Have a 10 year old house, interlocking concrete roof tiles.
Lifted some tiles to feed a cable through yesterday and the felt is not supported between the bottom lath and the facia leaving a sag. In one place a tile is cracked and water has collected in the felt where it sags.
Should there be a board under the felt to stop the sag and ensure that the water runs off rather than collecting?
