For many centuries, architects designing the most important public buildings – the Town Halls, Courthouses, Police Stations, Schools and Churches – have understood the importance of making a statement of quality and permanence. They knew then that the choice of Burlington blue/grey and Westmorland green slates would offer a long lasting and aesthetically appropriate solution for their projects and these materials are still available today, in the same traditional formats, for the maintenance and replacement of the original roof coverings, offering the same longevity and value over the next phase of the life cycle of the project, and maintaining and protecting the buildings original vernacular.
