Metal tile device

To understand the characteristics and features of the choice of roofing material, you need to know how the roof covering works. The metal tile is created on the basis of rolled steel, which is galvanized. Its thickness is 0.4-0.6 mm, and the manufacturing process itself is based on several stages. Everything is done with special machines on fully automated lines. The desired shape is obtained by cold pressing.

Initially, the required coatings are applied to the steel sheet, including the protection of the steel with a polymer. After that, the roof can be processed with a roller system, which gives the desired shape in the form of a wave. Bending of the transverse part of the wave is also carried out, and then the desired shape of the tile is obtained. After that, the sheets begin to be cut into the required sizes.

The outer part of many variants consists of several layers:

• Polymer coating with the addition of a specific color.
• Primer coat.
• Passivating layer.

The inside is also covered with 3 similar layers. The average roof width is 1.1 meters, and the length can range from 50 cm to 3.65 meters. The longest length that manufacturers can offer is up to 8 meters. With one sheet, buyers can cover most of the roof, which is a definite plus during renovation work. The visually finished metal roof is similar to a natural clay material. The house turns out to be beautiful, neat and attractive in appearance. However, the main problem among buyers is that they do not know which metal tile to choose for the roof, because modern construction sites can offer a large number of options.

Types of metal tiles

Depending on the manufacturer, the metal tile may differ not only in appearance and color, but also in profiling, protective layers, on which the operational parameters depend. You can understand how to choose metal tiles for your home if you know its main types.

PVDF (Polydifluorite)

This tile material is based on polyvinyl fluoride and acrylic, which are combined in a 4: 1 ratio.By adding high-quality pigments, it is possible to preserve its original appearance for many years, and also to protect the roof from the influence of sunlight. The roof of such a product is matte or glossy at the user's choice. At the time of purchase, the material can be distinguished from other types by the designations PVDF, PVDF2. Manufacturers often use a layer with a thickness of 27 microns, which gives a shelf life of up to 40 years.

Pros:

• A roofing material that can be used in any climate.
• High resistance to sun fading.
• Corrosion resistant.

The main disadvantage of coverage is in the cost, which ranges from 430 rubles.

Matt polyester

The surface of the tiles covered with matt polyester does not have a glossy sheen due to the inclusion of Teflon in the coating. This type can be an alternative for covering the roof of a house, the owner of which does not like glossy metal tiles.

Coating symbol: MPE, MatPE, PEMA, Matpol. Layer thickness - 35 microns. The good appearance of the tiles is maintained for 15 years.

Pros:

• The optimal cost, which is for 1 sq.m. is 290 rubles or more.
• Nice appearance.
• High resistance to sunlight, which is more than glossy type.

Minuses:

• A small selection of colors.
• If the transportation or installation work is inaccurate, then there is a risk of scratches and other damages, which are very difficult to mask due to the matte layer.

Glossy polyester

Such material is characterized by a high level of economy and is considered very practical. The type of roofing is the most popular, since about 70-80% of consumers use this type of tile for the roof. Gloss type polyester is used to protect the outer layer and the metal in general. This coating provides optimum resistance to external factors. When choosing, it is possible to determine the metal tile of this type by the PE marking. The layer for protection is 22-27 microns, which allows you to get a service life of up to 15 years.

• The surface is exposed to the merging of sunlight, which causes burnout after several years of use. In about 10 years, about 30% of the color brightness is lost.

Plastisol

This material is based on polyvinyl chloride. The structure of such a tile is relief, visually resembles the structure of leather or wood, which gives an excellent visual effect. When choosing, you need to take into account that the raw materials are suitable only for places where the climate is often cool, with a minimum number of sunny days, and the air is rather humid. It is not recommended to use such a product for southern regions or places with intense summer heat. When buying a tile of this type, you should be guided by the Pl, PVC marking, a protective layer of 200 microns, and if you use the product under the right climate, then the period of operation will reach up to 20 years.

Such a roofing material will allow the owner of the house to obtain a durable roof. The material is considered the most modern, the development was made by Scandinavian experts, which allows it to withstand the harsh climate conditions in the Russian Federation. The surface is semi-matt, therefore it does not transfer solar heat inside the house, and also excludes strong glare. The relief is clearly visible. This product will add prestige to the entire building, but will look restrained. Marked as PUREX for the sales market. The protective layer is 26 microns, and the period of operation is approximately 40 years. This product is included in the premium class, therefore, it is more expensive than many other materials.

Pros:

• Long service life.
• Great appearance.
• Well protected surface from the influence of aggressive external factors.
• Regardless of the thickness of the protective layer, resistance to mechanical stress is one of the best.

The cost of such a tile is 580 rubles or more per square, which can be considered a disadvantage.

Parameters for the selection of metal tiles

It will be possible to figure out how to choose a metal tile for the roof of a house if you know its main parameters. Not only the visual effect depends on the type of coverage, but also the ability of the roof to withstand certain loads from snow, wind and other external factors. It is recommended to know in advance the main characteristics that will help you choose the right product.

Profiling

This indicator helps to determine the external characteristics of the shingles. There are simple models on sale that have a minimum number of bends, as well as complex shapes that help to highlight the relief.

Among the most popular types should be considered:

• Monterrey - the surface completely repeats the classic clay tiles, repeating the waves without sharp parts. This option is considered the most popular among buyers.
• The cascade is a trapezoidal shape with regular edges, visually resembles a bar of chocolate.
• Andalusia - a profile in the form of a pronounced wave, characterized by the need for horizontal installation on the roof.
• Modern is almost a complete analogue of classic tiles, but the edges are sharper.
• Joker is characterized by regular waves with rounded edges.
• Shanghai is an unusual profile shape for metal tiles, which is visually distinguished by a high crest of waves.

Profile and wave heights

When choosing a metal tile, it is recommended to pay attention to the profile height, which will be 1.8-2.5 cm. The higher the value, the better the roof will withstand the loads, but the cost will also be higher.

The appearance of the future roof also depends on the relief. The more complex it is, the harder it is to make roof battens. Often shear waves are produced in steps of 0.3, 0.35 and 0.4 m. Waves are best chosen to be 2.5 cm - this is the optimal height, which gives reliability to the entire structure.

Steel thickness

The overall resistance of the material for roofs to loads depends on this parameter, in addition, sufficient thickness gives the strength of the entire structure. It is recommended to buy material made of steel from 0.4 mm or more.

Roofing material with a thickness below 0.4 mm can be deformed in the meta of fasteners, bends, and deflection will begin under the weight of snow or installers.

Sheet dimensions

Before buying, you should take careful measurements of the roof and decide on the type of coverage. It is important to do the calculation correctly so that at the end there are a minimum of pieces of the roof. Often, the width of the sheets of metal tiles is 1 or 1.1 meters, and the length can be different, more often 2-6 meters.

Colour

This parameter is optional and often depends on the individual taste of each person. Experts recommend choosing a color for the facade of the building and the overall landscape. For southern areas, you should buy light shades to exclude strong roof heating.

Extra options

Based on the above material, we can say that quality and durability depends on many parameters that need to be paid special attention to when choosing, but there are several more important features:

• The thickness of the protective galvanized layer should be from 225 g / m2.
• The best is the protection of fluoroplastic, pural or composite coating with granulate.
• You need to choose goods from those that have been tested by the brand, since this gives a quality guarantee, you can be sure that everything is done on modern and technological equipment in compliance with norms and standards.
• When buying, be sure to evaluate the visual condition of the tiles. There should be no scratches, dents or other damage on the surface. It is recommended to try to push the material with your hand, if deformation begins, then refuse to purchase.
• Product packaging may indicate quality. Conscientious companies try to make high-quality packaging, which keeps the metal tiles intact and saves on additional protection during transportation.

Which metal tile to choose for the roof

In conclusion, you can make a summary of the material presented in the article, which were created by experts. Tips will simplify the choice of roofing material for certain climatic conditions and other needs:

• Tiles with a protective layer of polyester are recommended for houses that are built in a temperate climatic zone, where there is no strong wind, large snow and other weather conditions.
• Plastisol materials are recommended for cool climates where there is rarely a scorching sun.
• For the southern parts of the country, it is recommended to use purex, PVDF or pural. Such coatings allow you to maintain their properties even in strong sun.
• For the central part of the country, pural or polyester shingles should be used.
• If the building is located in places where a lot of snow falls during the winter, you should choose a wave with a height of 2 cm or more.
• Based on the stylistic direction of the house, you should choose the right look for the metal tile. Masters recommend using monterrey or a cascade for classic buildings, if the building is made in an east direction, shanghai tiles will do. Modern houses, especially with a large number of windows, can be complemented by a modern surface.
• The color will be no less important, for example, a red or green roof is perfect for wooden buildings, and brown tiles will be effectively combined for a brick house.

Using the information and advice described, it will be easier for any buyer to decide on the right choice, and the service life of the entire roof and its operational characteristics depend on it.
