Whats the crack

Any thoughts on the state of this roof? I’ve been told that the tiles should’ve been cut flush to the wall, there is some damp on the chimney breast in the house. But there’s no ventilation on it either. I’m thinking it could be a quick fix of putting event on the chimney breast and having the tiles cut and levelled properly?

Thanks guys you’ve put my mind at rest. Any thoughts on the roof? I’ve been told that the tiles should’ve been cut flush to the wall, there is some damp on the chimney breast in the house.

Thanks for the info. It’s a new house purchase you see, but I didn’t want to buy it if there’s any subsidence or major structural issues. So I’m not too sure about the steel lentil. It sounds like it’s not a big concern at the minute then?

Was just wondering if I could ask if this crack is a concern. It seems to have been repaired with a relatively soft filler a bit similar to a test texture of mastic. i’ve been told it may be due to the house having had old wooden lentils that have now been replaced and filled use in packers which may have moved slightly? i’m not sure about the tiles on the roof either? Any help or guidance would be appreciated.
