The technology of installing roofing from corrugated board again became of interest to private developers and professional builders after the material acquired a new technological coating based on polymers. This allowed the creation of roofing systems that are invulnerable to external aggressive phenomena. In addition, corrugated board with a single or double-sided coating of polyester or plastisol began to look presentable. Among the positive characteristics of this material can be distinguished long service life, high strength and low weight, the latter of which allows you to work on the arrangement of the roof without involving heavy equipment.
If you are interested in the technology of the device of the roof from corrugated board and you do not have the appropriate skills in conducting this kind of work, then you can use the instructions that are attached to the material. This will greatly simplify the process. By purchasing corrugated board, which is produced under the labeling 35 or 44, you can perform installation of a gable roof system. With a single-pitched system, which, as a rule, is installed in baths, garages, pantries or sheds, the situation is simpler.
Material selection
The technology of roofing from corrugated board suggests the need for the right choice of material. Initially, it is necessary to determine the length of the ramp. It is by the distance from the ridge to the cornice that the roofing sheet is calculated . It should be noted that the profiled canvas, which is sold in rolls, can have a length of 12 meters. The corrugation height guarantees strength characteristics and is described in the marking. So, if you purchase material labeled HC35, then the canvas will have a wave height of 35 mm, while the canvas labeled HC44 has the mentioned parameter of 44 mm.
The technology of the device of the roof from corrugated board provides for the determination of the load on the roof system, this indicator will depend on the angle of inclination of the slope: the larger it is, the greater the load will be. With a more impressive tilt angle, the thickness of the sheet of roofing material increases.
Selection of additional parts
Roofing from corrugated board, the installation instructions of which must be known to the master before starting work, requires the use of fasteners. As it is used self-tapping screws, the size of which is 4.8 x 35 mm. The fasteners should be with a washer, which is made of neoprene rubber. Whereas for the arrangement and fastening of the ridge elements, fasteners should be used, the size of which is 80 mm or more. At this stage, rivets will also be needed, but you must choose those that match the shade of the coating. By purchasing a profiled flooring, you will receive additional structural elements in the kit, among which are:
- end plate;
- parapet;
- wind bar ;
- horse;
- endow;
- cornice strip.
In order to carry out work according to the rules, it is necessary to include a heat and water insulator in the roofing system, the last of which must be represented by a membrane variety. A traditional ruberoid is also suitable for this. But in order to get rid of small cracks and cracks, it is necessary to use mastic.
Positive features of a profiled sheet
Roofing from corrugated board, the installation instructions of which provide for the use of many materials, will ultimately have a lot of positive characteristics. Among them, we can highlight the suitability for mounting any angle of inclination, as well as profitability. In addition, the coating will turn out to be really high-quality, and the work will be possible to produce in the shortest possible time. The process will not be accompanied by special difficulties, and during operation, the coating will be easily repairable. If necessary, the profiled flooring can easily be removed, and then installed in its place. Before the start of the process, the profiled sheet is convenient to transport and store.
Technology implies the need for sheet cutting. This process is not difficult, with regard, incidentally, and drilling.
Material quantity calculation
In order to produce the work that is described in the article, you must first know how much material to be acquired. For this, a roofing calculator from corrugated board is useful, however, such calculations can be done independently. For this, it is important to initially determine the area of the roof to be covered. To do this, the length should be multiplied by the width. After the same way, the area of one sheet of corrugated board is determined. Then the first indicator should be divided into the second. This will allow you to get the number of sheets that need to be purchased.
However, when carrying out calculations it is important to take into account that the installation is carried out with some overlap of sheets, in addition, the allowance should be 5 cm. That is why about 15% must be added to the numbers that were obtained during the calculation. It is important to purchase the required amount of fasteners. It can be calculated, given that one meter square will take about 8 units of fasteners.
Installation of the crate
When arranging, focus on the SNIP. Roofing from corrugated board will turn out to be durable, if you follow these rules. According to them, it is necessary to begin arrangement work with the installation of the crate. It is on it that roofing material will be attached. Previously, the vapor barrier film has to be strengthened on the rafter base, while it is important that the material be strengthened with some sagging, which is approximately equal to 20 mm.
It is necessary to start work on fixing the film from the cornice, it should be covered with an overlap, the width of which is approximately 15 cm. But the fastening of the paintings is done using nails that are driven into the rafters. Whereas the joints should be eliminated by using tape. This will eliminate the occurrence of condensate during temperature changes.
In the process of work, it is necessary to take into account the SNIP. The roof from the corrugated board in this case will be equipped according to the technology. Among the requirements, one can single out the need for processing the crate with an antiseptic. This also applies to the rafters. The elements of the crate must be mounted in the longitudinal direction. The bottom located board will be strengthened along the cornice, it should have a more impressive thickness.
If you install the crate correctly, then you will have a strong roof, galvanized corrugated board will be attached to the frame elements, which are represented by bars with a cross section of 5x5 cm. This is true for a single-pitched system, the angle of which is less than 15 about . It is necessary to install the bars at a distance of 25 cm. Whereas with a more impressive slope, the crate should be solid.
Roof mounting
The cost of roofing with corrugated board will depend on the complexity of the work and the area of the roof. As a rule, the price varies within 700 rubles per 1 m 2 . It is necessary to start work in dry, calm weather. You can lift the sheets using ropes. It is necessary to start fastening the sheets from the bottom row and the pediment, which is true if the size of the canvas provides for overlapping. It is necessary to form an overhang from the eaves, which is 30 cm, and a gable equivalent of 7 cm. If the canvas does not cover the entire roof, then it is permissible to use several sheets.
Decking, the dimensions of which can be different, is attached from the bottom and sides, into the hollows. The vertical overlap should be equal to 20 cm. The resulting lumen is sealed with sealant. You can choose a sheet with a width of 800-1200 mm when buying.
Installation of additional elements
As for the additional elements, they are used for different purposes. For example, such additional elements for corrugated roofing, like end strips, are used to protect against wind. Their installation begins from the eaves, and they should be led out to the ridge of the roof. It is necessary to do this after the slopes are completely covered, while it is necessary to increase about 5-10 cm. They are fixed to the end of the pediment and to the roof, the distance between the fasteners should be 1 meter.
Setting the skate bars
There are also additional elements for roofing from corrugated board, which are called the levels of the ridge. Their installation is carried out with an overlap, which is equal to 20 cm, but not more. Use with this additional seal. An insignificant groove is left between the ridge and the seal, which is necessary for ventilation.
Sealing of junction nodes
Decking, the dimensions of which are indicated in the article, involves the installation of sealed joints between the material and the wall during installation. In this case, angle strips that have an obtuse angle should be used. After the lath has been laid in the lap, it must be fixed with screws to two surfaces, one of which is a wall, the other is a roof. If you plan to equip the transverse abutment of this bar, then it should correspond to a right angle across.
