I used to follow the landscape fabric religion. But GF
convinced me
that plain old newspaper works as well. It's a lot
cheaper and less
bark mulch is needed. In fact newspaper (4 or 5 pages)
doesn't allow
any light through and weeds don't seem to come up through
it. Now I'm
thinking about how hard it will be to install it over the
existing fabric.

I would advise removing the existing fabric
before adding the newspaper.

My first rosebed came with the house and
already had landscape fabric in it. Weeds
grew through it and being new to roses, I
just pulled out the old fabric and put down
new, once a year while the roses were dormant.
What a chore! I don't do that anymore.

As far as I know removing the old fabric
didn't harm the roses (some died, but that
was probably for other reasons).
