The roof of corrugated board: all you need to know about installation

As mounted roof of corrugated board? Is it possible to qualitatively cover the roof without attracting roofers? Below, I'll detail how to do it, and step by step instructions visually confirm my words.

From the metal material is characterized by a form of the profile.

A few words about the choice of corrugated board

Stamps sheeting. Keep in mind that not every professional flooring can be installed on the roof as possible. Below are the brands that are suitable for these purposes:

• C8. Wave of corrugated board has a trapezoidal shape. Its height is 8 mm, and width - 52.5 mm.

For mounting the brand sheeting C8 must perform continuous purlin

You can use this mark only with a solid crate. Another requirement - the roof must have a large inclination angle, since sheet strength is low;

• C10. From this material a C8 wave height is different, which is 10 mm. to the roof of the requirements for their use also remain the same;
• C18. Profiled this mark is a sheet with a smooth surface and the wave height of 18 mm. To use it as a roofing material, it is necessary to make a crate with a step of not more than 40 cm. Furthermore, the angle of inclination of the roof must not exceed 25 degrees;

Profiled brands S21-44 can be used on the roof without any restrictions

• S21-44. Profiled this mark has a wave height of 21 mm. It is excellent for flooring roof without any special requirements regarding the crates or step gradient;

NS35 - the best choice for mounting on the roof

• NS35-45. Corrugated sheets of these stamps are considered to roofing. They are characterized by the presence of additional ribs severity and more attractive appearance. I recommend using a roof decking brands NS35-45.

Coating. Therefore, a material parameter is divided into the following types:

• Without cover. This steel sheet is the cheapest but at the same time, its service life is significantly lower than that of the coated sheeting.
  In addition, it has an unattractive appearance. Therefore, such a material makes sense to use only for the outbuildings.

The roof is made of corrugated board without the least durable polymer coating

• Polyester. This is the most cheap cover, so common in the sale more often. Polyester well resists corrosion and adverse environmental influences.
  Its disadvantage is the instability to mechanical damage - coating is easily scratched during transportation and installation. So do not forget that the sheets require careful attitude. In this case, roofing lasts at least 25 years;

Polyester - the cheapest polymer coating

• Puranas. It is a polymeric coating based on polyurethane with the addition of other components. Such a protective layer is more resistant to mechanical and chemical damage, thereby improves the durability of the roofing to 50 years.
  The disadvantages are higher cost, as well as a cover fading over time;

Plastisol has a peculiar texture

• Plastisol. The coating is made on the basis of PVC and plasticizers. Its advantages include good resistance to mechanical damage, and chemical attack.
  The main drawbacks - it is the instability to high temperatures and fading fast. Therefore, in the southern region of this roof covering should be abandoned;
• PVDF (PVDF). The coating contains 80% of polyvinyl, and 20% acrylic. PVDF most reliably protects the roofing material on all of the negative effects of non-motorized and good resists mechanical stress.

PVDF - very robust polymer coating

Therefore, the PVDF may be called the best polymer coating. Its only drawback - the high cost. But the roof of the so-coated profiled sheet will last at least 40-50 years.

Polyester Matte more durable than glossy, as applied thickly.

Here, perhaps, and all the main points that you need to know about choosing the trapezoidal sheet roofing.

mount technology

Installation sheeting to the roof comprises two main steps:

Mounting battens

Waterproofing of the roof sheathing and decking under performed as follows:

	Preparation of materials. At this stage, you will need: Reiki section not less than 20x30 mm; boards section of at least 50x30 mm; Sealing tape; Waterproofing membrane. Before installing the board and batten necessarily treat protective impregnation.
	Waterproofing: Lay the membrane across the rafters stripes slope upwards. Be sure to keep it as sagging between the rafters at the centimeter and a half; Secure the first strip to the rafters by means of staples. The bracket is 100 mm step along the rafters; When laying a second strip is required to provide an overlap of at least 20 cm. place, seal the joint with adhesive tape.
	Installation kontrobreshetki. Attach the top of the rafters waterproofing along the rail, using nails or screws. In order not to disturb the sealing of the roof, beneath the rail sealing tape.
	Mounting battens: First board batten align along the edge of the ramp and attach kontrobreshetke screws or nails. Keep in mind that the first and all subsequent planks should be taken out of the gable of 50-60 cm; From the first board back off the required distance (30 to 60 cm, depending on the angle of the roof - the higher it is, the less you can do crate), and parallel to fasten the second board. According to this scheme, lathing is done on all the slopes to the ridge; In places stingrays joint around pipes and observation windows make solid crate.
	Construction of overhang on the gables. Connect pro-beam gable boards edge to strengthen the structure.

During installation you can batten insulation of roof space. To do this, the inside of the crate nailed to the rafters, so it could put a heater. In the case of mineral wool, do not forget to put it on both sides of a vapor barrier.

In this installation of lathing completed.

Laying sheeting

The process of stacking corrugated board looks like this:

illustrations	Description of work
	Preparation of materials. In addition to the corrugated board for mounting the roof, you will need: Self-tapping screws with sealing gaskets. Matched the color of the roof covering; Sealing tape. Individually matched to the type of profile. Additional elements. These include the ridge and eaves strips, valley, abutting strips and so on.
	Installation of wind strips: Attach the eaves gutter brackets for increments of 50-60 cm; Install eaves lath along the eaves as shown in the photo example.
	Laying the first sheet. Mounting profile sheets to the roof starts with the bottom corner, no matter the left or right. Work is carried out as follows: Place the sheet so that it is hung from battens 40 cm; Sheet aligned with the edge of the ramp; Lock screws sheet.
	Mounting the second sheet: The second steel sheet is positioned so that the edges lie on each other. The width of the overlap should be at the same wavelength; Align the second edge of the first sheet; The sheets with each other by screwing screws in oxen ridge; Secure the material to the sheathing screws. According to this arrangement, mounted entire first row of corrugated board. Last in a series of cut sheet width.
	Mounting of the second series of sheets. If the slope exceeds the length of roofing material, assembling the second series of sheets is as follows: At the upper edge of the sheets of the lower row, which is hidden under the top row of steel sheet, is required to lay the sealing tape; Lay a sheet of the second row. Transverse overlap should be 10-20 cm, depending on the angle of slope of the roof; Sheet aligned with the edge of the ramp; Fix the decking screws. According to this arrangement, mounted entire second series of trapezoidal sheet. The longitudinal seam is the same as in the first series of corrugated board installation.
	Installation of the valley. joint arrangement rays carried out as follows: Cut the length of the valley at the junction ramps and secure the screws; Spread profiled on both slopes. The last sheet is disposed so as to overlap the valley 10 cm. Between the strap and lay Endova sealing tape; Secure rays along top seam profiled sheet decorative upper valleys as shown.
	Arrangement passages of pipes. If the roof has chimney or ventilation pipe of square section, it is necessary to seal the joint as follows: Attach a bar abutment and apply opposite its rim marks on the tube; Proshtrobite perimeter tube according markup; Set your hands on the perimeter of the pipe abutting the bar by inserting a side in Stroebe. Place seam necessarily seal the heat-resistant sealant; Place the corrugated board around the pipe on a standard scheme; On top of corrugated fix the upper limit of contiguity. Stroebe pipe is not necessary for it, but the place treat joint sealant. Sealing round tubes is easier - used passage special element of suitable diameter, which fits over the pipe.
	Mounting the ridge plates: Cut the ridge strip along the length of the ridge; At the ends of the stub set; Place the ridge on a joint punk rays; For sealing ridge member, beneath the seal it; Fix the roof bar with screws, placing them through the wave corrugated board.
	Installation of additional elements: Close the ends of the sheeting, securing additional elements on the eaves screws; Install gutter system, placing pipe holders.
	Tint sheeting. After installation, a professional flooring and installation of additional elements of the roof should be inspected carefully. If you noticed on the surface of the roof covering the scratches, they should definitely paint. You can use a polymer ink in the cartridge.

Some of the recommendations and rules of installation

Finally check out some important rules and guidelines that will help you put quality roofing material:

• Work with trapezoidal sheet in calm weather. Sometimes, in the wind, even two or three people are not able to hold the sheet;

Set screws according to the scheme

• Correctly screw the screws:

1. The screws should be placed at the bottom of the wave. Exceptions are screws which connect the two sheets;
2. Along the eaves screw the screws in each wave;
3. Subsequent rows set staggered through wave;
4. With regard to the longitudinal arrangement of screws - install them through the crates step;
5. In the process of tightening the screws, make sure that they are included in the profiled strictly perpendicular. Distortions violate fixing leaks.

A common mistake is to beginners excessive tightening screws, whereby the deformed and damaged O-ring. Therefore, avoid excessive force when tightening the screws.

Cutting corrugated grinder reduces its lifetime

• Do not use the grinder for cutting sheets. In the process of cutting corrugated grinder melted polymeric coating. This reduces the life of the roofing material.
  Therefore, cutting of sheets should be carried out with a hacksaw, scissors, metal or jigsaw;
• Lift sheets using the lag. Put two long bar and tighten the sheets over them on the roof, like on rails. In this case, it decreases the likelihood that you drop leaf, and it will be damaged;

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

• Follow roofing robots in soft shoes. Shoes with hard soles may damage polymer coating. In addition, do not put on sheets of corrugated metal tool.

To in sections with time sheets did not appear rust, the ends need to paint.

Here, actually, and all the information on how to cover the roof of corrugated roofing sheets by hand.
