Properly installed, a single layer of 15-lb felt should shed
water in a normal rainfall. However, it is not a permanent
roofing by any stretch. How long was that felt in place
before the rain? If more than a few days, damage can occur.
If more than a few weeks, that's just too long to expect
continued performance.
Regardless, it should NOT leak. If the felt had been down
too long, the contractor should have repaired or covered it.
If not, it was not properly and/or completely placed
originally.
The good news is, you can either correct it or make sure the
building flashings, ice shields, etc., are properly placed
and complete before the actual roofing shingles are placed
(also properly). Also, check the roof sheathing for
unevenness at the joints, unlaminations or curling at the
edges, etc., or other signs of structural diminishment of
the sheathing. Some renailing may be required, but even
then a properly nailed sheathing job should be OK even after
all that leaking. With a sound base, there is unlikely any
damage, and the wet will dry.
(The general contractor or framing contractor usually lays
the felt. The roofing contractor usually does any cleanup
and minor repairs prior to final roofing. If it is major,
expect the roofing contractor to charge you extra. You can
backcharge a like amount to the general. I wouldn't send
the framing folks back up for any other than very minor
repairs or replacements.)
