   Geeze, there must be at least a dozenty twelve variables in that answer...

   It depends on whether you used 15# or 30#, how well nailed it is, how much wind you get between now and then, the quality of the tarpaper,etc....

   I would often get 3-4 weeks out of the old 15# on a roof when nailed right and no major tornadoes, but I have seen times when it didn't stay overnight.

   Its 15#felt and secured pretty well.  We've had some rain but I was also worried about sun exposure.  It'll stay on (not very windy around here) I just wanted to make sure it would still be good when I put the foam on the wall and then the vinyl siding. Thanks

   The main problem you have is if 15# gets wet, it wrinkles to the point that it is difficult to roof or side over. I certainly wouldn't worry about some unseen degredation. If it looks OK, and the wind hasn't shredded it, it's fine.I knew a guy (one of those carpenters who can't work on his own house) who has had 30# on his roof for years. Just changes it every year.

   You'll know soon enough. The cheaper stuff will shrink and the edges curl more. I can recal some that shrunk to about 34" wide after a couple weeks in the sun.But for sidewalls, the sun is not as direct and hard as on a roof. The angle the rays hit it at makes a difference.
   Good luck. But it won't break the bank if you have to replace it.

   we both know it's gonna give up the ghost last week.... 

   Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming<!----><!----><!---->

   It depends on what you are covering up and how important it is to keep dry..

   We used 30# felt over a timberframe covered with prefinished 1x6 maple sheathing. This was going to be covered with sips that were scheduled to arrive in a couple of weeks. For some reason the quality of the tarpaper was poor (How can anybody know this?) and we had failures underneath some of the furring strips.

   The sheathing buckled and we had to spend a couple of days relieving the pressure and renailing the sheathing. We covered the sheathing with Rooftop guard or a similar product. The mistake cost us more than $1000 dollars and defects are still visible from the inside if you know where to look.

   On the other hand we have had 30# felt work to keep space dry for over 6 months. Nothing is totally reliable except the final roof.

   failures under the furring???Was this tacked on horizontaly?
   If so, you should expect water trapped there to find a way in. Furring strips is the poorest way of holding tarpaper in place.RTGII is far better though for roofs. I have had it in place for 5-6 months a couple times in adverse weather situations with no troubles.

   Hey I'm in the same boat its been about 2 wks now. #15 felt some curling but that's about it. It's been thru some rain also. Still have another 3 wks before the siding comes in. I did'nt even think about the felt deterioratng.

     Had 30 # felt up on the west side.Been 2 years on the Oregon coast. Its fine and I just got my permit today for the addition. There is a new fee for permits. One dollar per sq ft for living space and 50 cents for garage etc. This is on top of the regular building permit and you make the check out to the school district. That more than doubled the fees. Oh well.
