Installation of corrugated roofing itself

The construction market offers a wide choice of various roofing coatings for buildings and structures. One of the traditionally popular roofing materials is profiled. It is available in a wide range from which you can always choose the appropriate option for your roof.

Before purchasing a coating, it is necessary to make a calculation based on the measurement of the overlapped area, taking into account the necessary margin for overlapping, trimming and waste. After calculation, sheets of profiled sheeting are purchased in the required quantity, as well as related materials and products. Then installation of corrugated roofing is performed.

Raise the sheets on the roof need to use boards or lag of a certain length. In windy weather, the installation of corrugated sheet is not recommended, as a sheet of air can be torn out with a gust of air masses from hands or from an unsecured installation site. The protective film from the sheets must be removed immediately after installation. Cut sheets Bulgarian grinder undesirable through the possibility of the development of a section of corrosion.

Necessary materials

To cover the roof with roofing material, professional flooring, self-tapping screws, compactor, ridge, wind strip, as well as in hotel cases end bands and corners are used:

• Light roofing is covered with sheets of corrugated C35 or C44 waveform or trapezoid. The minimum length of a product is 2 m, maximum - 6 m. The length can be adjusted by individual order. It is advisable to install sheets CH35 on the pitched roof, and it is better to cover the supporting structures with products of N.
• Polymer coated screws must match the color of the sheets. So they will visually blend with the color of the sheeting. The tip with the properties of the drill can be fixed to the design of metal with a thickness of 2 mm. When selling screws must be equipped with sealing washers.
• The sealant acts as a sealant for gaps between roofing sheets and other structural elements. Due to its flexibility, it fits well into all curves and protects the space under the roof from moisture and dust.
• The ridge, which can be rectangular or semicircular in shape, connects the edges of the profiled sheets and performs a decorative function.
• Wind strip blocks walls from precipitation and makes the roof more attractive.
• In the valley, the plank from the bottom does not let in water, and from above it complements the construction.
• The inner and outer corners of the sheets are connected by corners.

The roof structure of corrugated board except the material itself consists of ventilation, steam, hydraulic and thermal insulation. Each element performs its specific function, which ensures the reliability of the entire system:

• In order to keep moisture out of the insulation, vapor barrier is used. It is a special film that fits on the inside of the roof with a stapler in the horizontal direction. The resulting assembly seams are fastened with adhesive tape.
• After the vapor barrier there is a layer of insulation that compensates for the difference in air temperature and does not allow condensation and moisture to accumulate under the roof of the structure. The thickness of the insulation, stacked between the rafters, depends on the region in which the building stands. In any case, it is desirable to choose a heater with a thickness of 0.2 m.
• The "pie" is completed by a waterproofing windproof membrane, which plays the role of an auxiliary insulator. Since it is waterproof, it has the ability to protect the system from condensation. Waterproofing, due to its properties, contributes to the durability of the roof. The membrane is unwound vertically from bottom to top from the eaves to the ridge mounted on the rafters, while observing an overlap of 0.15 m.

Stages of work

Lathing for corrugated is done either with a certain step, or completely blocking the structure. The pitch of the batten depends on the slope of the roof - the smaller it is, the greater the distance between the slats. If the bias is 14? and less, wooden blocks are mounted in 0.35 m increments, in the case of a slope of 16? and more - the slats are fixed at a distance of 0.55 m.

Install sheets on the roof begin in the direction of the bottom-up - this does not allow water to leak through the joints between the roofing products. Corrugated sheets are also mounted in the direction against the wind. In its definition, you need to focus on the rose of the winds for a particular locality. If the air masses mostly move on the left side, the roof sheets are laid from right to left, and vice versa.

Note! Work with corrugated roofing is necessary only in non-rigid shoes and move only along the deflections between the arcs.

In the case when the length of the sheet allows you to completely block the slope, sheeting begins to be mounted from the end of the roof. The eaves are decisive for alignment, taking into account its overhang - this is about 4 cm. It is forbidden to align the sheets along the edge of the butt.

The initial sheet of a professional flooring lays down on a certain place and is fixed by the self-tapping screw near the center. The following product is installed on the first sheet overlapped and fastened in the same way. Having laid profiled on the entire bottom of the roof, it is leveled along the eaves line of the horizontal. When the turn comes to the installation of the roofing sheets near the ridge, for their reliable connection, the fastening takes place through one arc deflection.

Because of the possibility of damage to the hands by the sharp edges of the roofing sheets, the work must be done in thick gloves.

After pre-laying comes the turn of the final fixation. In the vertical direction, the screws are screwed through the 1 lath of the batten. In the horizontal direction - through 1 wave to the deflection of the roofing product. At the edges for attachment use each strap crates. Down at the eaves and at the top of the ridge, the screws are screwed into all the bends of the sheets. The joints between the products are filled with hardware along the entire length, despite the relief.

Unnecessary fragments of the roof are cut off with an electric saw or scissors. The same operation is performed at the ends of the building and on the opposite side of the ramp in the presence of a gable roof.

Then a bar is installed on the end face and is fixed in the wave crest with the same screws. When moving up the overlap of the bars is made in the size of 5 cm, the distance between the fixation - not more than 1.0 m.

At the final stage mounted horse. Between the lower part and the top of the corrugated sheet, it is desirable to lay the seal with self-adhesive properties. Skate bars overlap with an overlap of 0.1 m, the distance between the fixings reaches 0.3 m.

Installation in difficult places

Structurally, complex elements often form valleys, which are called internal angles. In addition to them, chimneys, vents and parapets come out onto the roof. The joints of mounting materials in such places should be well sealed to avoid water entering the space under the roof.

In places of formation of the valley, the crate should be made solid on each side of the gutter. The bottom bar is fixed at the edges with nails or screws. If the bar is increased, an overlap of 0.2 m is applied. The bar in its upper limb is bent at the ridge of the roof. Between the bar and the roofing material, it is desirable to put a seal or apply a special sealant of mastic. The final fixation of the strip on the corner is made together with the fixing of corrugated board. The top bar is mounted on the sheet, performing a decorative function. In addition, the stitch sews the joint between the edges. It must also be installed using sealing materials that cover the joints from moisture.

In the area of ​​the pipe, the crate is also constructed in a continuous manner, so that the apron can be easier to run in to the smoke outlet with dowels at a distance of 0.2 m. To the crate, the junction bar is attached with screws. The apron from the bottom can be arranged in a small shtrob, previously made in the brick base of the pipe. The joint must be sealed. A sheet of corrugated sheet is installed on top. To install the upper bar stitching groove is not necessary. It is mounted after fixing sheets near the pipe. The same method is used for transverse and longitudinal docking of ramps to the wall. Now, finished products of various necessary forms are being made, therefore laying of corrugated sheets in difficult places is done without any particular complications.
