That's what I am trying to decide.Surely better to leave the felt intact.
In the middle about 2/3 of the way down the pic it shows the felt being stretched by the debris which is jammed between the underside of the tile and the felt.What is the pic actually showing in relation to the issue?
I suppose that could be an option. May be a bit difficult to find the right tile to lift.OR ladder and remove a tile and fish it out from the eaves?
