Carpenter Steve Jackson chose Westminster Slate, the latest tile from Redland when he built his own four-bedroom house on a plot at Christchurch in Wisbech, Cambridgeshire.

A large format interlocking clay tile, the Westminster Slate has a hidden cut-back interlock and a finely tapered leading edge that makes it appear exceptionally slim. It’s raised nail holes and custom-engineered head enables it to be installed on roofs with pitches as low as 17.5o.

Although it offers the quality and good looks of traditional clay tiles, the Westminster Slate is more cost-effective because – thanks to its size and interlocking design – only 10 tiles are needed per

square metre, rather than 60 traditional clay plain tiles.

Available in three classic colours – City Black, Cardinal Red and Old College Red – the tiles can be laid on a variety of roof configurations.

Hips and ridges are available in both Half-Round and Universal Angle, and in permutations to allow either a colour-matched roof or the contrast typically favoured on slate roofs.
