Metal roof coating technology

Metal tile - material is relatively new, but firmly conquered authority from the consumer. Due to its numerous properties, ranging from aesthetic appearance and ending with reliability and quality, more often builders and their customers choose the roof covering precisely metal tile.

To perform the roof cover with metal tile with your own hands - the task is quite difficult if you do not have construction experience. However, experts argue that when studying detailed instructions and the availability of sensible assistants, especially if the roof that needs to cover the usual shape, then there is nothing impossible.

The main advantages of metal tile

Along with the widest spectrum of roofing materials, metal tile today is in great demand. This is due to the range of its advantages:

• excellent resistance to different temperatures, as well as to its drops;
• the durability of use is the bright colors of the metal tile actually over the years they do not fade in the sun, and your home will be like a new one and after many years;
• strength is the indisputable quality of metal tile. Production will be improved over 30 years of its existence on the market, today it is the most complicated process of coating a profiled sheet of galvanized steel specially developed polymers and varnish;
• the cost of covering the roof with metal tile is quite loyal, which also speaks in favor of the choice of this particular material;
• the roofs covered with metal tiles look aesthetic, rich and beautiful.

Delivery and storage of material

Selecting the profiled sheets in the store, there are several questions with their delivery to the construction site. Here are some important tips to consider:

• direct loading and unloading of the material should be carried out exclusively by the mechanized method. Only in this case, the manufacturer retains its warranty obligations;
• if you acquire a lot of material and do not plan to start the installation for quite a long time, then the sheets need to be unpaved and put on each other, be sure to separate wooden planks
• watch the workers tolerate sheets, keeping them at the top along the sheet. The transfer of sheets should be carried out at the rate of 1 person per 1.5 materail. In no case can not allow the sheets when carrying bent.

Technology roofing work

The coating technology of the roof of metal tile implies several rather difficult stages:

• installing the roof pie;
• trimming and preparing profiled sheets for installation;
• laying and fixation with screws of metal tiles to the crate.

Installation of roofing pie

It is important to take into account that the technology of covering the roof of metal tile, primarily requires the preparation of the roof pie. The cake is called the design of several layers, each of which has its own purpose. The design of the cake is different depending on whether the construction of a warm or cold roof is planned.

Cold roof is most often selected for non-residential premises and includes:

• layer of waterproofing film;
• counterclaim;
• clamp;
• primary crate;
• rafter.

Warm roof involves a more complex design of roofing pie, which is why the roof coating with metal tile will increase its price somewhat, but the money factor here plays a smaller role, since the roof over his head is done for many years. In the roofing pie of a warm roof enters:

• one-sided vaporizolation, which will produce wet air, but do not inlets;
• the rapid system that will carry the main carrying function for the roof. It includes both rafters and longitudinal runs;
• inside the rafter system is a layer of thermal insulation materials;
• among the thermal insulation will certainly need to leave the ventilation gap;
• the counterclate performs several functions at once: enshrines waterproofing and is a fastening for the crate;
• the lamp, which later fastens the metal tile leaf itself. The material for the crate can be the wooden bars treated with a special antiseptic, as well as perforated galvanized steel profile. The lamp is fixed with a certain step, which usually does not exceed 45 cm;
• metal tile.

Cutting and installation of sheet metal tiles

The cutting of sheets of metal tiles is the initial stage of its installation. Almost always, it has to be performed on Earth, after which he already raising the roof. In general, experts recommend as less as possible to resort to its cutting, but if it still arises such a need, you should always remember several rules:

• individual protection products in the form of glasses and gloves should always be with you, do not neglect them;
• the cutting of sheets of metal tiles involves the absence of using any abrasive tools, it will damage the protective coating layer. Use the electrolovka or the disk saw;
• sections of sections should also be protected. For this, be sure to purchase a special paint and cover it unprotected sheet layer.

Turning directly to the installation, first of all, remember that cut plots should be attached to whole - it will keep the durability of the coating.

Fixation of sheet metal tiles

For fasteners, metal tiles are used special self-tapping screws, the size of which is 4.8x28 mm. Self-tapping screws should be covered with a special protective coating under the color of the metal tile. The average consumption of self-mains on the roof is correct forms is up to 10 pcs. 1 M. ².

1. For more dense fixation, it is important to use the washers to seal the screws.
2. Before starting fixation, the metal tile sheet must be drilled in the locations of the screws. It is not recommended to screw them off on their own, because it is so possible to damage the protective layer, which is covered with a sheet.
3. An important point should be that the self-timing is attached exclusively perpendicular to the crate, any slope is unacceptable.
4. Fixing the screws, count the strength: it should not be too tightly attached to the metal tile to the crate, the roof should be as if slightly pressed. But it is impossible to leave too weak fixation.
5. Additional fixation by self-draws requires the place where there are overlaps - this will increase the roof reliability.
6. Starting the roof, first align the ends relative to the eaves, after which you just need to be attached to fixation.

Depending on which form of a crumbling roof, there are several main technologies for the start of the roof cover with metal tile:

• when the bartal roof is roof, you can start from the end, from the right or left - it does not matter;
• if the sheets began to lay on the right, the region should be superimposed on the previous one, and if on the left, then under the previous sheet;
• if the roof is column, then the sheets of metal tiles need to be stacked from top to bottom and as they start switching to the sides.

After completing the laying on the roof rods, you need to start the installation of the final elements. The lip of the roof is decorated with a ski bar, it is necessary to fix all the skate elements of the metal tile. Button strips are attached to all places where the tiles leaves are adjacent to the vertical surface.

How much does it cost to cover the roof?

Of course, this question remains the most popular, because starting to cover the roof with a metal tile, it is important to know full rates. They will depend on several factors:

• roof view: Cold roof will be the cheapest option; Warm requires the complex design of the roof pie;
• who performs the work: making all the work on their own, you can save money. But if you do not stick to a certain technology, then you risk reduce your roof life many times. Getting started to the roof of the roof yourself, you need to carefully examine all the instructions, the opinions of specialists and view the training videos on the topic "Cover the roof of metal tile";
• having hired a brigade of builders, make sure of its competence, because if the work is done poorly, after a few years it will have to start working again, which will double, and may also triple the cost of overlapping.
