Installation of the roof roofing on the rafters. Installation of the shed under siding. Installation of the roofing for metal tile

The construction of the foundation for roofing is considered to be the smallest part of the work in the list of basic construction activities. The foundation, the erection of walls and partitions usually require great effort and material investment. Nevertheless, the roof is the most important component in the construction of any building, therefore it is necessary to approach the implementation of this activity responsibly. Loads in the form of precipitation, wind gusts and other mechanical influences can disrupt the integrity and integrity of the roof. Therefore, it is necessary to carefully approach the creation of a foundation on which the roof will be fixed in the future. Installation of rafters and crates is considered by specialists as the most significant stage on which the reliability of roofing depends. There are different approaches to the installation of this part of the design, the choice of which is largely determined by the characteristics of the final flooring.

Installation of rafters

Even a qualitatively installed crate does not provide the necessary supporting function if its installation was carried out on a weak truss system. Therefore, it is important to properly mount it.

First of all, the Mauerlat - beams, which will form the basis for the sections of the structure. The optimal option involves the use of a single mauerlat, fixed with anchor bolts. Next to the installed elements fasten the rafter feet. Then you can start assembling the sections. The choice of the configuration of their location and fixing each other is determined by what will be the installation of the roofing of the roof of the house.

On the basis of the general plan, a drawing is drawn up, after which the construction is assembled on the ground. The ready system needs to be lifted to the roof - this is usually done by means of a winch. When one of the sides is pressed as much as possible to the base of the building, it can be released from the cables and fixed with screeds and bolts. The base of the fastening will be corners with bolts, which will reliably fix the rafters to the Mauerlat.

Underlayment of the underlay membrane

A common mistake many inexperienced roofer is ignoring the isolation measures. Just on the quality of this stage and depends the tightness of the roof, the lack of dampness in the attic and overall comfort in the premises. After installing the rafters, you can proceed with the installation of suitable protective materials. Regardless of the technique by which the lathing will be carried out, the structure can be isolated in the lower part by means of superdiffusion membranes. This layer will ensure water vapor permeability and waterproofing. But it may not be the only under-roofing material - sometimes the membrane is supplemented with a heater. The process of laying such a coating is of no particular complexity. The membrane is supplied in the form of rolls, which are spread out in the workplace and are laid throughout the entire area of the rafters. The strips can be overlapped, and fixing can be done with glue or special hardware.

Nuances of choosing wood for crates

The selection of materials for the supporting structure under the roof should be approached carefully, and especially with regard to wood. It is desirable that the installation of the battens be made of coniferous material, for example, spruce and pine. This is an easy-to-handle wood that will provide flexibility and durability during the operation of the roof. It is important to take into account the material grade. Of course, the ideal category will be the first category, but if financial opportunities exclude such an acquisition, then you can confine yourself to the second class. However, such elements of the structure must first be treated with antiseptics.

Another significant parameter of choice is humidity. If the inside is supposed to be protected as a drywall coating, then wood can be used with a moisture content of no more than 20%. If it is planned to install a crate, some of which will have direct access to air, then the use of wood with humidity of more than 20% is not ruled out.

Edging of the battens for siding

For the installation of siding panels, it is better to choose a wooden crate. This choice is justified by the flexibility of the material, which will not allow the external coating to deform. In the process of installing the elements, it is important to maintain uniformity, that is, all racks must be in the same plane. The fastening is done by clamps-suspensions or by usual nails. If the base has unevenness, then the position of the carcass can be adjusted with the help of wedges. Typically, the installation of the battens for siding is performed with a step of 20-30 cm elements. But in each case, you should calculate this distance individually. The larger the working area, the longer the indentation - this is the basic rule that roofer guides in this design.

Edging of the roofing for metal roofing

The complexity of the structure of the frame under the metal tile is due to the fact that the profiles can have different corrugations and size. By the way, siding in this sense is more standardized. If a continuous crate is planned, then it is better to use planks with parameters of 3.2 x 10 cm or blocks of 5 x 5 cm. Fixation is made close to the base in steps of 10 cm. Such a short spacing is connected with the fact that the corrugated board is one of the heaviest roofing materials . Accordingly, the installation of the crate for metal tiles must take into account the high load on the structure. For fastening, nails with a thickness of 3 mm can be used, while their length should be twice the cross-section of the board. A feature of the installation of the frame under the metal tile is the wide presence of metal fittings. Various staples and corners, serving as an additional means of attachment, are most common in large roofs. If a standard two-stage system is planned for a small house, then it is quite possible to do with racks, which are fastened with a frequent step by means of nails.

Installing the roofing under the soft roof

The device of a soft roof can be called the most demanding and even capricious kind of such works. This material is laid on a flat solid flooring, so the crate will be performed in two stages. First of all, the frame is mounted. Its features are a frequent step of the rails and extreme accuracy. Further, a smooth protective coating is formed, on which the soft roof will later lie. If the installation of roof roofing can be carried out using the same bars and rails, then as an additional flooring should use chipboard, plywood or other wood-shaving material with similar characteristics. The main thing is that the original design of the rafters was well isolated. In addition, the ends of the base must be rounded to ensure a smooth transition of the decorative roof.

Features of installing plastic crate

Usually, metal is considered as an alternative material for the lathing device. Wood does not always allow you to achieve the required strength, so it is replaced with profile elements. However, in some cases, a plastic crate is permissible, the installation of which assumes some differences, but in general the attachment technique remains the same. Fixation is carried out through special holes in the elements with the help of bolts or self-tapping screws. But the feature of the plastic panels for the battens is that their design allows more reliable attachment to the rafters using a groove system. There are different models of such elements, which should be selected specifically for the requests of a particular roof.

Installing the control unit

According to the design, this type of crate is in many ways reminiscent of the traditional frame, formed by rails or boards. The principal difference is the additional strengthening of the system due to the insulation of the roofing material. It was already noted that the design should provide for the presence of a heater and a vapor-proof membrane. But in this case, the function of protective under-roof barriers increases. That is, first the roofing material or other material with similar properties is laid, and then the installation of the crate onto the rafters over the insulating deck. The configuration of the arrangement of elements can be both sparse and solid. The main thing is to provide sufficient space under the roof to prevent the formation of condensation. This is especially important when fixing wooden slats, on which accumulating moisture acts destructively.

Conclusion

A variety of materials for the creation of roofing defines the requirements for both the rafter system and the supporting frame. In turn, the installation of the crate can not be performed without taking into account the operational requests to the final coating. For example, metal decks require a higher degree of reinforcement of the structure. In this case, it is important to provide a high-quality material for the creation of a crate, capable of withstanding atmospheric influences. For siding - on the contrary, physical strength is not so important, and the flexibility of the carcass comes to the fore, which is ensured by properly selected racks.
