Installing 3/4 t&g hardwood flooring over kraft paper directly over the
subfloor (no underlayment) has always been the norm in my neck of the woods.
The kraft paper is a water resistant membrane. I think it's the same stuff
that goes over insulation only it comes in rolls. I'm sure the 30# felt
would do the same but is prolly more expensive and overkill. IMHO of
course.

The Real reason it is there, whether it be kraft paper, red rosin paper, or
felt paper is to eliminate squeaks. It simply creates a barrier between
flooring and subfloor to eliminate wood rubbing against wood. Any one of
the products listed above serve the same purpose equally well. There is no
need for a moisture barrier, and none of these products are meant for that
purpose on a floor. The papers listed above are all close to each other in
price, and are similar in installation with felt paper being somewhat more
difficult simply because it is thicker, and the creosote gets on your hands.

The paper has a few reasons for being there but the two main reasons
benefit the installer. One is it's easier to see your lines when you're
marking the joist (all installers don't mark / nail the joist but
whenever possible it should be done). Two is that it makes it alot
easier to kick the pieces into place - the flooring moves easier on
paper than bare subfloor. As for it being a moisture barrier, it doesn't
hurt but there are much more effective moisture barriers.

Do you have a local building inspection department? What would they look
for? No one would be better informed regarding practices local to you.
You were the person installing the recycled maple, right? How's is going
with reducing the musty odor?

Oh, roofing tarpaper, eh? I thought you meant hat fabric.

Yeah, what he said. The main reason is to minimize/eliminate squeaking
between the 2 wood surfaces. Mark L.
