St Edmundsbury Cathedral, in Bury St Edmunds, received a grant through the English Heritage Cathedral Grants Scheme, for reslating the roof of its nave and organ chamber.
Border Roofing carried out all the re-slating and the leadwork on this huge project, working alongside FA Valiant & Sons Ltd.
Dr Simon Thurley, chief executive of English Heritage, said: "Cathedrals are the princes of English buildings. A huge amount of work has to go into securing this grandeur and majesty for generations to come. The grants will go some way to helping the custodians of these titans in this task."
