new felt or old felt???

My house just about needs new roof. I have couple of estimates. Some said they will install new 15# felt. Some said they will replace/repair felt only it is necessary. Who is correct and What should I do

New felt always. 15# is about .05/sq ft...installed for less than a dime. It's worth it.

Depends

Felt does not degrade as shingles do.

If you can strip shingles and still leave felt intact (which hardly ever happens), you can reapply new shingles with no problem.

The best approach is to strip the roof down to the sheathing then apply new paper and shingles as has already been mentioned.

Agreed.
Either way can be done.....but stripping the roof off and putting new felt is the "best" way to go.

What about all of the old nail holes left in the felt after tearing off shingles. In 30 years of roofing, I have never heard of anyone even considering re-using old felt.

cost difference

Thank you all for the advise. There is about $2,000 difference in the estimates. The felt paper costs not much. I guess most of the price is the labor cost.

Why so much? That's crazy! Is there something I don't know? How steep and high is the roof? How big? Dormers/valleys? If average 25 square home under 7:12 slope....then new dryin w/15# ASTM felt should be LESS than $20/sq. $1/sq for cap nails, $5/sq for felt & $5-10/sq for labor. $500 max for house.

It's a misconception that the felt acts as a waterproof barrier......It's purpose is only to add life to the shingles by not letting the tar base saturate into the plywood. Some people don't use felt and the roofs dry out, crack and fail faster than those that use felt......30# has for saturaterd asphalt and will aid the roof in lasting longer.
