Its been raining three days and going to rain three more. My roof is leaking and has some major shingle damage from storms. Can I repair it while its raining without causing more problems or do I need to wait until its fully dry?

temp repair with roofing cement, then review the roof's condition and plan on replacing it.

If there is only one layer of shingles, asphalt or fiberglass or organic, you can add a second layer over top. Two or more layers requires stripping the roof before new.

You could do a permanent repair to asphalt shingles in the rain. You do it the same as when not raining....only wetter.

Thanks for the suggestion. I really looking for it. If I have any other issues then I be back to you. I hope both of you don't mine.

If you have standard 3 tab shingles, and only one layer in place, then you can overlay a new roof. If you have more than one layer on your roof, or if your have heavier dimensional shingles, then you will have to do a tear off, and replacement.

I agree with Wes about the rules of shingling.  However, in your case since you know you have leaks, I would recommend that the old shingles be removed so a thorough inspection can be made of the roof deck.  I have found rotted decking when there was no evidence of leaks from below.  I have also found that some of the flashing had to be replaced because of nail holes in the wrong place.

Thanks for the valuable information.
