The picture used today is one I took at Lullworth Cove and shows the way local roofs close to the sea front are detailed with slate used at the lower edge and clay on the upper areas.
The CPD is to understand why, first stop is to understand the wind pattern and the vortex created by the wind as it flows over the edge. plus the distance the stone projects beyond the wall face.
A lot of the older roofs in the area are detailed the same, some have just two courses, others like this roof at least half the roof is covered in Stone slates. This Wiki site notice has some interesting notes on the subject.
In some parts of the country, stone eaves were used as a bedding for the thatched eves, helping to stop bird or animal attack, so maybe these roofs were retiles rather than thatched this one might well have been originally fully dressed in stone slates and cheaper tiles used as they needed replacing. This useful pdf has more on the subject.
