I have a persistent leak in rubber roof in one corner of 17 year old FW. Had anyone used Flex Tape on a rubber roof? Is there any reason not to? My plan is to cover an area of 8x4 feet - lot cheaper than a whole new roof.

Not Flex tape but I have successfully used white Eternal Bond tape to cover minor tears on my rubber roof and had no leaks and the tape lasted for many years until I sold the trailer. Also used the same tape to cover a foot long narrow gash from road debris on the very low front left side of trailer just above floor frame. Again the tape prevented water from entering the TT and tape blended in well with white side of TT. I love Eternal Bond. Easy to use and work with and sturdy long lasting.

No home grade tape is intended for long term use, especially if exposed to the elements. Eternabond is designed for roofs and has a long record on RVs.

I, too, have used Eternabond in the past with very good results. I, personally, would rather use the Eternabond on a rubber roof. I have never had much luck with any of the Flex Seal products.

I agree - use Eternabond.I too have not had any luck with the flex products. At all. Especially for a longer lasting solution.Eterna in Eternabond is short for eternity. This stuff won't come off.Mike

You can get Eternal Bond in wide strips to cover your area then apply Dicor liquid rubber roof over that. That is what I did and again no leaks but of course my tears were small and short and my TT was flat roof.
