Canterbury tales

Coniston are currently carrying out the five-year project to restore the roof of Canterbury Cathedral.

The Grade-I listed cathedral is a historic landmark, dating back to 1020 and part of a World Heritage Site. The cathedral is often described as “England in stone” as its history is intrinsically linked to the country’s history, and it has been a place of worship for more than 1,400 years.

This milestone project involves the installation of a temporary roof over the nave of the cathedral to allow for the removal of the existing roof. The existing lead that was removed, was recast offsite and reused as part of the new installation.

The existing timbers were subject to specialist repairs using pitch pine, Douglas fir and English oak.

The project is due to be carried out over five years, with a full programme to replace the roof over the nave, adjacent aisles and the roofs over the towers.
