Landscaping cloth works better - get the pro grade, say at home depot. I
believe it is made of glass fiber felt, which lasts a very long time, yet
allows necessary drainage, which tarpaper does not, and will make the pavers
mossy, sooner. BTW I've seen bug/rodent holes on tarpaper that lays on the

If the pavers were laid down correctly, there is crushed stone, sand, or
other inorganic material, underneath for at least a few inches, and
possibly up to a foot or more, if done professionally.
Grass and weeds will not grow in this inorganic material, and the pavers
provide protection from light and air borne organic material, both of
which are required for plant growth.
Where the weeds start to grow, is in the sand between the pavers, and
they start to grow from the top. That is because, over time, organic
material, which will support growth, gets into the sand, and wind or
water borne seeds start to grow in this organic material. It seems that
a microscopic piece of organic material is enough to support the
germination of a seed (except where you want seeds to grow, like your
lawn, unless you apply lots of extra organic material and tend to it
If you pull out the newly started weeds or grass between the stones, you
will see that the roots are only an inch or so deep. They did not start
growing from beneath the pavers, so the addition of any roofing
material, plastic, or anything else under the pavers will not prevent
wind borne seeds from growing between the pavers.
