11 x 7's

Matching like with like can involve the use of 11"x7" clay roof tiles which are available in the Dreadnought Classic range of colours.  English Heritage are keen that new rather than old 11" x 7" tiles are used to reduce theft from existing roofs.

Technical Info

Dreadnought Tiles conform to BS EN 1304:2013 and should be fixed in accordance with BS5534 "Slating and Tiling" part 1 & 2 and BS8000 Part 6.
Frozen-Icon2 webFreeze Thaw Standards require plain clay tiles for use in the U.K. to withstand at least 150 freeze / thaw cycles under method E of European Standard EN 539-2:2013.   At Dreadnought Tiles we regard this as too low for our climate and we therefore test our tiles to withstand in excess of 400 cycles.

11 x 7 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.
