For a verge you probably want a little bit of moisture in there to get

Yup. I'd say you want a mortar as flexible as possible and not too
strong. The ordinary mix most roofers seem to use on ridge tiles soon
falls out.

No you want it as strong as hell.

Roofs tend to move a bit. Being timber based. That's why ordinary mortar
falls out.
