Slate repairs, new gutter & re-pointing of failed mortar.
Raking out & re-pointing the failed mortar using Tuck pointing. Part of the reason this mortar failed was because it had been done in Yorkshire Bond A.K.A. Strap pointing which has a tendency to gather water at the top of the bond which eventually works it’s way behind the pointing. This is why as roofers we use Tuck pointing which doesn’t let this happen and therefore lasts a lot longer being more weather resistant.
