ABOUT ROOF SLATE & SLATE ROOFING
Roof slates are derived from fine-grained sand-free clay sediments. Roof slate has characteristic cleavage planes which were produced when the clay was metamorphosed. Roof slate can be split into thin section (typically 4-10 mm for roofing slates) giving a natural riven finish. Roof slate may also be sawn, sanded, fine rubbed, honed, polished, flame textured or bush hammered.
Roof slate is available in a wide range of colours, including blue/grey, silver grey and green roof slate from the Lake District; blue, green grey and plum red roof slate from North Wales; and grey roof slate from Cornwall. Roof slate is imported from Ireland (grey/green), Canada (blue/grey), France (blue/grey) and Spain (blue/black). Spain is the world's largest producer of roofing slates.
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.
