Actually, it is not. It is very good for sealing up leaks, it has no mechanical strength.
I had the same thoughts when I did mine. It came apart after 7 years. The tape will slow the degradation of the sealant from UV exposure, not stop it. The problem is that with the tape, you can't inspect the sealant.
I was in a very windy spot with big gusts when it came undone. Luckily, the whole thing didn't come undone but it lifted about 10 feet of the roof.
I called Eternabond after this and was told very clearly the it had no mechanical strength.
I still use Eternabond just not for this application. It is a fine product to keep water out, not hold down the roof.
