Weatherboarding is the cladding of a house consisting of long thin timber boards that overlap one another on the outside of the wall.
Traditionally timber weatherboarding was used without a finish, relying upon good air circulation and the use of 'semi-hardwoods' which would keep the boards from rotting. More recently weatherboarding has been tarred or painted; traditionally black or white due to locally occurring minerals or pigments.
Weatherboard houses may be found in most parts of the British Isles, and the style may be part of all types of traditional buildings, from cottages to windmills, shops to workshops.
