^ they need to strip back the tiles a replace the felt from above. I've got same issue in our roof in a couple of places luckily it doesn't leak. One day I might get up on the roof and repair it.


You wouldn't think yours would leak lee as it's on a flat section of the roof maybe there's a broken tile on the outside or a missing tile. Or rains getting driven up under the tile by wind.

Are they concrete formed tiles?
