Dreadnought Classic Staffordshire Blue clay tiles produce a striking and unique coloured roof. The varied texture of the handformed tile adds character. These tiles are justifiably popular for self build homes and churches. Following a 25 year gap Dreadnought have re-launched this tile made using the same clay, care and delicate kiln control that is synonymous with a Dreadnought.

Dreadnought Tiles are a British manufacturer based in Staffordshire where they have been manufacturing clay roof tiles using locally sourced Etruria Marl Clay for over 215 years. Etruria Marl (Staffordshire Clay) roofing products have unrivalled strength and durability (it is also used to make Staffordshire Blue Class A Engineering Bricks). All Dreadnought colours from blues, brindles and browns to reds are generated without the use of artificial stains or coloured sands; instead the colours are the product of careful control of the kiln atmosphere. This natural quality, which creates subtle colour variation within each tile, gives a unique quality to the Dreadnought product that enhances the appearance of any roof.
