This is a traditional technique involving timber battens and capping strips. The sheets and long strips are held in place by a batten clip supporting the peripheral upstands. The capping strips are placed in position by overlapping, thus ensuring that the roof is water tight. This technique creates an impression of strong, conspicuous contours and is often used for its shadow effects and urban character.
