	Artificial slates can be a cheaper alternative to natural slate but their longevity is only around 40 years or so. They come in similar sizes to the larger natural slates but are considerably lighter in weight. They are normally fixed with 2 nails per slate, centre nailed, and a further fixing is used to secure the bottom edge of each slate to prevent it lifting in high winds or due to thermal expansion.

	Generally, the larger the slate, the lower the roof may be pitched. Also, the lower the roof pitch, the greater the head lap required. The top of the slate is referred to as the ‘head’. Overlap is when one slate overlaps another, whereas ‘head lap’ is when the head of a slate is overlapped by the slate two courses above it. On a slate roof this is the critical overlap and is necessary to prevent water penetration and leakage.		Generally, the larger the slate, the lower the roof may be pitched.
