Cement boards on corbelled verge?

[Jeffers_S13]

Renovating an old outbuilding.

Is it usual/best practice/requirement to have cement boards on top of a corbelled verge? if so should they also overhang by the usual ~50mm too?

Can/should I bed the tiles onto the corbelling and do away with the cement boards? as presumably the corbelling's purpose (whilst primarily an aesthetic feature nowadays) was to create the overhang in the first place.

Yes, a verge projection is required, and its functional.

However for aesthetics, you could possibly use slate or clay tiles instead of undercloak if that fits better with the building age.

If clay - use creasing tiles- without nibs and dead flat

Sorry, to confirm, the corbelling is not useable as the projection? And I need boards (or tiles/slate) to proceed beyond that too?

That's right.

Otherwise the brickwork will become saturated with the risk of frost damage and salt staining.
