The market for roofing materials is diverse, potential buyers can choose low-cost "euro-slate", metal, bitumen or ceramic tiles, folding roof of copper and titanium, natural slate. The cost of these materials ranges from 2-3 cu for the "euroslate" to 200-250 euros for the exclusive varieties of natural slate. Each proposal has its own advantages, but the composite tile has absorbed all the best aspects of all roofing materials. Developed and established the release of this product in the middle of the twentieth century in New Zealand, it appeared on the domestic market 10-15 years ago and caused controversy among professionals. Today, composite tile occupies a worthy place in the assortment of leading companies, successfully competing with metal tiles and soft tiles.
What is composite tile?
The roofs of houses should be beautiful, reliable, durable and affordable. This is what most real estate owners around the world think. The most popular roofing materials are metal and shingles. The first one is valued for its affordable cost, simple installation, durability, but at the same time it is criticized for its monochrome color and poor snow retention, increased noise level during rain. The flexible tile is deprived of all these lacks, but has higher cost and differs in increased exactingness to the basis. As a result, roofers lay expensive waterproof plywood under it and use lining carpet, the cost of which is close to the price of tile. As a result, the cost of the roof increases by 2.5-3 times, compared with the roof of metal.
Combine all the advantages in one material could composite tile, which has the following original structure:
- steel sheet 0.4-0.5 mm;
- Aluzinc anti-corrosion layer;
- acrylic primer;
- acrylic resin based decorative layer;
- basalt granulate to protect against mechanical damage and reduce noise;
- a layer of acrylic glaze.
Bottom sheet is protected by a primer and alyumotsinkovy anti-corrosion layer. Such a composite tile device ensures long life and excellent technical characteristics.
An important feature of the material is its modular design. Unlike metal tile, which is produced by sheets of different lengths up to 8 m, composite tile is produced in short sheets 40-45 cm long. This gives it a number of technical advantages over cheaper metal tile.
Advantages and disadvantages of composite tile
Like any material, composite tile has its pros and cons, but manufacturers do not hide the disadvantages from customers. In fact, it is one - a rather high cost, but it must be borne in mind that for the installation of roofing material does not require such costs, as is the case with flexible tiles. Another disadvantage for a long time was a strong surface roughness, for this reason dust accumulated on it, and there was practically no chance to get rid of dry leaves and needles on the roof. Manufacturers have recently found a way out - they began to pour basalt granulate with a layer of transparent acrylic resin. Due to this, the roughness became more streamlined and the dust became easy to wash off with rain water.
All the cons of composite tile can not compete with the advantages of this material. Among its main advantages:
- high speed of installation;
- impeccable appearance;
- good snow retention;
- wide range of operating temperatures;
- a wide range of shades and shapes;
- long service life;
- minimum waste;
- easy installation;
- low weight
Houses made of composite tile look no less expressive than the mansions, covered with ceramic tiles.
An important advantage of the material is the compact size of the sheet, it greatly simplifies transportation. Where a metal truck requires a truck with a body length of at least 4 m, a pickup truck is sufficient to transport composite tile. Compact pallets with roofing materials are easier to store, and for feeding sheets to the roof there is no need to involve special equipment.
Calculation and laying of composite tile
To make an exact calculation of composite shingles allow special programs that take into account the specificity of the profile, overlap, the shape of the individual slopes of the roof. It is always better to use a similar opportunity when estimating. However, the need to pre-calculate the cost of roofing materials yourself at the planning stage of the house arises for all customers. To do this, it is necessary to calculate the area of all roof slopes, then determine the useful area of the composite sheet. It will be 10-20% less than the total area of the tile sheet. After that, it is necessary to divide the area of the roof into the useful area of the composite and add 5-10% to the resulting number. The result will be the number of sheets that will be required for roofing work.
Installation of composite tile on the batten, similar to that used for metal tiles.
The only difference in its formation is the step, which should be equal to the wavelength. So, for metal tiles, the most popular steps are 350 and 400 mm, and the laying of composite tile is made in 370 mm increments. The upper row of tiles does not have a fixed size, the crate is laid with a wave step from bottom to top. To determine the length of the top sheet, measure the distance from the batten to the ridge and trim the sheets to the desired size.
Mounting from top to bottom and against the prevailing wind direction. At first the top row is formed, then the second row is mounted under it. Composite tile is fastened with nails in the end of the wave at an angle of 45 degrees to the crate. At the same time two sheets are pushed at once - upper and lower, thus, they are securely fixed to each other. It is recommended to use special fasteners with hats of tile color and with a protective acrylic coating. In this case, the nails will not stand out on the roof.
Installation of composite tile on the pediment has a certain specificity. Manufacturers of roofing material recommend bending the edge of the sheet at an angle of 90 degrees upwards at a distance of 40 mm from the edge. On the formed bend, a seal is glued to which the wind board is pressed. After that, an end strip is laid on the formed structure and nailed with roofing nails.
The main manufacturers of composite tiles
This roofing material is not released in every city as a metal tile. Production technology has its own difficulties, requires the use of specialized equipment. Among the most popular brands:
- Metrotile is a Belgian company offering 10 tile collections with different waveforms;

- Tilcor is a New Zealand brand under which roofing material is produced of 7 different types of profiles and 40 colors;
- Decra - the Belgian company Ikopal under this brand produces composite tiles in the Mediterranean and classical style;
- Luxard is a brand of the Russian company Technonicol, whose products are of high quality and affordable price.
The roof of composite tiles has a great appearance and excellent technical characteristics. A wide choice of profiles of different shapes allows you to choose materials for buildings in the classical, modern, Mediterranean or American style. The range of products that can be combined with log walls and exquisite decorative plaster. All this allows you to recruit composite tiles growing popularity around the world.
