Aisle Roofs in the early period were merely a continuation of the rafters of the nave. At North Walsham, Norfolk (a tie-beam roof), the tie-beam of the aisle is carried through the wall, forming a corbel for the wall-piece of the nave roof, thus binding the whole together. Aisle roofs were usually simple, intermediate trusses being introduced to strengthen the purlins. When they were gabled they were usually of low pitch, and the hammer-beam was rarely introduced for these. New Walsmingham Church (G) and Ixworth Church (F) are good types of aisle roofs.
