Cooper Roofing Installation & Repairs Kerry Cork
Copper has been used as a waterproof roofing material since ancient times and can be sometimes seen as greenish roofs and domes on today’s buildings. This colouring is the reaction of air with copper which creates an additional protection against corrosion.
Firstly copper oxide forms, followed by cuprous and cupric sulphide then subsequently the green layer of copper carbonate, called verdigris or patina.
We use tried and tested copper roofing fixings and techniques make copper the ideal trouble-free building material for roofing, cladding, flashings, gutters, downpipes and other architectural details.
Advances in technology and techniques, machinery and fixing technologies have greatly reduced costs, which enables copper to be used in a greater variety of building situations than in the past.
Copper is rolled to thicknesses ranging from 0.5 to 1.0mm, but 0.6 to 0.7mm thickness is usually used for roofing. It can be worked at any temperature and does not become brittle in cold weather. It is available in sheets or strips and is generally regarded as a lightweight covering.
Careful consideration is paid to the design of each copper roof, particularly where complex three-dimensional corners found at chimneys, gullies and valleys, must maintain junction integrity. The complex junction pieces must be carefully patterned and folded tight to ensure a complete seal.
Over the years we have been providing solutions, we have developed custom solutions for nearly every type of situation, as well as the ability to resolve any unique challenge.
There are then two basic fitting methods: the roll baton or standing seam methods. When using the roll baton method, batons are securely fixed to the deck, forming the bays which are a characteristic feature of these roofs. The copper bays are formed to the exact specifications of your roof, and fixed into the prepared bays. Cappings and trims are welted on to provide a watertight seal at all the joins.
Using the standing seam method, the copper is secured to the roof by the means of stainless steel clips, fitted between the upstands of the copper bays, which are then welted together.
