I have about R-19 insulation in attic. I want to add R-30 more. R-30
batts in HomeDepot have paper vaopr barrier. Should I remove it before
adding R-30 batts over existing batss to prevent double barrier or I
can put them as is?
Are you sure that blown-in insulation won't be easier to use. And check
out rebate programs offered by your utility co., county, etc. that will
reduce your cost -- and maybe even free, depending on your income.

It's interesting lately how many responses posters can receive
and sometimes not even one of them will address the question that
was asked; at least one asnwered you so far. Sometimes everyone
only wants to give a different solution rather than answer the
questions. Oh well, that said:
If you use the paper-backed, you should use a utility knife or
something similar to slice it open here and there. You don't
have to shred it; just a few foot to three foot long slashes here
and there will be enough.
It might be cheaper, as others mentioned though, to buy
unfaced insulation - worth checking on unless it's not on sale
like the faced stuff you're looking at now or you need the facing
for some other reason like dust containment.
I'll let you be the judge on the other suggestions - blown, etc..
Keep pets & kids away while you're working with it; tough on the
lungs eyes and skin.
Check your local utility company for programs. With rebates, it could be
cheaper to higher one of their certified installers to blow in fiberglass.
In Mass., there's a 50 percent rebate up to $3,000 through NSTAR.
