Slate roofs are formed from individual slates, applied in courses/layers and designed to shed rain and prevent water ingress. There are several slating methods, most commonly used is identical sized slates laid in a broken bond pattern and overlapped, other popular methods are random width and random diminishing. The lap is determined by the degree of pitch, wind uplift, and site exposure. Generally the lower the pitch of roof the greater the lap should be, double or even triple lap is required, increasing the slates required per m2. Slate can be cut, holed and trimmed using hand tools, making for fast and safe work when completing the roof. Slates are then either nailed or hook fixed, and both come with advantages and disadvantages.
Slate roofs require little maintenance other than replacement of individual slates that become damaged.

Slate is imported from all over the world, Western Counties Roofing only use leading manufacturers and suppliers.
