To protect the roof today can be useda variety of materials. One of the most popular, of course, is metal (profiled). It is made by cold rolled steel of high grades. You can do it yourself with your own hands, because one of the undoubted advantages of this material is ease of installation. The professional flooring can be used for roofs of any sizes and configurations. Today, these roofs can be seen everywhere.
What is a professional flooring
Professional sheet is a plate of prettythin metal (from 0.5 to 1 mm), covered with a polymer layer. Its surface is made in the form of waves. The size of the metal profile for the roof can be very different. When choosing a type of material, first of all it is necessary to pay attention to the height of the wave and the thickness of the metal used to make it.
Main advantages of a professional flooring
The main advantages of the metal profile, in addition to the ease of installation of sheets, include:
- light weight (from 3 to 20 kg);
- fire resistance;
- ecological purity (metal profile is completely safe for human health);
- durability (sheets of this material are not at all afraid of exposure to ultraviolet radiation, temperature changes, acid rain, etc.);
- low cost (profiled - one of the most inexpensive materials to date);
- aesthetic appeal;
- high degree of strength;
- reusability.
The disadvantages of the metal profile
The disadvantages of this material should be attributed beforetotal noise However, when using a sufficiently thick insulation layer, which in this case can also be considered as noise insulation, the consequences of such a drawback can be reduced to almost zero.
If the outer decorative layer is damaged onsheets may develop corrosion. Some disadvantage can be considered the fact that, arranging the roof of the metal, you need to very carefully ensure that the joints between the elements were sealed as much as possible. Otherwise, the finished roof will leak.
Varieties of material
If we talk about the scope, there are three types of metal profiles:
- Material brand "C". Used for finishing walls.
- Professional sheet mark "H". It has the highest strength characteristics and can be used for roofing.
- Material brand "NS". It can be used for fencing, wall cladding, and roof protection.
Собственно профнастил – это самая дешевая type of metal profile. Besides it, there is also metal tile - a very aesthetic and practical material. Roofs covered with it look just great. Thus, the professional flooring and metal tile are the main types of metal profiles for the roof.
The main stages of work with the device of this type of roof
Installation of the roof of the metal profile is carried out in several stages:
- device truss system;
- installation of vapor barrier;
- installation of heat-insulating material, at the same time mineral wool is most often used;
- installation of a waterproofing layer;
- device crates;
- installation of drainage system;
- installation of sheets of metal profiles;
- lining rafters from the attic.
In this case, steam, hydraulic and thermal insulation is arranged in the same way as for any other roofing material. The crate is packed taking into account the size of the sheet metal.
Installation of drainage system
Before starting installation of the roof frommetal profile, it is desirable to arrange a drainage system. At the first stage, the holders of the gutter are fixed to the crate. The edge of the latter should ultimately be located about 3 cm below the edge of the future roof. Otherwise deformations are possible at a snowfall in the winter. After the holders are installed, the gutter is inserted into them. Next to the crate attached eaves. Its installation is carried out so that the edge of the gutter is blocked. Also on top of the ledge strip will need to bring the edge of the waterproofing film.
Calculation of the roof of the metal profile
Do-it-yourself metal roofing will be arranged with savings if necessary calculations are made. In this regard, first of all takes into account:
- The number of elements in the horizontal row.To do this, pre-measure the length of the roof slope. Of course, respectively in the horizontal direction. The resulting figure is divided by the width of the sheet. The length of the overlap between the elements is also taken into account.
- To calculate the length of sheets and the number of rows, you need to add the length of the overlap and the length of the overhang of the cornice to the length of the slope (vertically).
In order to find out how many self-tapping screws are needed, it is necessary to calculate the area of the future roof and multiply the resulting figure by 6.
Preparation of tools and materials
Before proceeding with the installation of the roof, it is necessary to prepare the tools. At hand should be:
- building level and plummet;
- scissors for metal or jigsaw, necessary for cutting sheets;
- electric drill;
- pencil and gon;
- screwdriver;
- self-tapping screws.
The sheeting itself must be transported and lifted onto the roof with the utmost care. Otherwise it is possible to damage the protective polymer layer.
Installation of sheets on the slopes
Now let's see how the work itself is arranged.a roof from a metalprofile the hands. Installation of sheets start from the bottom. They are fastened to the crate with screws in the lower part of the wave. This will ensure reliable installation. Overlap should be performed for at least one wave. On one 1m2 roof should have at least 6-7 screws. The horizontal overlap (between rows) should be about 20 cm.
Facing gable
In the production of the calculation required forThe facing of the pediment of the material takes into account exactly how it will be laid. The most economical is considered a horizontal method of installation. In addition, in this case the house will look more aesthetic. When calculating it is worth considering that the trimming takes about 10-15% of the material.
Для фронтона вполне подойдет стеновой профнастил brand "C". You can also use the material "H" and "NA". After performing the heat and waterproofing mount the frame of wooden slats. They will first need to fix the windproof film. Professional sheet is cut using a hacksaw or jigsaw.
Arranging the roof of the metal, you need to beextremely careful in terms of the possibility of damage to the polymer coating. Otherwise, the service life of the structure will be significantly reduced, as the elements will start to rust over time. Therefore, it is not recommended to use the grinder for cutting sheets. To fix the cut professional sheet to the frame should start from the bottom corner. All elements are mounted overlap.
Skate mounting
The roofing of the metal profile includesyourself also install the skate. The corner of the slopes at the top is closed with a ready-made element, which can be purchased simultaneously with the purchase of sheets. The horse is made of the same material as the main elements. It is necessary to prevent water from getting under the sheets. Laying in this case should begin to perform with the opposite direction prevailing in this particular area of the winds side. Ridge elements are mounted with an overlap of 15–20 cm in a ridge with a pitch of 20–30 cm. Self-tapping screws are also used for fastening.
In the event that the slope of the roofsmall, under the ridge elements should put a special seal, which can also be purchased at the hardware store. Between him and the ridge should remain a small ventilation gap.
Installation endovy
Mounting the roof of the metal profile is necessaryamong other things, properly install endovy. In this case, good sealing is very important. Endovo is called the chute, which is included in the internal inclined intersections of the slope. It is mounted on a continuous crate, arranged on both sides.
На настоящий момент представляется более чем appropriate use to protect the roof of such a modern material, as metal profiles. Installation of the roof in this case can be carried out in a short time and without the involvement of professionals. For a little money, the owners of the house will receive a reliable protection of its internal space against all adverse environmental factors.
