The use of Zinc has become increasingly fashionable in the UK as its popularity has spilt over from the continent. As a roofing and rainwater goods material Zinc holds excellent green credentials along with a lifespan of over 150 years. There are several different types and many different colours of Zinc to choose from, including the Pigmento range (from VMZINC) which is available in blue, red and green. There are also Anthra Zinc and Quartz Zinc.
- Zinc has the ability to develop its own protective layer called a protective patina, which will self repair any imperfections or scratches that may otherwise appear. In other words Zinc is maintenance free.
- Zinc is laid in strips meaning that it can be folded to fit the most complex of shapes and designs from a roof pitch of 5 degrees to vertical. Zinc is the perfect material for innovative architectural design.
- Considered as a superior alternative for residential and commercial roofing, Zinc outperforms other materials with its combined longevity and stylish aesthetic appearance, which for many justifies its initial cost.
- Kingsley specialist roofing Ltd also highly recommend choosing Zinc because it is a recognised sustainable material that can be constantly recycled. The recycling process uses less energy than the mining process of other metals. So Zinc is green!
As one of the oldest materials used for covering roofs Copper is a proven and malleable material that is a hugely popular choice. Copper begins in a bright natural state which darkens to a rich brown and like Zinc, with time Copper develops its own natural patina giving its green or blue appearance. Many of our customers prefer the patina to be visible more quickly without having to wait for the natural patination process to take place, in such a case we can provide a pre-patinated Copper. Once installed the pre-patinated Copper takes on its natural patination process ensuring that protection is maximised.
- Copper material is both durable and lightweight (a quarter of the weight of tiles), meaning it will stand firm against high winds and is also fire resistant.
- The striking green patina that naturally appears within the first few years, gives a great aesthetic appearance.
- Copper can be measured to fit exactly the specification of the roof, cutting down on the wasteful and time consuming process of cutting and trimming material on site.
- Copper has fantastic green credentials, due to the fact it will more often than not outlast the structure that it covers. The Copper can then be stripped and in many cases re-sold to homebuilders and re-used. Installing a Copper roof requires a degree of skill and training and here at Kingsley we are certainly up to the task.
- It can be worked at most temperatures and isn’t affected by cold weather.
- Copper is a trouble free building material ideal for roofing, flashings, gutters, downpipes and most architectural specifications.
- Copper has a very long life expectancy of over 100 years.
- It is 100% recyclable with a high recycled content.
- Copper is Eco-friendly it’s been awarded a BRE A/A+ rating.
- You won’t have to clean or look after it as it is self-cleaning.
- It can be ideal for non-ventilated constructions and is well suited to all enviroments.
With the cost of maintenance continually on the rise it’s important to choose the right material. It has a great resistance to corrosion, a smooth finish, and requires minimal maintenance in the long run.
Stainless Steels resistance to corrosion is a result of it containing 10.5% Chromium giving it an inherent ability to protect itself. The Chromium reacts with oxygen surrounding it and forms an invisible protective layer (chromium rich oxide). Should the layer be damaged it will naturally rebuild itself if oxygen is present.
The typical thickness of Stainless Steel is lower than most other metallic roofing materials due to its effective mechanical performance. On completion of a project the overall weight will be lower providing a more cost effective and lighter structure.
Stainless steel is 100% recyclable. On average Stainless Steel has 60% recyclable content. Approximately 40% originates from ‘end-of-life’ products and about 60% comes from manufacturing processes.
Further Cutting your costs:
Stainless Steels resistance to corrosion extends to the effect of moisture underneath the cladding, meaning a ventilated support is not always necessary. This gives the option of a less costly warm compact roof.
Stainless Steel has excellent heat reflecting properties due to its reflective smooth service.
Stainless Steel flat roofs can provide an excellent underlay for green roofs due to its resistance to roots and algae. A good drainage layer cutting between the organic material and the stainless steel combined with the correct stainless grade provides the perfect platform for an all year round garden.
Resistance to fire:
A melting point of around 1500 degrees C (much higher than other roofing materials) means its resistance to fire is excellent.
Workability during all weathers:
Successful construction of stainless steel is far less dependent on the weather because it is not sensitive even when exposed to severely low outdoor temperatures. This is partly down to the Stainless Steels that are most frequently used being easy to form and join.
