Copper faltsevoy roof - device and installation do it

A few centuries ago, builders realized that metals are excellent for arranging roofs, as they perfectly protect the building from atmospheric moisture, sunlight and cold. The low anti-corrosion properties of this material have always been considered a metal roof problem. This drawback, which significantly reduces the service life of the structure, is devoid of a copper folded roof, which, upon contact with water, does not change its properties or appearance. Proof of this are ancient palaces and castles, the roof of which, covered with this noble material, is perfectly preserved and does not require reconstruction even after 200-300 years. Experienced craftsmen say that the copper coating is always outliving the owner of the house. In this article we will tell you what the price for this roofing material depends on, as well as how it is mounted.

Material properties

Copper is an inert metal that does not enter into oxidative reactions with oxygen, and therefore does not corrode. The roof of this material has a light weight, resistance to temperature changes, the effects of precipitation and other adverse factors. The lifetime of a copper roof is 100-200 years, however, stories are known examples when it served much longer. The folded roofing device is made using copper sheet, produced in the form of rolls with a width of 0.6-0.7 m and a thickness of 0.6-0.8 m. There are the following types of copper:

• Oxidized. It is a metal that, with the help of special compositions, is oxidized in production, acquiring a reddish tint. Under natural conditions, copper is oxidized in 5-7 years.
• Patinated. Patina is a film that covers copper, protecting this metal from further oxidation. It gives the material a noble greenish tint. Copper is aged with special reagents. Ordinary copper is oxidized to patinated for 15 years of operation.
• Tinned copper. This type of metal has a dull gray color, which gives it a coating of tin. The price of tinned copper is higher than other varieties of this material.

Note! Experienced roofing masters advise using patinated or tinned copper to make a folded roof, since these types of material, which have undergone oxidation with reagents, have a long service life, while their price is only 20-30% higher.

Folded roof construction

The device of a faltsevy roof from sheet copper begins with production of pictures. A picture is an element of a roof, whose width corresponds to the width of a roll of material, and the length of the length of the slope. The edges of the picture are bent in the shape of the letter "g", forming a fold, a special way of tight connection of the sheets. Professional masters connect the pictures with a vertical double or single fold with the help of a special tool - a frame. Such a device, devoid of horizontal joints, allows to obtain a reliable waterproofing coating. The roofing pie of a copper faltsevy roof consists of a vapor barrier layer, heater, waterproofing, and also directly roofing material.

Additional sheets, details of the drainage system: gutters, pipes and funnels are made of copper sheet left after cutting the paintings. For fixing the roofing material using roof clamps (movable and fixed) and nails from the same metal to extend the life of the coating. With proper installation of the roofing pie using copper has the following advantages:

1. Long service life. As a rule, the folded roof of copper sheet does outlive its owners, since the lifetime of this material is 100-200 years.
2. Corrosion Resistance. Copper after the formation of patina, giving the metal a noble patina of antiquity, does not enter into an oxidative reaction with water, therefore, no rust appears on it.
3. Presentable appearance. Copper roofing with seam fastening effectively complements the house in any architectural style, eloquently speaking of the high status and wealth of the owner, as the price for this coating corresponds to its high performance characteristics.

Note! Manufacturers produce ready-made paintings with self-snap seam fastening, which significantly reduce the time spent on installation, as well as the total cost of roofing work.

Rafter preparation

The roofing pie of a copper roof with seam fastening is laid on the rafter frame. Med is a flexible material subject to thermal expansion, therefore it requires special accuracy in calculating and assembling the rafters system. Inaccurate calculations or misalignments in mounting lead to skewing and deformation of the coating. Installation of a copper faltsevy roof is carried out on the basis meeting the following requirements:

• To build the frame, high quality wood is used, as it must be durable, withstand the weight of the roof.
• The wooden elements of the frame before assembly are impregnated with antiseptic and fire-blocking compounds 1-2 times.
• A waterproofing material is placed on top of the rafter legs. A diffusion membrane is used as it protects the frame and thermal insulation, which is necessarily included in the roofing pie, from moisture and condensate penetration.
• The crate for flooring a folded roof of copper sheet is made solid to avoid deformation of this flexible material. It is made of edged boards impregnated with antiseptic.

Note that the thickness of the section and the distance between the elements of the frame of the folded copper roof are calculated so that they can withstand their own weight, the weight of the roofing pie, as well as the intense snow and wind loads.

Mounting technology

The marking and cutting of copper sheets for the manufacture of paintings produced on the construction site using a rolling machine. Thanks to this technology, the amount of waste material is reduced, and the price of roofing works is also reduced.In addition, the individual production of roof elements will reduce or eliminate the horizontal joints between the sheets, increasing the tightness of the coating.Mounting technology фальцевой крови заключается в последовательном выполнении следующих операций:

1. On the box of the house, a mauerlat and a truss frame of wood impregnated with an antiseptic and fire-blocking compound are installed according to the calculations and design.
2. The building was opened with strips of waterproofing material with an overlap of 10-15 cm, fixing it with a construction stapler.
3. Mounted solid crate of edged boards, treated with antiseptic compounds, flame retardants.
4. Install the eaves, fasteners for the elements of the drain.
5. Billets of copper, bent around the edges set on the slope of the roof. Pictures are fixed on the crate with the help of copper clamps. Skilled craftsmen recommend alternating mobile and fixed fasteners to compensate for the thermal expansion of the metal.
6. A small rebate, whose height is 25 mm, is inserted into a large, 35 mm high, and then bent. In this way, a double standing seam with a height of 23 mm is obtained, which is considered the most reliable method of connection.

Note! You can start laying copper paintings from the corner of the slope or from the middle. To get an aesthetic, symmetrical coating, you need to start flooring roofing material from the center of the slope.
