Here at Cardinal Slates we've been perfecting the art of reproduction slate manufacturing since 1994. Whilst renovating an old barn Richard Parsons, founder of Cardinal Slates, realised that there were no truly perfect copies of Cotswold roof slates on the market. From that moment on Richard's desire has been to create an unrivalled copy of Cotswold slates. Our unique method of casting these reproduction slates in vertical rubber moulds enhances their strength and allows them to vary in shape in three dimensions so that they have a pleasing irregularity.
