Metal tile (abbreviated as MCHP) is a relatively new roofing material consisting of three layers and used for arranging roofs with a slope of 14 degrees. These products are made of cold rolled metal and further treated with a phosphate layer (rust protection), a primer (to improve adhesion to the substrate), a clear lacquer on the inside and a decorative finish on the outside. Due to its low weight (from 4 to 6 kilograms per square meter), as well as metal galvanization in the middle and a special polymer coating, the average service life of this building material can reach 50 years.

The basis of a metal tile for a roof can be:
The main purpose of the roof is to protect the structure from the penetration of precipitation into the interior, to preserve heat in its premises, and to maintain an optimal microclimate. In order to fulfill these tasks, the metal tile of the roof must comply with the State Standards or Technical Conditions.Depending on the climatic zone of the location, the number of storeys of the building, the slope of the roof slope and other characteristics, it is necessary to impose certain requirements on the material in question, which are:
These requirements are basic, the rest will depend on the preferences of the homeowner.
The material in question is a very popular type of roofing, and it has a number of significant advantages:
Find out the thickness of the galvanized layer that protects the entire structure from rust, perhaps by reading the accompanying documents or from the label of the MCHP product. In extreme cases, measurements can be taken independently using a micrometer. To do this, you need to clean the outer layers of the primer on both sides (the fact that all layers are removed can be recognized by the characteristic sound of a knife sliding on metal), and then measure the remaining thickness with a micrometer. Naturally, the whole procedure should be performed on a sample or on an unused part of the roof.
The modern market can offer various types of profile geometry of metal tiles and its depth:
IMPORTANT! The required profile height should be selected depending on the slope of the roof slope and the average annual load on the roof itself. For example, for cold areas of the country, where roofs slope less than 60 degrees, given the presence of strong winds, high profile forms should be used.
The traditional dimensions of sheet metal tiles are:
For ease of installation, these dimensions can be changed independently, which should not affect the reliability of the roof. Trimming the factory models of the MCHP should be done with special scissors, and upon completion of the work, it is necessary to process the bare spots and paint them. The calculation of the required dimensions should also be made based on the parameters of the roof and its angle of inclination. However, the seller's company almost always has the service of individual trimming of profiles, processing of bare joints and the installation itself.
It is preferable to cover residential buildings with a complex roof structure with a durable, wear-resistant and high-quality MChP. This is because a roof with a complex shape will be more often subjected to mechanical stress and the influence of negative natural factors. For a complex roof, a material with a thickness of 4.5 to 5 millimeters in thickness is suitable. Standard arbors, guest houses and small cottages with a shed or gable roof can be covered with a classic type of metal tile with a thickness of 0.4 mm. This option is perfect for any one-story house.
This parameter is responsible for the aesthetic and applied functionality of the material in question. Light shades should be preferred when products are purchased for hot areas of the country. Light tiles will not fade for a long time under ultraviolet rays and will reflect the light as fully as possible.Cold tones should be used for areas with a cold climate, choosing dark shades that can fully accumulate heat.
General design trends for MCHP say that its surface can be:
Gloss is characterized by a moderate ability to withstand negative environmental influences. Its advantage includes an affordable price, a wide range of shades and stable resistance to temperature fluctuations. Among the minuses, one can note the susceptibility to deflection during transportation, the inability to dissipate ultraviolet radiation, and poor resistance to mechanical shocks.
Matte polyester is able to create a stylish and attractive appearance, it can maintain its original style for longer, and its price is considered moderate. However, it has a limited color range, and its coating is easily damaged by careless installation.
The semi-gloss coating is distinguished by giving the roof an expensive appearance, it is able to maintain a rich shade for a long time without losing its operational properties. The only disadvantage of such a design solution may be its overestimated cost.
The anti-rust coating for a metal roof will directly depend on the primer and its composition. It is customary to distinguish between the following types:
Naturally, over time, the coating will lose its useful properties under the influence of precipitation and sunlight. The more often these negative factors affect the roof, the more difficult it will be to maintain its qualities. At the same time, if the building is located near a chemical plant, a railway, a high-traffic highway, then the emissions from them will also affect the tiles. However, the presence of a high-quality protective primer will increase the service life of the material, but it should be understood that only Lux or Premium class products have such additives.
When choosing a metal tile for roofing, it is necessary to determine the following most important parameters:
Experienced builders-finishers recommend purchasing material with a margin of 10% of what is needed. However, if large-scale work is expected, then this figure can be increased to 15%. To calculate the amount of material relative to vertical rows, it is necessary to divide the width of the slope by the working width of the MCHP sheet, and then round the result upwards. This simple operation will allow you to lay the profiles exactly with an overlap.
To calculate the vertical row, you need to get an indicator of the total number of sheets. For this purpose, the length of the slope (from the skates to the eaves), the size of the total overhang from the eaves and the length of the overlap are added up. As a rule, the length of the overhang is 40-50 millimeters, which will depend on the thickness of the sheet and the stiffness of the profile. The characteristics of the overhang are very important, because it is the overhang that keeps the roof from the effects of precipitation, while protecting its internal structure from raindrops during gusts of wind. Also, the overhang provides additional security of the building at the junction of the roof and walls. Roofs with a slight slope should be covered with a large overlap in order to avoid increased operating load.
IMPORTANT! The examples of MCHP given in this rating can also be found at other prices than those indicated. The thing is that expensive models, most of which have special coatings, are sold at once in several sheets in a set and for them the estimated cost is NOT a square meter. Cheap samples are usually sold at a price per m2.
This model shows the special quality inherent in the Döcke brand. MChP production was carried out on the equipment of the best European manufacturer. In Germany, it passed a particularly strict production control before being sent to Russia. As a result: the material is produced using high-quality mixtures, where the control of the presence of PVC is an indispensable parameter. Performance characteristics using innovative technologies are subject to strict control at the stage of their production. The recommended cost is 320 rubles.
This sample combines rounded shapes, coupled with a deep relief. Regardless of the obvious position, improved locks perform the properties of tightness, which emphasizes some individuality of the structure. Using this variation, it is easy to obtain the norms of the "State Standard" of 2018 under the number 58153. The Monterey class coating used can give the roof some design zest, while providing reliable roof protection.The recommended cost for retail chains is 525 rubles.
This sample organically combines designer roundness, coupled with a deep relief, despite the fact that the basic component was presented at a high aggressive-chemical level. However, its horizontal joints may be less noticeable. If you emphasize the height of the steps from 35 millimeters, then the profile will receive a reliable and durable roof. At the same time, it will acquire an aesthetically sound context, which will additionally play, in view of providing additional reliability. The recommended cost for retail chains is 730 rubles.
This "velvet" corrugated board is an extremely sufficient option that presents itself as "silk", in fact it is not. In principle, it is possible to cover large areas with them, however, it will be necessary to take into account the imposition of snow, to which it is generally poorly adapted. In any case, he has a powerful protection in the form of body kits, which will try to prevent the occurrence of a general load. The recommended cost for retail chains is 650 rubles.
This profile is perfect for a standard gable roof. The coating is made of polyester, and the high wave pitch is able to successfully deal with sedimentary manifestations - rainwater and snow simply do not linger on the slopes. The model is considered universal and can be used in various climatic conditions, because it equally reflects sunlight and can accumulate it in sufficient quantities. The recommended retail price is 2400 rubles.
This profile has a structure that visually repeats the image of natural tiles. Graphite color is the main color, so it is preferable to install the product in cold latitudes in order to fully use the possibility of heat accumulation from the absorption of ultraviolet radiation. During installation, you should rely on accurate calculations, because it will not work to get a particularly wide overlap. The structure uses an innovative coating "Viking MP-E", which increases the anti-corrosion properties of the material. The recommended cost for retail chains is 2500 rubles.
This option can already be mounted on roofs with a complex slope. The ability to easily trim the sheet allows you to independently organize and the desired size of the overhang and properly protect the ridge. Trimming is done with any scissors for metal. The anti-corrosion coating is made according to the Norman MP formula itself and is intended for use in regions with inclement climates. The recommended cost for retail chains is 2600 rubles.
Another sample with a wide overlap, which is more suitable for gable and shed roofs. Its high price is due to the high-quality material of manufacture, the innovative anti-corrosion coating "Viking MP-e", and the wave, which is very convenient to mount. This item has a 10 year warranty from the manufacturer. The recommended cost for retail chains is 2700 rubles.
As a result, the analysis of the market was very complicated, which was due to the many samples, which in their diversity did not allow to identify priority areas. Nevertheless, based on the analysis, it is possible to single out only two structures - steel and aluminum, which are coated with complex compositions, and innovative ones, which include additional additives.Accordingly, the best roofing, even with irregular geometry, should be with soft tiles.
