not necessary if they're in decent shape and you don't have a heavy multiple layer of old shingles underneath them. I left my old roofing intact when I put concrete tiles on about 15 years ago thinking the old roofing would just give me another line of defense against leaks and time has proved me right. no leaks- no problems!

Why should you remove the old tar paper when you put on a new roof?
yes, i am not trying to sound like a smart alek but if you don't know the answer please seek advice from a professional roofer you will be better off in the long run. ================== Check with the info on your shingles, some recommend NOT putting down tar paper first others go as far as voiding the warranty if you do install them over tar paper.
