Installation of the profiled sheet on the roof: the cost of work. Installation instructions for roofing from profiled sheet

Profilist - the material is inexpensive and at the same time reliable. In addition, its advantages include simplicity in installation. Mounting such sheets on the roof will be completely uncomplicated. On how to do this, as well as on how much the cost of the work may cost, and we'll talk further in the article.

What is a corrugated sheet?

Before you start to understand how to mount the profiled sheet on the roof, let's see what, in fact, is this material. Also, you first need to determine its type. A corrugated sheet of metal, coated with zinc by the method of cold rolling, is called corrugated sheet metal. On top of the steel is applied a paint and varnish coating. Sometimes the corrugated sheet is covered with a polymer decorative protective layer. At the moment, several of its varieties are produced. To cover the roof you need to take roofing sheets of the brand H35 - H114.

Drafting of the project

Before proceeding with such an operation, as mounting the roof from the profiled sheet, draw the necessary drawings. Usually the roofing project is included in the project of the building itself. However, it is far from superfluous to make a separate drawing of the roof in the profile and frontal surface. You can also draw a plan for the roof and its sketch. In this case, it will be easier to avoid errors during the erection. Of course, the first thing to do is to determine the angle of the slope of the ramp. This indicator directly depends on what kind of wind and snow loads can act on the roof during its operation. The easiest way to determine the angle is by using special tables.

Also it will be necessary to calculate the length of rafters, runs, mauerlats, etc. Well, of course, you will have to perform calculations of roofing material. The length of the rafters is calculated using trigonometric functions. To determine the number of required proflista, first calculate the area of the skates, and then the resulting figures are summarized.

How much can it cost to install a profiled sheet on the roof

The simplest way to determine the price of roofing with this material is the use of special computer programs.

So, how much exactly can the installation of the profiled sheet on the roof. The price of such work directly depends on the area of the skates. The calculation of the required number of sheets is made by simple division. Based on their cost, determine the final amount. Among other things, the cost of skates, rails, aprons, ventilation elements, snow chains, drainage system, end plates, etc. will need to be added to the result obtained.

The cost of one sheet of corrugated board, depending on the thickness can be from 150 to 250 rubles (for 2015). The meter of the ridge element usually costs about 200-250 rubles.

So, you figured out how much it would cost to install the proflist. The price for the construction of the roof itself will add up, including the cost of the rafter system. Also, the final amount depends on how much you have to pay for the waterproofing film, as well as fixing materials.

Well, of course, the cost of the roof will depend on how much material will be needed to build the rafter system.

Roofing system

Installation of the roofing profiled sheet must be carried out on a reliable crate. First, of course, rafters are being built . This work is carried out in several stages. After the walls are erected, the Mauerlats are laid on them. To fix them, anchor bolts are poured into the reinforcement belt. For Mauerlates, a bar with a section of 100 * 100 mm is usually taken. He is lifted to the wall, put on bolts and taped with a hammer. Drilled holes are drilled on the resulting marks. Then the mauerlates are fixed on the wall.

After that, they begin to install racks, and then cut and mount rafters. The fastening of the latter is performed on the nails with a "knot" or on the corners. For greater reliability in them, you need to cut out the landing nests.

Waterproofing

Before performing such an operation, as mounting the profiled sheet on the roof, the latter must be waterproofed. To do this, the strips are horizontally attached to the strip of polyethylene film. Fix them on their feet with the help of bars. The overlap between the individual strips should be about 15 cm. The film is fastened with a small sag (no more than 2 cm). The fact is that when shrinking the building, as well as during a strong wind, the elements of the rafter system can move slightly. If the film is stretched too much, it may just tear.

Installation of the profiled sheet must be carried out on a reliable crate. You can make it, for example, from a board. Do not take too wide. The fact is that such boards are more prone to deformation and cracking. The board is stuffed with nails (two for each bar).

Gasket of the battens

The lining under the corrugated sheet must be continuous only when the angle of inclination of the ramp does not exceed 15 degrees. In all other cases, the boards are packed at a certain distance from each other. Specifically, the pitch depends on the thickness of the roofing material. Usually it is 30-60 cm. The optimal option is a step of 50 cm. Mount the crate starting from the bottom. In each fastening beam, two nails must be driven in.

Fastening of the bottom marks

Mounting valley at the roof with a profiled sheet first of all. Fixation is made on self-tapping with a step of half a meter. Installation starts from the bottom up. The overlap between the elements should be about 15-20 cm. In the future, between the profiled sheet and the bottom end, you will need to lay a sealant. The profilist is mounted at a distance of 10 cm from the central part of the valley.

Installation of roofing material

After the crate is ready, proceed, in fact, to perform such a procedure, as mounting the profiled sheet on the roof. First install a curtain rod. Its edge should protrude beyond the ramp by 3-5 cm. A sealing tape is placed between it and the profiled sheet. The easiest way to cut the sheets is with a circular saw. However, this method is suitable only for a material without a polymer coating. In the latter case, use metal scissors.

Sheet alignment is performed at the bottom edge of the ramp. In this case, the overhang will be even. The procedure for mounting the profiled sheet is as follows:

• The first sheet rises to the roof, aligned in such a way that the overhang remains 4 cm, and fixed at the ridge on one screw.
• On the roof rises the second sheet and aligns on the first.
• After that, the sheets are fastened together with self-tapping screws along the crest of the wave in steps of half a meter.
• Next, another sheet is raised and also fixed at the ridge and attached to the second.
• After that, all three sheets are aligned once again over the eaves and fastened to the crate by screws. To the crate, the sheets are fixed at the bottom of the wave, after three.

In the event that the angle of inclination of the ramp does not exceed 12 degrees, the joints of the sheets are laid with a sealing tape.

How to fix a skate

As soon as the process of mounting the profiled sheet is finished, proceed to the fastening of the ridge. Fix it to each top of the wave without a seal. Between each sheet and the top edge of the rafters should remain at least 5 cm. Thus, under the ridge there will be space for ventilation. The skate is fastened to special roofing screws.

Assembling of upper ends

The upper valley is also beginning to mount from the bottom up. The lapping in this case should be 10 cm. Fixation, just as in the case of the lower valley, is performed on roofing screws with a step of 50 cm. The sealant is not installed in this case.

How to fix a pediment

The cost of installing the roof from the profiled sheet will also include the cost of the material necessary for sewing gables. At its purchase it is necessary to consider that in this case at a cutting will be a lot of waste.

Mount the sheets on the pediment best of all with a wave across. In this case, the roof will look more attractive. First, the material is cut out, and then fixed with screws to the pre-filled crate of the timber. The ends of the pediment are closed with special slats, which are fastened to the screws with a step of half a meter.

Pipe apron fixing

Between the chimney and the profiled sheet, small, but crevices, always remain. Later, during the rain, they get moisture. To prevent this, the pipe should be wrapped with a special apron. It is set as follows:

• The apron straps are applied to the pipe.
• Further on they are marked.
• Strokes are made about 2 cm deep.
• The apron is started from the bottom. Self-tapping is used for fixing. The overlap between the elements of the apron should be 15 cm.
• Stroiba after installation is washed from dust and filled with sealant.

How to fix snow holders

On steep slopes, snow accumulates in winter, first, and then "avalanche" descends. Of course, this is quite dangerous. In addition, on the roofs equipped with drainage systems, snow clogs the gutters. To prevent this from happening, special snow-holders are installed on the roof slopes. The set consists of the very strip, which detains the "avalanche", and the corners. Mount snegozarzhateli at a distance of about 35 cm from the eaves. On the corrugated sheet a special seal is placed under the bar. Mounting is performed at the top of the waves. The self-tapping screw must be screwed to the bottom edge.

Well, now you know how the roofing is made from the profiled sheet. As you can see, the operation is not as complicated as it might seem at first glance. If you want to do it yourself and save money on hiring a brigade, it will not be difficult.
