Leighton Buzzard’s town centre streets — High Street, North Street, Lake Street and the conservation area around All Saints Church — contain Victorian and Edwardian brick properties under plain clay tile, Welsh slate, and in some cases original grey Staffordshire blue slate. These properties have ageing lead valley and flashing details and, on the older stock, original lime mortar chimney pointing that has been eroding for over a century. The town centre is a Conservation Area and Bedfordshire South planning constraints apply to material choices on listed buildings.
The large post-war housing estates of Leighton Buzzard — Vandyke Road area, Linslade across the Grand Union Canal, and the newer Leedon and Heath and Reach fringe development — have concrete interlocking and concrete plain tile roofs from the 1960s through 1990s. Nail sickness is the dominant repair issue on the older 1970s stock. Leighton Buzzard’s free-draining sandy soil means ground moisture is less of a factor than in the clay Vale, but the more open position north of the Chilterns creates higher average wind exposure than Aylesbury.
