Technology of roofing from corrugated board. Installation and installation instructions

The technology of roofing from corrugated board has again become of interest to private developers and professional builders after the material has found a new technological coating based on polymers. This allowed the creation of roofing systems that are immune to external aggressive phenomena. In addition, the corrugated board with a one-sided or bilateral 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 light weight, the latter of which allows to work on the arrangement of the roof without involving heavy equipment.

If you are interested in the technology of roofing from profiled sheeting and you do not have the appropriate skills in doing this kind of work, you can use the instructions that are attached to the material. This will greatly simplify the work process. By purchasing corrugated board, which is produced under the marking of HC35 or HC44, you can perform installation of a roofing system of a gable type. With a single-pit system, which is usually installed in baths, garages, storerooms or sheds, things are simpler.

Material selection

The technology of roofing from corrugated board requires 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 eaves that the roofing sheet is calculated . It should be taken into account that the profiled sheet, which is realized in rolls, can have a length of 12 meters. The height of the corrugation guarantees strength characteristics and is described in the marking. So, if you buy material marked with HC35, then the canvas will have a wave height equal to 35 mm, whereas a sheet under the marking HC44 has the mentioned parameter equal to 44 mm.

The technology of roofing from the corrugated board provides for determining the load on the roof system, this index will depend on the angle of the slope of the ramp: the larger it is, the greater the load. With a more impressive angle of inclination, the thickness of the sheet of roofing material increases.

Selection of additional parts

Roof from profiled sheeting, the installation instructions of which must be known to the master before starting work, requires the use of fasteners. Self-cutters with the size equal to 4.8x35 mm are used as it. Fasteners should be with a washer, which is made of neoprene rubber. Whereas for the arrangement and fixing of the elements of the ridge, it is necessary to use fasteners, the size of which is 80 mm and more. You need at this stage and rivets, but you need to choose those that correspond to the hue of the coating. By purchasing profiled flooring, you will receive additional structural elements, among which you can distinguish:

• The end plate;
• parapet;
• The wind bar ;
• Horse;
• Valley;
• Curtain rod.

In order to work on the rules, it is necessary to include a heat and water insulator in the roofing system, the latter 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, you need to use mastic.

Positive features of profiled sheet

Roof from profiled sheeting, the installation instruction of which provides for the use of many materials, will ultimately have a mass of positive characteristics. Among them, you can identify the suitability for mounting any angle of slope, as well as cost-effectiveness. In addition, the coverage will be really high-quality, and the work will be possible in the shortest possible time. The process will not be accompanied by special difficulties, and during the operation the coating will easily be repairable. If necessary, profiled flooring can easily be removed, and then installed in its place. Before the start of the process, the profiled sheet is easy to transport and store.

The technology assumes the need for cutting the sheet. This process is not difficult, as far as drilling is concerned.

Calculating the amount of material

In order to produce the works described in the article, you need to know in advance how much material is to be purchased. To do this, the roof calculator from the corrugated board is useful, but you can make such calculations yourself. To do this, it is important to first determine the area of the roof to be covered. For this, the length should be multiplied by the width. After the same method, the area of one sheet of corrugated board is determined. Then the first indicator should be divided into the second one. This will allow you to get the number of sheets you need to purchase.

However, when carrying out the calculations, it is important to take into account that the installation is performed with some overlapping of the sheets, in addition, the allowance should be equal to 5 cm. That is why it is necessary to add about 15% to the figures that were obtained during the calculation. It is important to purchase the necessary amount of fasteners. It can be calculated if we take into account that approximately 8 units of fasteners will take about one square meter.

Arrangement of the roofing

During construction work, be guided by SNIP. Roof of corrugated board will be durable, if you follow these rules. According to them, starting work on the arrangement is necessary with the installation of the crate. It is on it and will be attached to the roofing material. Previously, a vapor barrier film is to be reinforced on the rafter, but it is important that the material be reinforced with some sagging, which is approximately 20 mm.

Begin to make work on fixing the film from the eaves, it should be overlapped, the width of which is approximately 15 cm. But the fastening of the cloths is done by means of nails, which are driven into the rafters. Whereas from joints it is necessary to get rid by use of an adhesive tape. This will eliminate the occurrence of condensate when the temperature changes.

In the process of work, it is necessary to take into account SNIP. Roof of corrugated board in this case will be equipped with technology. Among the requirements can be identified the need for processing the crate antiseptic. This applies to the rafters. The elements of the crate must be installed in the longitudinal direction. From below, the board will be reinforced along the cornice, it should have a more impressive thickness.

If you correctly install the crate, then you will get a solid roof, the zinc-plated 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-pit system with a slope of less than 15 ^° . Installing the bars should be at a distance of 25 cm. Whereas with a more impressive slope the lath must be continuous.

Roof installation

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 between 700 rubles per 1 m ² . It is necessary to start work in dry, windless weather. You can lift the sheets using ropes. To begin to fasten sheets it is necessary from the bottom row and a pediment, that is true, if the size of a cloth provides presence of an overlap. It is necessary to form the overhang from the ledge, which is equal to 30 cm, and the pediment one, equivalent to 7 cm. If the cloth does not cover the entire roof, it is permissible to use several sheets.

Profiled sheeting, the size of which can be different, is attached from below and along the sides, into the hollows. The vertical lapping should be equal to 20 cm. The obtained lumen is sealed with a sealant. Choose when buying a sheet with a width of 800-1200 mm.

Installation of additional elements

As for the additional elements, they are used for different purposes. For example, such additional elements for the roof of profiled sheeting, like end plates, are used to protect against wind. Their installation begins from the eaves, and they should be taken out to the roof ridge. It is necessary to do this after the skates have been fully covered, so that about 5-10 cm is to be built up. Their fixation is made to the end of the pediment and to the roof, the distance between the fasteners should be equal to 1 meter.

Installing the ridge straps

There are additional elements for the roof of profiled sheeting, which are called the slats of the ridge. Their installation is made lapped, which is 20 cm, but no more. Use an additional seal. Between the ridge and the seal is left a small groove, which is necessary for ventilation.

Sealing of junctions

Profiled sheeting, the dimensions of which are specified in the article, assumes, during installation, the sealing of the junction points of the material and the wall. In this case, it is necessary to use angled strips, which have an obtuse angle. After the lag is laid overlapping, it must be fixed with screws to two surfaces, one of which is a wall, the other is a roof. If it is planned to equip the lateral abutment of this bar, then it should correspond to the right angle in diameter.
