Today, the roof overlap with copper is increasingly used as an architectural decoration of structures. Despite the fact that the material is quite expensive, such overlapping is gaining popularity due to easy processing of the material and a long operational period. In addition, the roof of copper is unusually beautiful. The flexibility and flexibility of the copper makes it possible to lay it as an overlap on the roof of almost any complexity.

Materials for roofing from copper
To arrange the overlap, copper is mainly used in rolls, the width of which varies from 600 to 700 mm, and the thickness is from 0.6 to 0.8 mm. Stacking copper coils is more profitable than copper sheets.
At the formation of roof fragments of waste remains less, and their installation on the lath significantly reduces the number of joints with rebated overlap. As a consequence, the copper seam roof has a small number of joints that has a very positive effect on the tightness.
There is an option of overlapping from a checkerboard or shingles made of copper. Here, there is no particular difference in which format to buy copper (in a roll or in sheets). If you want to make the roof in this way, the main emphasis is on the accuracy of the dimensions of the copper material.
That's why, it's better to take a master with you to purchase, which will cover it. It is he who can choose the right width of the source material, the selection of optimal parameters will help to avoid many problems that often arise during the work.
Fragments of the overlap are made on a bending machine or with a stamp. In the process, a specialist-roofer, combines them together. Copper roofing, the price of which is quite high, still attracts the attention of developers with its unique beauty, it quite reasonably refers to the category of elite.
The cost of production and installation of rebated roofing is an order of magnitude lower, so it is used much more often.
Marks of copper used for roofing works
To equip the roof overlap, copper is suitable for such brands:
- M1 - it includes 99.9% of copper, it is made only to order, it costs almost a quarter more than all other brands;
- M2 - contains a slightly smaller percentage of copper 99.7;
- M3 - the percentage is 99.5.
The free sale of the brands M2 and M3.
The choice of copper for the roof is rich enough, it is divided into types that differ in properties and appearance:
- Classic - copper, not covered by the composition, leading to artificial aging, subject to gradual color changes under the influence of natural phenomena;
- Oxid - copper, which passed the aging procedure at the factory, initially has a brown tinge, and after a certain time it changes color to green;
- Patina - undergoes the process of aging in production, the outside is clad with a patina of noble brown-green color, and the lower side has the color of ordinary copper;
- Coated - does not change the color gamut throughout the operational period due to two layers of protective coating;
- Gold - an alloy of copper, in which a certain amount of aluminum is added, it is golden colored, which, under the influence of the surrounding environment, becomes matte over time.
In the construction market, if desired, you can buy tinned copper. Its composition is enriched with tin, which adds to the material a gray tinge and metallic luster. The properties of such an alloy do not change, they remain similar to copper.
Pros of copper overlap
The initial cost price of equipping overlap with copper is significantly higher than that of others. But, a fairly long operational period and uncomplicated care, in the end, show its profitability.
The most basic, in copper overlap is a long service life (more than a century). In addition, the plus can be called external attractiveness. The roofs of copper are very colorful and have a lot of color variations.
Also, all kinds of copper roofing are environmentally safe. The material is natural, therefore, the allocation of any harmful compounds to the atmosphere is completely absent and therefore poses no threat to either nature or humanity.
Still worth noting the corrosion resistance. Patina, formed on metal, unshakably protects the surface from the harmful effects of atmospheric phenomena, thereby increasing the resistance to wear of the entire roofing structure as a whole.
Do not forget that the copper material has a high degree of resistance to inflammation. Metal does not deform and does not burn even at a temperature of +150 degrees.
The softness of the metal gives an excellent opportunity to bend the material into the desired shape.
Immunity to low temperatures allows overlapping of copper even in areas with long and cold winters. Good thermal conductivity saves from deformation during sudden changes in temperature.
Experts advise to install on the copper roof cable heating. It completely eliminates the problems with ice and icicles.
Simplicity in the care, that is, complete absence of need, in the process of exploitation, in the processing of any compounds. This, in turn, reduces maintenance costs to zero. The only thing that you need to do on the roof is to clean up the garbage from its surface from time to time, for example - fallen leaves that were brought by the wind.

Mounting of copper roofing
Professionals are advised to make a copper roof only in those cases when its slope is not less than 16 degrees. The system of support for overlapping is better made of coniferous wood, pre-treated with fireproof and antiseptic composition.
The base for the copper overlap must be solid. You can make it from waterproof plywood, boards or bars. This type of roof, without fail, requires the installation of a ventilation system.
Otherwise, hermetically made overlapping will make it impossible for the structure to "breathe". Arrangement of ventilation consists in design of special apertures, due to which the air movement will take place.
Entrance holes are made in the lowest place of the roof, and the weekend, in the highest place of the ridge.
Beginning of installation, first of all, do eaves, it will be necessary to mount brackets and install gutters.
In the event that the roof construction provides for the development of the land, then they should be done first.
Installation works begin with the underlying layer, roll materials are used for its arrangement. They are stacked observing the parallel to the ridge, the strips are laid with an overlap of not less than 8 cm. For fixing the strips, roofing nails are used.
It should be remembered one feature, the seam roof, the device of which we manufacture should be constructed exclusively using copper elements, copper should be:
- clamps for fastening, carnations for them can be copper or made of high quality stainless steel,
- brackets for sewer pipes, pipes themselves,
- drain gutters and funnels,
- fences and other elements by which the roof can be decorated.
Screws, if they are required during the installation, should be used in stainless steel.
To avoid problems with seasonal deformations of roofing material, it is customary to use a combination of rigid and movable clamps.
To achieve an ideal symmetry, the patterns begin to be laid from the center, sometimes they are laid from the corner.
To connect the fragments of the copper roof using double standing seams, their height should not be less than 23 mm. For qualitative fixing, it is required to use 4 clamps on each square meter of the roof, a step from 400 to 500 mm.
Fastening of the area along the perimeter of the building should be done in a smaller step, about 350 mm.
Technology of copper roofing, styling options
The technological process of laying can be of two variants: traditional and modern. Implementation of the modern version can safely be entrusted even to a specialist with an average qualification. This option does not require special skills and experience, it is very simple and fast.
Traditional overlapping involves laying copper sheets of small dimensions using a single fold.
Laying of the modern version takes place in sheets of a larger size and with a double fold. When installing large sheets, it is necessary to use a sealing machine, which is guaranteed to make the connections sealed. In the end, the coating looks solid and without holes.
The copper roof, if desired, can be equipped with a system for catching snow, a weather vane or a fence. It is important to follow one rule: all fragments must be made of copper.

Disadvantages of copper roofing
Among the shortcomings, it should be noted:
- First of all, high production costs.
- Also, it is not cheap to call the qualified specialists who will lay this overlap.
- The need to arrange noise insulation, as, in hail or heavy rain, the roof will make noise.
- Copper contact with aluminum or iron will lead to rapid corrosion.
But on the other hand, all the shortcomings in excess are compensated for by a rather long and effortless exploitation, elegance, originality, originality and not high demanding coverage to care.
