Any roof is naturally completed by certain characteristic elements which become an integral part of the roof itself. Of these, the one which is most visible is the chimney stack, the external part of the flue which today consists of the rationalisation of a traditional feature.
The chimney is constructed as follows: two U shaped slate shelves are fixed to the wall of the stack and are used to support four vertical slabs, joined together by nails or metal ligaments. Inside this box about half way up a fifth slab is positioned, slightly tilted to allow water to drain.
The efficiency of the chimney is ensured by 4 lateral holes in the wall on which the horizontal slab is placed. The pitch of the roof and the brick of the chimney stack are harmoniously joined with slates in order to make doubly sure that the underlying lead apron is watertight.
