Query about lead flashing on repaired roof

[dbrb2]

A quick query related to roofing on an old victorian property:

It has a lean-to extension containing the kitchen. The exterior wall has always been rendered, with a bellcast just above the tiles where the render stops.
The leading and bellcast was replaced recently - and the lead flashing was run up behind the bellcast rather than being chased into the wall iteslf.

How much (or should) I be worried about this? The roofer is adamant this is fine, since the bellcast is covered in render and there is no route for water to get behind the flashing.
Given the state/age of the brickwork, and the fact there was no pre-existing chase, I think he was nervous about cutting a brand new chase (and the legacy flashing wasn't in one either)

I've spoken to another roofer, who didn't have any "skin in the game" - nor did he know the original roofer, and he feels that this will be fine. I hope he's right

I’d be inclined to agree, personally I would have chased it into the wall as a precaution against the render failing but a) that is belt and braces and b) if the render has failed enough for that to become an issue then you’ll probably have bigger problems to worry about anyway, so reckon you’ll be alright

Thanks! That is what I was hoping, and it sounds reasonable to me as well!
