Drip Mould
A groove or projecting profile on the underside of a projection that forces water to drip clear rather than run back along the soffit to the wall.
On an actual building
It is a very small detail that prevents a very common failure. Without it, water tracks back under a chajja or sill and saturates the wall junction behind it.
What we most often have to correct
That it is decorative moulding. It is a functional detail, and it is routinely lost when a facade is re-rendered.
