ALM rolled lead focal point for Harrow School rotunda roof ALM rolled lead focal point for Harrow School rotunda roof

One of Harrow School’s most eye-catching features is the rotunda roof of the Grade II-listed Old Speech Room. ALM supplied code 5, 6 and 8 lead and wood roll for its complex refurbishment in which the original splash lap design had given rise to leaks. The wood rolls were therefore radiated to natural falls from a raised tier at the roof pinnacle, forming a hub where roll ends are hidden. Segments of king roll and wood rolls had to be lost and to offset the problem whereby laps appeared too large, the base of wood rolls was rebated and also covered in lead.
