The main things that looks like Roman building material are horseshoe
field/land drains. These imbrex shaped suckers have had me on the hop a
couple of times (especially small fragments where you can't get a good idea
of the shape), but manufacturing methods and a very refined fabric normally
give the game away - as would any 19th century copies of Roman roofing.
Checking out 19th century trade/business directories may also help with this
Some useful Publications:
Harvey N, 1987. Fields, hedges and drains Shire Album 21
RCAHMS, 1993. Brick, Tile & Fireclay Industries in Scotland
There's also a super display of field drains at the Yorkshire Museum of
Farming at Murton, just outside of York.
There's the outside possibility that it's 12th-13th century curved and
flanged roof tile:
A G Vince, J E Pearce & K H Armitage 1981, Early medieval roof tiles from
London, Antiq J, 61, 359-62
Garside-Neville S, 1995. 'Tile File - Curved and flanged medieval roof
tile', Interim: Archaeology in York, Summer 1995, Vol 20, No2, 31-34

Hope this helps,
