   Not if it is a flat roof .. saw somebody trying that once.....hot tar dont work in the rain too well either (dont ask me how I know that)

   Otherwise, biggest issue is safety, I wouldn't try it, Grandpa died falling off a ladder, roofing in the rain would scare me big time.

   I would not do it, but that does not prove it "can't" or "shouldn't" be done.

   1) Safety issues already raised.

   2) Somehow it does not make sense to me to seal up a bunch of water between the felt and the shingles.  Where is it gonna go? How long is it gonna take to get there?

   I would wait until the felt is at least visibly dry.

   That might depend on your climate and why you ask. I must have done it a couple hundred times. It also varies according to whether it is a re-roof or new and by what kind of shingles they are - wood or composition.

   It is not primo best practice, but there are climates where no roofing would ever happen if it could not be done that way.

   I would choose not to roof over weet plywood, so to avoid that, I plan strategy such as to always have it covered immediately as it is laid.

   It does no harm to have a small amt of moisture between the underlayment ( whether tarpaper or the advanced underlayments) and the shingles, But shingling in a downpour is not smart for other reasons anyway.

   Say more about your situation for better advice

    I agree Piffen,

    take monday,oct. 9th

   78 degrees---not a cloud in the sky----guys working shirtless

   Rain is expected Tuesday night,with monsoon beginning weds.

   tuesday morning----no rain on radar--- small area remaining---so we should be done by noon----------

   tear-off side one---felt it in and 2 guys start shingling while I flash the chimney

   2 remaining guys start tearing off side #2---------about 10:15 I think to myself" is that rain I just felt---yup---starting to drizzle

   One of the guys shingling---goes over to help the 2 tear-off guys finish up/sweep off and felt in---drizzle continues.

   I finish my flashing,side #1 gets finished by  one guy while 3 guys shingle side #2

   roof done by 11:30.

   not really the weather i would have preferred------ but once you are committed ya gotta do what ya gotta do

   I usually go YEARS without getting caught like that--luckily this week it was just a little drizzle-----back in august we were doing a house-----perfectly cloudless day---low 90's

   about 3:00---out of nowhere---GULLYWASHER.

   customer actually came outside---and laughed" where the hell did THAT come from---we weren't supposed to have rain for DAYS"----then he actually lined up another job for us right across the street for a neighbor.

   In Florida we could see individual rainstorms marching across the town from a second story rooftop. MAde things interesting! There were times that I have seen it a downpour on the front yard while it was clear sunshine in the back.
   it was here that I was thinking of most of my wet roofing. We would arrive early to try to beat the heat. Almost every job meant sweeping the dew off the tarpaper first thing - new roofs. Because of humidity in seasons it would be ten oclock before the roof was dry. By then it is so hot you are suffering and the roof is almost half done. Then in some seasons thunderstorms hit about one or two oclock PM and give you a nice break for half an hour while you cut ridge and rest up to finish the job post-storm.In Lubbock Texas, you could see a blue norther coming in for a day or two before it hit.In the mtns in CO, a hailstorm could come out of nowhere in minutes or less - in summer
