When we are not the Main Contractor we are quite happy to work as a sub-contractor, such as in this case. Close liaison and good communication with the Building Contractor employing us was essential to ensure a smooth operation whilst we replaced the roof on this late nineteenth century Church using Penhryn Welsh slates. We had to dovetail all the re-roofing operations, scaffolding etc. into tight windows between Weddings and other services and respectfully down tools for funerals.
