I am re-roofing and have covered the whole roof with 30# tar paper and
shingled one side of the house.
Yesterday we got a LOT of rain and I had 3-4 leaks on the side of the house
only covered in tar paper. 2 of them was pretty bad and left big spots on
the ceiling.
Should I worry about this and try and find where it was leaking or will the
shingles take care of the leaks when I get them up?

Regards
Mike
