Repair and installation of copper roofing: patenting,

Copper roofing is very different from modern roofing materials in terms of price, performance, service life or appearance. It is considered a roof covering of premium class, the price of which is justified by high quality and unique design. The installation of a copper roof is a technologically complex, labor-intensive process that only a true professional can handle. For the roof of this material, a multilayer “roofing cake” is created, lightning protection is established, as well as heating, which facilitate its maintenance. In this article we will tell about the features of the construction of copper roofs.

Types of copper

Copper is a lightweight, soft, wear-resistant, corrosion-resistant metal that has been used for roof coatings for more than 6 centuries. It is distinguished from modern roofing materials by its high price, long service life, which exceeds 200 years. There are 3 types of roofing copper:

• Classic. Classical copper has a bright reddish-yellow hue, which persists for 7-10 years of service. The price for this type of metal is slightly lower than for patinated or oxidized coating.
• Oxidized. Oxidized copper is formed in a natural way from the usual under the influence of oxygen for 7-10 years. It has a rich reddish-brown hue. The price of oxidized copper is 1.5 times higher than the classical one, since it is aged artificially under production conditions under the influence of reagents.
• Patinated. This term is called copper, patinated in natural or industrial conditions. Patina is a greenish oxide film that forms on the surface of a copper roof after 15-20 years of operation. The price of patinated copper is very high, however, it is valued for its high anti-corrosion properties.

Important! The copper roof will serve the declared 200 or more years only provided that the roofing pie into which the special substrate surely enters will consist of complementary materials, high-quality heating of slopes and lightning protection will be mounted. Installation of copper roof is very expensive, as the price is the cost of purchasing metal, auxiliary materials, as well as the cost of work.

Advantages of copper roof

Neither the indecently high price nor the complexity of mounting the roof of copper sheet does not deter developers from its construction. The coating of this corrosion resistant material immediately demonstrates the high status of the homeowner. If you mount the roof according to technology, it demonstrates the following advantages:

1. A light weight. The folded copper roof weighs only 5.3 kg / m2, and the tiled 6.5-7.5 kg / m2, so the roofing pie is quite light, it does not overload the roof system.
2. Wide range of temperatures. Copper pressure deformations withstand temperatures in the range of -70 / + 150 degrees, which allows the installation of copper roof in all climatic zones.
3. Corrosion Resistance. From the effects of water, copper roofs do not rust like other metal coatings, but are covered with a noble patina, which only improves the appearance of the house.
4. Tightness. The roofing pie of the copper roof, which necessarily includes the substrate, heating and lightning protection, reliably protects against leakage.

Important! Roofing pie under the copper coating, which includes a special substrate, consists of many components, so the price of the construction of this type of roof can result in shock. The cost of 1 square meter of roofing with the installation work is 4-6 thousand rubles. In addition to these costs, the roof will need lightning protection, heating and installation of snow guard.

Types of copper roofs

For the construction of the roof using roll or sheet copper with a minimum thickness of 4 mm. Roofing technology of this material may vary significantly. The final cost of the installation, the time spent on construction, and the roofing pie depend on the method of installation. There are 2 types of copper roofs:

• Seam. Faltsev is a roofing coating of copper, consisting of copper paintings, connected with a double or single lock, fold. The paintings are quite large, so installation and repair of a copper roof of this type is faster and easier. The vapor barrier, insulation, waterproofing, crate and special substrate preventing damage to the soft metal are included in the roofing pie of the folded roof.
• Tiled. Such copper roofs consist of small-sized particles, shards. These shards are placed in an overlap and are interconnected by a lock located at the top of the element. Depending on the shape of the parts, the tiled roofs are scaled and checkered. The roofing pie of such coatings is distinguished by a high weight, it includes a moisture-proof substrate that prevents leakage inside the roof frame.

Experienced craftsmen claim that lightning protection is an indispensable element of a copper roof, as it accumulates significantly static voltage and can also become an object of discharge in a thunderstorm. Heating is mounted to prevent icing and deformation of gutters with temperature drops in winter.

Copper roofing device

Developers often do not understand that heating, snow guard and lightning protection are mandatory roof elements with a sheet of copper, on which it is not worth saving. Only the presence of these devices make roof operation more efficient and safer. To increase the service life of the roofing and delay the repair of the copper roof, we need:

1. Snow traps. The metal-coated roof is slippery and smooth, so ice blocks and snow masses easily roll off, even if it has a small slope. To prevent spontaneous gathering of snow from the slope, install snow-blocking fencing.
2. Heating. When snow melts, ice build-ups and icicles form on the eaves of the roof, which can lead to the breakage of gutters and blockage of drainage work. To protect the roof from these negative phenomena, mount cable heating roof along the overhang.
3. Lightning protection. Friction and static electricity arise between small particles of dust and the metal surface of the roof. If the charged roof is accidentally touched, a person may receive a strong electric shock. In addition, lightning protection prevents lightning from entering the house.

Please note that for copper roofing it is necessary to install auxiliary and additional elements of the same material. Therefore, it is better to purchase all the components required for installation from one manufacturer so that they are of the same thickness, quality and shade.
