Hi,

I have a 08 Itasca Latitude. I was going to bring the coach to a dealer to have the roof seams inspected and just recalled I have a 50foot by 4inch roll of Eternabond in the coach.

Should I just stick this over the existing seams?

Thanks,

Just covering everything with EternaBond tape isn't a good long-term solution. EB tape works great on flat joints, but around vent openings and other 90º seams it can allow water underneath, especially if the tape pulls away from the bend.

You might offer the tape to whomever you have do the roof inspection if they need it, but I wouldn't roll out 50' of tape and cover all seams or joints.

Thanks Bob,

Great advice as always.

If your roll isn't too old it would be OK, follow the Eternabond instructions exactly, including using their primer/cleaner;RV instructions are the bottom half of the page, EternaBond Video Library

Hi Ray,

I have it about 10 months.

I will do an inpection and take some photos.

The fiber backed EBond will work on corners but it is a PIA. We had a 2000 Itasca horizon I sealed the roof edges on. Cleaned the edges with Windex and dried them thoroughly. Split the 4 inch tape into 2 inch and applied with a wallpaper roller. Then painted with the sealer they supply. Worked great and unless you were looking, you would not see it.

When taping, it's very important NOT to stretch the tape ANY. I followed the video library instructions exactly, best I could anyway, I only wanted to do it once-and correctly.

If U R OK on the roof and can work safely, clean/ prep the roof w/ proper cleaner (NO petroleum/ NO Citrus), it is DIY and helps U sleep knowing what is up there vs guessing; (Might) even consider DICOR self-leveling the edges of the Eternabond :-) ?? At minimum, inspect before giving to dealer and maybe video suspect spots? and have them video/ pics of repairs to your phone?

I used some Eternabond on my last trailer and I wouldn't be afraid to do it. As mentioned, proper prep and installation is important. And, using some Dicor self leveling sealant around the edges of the tape adds another layer of protection. After that, inspect regularly and take care of any problems, but the Eternabond will reduce the amount of maintenance work you need. But....simply my opinion!

and a FRESH roll of Eternabond to the EMERGENCY SUPPLIES, replaced annually, is never a bad idea :-)

Got up on the roof today and took these photos of the seams.

This removes that mold on the roof and joints, while thoroughly cleaning away the black dirt (pollution)that's settled there. That will enable you to make a clearer assessment of your pending job.

Follow the Eternabond instructions exactly, no home-brew stuff some use. It may make the job more expensive, but you really do get what you pay for.
I wore-out a wood pastry roller doing the 5er roof; couldn't find a metal one like Eternabond recommends.
