The installation of the slates continues slowly but steadily. According to the contractors, the slates we had bought and recycled from an old farm 6 years ago are very good quality and some of them unusually large. They have just laid down a 1.6m-wide slate which is very rare.
Unfortunately, there will not be enough slates, especially the large ones and we are going to have to purchase more from a different source. Because the North side of the roof is fairly large and particularly long, larger slates are better, especially at the bottom of the roof where there will be a higher volume of water to drain.
The contractors had started to install the slates on the front of the house and recently switched to the back. The back has a North-exposure so starting on this section would avoid having to work on it later when the temperature cools and the winds start again.
