So, with carbon footprint being very important to the project, we recycled slates which we had stripped from council houses through a contract with Renfrewshire Council. These proved to be almost an exact match.  The cast iron gutters were also in a poor state of repair, so DM Roofing and Roughcasting took a sample to a local foundry in Falkirk and tasked them with reproducing the same.

The finished job looked as though no works had been done, which was of course exactly what everyone wanted.
