Old and New
Zinc, like copper, is a very long lasting material: in a rural environment this can be up to 100 years needing no maintenance or treatment throughout its lifetime, although good roof ventilation has to be ensured when designing roof construction for this to be achieved
It develops a protective patina which will self repair any imperfections or scratches which may occur.It can be laid on pitches from as little as 5 degrees and up to vertical cladding; because it is laid in strips it can be easily adapted to any shape including curves and form complex shapes.
The main difference from copper – and a reason some architects prefer zinc – is its colour stability. It is available in a large range from black to red with the natural grey patina colour being the most widely used, but all of them will retain their original colour throughout their lifetime.
