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.
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.
Freeze 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.
