Is it possible to qualitatively cover the roof trapezoidal sheet, while not having any skills? My experience has shown that it is possible. Below, I'll detail how to do it, and step by step instructions visually confirm my words.

Procrit roof floorings under the force of each handyman - just need to comply with the technology

## mount technology

The process of installation of corrugated board with your hands can be divided into three stages:

Next, in order, consider how to cover the roof.

### Step 1: Calculation and preparation of materials

First it is necessary to count the number of sheets of material. To do this, first measure the area of ​​the roof.

Calculation of corrugated board is done by a simple formula K = Skr / Sl + 10%, where..:

• K - the number of sheets of corrugated board;
• Skr. - the roof area;
• Sl. - the area of ​​a single sheet of corrugated board.

Steel sheet can be of different sizes

The stock material (10-15 percent of total amount) is required since during installation will necessarily remain corrugated waste. In addition, the need to ensure an overlap of the width and length.

If the ramp length corresponds to the width of the sheeting, then count the number of sheets even easier - the length of the ramp should be divided by the width of the sheet, and then multiply the resulting value by the number of rays and add 10% of the total sheets.

The durability of the roof depends on the compliance of waterproofing and installation of lathing technology

In addition to the roofing material you will need these materials:

 Illustration materials Wooden slats. The cross section of 20x30 mm; Board. 50x30 mm; Waterproofing membrane. Additional elements. These include ridge profiles, wind braces, valley, abutting strips, etc .; Sealing tape for corrugated board; Screws for corrugated board with sealing gaskets. Matched the color of the roofing material, which makes them invisible on the roof.

The calculation of the required number of strips for kontrobreshetki very simple. Count the total length of the rafters (length of one rafter multiply their number). Such should be the total length of the strips (split length trusses on one rail length).

Boards are mounted along the length of the ramp. Step battens should be 500-600 mm. If the angle of inclination of the ramp does not exceed 15 degrees, it is necessary to reduce the step crates up to 300-400 mm, as the roof load will increase.

### Step 2: installation of lathing

Before you cover the roof floorings, it is necessary to seal the crate and perform correctly. This operation is carried out as follows:

 illustrations Description of work roof waterproofing: Secure the first strip of film on the rafters, placing it crosswise slope. To use the stapler fixing film; When installing the subsequent strips provide overlap of about 15-20 cm; Glue joints waterproofing tape. Installation kontrobreshetki: Cut the rails along the length of rafters; Secure the rail to the rafters with nails or screws. Mounting battens: Kontrobreshetke nailed to the board, aligning it with their hands on the lower edge of the ramp; Back down on the first board 300-600 mm, and parallel to nail the second board. So runs a crate to the roof ridge. Thus do the crate on all slopes of the roof. In the process of mounting battens may require alignment, since drops more than 10 mm is unacceptable. To align the sheet under the bars of the board. In places stingrays interface, which will be installed the valley, as well as around the perimeter of the passage of chimney and ventilation ducts need to do a solid crate, ie with zero pitch. Construction of gable overhangs: Batten boards, output beyond the gable 40-60 centimeters; Connect the board overhang cross beam or boards, as shown in the photo.

By lowering the temperature waterproofing film is strongly stretched. Therefore, during its installation, be sure the sagging between the rafters at the centimeter and a half.

### Step 3: installation of profiled sheet

Roof trapezoidal sheet roofs is carried out as follows:

 illustrations Description of the action performed Installation of curtain elements. First of all, secure the edge of the ramp Cornice strip and mount the drain. Assembling first sheet: Align the first sheet along the edge of the ramp; Provide overhang profiled sheet about 40 mm; Secure sheet screws. If the width of the ramp will be installed a few sheets, perform works from the bottom up. Mounting the second sheet: Place the second shaped sheet so that it is first blocked at the same wavelength; Sheet aligned with the edge of the ramp; Connect the second sheet to the first, screwing screws into the top of the wave pitch of 20 cm. Screws must not touch the crates; Attach a second sheet of screws to a batten. Thus, mounted entire first (bottom) row of sheets. Laying the second series of sheets: Before fastening the topsheet, put on a cross-section of the joint sealing strip, as shown in Picture example; Lay a first sheet of the second row overlap with the lower 100-200 mm, depending on the inclination angle; Sheet aligned with the edge of the eaves; Secure sheet screws. Installation of the valley: In the joint between the lower valley rays fix screws; Lay the corrugated sheets so that they hung over the valley strip 10 centimeters. Mezhuyev Bent bar and be sure to lay the sealing tape; To attach the upper trapezoidal sheet roof valley by screwing screws in up corrugated wave. Installation of junction strips. If the square chimney passes through the roof, the work is done as follows: By perimeter of the pipe is performed Grooves for abutting the collar strap; Around the tube is mounted the bottom bracket abutment rim which is put in Stroebe. Place junction necessarily sealed with temperature-resistant sealant. Around the pipe laying of the profile sheet by the standard procedure; On top of the roof covering is fixed upper limit abutment. Its junction with the pipe also need to be sealed. If a round tube, it is necessary to use a special member and communicating corresponding diameter, which fits over the pipe. Mounting the ridge plates: Put on the joint rays ridge bar; Sheet under the strap sealing tape; Fix ridge bar screws; Installation of additional elements. Once the roof is made of corrugated board, perform the following actions will be mounted: Along the perimeter of the eaves secure the screws wind braces; Then fix the drainage system and other additional elements of the roof, if any. Tint sheeting. Areas in which during installation damage the protective coating, it is necessary to tint. To do this, use polymer paint in the can. You can also use a special repair enamel and metal sheeting, although its price will be slightly higher.

In this installation of the roof is completed.

## A few important rules and recommendations

Finally, to share with you some important rules and tips that will help to cover the roof floorings without too much difficulty:

• Work in calm weather. Decking is lightweight, so in the wind sheet is hard to keep even two people;

Two lags significantly simplify the process of raising the profile sheets to the roof

• Gently lift the sheets. To lift the sheeting to the roof, set two boards or two boards on which the decking can slide on rails. In this case the reduced the likelihood that you drop the material;
• Carefully navigate through the roof covering. Use soft shoes, and try when traveling on the roof of the tread on the bottom of the wave;

The screws should be arranged in a staggered manner

• Properly install the screws. Clamps are screwed into the bottom of the wave, except in places compound sheets to each other.

On the edge of the screws must be screwed into each wave. Further, they are installed in a staggered manner over a wave. Vertical position them through the crates step.

Try to screw positioned exactly perpendicular to the crate;

In the process of cutting corrugated grinder melted polymeric coating - this reduces the life of the material

• Properly cut material. For these purposes can be used for metal cutting shears, jigsaw or hacksaw. But grinder to cut the prohibited lists, as it damages the protective coating.

To increase durability of the material sheet sections must paint.

Another important point - it is a cross-Lap, which, as I mentioned above, depends on the angle of slope of the ramp:

• Up to 15 degrees - 20 cm;
• In the range of 20-30 degrees - 15 cm;
• More than 30 cm - 10-15 cm.

Here, actually, and all the information on how to properly cover the roof floorings with their hands, which I wanted to share with you.
