Staffordshire blue     

Staffordshire Blue sandfaced clay roof tilesStaffordshire Blue smoothfaced clay roof tiles

This colour has the depth and subtlety of a true blue clay colour which can provide an effective contrast to light coloured stone and brick work.  It is deeper and darker than the Blue Brindle and Dark Heather.

Some companies produce a dark tile by the application of a spray on surface stain, however the Dreadnought range of genuine traditional blue clay colours, with their natural shade variations are obtained through the careful control of the kiln atmosphere that converts the iron content of the clay to blue in the manner of Staffordshire Blue bricks.  A skilled process established by generations of brick and tile makers which is unique to the Dreadnought Factory.

This tile works equally well for contemporary roofs as it does for heritage roofs.  A church reroof with Staffordshire blue smooth tiles won the Best Heritage Roof Award at the 2018 Pitched Roofing Awards and a highly contemporary selfbuild project featuring the same tiles has been awarded Best Small Project at the 2020 Roofing Awards.

This Staffordshire blue clay roof tile offers an alternative to natural slate with the potential to incorporate ornamental elements in the roof.

New roof for St Mary's Bushbury

bushbury 1Bushbury 2

Winner of Best Heritage Roof at the 2018 Pitched Roofing Awards this complex reroof of a Grade II* church has alternating four-course bands of plain and  fishtail tiles in Dreadnought's Staffordshire Blue.   Architect Bryan Martin wanted to match the originals that were fitted back in the 1850's as closely as possible and he felt that the original tiles came from a similar source, and may have even been Dreadnoughts.  A total of 14,250 fishtail tiles and 32,000 plain Staffordshire Blue Smooth tiles were used as well as 2 matching bat tiles (one is just visible in the RH image  above) and approx. 140 300mm angle ridges.  Full details

Winner of a 2019 Victorian Society Conservation Award , this historically important gothic brick building was at risk until it was renovated by the West Midlands Historic Buildings Trust in conjunction with Dudley Council.  The 2 chapels had been derelict for some time and were considered an eyesore.  The new scheme designed by Brownhill Hayward Brown, conservation architects has transformed the Chapels into one building now known as the Thomas Robinson Building and Stourbridge Registry Office.  The work was meticulously carried out by Croft Building & Conservation who used Dreadnought Staffordshire blue plain and ornamental spade tiles together with slotted ridges and bespoke ornamental ridge inserts to restore the roof.

Renovating an old barn and a collection of derelict farm buildings required very careful materials selection and the owner/architects reused as many of the old materials as possible.  Dreadnought's staffordshire blue sandfaced tiles were chosen for the new single storey building as they provided a great colour match to the old handmade tiles that were reused on the renovated 2 storey barn.  Full details
