22.5 degrees is the minimum but I have slated roofs with a lower pitch, I would double felt the roof and use a 18 x 10 or larger slate and give it more cover, ( 5" instead of the normal 3" ) If you go to you local builder merchant they could give you a booklet telling you about slates and there specifications.

Slate Roof Pitch

Roof slate is strong and resistant to acid and frost. It lasts up to 400 years as a roofing material. The minimum recommended pitch for a natural slate roof is 20 degrees under sheltered or moderate exposure and 22.5 degrees under severe weather exposure. Fixing nails should be of copper or aluminium.
