Metal tile is by far the most popular roofing material among summer residents and owners of country houses. Its main advantages are low cost, long service life and attractive appearance. The sizes of metal tiles for roofing are standard, which makes it easy to calculate the number of sheets required for roofing of any configuration and area.

General Description

Metal tiles have excellent performance due to their unusual structure. It is made of sheet steel with a thickness of 0.4-0.6 mm by cold stamping. From above, each sheet is first covered with a zinc layer, which provides reliable protection against water and, consequently, against rusting of the metal. Next, a passivation layer is applied, and then a primer layer. At the final stage, the sheets are coated with a special polymer composition that has a color and texture. This layer not only protects the metal from adverse climatic and mechanical influences, but also gives the roof an aesthetic appeal and expressiveness. Your nameThe metal tile was received not by chance. From a distance, roofing sheets of this variety actually resemble expensive clay tiles.

Width

The dimensions of the metal tile for the roof in the marking must be indicated. The amount of material required for sheathing is chosen, focusing primarily on the width of the sheets. At the same time, attention is paid not to the general, but to the useful. The latter is always smaller than the former, since the metal tile is laid on the roof sheathing with an overlap.

The total width of a metal tile sheet can be 1.16-1.19 m. The overlaps are usually 0.06-0.08 m long. The useful width of metal tile sheets is usually 1.1 m. However, sheets of 100 cm, 105, 118, etc. can be found.

Length

The dimensions of the metal roofing for this indicator can vary greatly. On sale there are sheets from 80 to 800 cm long. Therefore, if you wish, you can easily choose a material that is ideal for absolutely any roof. The length of a metal tile is always a multiple of 5.

When buying sheets for the roof, it should be borne in mind that the size of the overhang of the metal roof should not exceed 40 mm. Otherwise, the metal may subsequently bend or wrinkle. If the length of the slopes exceeds 7.5 m, the metal tile should be laid in two rows. The slope angle for this roofing material should not be less than 14 degrees.

Metal tile thickness

Thus, what are the standard sizes of metal roofing tiles, we found out. Now let's see what the thickness of this material can be. As already mentioned, steel 0.4-0.6 mm can be used for the manufacture of metal tiles. Also, the thickness of the material depends on the thickness of the polymer layer deposited on it. This indicator is usually 25-50 microns. Thus, the thickness of the sheets of metal tiles can vary within fairly wide limits. The greatest demand among owners of country houses is 0.5 or 0.45 mm material.

Types of polymer coatings

Decorative protective layer of metal tiles, thus, can have different thicknesses. The following types of polymer coating can be applied to sheets:

  • Pural. This polymer is considered an excellent corrosion protection and can withstand temperatures from -15 to +200 degrees. Of all types of polymer coatings, this is the thickest - 50 microns.

  • Polyester. For people with average incomes, this is the most suitable metal tile (roof). The price per sheet (the dimensions of this type of material may be different), covered with such a layer, is the lowest. However, its thickness is less than sheets covered with pural - 25 microns. Metal tiles with such a protective layer can be mounted on the roofs of houses built in regions with a normal climate without extreme temperatures. Today on sale you can find such sheets of a slightly different variety - coated with polyester in combination with Teflon. This type of polymer layeris more resistant to various kinds of mechanical damage. The thickness of the Teflon-polyester coating is 35 microns.
  • Polydifluoride. This is the most expensive type of polymer coating. Its advantages primarily include high resistance to fading. Therefore, sheets with such protection are most suitable for sheathing the roofs of houses in the southern hot regions. The advantage of polydifluoride is resistance to mechanical damage and a very long service life. The thickness of the PVDF layer is 27 microns.

  • Plastizol. Sheets of metal tiles with a coating of this type are quite rare on sale. The fact is that the polyvinyl chloride used to make plastisol is considered environmentally not very safe. The metal tile of this type enjoys a certain popularity only due to the fact that this polymer is characterized by increased strength and lasts a very long time. Plastisol thickness is 200 microns.

The cost of a metal tile, depending on the type of coating, can vary between 150-250 rubles. per square meter (for 2015).

Profile height

Roofing metal tiles, the standard dimensions of which are very convenient, can also vary in wave height. The value of this indicator depends primarily on the geometry of the profile, which can be different. The most popular metal tile waveforms are:

  • Monterrey. This is the most common variety. This type of profile imitates claytiles. The wave height of such sheets is usually 39 mm. Supermonterrey sheets are also on sale. This material has a slightly higher wave - 46 mm.
  • Cascade. This type of metal tile is somewhat reminiscent of a chocolate bar. The height of its profile is 25 mm. This is a very beautiful variety, but at the same time quite expensive. Brown cascade sheets look especially impressive.
  • Dune. The advantages of this variety primarily include the possibility of using hidden fasteners. On the roof, this material looks very solid and, compared to other types, quite original. For a metal tile of this variety, the wave height indicator is 46.5 mm.

Metal tiles for complex roofs

To a broken roof today you can order a complete set of sheets with accessories. To do this, call an employee from a company specializing in the supply of this material. A professional will inspect the roof with the order. This will take into account such parameters as the complexity of the configuration, the features of the truss system and the size of the roof. A metal tile (and accessories for it, if you call a specialist, you won’t have to look for it - which is very convenient) - the roof is very simple to install. However, installing it on broken roofs of an unusual configuration for people without experience can still cause certain difficulties. Companies specializing in the supply of metal tiles usually provide services for its installation. Therefore, in this case,think about paying for the installation of sheets.

How to cut

Manufacturers select the dimensions of metal roofing tiles in such a way that it is as convenient as possible to install. In cutting when installing on the roof, this material practically does not need. However, sometimes you still have to cut it. Before performing this operation, you need to decide on the choice of tool. The fact is that the upper polymer layer of the sheets is very easily damaged. Therefore, for example, it is impossible to cut them with a grinder in any case. This tool heats up the workpiece too much. In addition, sparks fly from under the circle when cutting metal, also damaging the polymer layer. Metal tiles are usually cut with electric shears. You can also use a jigsaw or a drill with a cricket attachment.

Rules for cutting

To cut the material, therefore, should be correct, whatever the size of the metal tile. For roofing (the price of this material depends primarily on its length), sheets of complex configuration sometimes have to be cut both in length and in width. In the second case, when cutting, among other things, you should pay attention to the direction of the profile. Each sheet of metal tile has a top and bottom. Do not turn over the material during installation.

The length of the metal tile can not be cut at every point. So, for example, the cut line in no case should pass through the region of the wave drop. If the cutting is done incorrectly, the sheet in the future simply cannot be installed on the roof, as it will be deformed.

The dimensions of standard metal tiles (length, thickness, width) are convenient for laying on any type of roofing. It is this, combined with the cheapness and relative ease of cutting, that makes the material so popular. It is not difficult to choose the most suitable metal tile in a particular case. In extreme cases, it will be possible to contact specialists who will make accurate measurements.
