Morning all

I'd like your advice on the correct repair procedure. The roof is leaking near the flashing (ridge detail, see 1st image). The flashing itself appears to be undamaged. The only visible damage (without lifting the flashing) is the mortar around the ridge appears to be cracked.

The leak is toward the right in this image:


A closer view of damaged mortar:



The other side of flashing. I'm aware of the chipped tile! The flashing sits well below this chip so I'm hoping that's not relevant at this point:


Would a compound like this be suitable to patch up the cracked mortar, or could someone recommend a better or more suitable product?

Would I need to lift the flashing to repair the mortar below? It would mean chipping out a tile that is being down the flashing from above.

Or something else entirely! Any good advice appreciated.

Many thanks

Hi ivanrhyn
Sticking gung into gaps in a tiled roof is seldom successful. You really need to lift the tile on top of the flashing to see what is going on. The underslaters felt should provide an inherently waterproof roof so you may have to remove more tiles to correct the problem.

Sound advice stoneyboy. Sounds like a better weather job then ;)
