I live in the Northeast and we've just had several days of almost
continuous rain. Unfortunately, when I went into the laundry room of
the house today, I happened to notice some water on top of the paper
towel package I keep there. It wasn't much considering all the rain
we've had, probably 1/10 of an ounce if I were to label it, but I do see
the area of the roof that was stained with water. There is no attic in
the laundry room, so I can look right up at the roofing rafters. The
area is quite small and already dry. I quick peak at the area on the
roof itself and I don't see anything suspect, no broken or damaged
shingles that I can see.

This roof is 10 years old and hasn't leaked so far, but I am a bit
concerned, especially since there doesn't appear to be anything obvious.
I'd appreciate any tips as to what I should check and look for. Once
the weather clears, I'll try and post a photo of the area but the
weather is still inclement at this time.

Thanks for any help,
Sam
