mine has been on the roof seams for 5yrs
no problems so far, knock on my wooden head
Did you have leaks on the seams when you applied the tape, or used it only as precaution?
Main problem with the tape is that dual layer is hiding imperfections and wrinkles holding the water.
You are not aware about the problem till the water shows inside, or roof collapse.
5 months ago I applied latest technology roofing coating on my house flat roof. I had dealt with black and silver coating in the past and results were mixed.
I keep eye on new stuff and it looks really good. The roof had small leaks last rain season, so I am waiting for next real test this winter, but I think I know what I will use on my camper rubber roof this winter.
Main advantage beside lifetime warranty - with nice white coating you will see each hole or crack.
