Still don't see how a tear/hole in the felt changes how ater runs onto the sofits, I think that's a different (but real) issue - unless - you're saying the water moves from the outside of the felt onto the inside/underside, tracks all the way down to the sofit?
Like the look of those drip strips - is there a name for them, could do with some on my front roof?
