Metal: how to put it. Technology of metal tiling

Light weight, easy installation and aesthetic appearance - this is an incomplete list of advantages of such a wonderful material, as metal. How to put it correctly, many owners of country houses would like to know, because this inexpensive variety of profiled sheet with original relief is very well deserved in our country. We'll talk about this later in the article.

Material specifications

First, let's figure out what, in fact, is a material such as metal. How to properly put it on the roof, we'll figure it out a little later. For the production of sheets of metal tiles, high-grade steel is used. Protection against corrosion is made of zinc, phosphate and polymer materials. On the back, sheets are covered with a special lacquer. Even before the protective layers are applied, the metal is stamped in such a way that characteristic waves form on it. Therefore from afar the building covered with such sheets looks like tiled.

What to look for when choosing

When choosing a metal, you need to pay attention to the following indicators:

• The thickness used to make steel. According to the regulations, to protect the roof should be used material is not thinner than 0.5 mm.
• The thickness of the zinc coating. This indicator should be at least 275 g / m ² . It is very good, if the sheets will be covered not simply with zinc, but with its alloy with aluminum.
• A variety of polymer coating. For the roofing of buildings built in the southern regions, it is worth using sheets with UV-resistant PVDX-coated sheets. In sharply continental climate, the material will last longer with a protective layer of pural, which is not afraid of temperature changes. Polyester and plastisol can be used almost everywhere.

What should be the color of the sheets

When choosing the color of the material, one should keep in mind that sheets of darker shades burn out faster than light ones. However, despite this, the most popular shades at the moment are dark red and cherry. Perhaps this information will be useful to somebody, but, of course, usually the choice is made taking into account the design features of the building itself. In any case, the house, covered with this variety of profiled sheet, will look stylish and aesthetic. All available in the modern market of metal tile differs juicy, nice-looking colors.

What should be the crate

Before we start to understand how to lay the metal, let's see how to arrange a crate for it. Since the material is sufficiently strong for bending, a solid base for it is not necessary. Of course, before installing the sheets, the roof needs to be waterproofed. Usually, polyethylene film is used for this purpose.

What is put under the metal tile yet? Instead of polyethylene, you can use a special membrane. This material will cost more, but there will be more sense from it. Modern waterproofing membranes are able to let steam from inside (from the "pie") and not let the water from outside - from the side of the street. Of course, this will help preserve the internal structure of the roof. Mount waterproofing with a small sag, otherwise the rafter system, with shrinkage and strong wind, will move, and it will just break.

Some owners of country houses are interested in the question of whether it is possible to put metal roofing on the roofing material or not. The use of this material is also permitted. However, in this case it is important not to let sheets contact him. Otherwise, the metal tile will quickly rust. Both films and roofing felt are best attached to the rafters with bars. To them and in the future will be stuffed lath. Thus, a small ventilation layer will be obtained, which will prolong the service life of the roof.

The material of the crate itself does not have any special requirements. The metal tile is lightweight and the truss system does not overload. The only thing you need to take care of when deciding how to put a lath under a metal tile is that the step between the battens is equal to the width of the sheet. Otherwise, fixing the material will be difficult. Fix the crate necessarily galvanized nails.

Calculation of metal

Before we begin to understand how to put metal roofing on the roof, let's see how this material is calculated. Find out the number of sheets needed to cover is not so difficult. On the gable roof, first calculate the area of the skates. Then divide the result by the area of the sheet. At the moment manufacturers are producing metal tiles of various sizes. The length of the sheet can vary from 0.5 to 6 m. Most often on sale you can find material in 4.5 m. Such sheets are more convenient in stacking, and therefore are sold better. The width of the material varies from 1.16 to 1.19 m. If the purchased sheets are smaller than the slope, horizontal overlap must be taken into account when calculating. Usually its width is 15 cm.

For four-pitch roofs, the calculations are, of course, more difficult. In this case, it is necessary to use the formula for calculating the area of a triangle - S = 1 c × h, where c is the length of the base, and h is the length of the height drawn to it.

What you need to buy for a roofing device

Now you know how to choose and calculate such material as metal tile. How to put it correctly is a question that depends, among other things, on how and how to cut out sheets and fasten them to the crate. Before installation, it is necessary to prepare:

• Shears for metal. It is impossible to cut this roofing material with a bulgarian, as the polymer layer is burnt out.
• Roulette and square.
• Self-tapping roofing with wide washers.
• Stairs.
• Soft shoes. It is necessary to walk as carefully as possible during the installation. If the polymer coating is damaged , the material will not last long.

Mounting the gutter

Gutter system should be arranged under the roof of any material. Including and such, as a metal tile. How to put the sheets on top of the gutter? They will need to be placed in such a way that water gets to this receiver. The sheets are fixed over the cornice bar, covering the holders of the gutter. The latter nail to the bottom board skateboards skates. The step between them depends on the type of drainage system.

Layout of sheets

Next is mounted, in fact, the metal itself. How correctly to put this material? In fact, this is not difficult. The work is carried out in several stages:

• First mount the cornice. It can simply be nailed with galvanized nails. The overlap between the elements should be 10 cm. The nails are nailed in 30 cm steps.
• Then metal tile is mounted. How to put the first sheet of material? This question is really very important. After all, all the other elements will be aligned on it. The lining of the roof begins from the butt. The first sheet is lifted to the roof and carefully leveled along the cornice with a ledge for 4-5 cm. Then it is fixed with a screwdriver at the ridge.
• Pick up the second sheet, level it and attach it to the first wave along the crest of the wave at the top and bottom with two screws.
• This way you can hold up to four sheets.
• Next, the group is carefully leveled over the cornice and fixed to the crate completely. Fixation is made by screws in the interval between the waves, through one.
• In places of overlapping sheets fasten in a crest of a wave (also through one).

Thus they cover the whole roof. At the last stage, fix the end plates.

Mounting of

How to put metal roofing on the roof, we found out. Next, consider the installation technology of various additional elements. Modern cottages often have an original design, and their roofs - a complex design. Sewing the roof of such a building, most likely, will have to mount valleys. Usually they come complete with the metal. Even before installing the sheets at each skate joint it will be necessary to fasten the bottom bar of the metal valley. The overlap between the elements in this case should be of the order of 15-20 cm. The bracket is fixed to the screws with a step of 20 cm. After the roofing of the roofing with metal, the upper decorative edge of the valley is set at the junction.

Mounting the pipe "apron"

The question of how to properly lay the metal tile comes down to how to trim the chimney. In order to mount the "apron", you need to continue in its walls strobes depth of 15 mm. "Aprons", as well as valleys, are usually delivered complete with sheets. A heat-resistant waterproofing (5 cm) should be removed to the pipe. An additional crate is packed around the chimney. After the installation of sheets of metal tiles, the "apron" itself is attached. The upper strips should be pressed against the pipe and wound in the strobes, previously smeared with the last sealant. Attached is the "apron" to the installed additional crate through the metal tile. At the last stage, all four parts of the apron are joined together by self-tapping screws.

Mounting of the ridge and ventilation elements

The roof for the roof of metal can have a triangular or semicircular shape. In the latter case, special stubs are provided at its ends. Mount the skate on the seal with screws through the wave. The overlap between the elements should be 10 cm.

Ventilation holes should be drilled before the sheets are installed. After the roof has been sheathed, their edges are treated with a sealant and inserted into them ventilation elements. Mounting is performed on the self-tapping screw.

Installation of snow chains

How to properly lay the metal and additional elements, we hope you now understand. Sheathing is qualitative, but, unfortunately, very slippery. Therefore, in the winter from the roof covered with it, real avalanches can descend. In order for this not to happen, it is necessary to install more and snegozaderzhateli. They are mounted in 35 centimeters from the roof cornices. The distance between the mounting brackets is about one meter. At the edges, the brackets are fixed at a distance of half a meter from the ends of the snow holders. In the event that the roof slope is longer than 8 mm, additional intermediate elements are additionally installed. Without fail, snegozaderzhateli must be mounted above the attic windows.

Skylights

Under the roof of modern country houses is usually arranged attic. Of course, this room should be well lit. The area of windows is calculated taking into account the area of the attic, as 1 to 10. That is, in an attic of 30 m ² it will be necessary to arrange windows with a total area of 3 m ² .

Most often, the frames are installed at a height of about a meter from the ceiling. The easiest way is to buy ready-made windows and mount them according to the manufacturer's instructions. Frames are fastened simultaneously to the crate and rafters. The openings under the window are cut in metal tiles with metal scissors. Carrying out this work, it is necessary to take into account that they should be 6 cm more than the window frames horizontally and 4 vertically. This space is subsequently filled with a heater.

Roof insulation from metal roofing

So, the roof is made of such wonderful material as metal roofing. How to put the sheets, you now know. However, in order to arrange a full attic, the roof should be insulated. The easiest way is to perform this operation from the inside - from the side of the attic. Insulate the roof in this case in several stages:

• Rafters are treated with antifungal and fire-resistant agents.
• Between them are installed insulation plates. Usually it is mineral wool or styrofoam. The insulator is fixed with a wire.
• Next, the rafters are filled with a vapor barrier.
• The bars are fixed finishing. It can be plywood, boards, boards, plasterboard, etc.

Well, we hope, we answered the main question of the article - how to properly lay the metal tile. Observing all the put technologies, it is possible to arrange a beautiful, durable and, most importantly, reliable roof.
