I’m about to re-roof a house. The current roof is about 25 years old. This may be a stupid question: Should I leave the old tar-paper on and put new felt over it, or should I strip the old off? Some of it is in OK shape.
Thanks for your input…

I can't remember a time I left old felt on a house. A couple reasons off hand: if some of it is torn up, there could be junk under it; it is undoubtedly punctured and torn; (um, what else?) I'm obsessive and like things to look neat and new, even if I'm gonna soon cover it up.
It is normally too torn up in the shingle removal process to be much good but we have left it occasionally. It doesn't do any harm and the benefit of leaving it in place is an additional slip sheet and cushion over old sheathing.
If there is any poossibility of rotted wood decking, you have to remove it to inspect and repair
Excellence is its own reward!
Thanks for the info.
I was concerned that the extra material might telegraph through the shingles after time, but it probably won't if I roll it out differently than what's there. I definately agree with inspecting the decking, as I've already noticed problems that will need repair.
I understand it's starting to get cold... da. I recently moved from Kennebunk after 15 years, and 35 yr in N.E... to CA. I miss N.E. already, but can't say I'll miss the winters... I need sunlight as I'm getting older I guess. Anyway, thanks for your replay.

Rip off the old loose stuff, for the reasons previously posted. Don't obsess over any stuck pieces, though.
