Roof from metal: self-assembly technology
Roofing of metal, the installation technology of which will be described in the article, is an excellent solution if you want to create both a cold and a warm roof system.
Features of the arrangement of the roof
If there is a need for mountinga warm system using tiles, it is necessary to insulate the stingrays. This will allow you to get a mansard room, suitable for living. Be sure to provide protection against condensation, which can occur on the internal surface of the system. In order to prevent such phenomena, it is necessary to apply a waterproofing, which is often used as a membrane that benefits from films in the struggle for quality, because the membrane is permeable to steam, which prevents the accumulation of water. With the use of such superdiffusion materials, you will have the opportunity to save considerable space, as the installation of the webs should be carried out without providing a gap.
Additional materials
Roof from metal, installation technologywhich is described below, requires the initial isolation of the valley. You must start from the top. Conjugation on the closures and roof valley construction should be eliminated tape. In the case of the rafter insulation must be laid from the eaves to the ridge, wherein the material web to be rolled from left to right. The joints of adjacent rolls are to be installed on the rafters, making the overlapping width of 15 cm. Be sure to remove any slack webs.
Once you are finished with the waterproofing,you can proceed to laying the thermal insulation layer. As a rule, basalt cotton wool is used for this, however you can choose the material yourself. Mats insulation are mounted between the roof rafters. If there is a need to lay several layers, then you must make a stitching method. This means that the seams of the first layer must necessarily overlap with the plates of the second layer. Otherwise, you will get bridges of cold, through which cool air will flow.
The next layer will be a vapor barrier. Its purpose is that the evaporation coming from the interior space of the premises, do not stay in the heater and do not become a pair of water.
Installation of cold roof using tiles
Roof from metal, stacking technologywhich must necessarily be studied before starting work, can be cold. In this case, the slopes are not subjected to thermal insulation. Heat insulation is applied only to the lower area of the attic. This ensures that the house will retain heat, while the under-roof space will be well ventilated.
In addition to the membranes, a cold roof of tile canTo be mounted using a water resistant film. It is laid with some sagging: between the rafters there should be approximately 20 mm of sag, this will contribute to the drain of accumulated condensate. Waterproofing in this case, too, is laid horizontally, it is necessary to move from the eaves to the ridge, while ensuring an overlap of 15 cm.
Creation of a system of crates
Roof from metal, stacking technologywhich should be known to the master, presupposes the presence of a crate. For its installation it is recommended to use blocks 50x50 mm, as well as edging board 32x100 and 50x100 mm. In the lower part of the ramp - along the cornice - two boards with a section of 50x100 mm should be strengthened. After the insulation is laid on the counter, where you need to use bars 50x50 mm. They need to be fixed along the rafters, starting from the ridge and gradually moving to the bottom.
Then you can proceed to the device of the crate,which is fixed over the counterbridge. Fastening of system elements must be done horizontally. The distance between the boards depends on the profile of the roofing material.
The top area needs to be done a fewmore solid. This requires a roof of metal. Technology, with their own hands, involves fixing two boards on each side of the ridge. In the valley valley, the lathing should be mounted in such a way that it is continuous.
Laying of metal tile
If such a device is proposed for the roof,painting metal ramp will close completely, the attachment should be started from the ridge. The first sheet should extend beyond the ledge by about 5 cm. When you are ready to commit roofing webs. Thus it is necessary to provide an overlap. Once able to install in its place three sheets, check the correctness of their position relative to the eaves. Such an analysis should be made with the same frequency until the completion of the work. roof mount technology involves the use of metal as the mounting fitting screws which are screwed into the bottom of the wave profile.
Features of mounting end plates
From the end of the roof should be mounted endelements. Their fastening should be made by screws, observing a step of 60 cm. In addition, it is necessary to make a lap width of 50 mm. As ridge bars you can choose flat or rounded elements. The first assume the need for additional fixation of the plug to its own end. It can be ordinary or conical, and fixation should be made with rivets, there is also an alternative solution - self-tapping screws. Before proceeding with the installation of the laths, it is recommended to lay a sealant under the ridge, which can be either figured or universal.
Additional Items
Technology of roofing from metalprovides for the installation of vent vents in the spans between the rafters. If the house has a ventilation system, then its output should initially be combined with the riser. For this, a corrugated pipe is used. On the roof for installing the passage element, you must cut and remove the roofing element. After laying the insulation, sealant, as well as the sealant, the ventilation system outlet must be inserted into the formed hole and fixed to the tile with self-tapping screws.
The device of the chimney
If you decide that your house will have a roof ofmetal, technology, chimney and all the other elements on which will be equipped, should be carefully studied. So, in order to aesthetically bypass the chimney pipe, the latter can be plastered and qualitatively combined with waterproofing. tile sheets, which are arranged at the sides of drain should be marked and cut cleanly through punching, it is necessary to comply with this step of the material to a pipe 15 cm. Now it is possible to mount the apron. Initially, it is recommended to complete the work with the side elements and only then proceed to the rest. When fixing the side aprons, it is necessary to ensure the overlap of at least one crest of the sheet wave. This indicates that the side that is in contact with the roof must be 20 cm or more in width.
Installation of a steel frame before installation of a metal tile
Your roof of metal on metalprofiles can be arranged. For this, I-beams, channel bars and corners should be used, based on a profiled metal. According to the form, these elements can be triangular, rectangular and trapezoidal. Before acquiring the components of such a framework, it is necessary to take into account all its positive and negative sides. Among the former, longevity can be distinguished, while among the latter, the complexity of transportation and the more imposing labor costs associated with installation, which is associated with considerable weight.
Using steel trusses, you canto cover the spans of 50 m. As a rule, the installation of these components of the system is carried out on top of farms that are located under the lines and have a rectangular shape.
The formation of a steel framework must be maintainedafter installation of the support of reinforced concrete columns, steel or concrete pads reinforced with reinforcement and fixed on a brick wall. Roofing of metal tiles, the laying instructions of which should be known to you before the beginning of work, is fixed in the area of steel rafters with metal kerchiefs, welded or tightened bolts. All these recommendations are justified for a private developer, while professional companies use hot rolled pipes, the profile of which can be completely different. Such pipes have very little weight, which is explained by the use in their production of a material whose thickness does not exceed 5 mm. This is much less than the metal used in the manufacture of other profile products.
Special features of mounting the dormer
If you decide that your house will have a roof ofmetal tile, technology, the dormer window assembly on which will be made out, should be well studied by you. At the same time, it is necessary to take into account that the frame for this element of the roof will also be needed, and it will have to be sheathed using the same technique as described above. Doing the system of the roofing for the window is necessary in parallel with the installation of the main frame. The dormer window should have the same rafters, crate and skate. In the process of installing rafters at those points where it is supposed to locate the dormer windows, it is necessary to provide openings enclosed by rafter legs. This will strengthen the system. After the rafters need to mount the crossbeams. On the beam, which is located from the bottom, it is recommended to fix the vertical posts, connected with the transverse bar. The frame must be connected to the upper beam. This will get the frame of the window.
Insulation of the ventilation duct
So, in your plans - a roof of metal. The technology, the unit of the duct for the ventilation outlet through which it will be installed, must be strictly observed. This will make the work qualitatively. Thus, the venting device, or rather its box, must be accompanied by waterproofing works. To do this, you can use liquid sealants for external work. This will prevent moisture from entering the space under the roof. As an alternative solution for insulation of the ventilation box, it is possible to consider such materials and elements as silicone, membranes, as well as clamping bars. Otherwise, it will not be possible to avoid leaks, which will inevitably entail a violation of the structure of the roofing cake and the infiltration of water into the internal space of the premises of the house.
If you can not do it yourselfinstallation works, roofing from metal turnkey can be equipped with professionals. This ensures an excellent result, and hence, a long life of the system.
