Collingwood blend

Dreadnought Collingwood blend Sandfaced clay roof tiles

Rustic shades of brown

The Collingwood blend of plain clay roof tiles creates a rustic and elegant looking roof of enduring quality. 

It can be supplied on pallets in a predetermined mix with the right proportions of quantities and colours, in machinemade smooth or sandfaced, or in rustic or handmade. When the tiles are pre-mixed, valuable time is saved on site and additional savings are made as waste is reduced when laying.  Also available unmixed.

Available in machinemade smooth/sandfaced/rustic/handmade/mixed/unmixed

This newbuild project involved two oak framed properties, a larger farmhouse and a three bed cottage.  The client wanted a traditional and established look and was keen that the ridges and valley tiles would seamlessly match the rest of the roof.  This would have been difficult to achieve with reclaimed tiles.

Several different combinations of colours were tried in panels before achieving perfection with the Collingwood Blend Because they are natural burnt clay colours they blend perfectly without appearing contrived or artificial.  Just how successful the restoration has been in reproducing the colours and pattern of the original roof can be seen by comparing the new main roof with the original low level bay roofs where restoration will form part of a future phase.  Full Details

Private house, Nr Ringwood

Winner of the CRTC 2008 "Best Self Build" Clay Roof

an award winning Dreadnought Collingwood Blend roof near Ringwood    Dreadnought Collingwood blend roof tiles

This most unusual roofscape design allowed most of the rooms for this contemporary newbuild to centre themselves on the dramatic views without needing the plot space of a linear design.  There are many different facets to the roof which cut in at different angles and there are also an unusual number of verges and abutments . Only plain clay tiles could have achieved the elegant sleek lines of the roof, or could have coped with the small triangular roof areas, which are central to the modern design of this property.  Full Details

Tile Blends Sample Request Form

Please complete this form to let us know which samples you would like.  Due to the high courier cost in sending them out, we cannot supply them free of charge in all cases.

Important: The natural colour of our clay tiles means that no 2 tiles are exactly the same and this is what gives a Dreadnought roof its beauty and character.  Within a single Dreadnought colour, there can be a number of different tones and we will  include more than one tile sample to show you the range of tones you can expect.
