this question from NH about slate roofing was never addressed so here is my poor response. Although my experience is with tile not slate, and this picture * is not of the valley. Regardless, I have done something similar in a valley, lining it with lead like you saw in the picture and the principle is pretty straight forward, although at a valley the slate would overlap the lead.
