams and panel to panel gaps, you can't beat Eternabond tape. It's impossible to tear unless you cut it with an knife and the glue is a tough to get off if you stick it in the wrong place. My other 3 coaches had Dicor and I was always having to check and repair the caulking. My current coach was switched to Eternabond and now I just have to check and have never had to make a repair after 7 years of ownership. You have to remove the old caulk to apply new caulk anywway, so you might as well install the tape and be done with it.

For Winnebago, follow these directions. Non-painted vs painted use different sealants. Painted is just silicone.

Winnebago Roof Seal


This is by far, the best answer for this question. I have given this same answer multiple times on different forums. And I'm not a fan of the "Scotch tape" aka Eternabond either. As has been stated on here more than once, Eternabond is not designed for strength, just it's ability to seal. Besides, after paying as much for this coach we have, I'm not wanting to destroy it's looks by putting tape all along the top edge.

We read of a few issues with a Winnebago/Itasca roof on here, every now and then. And what to use to remedy those issues is always kind of a debate. Winne has a callout list for what sealants/adhesives are to be used, where. But, the video what Mile High provides is pretty much what Winne/Itasca calls for, for certain model motorhomes.

Lichtsinn RV is right down the street from the Winne/Itasca (well, used to be Itasca) factory so, they coordinate lots of maintenance and repair procedures.

Eternabond all the way. I've seen it used very successfully on a church roof made of metal 2 stories up. Nobody can see it anyway. [emoticon]


4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.

Considering the coach is a 1992 Itasca Sunrise Eternabond tape is going work best.
