 Features of the profiled sheet as a roofing material: characterize and install

There are a large number of modern roofing materials, each of which has certain advantages and disadvantages. One of them is a profiled sheet, which combines high strength properties and an affordable price. In addition, you can cover the roof with corrugated board with your own hands.

Roofing profiled sheet: technical characteristics

The profiled sheet has special technical characteristics that make this roofing material popular and durable.

Advantages and disadvantages, fire resistance limit

Profiled sheeting is a multilayer composite material based on a steel sheet with a thickness of 0.4 to 1.2 mm. The number of layers depends on the manufacturer and the type of material and can be from 3 to 10. This structure makes the coating as strong as possible, but does not make it heavier.

Roofing profiled sheet consists of several layers, which provide high strength and waterproofing properties, as well as a wide variety of color shades

Regardless of how many layers are present in the sheet, the main ones are:

  • cold rolled steel sheet;
  • galvanized coating, which is usually located on both sides of the steel sheet.

Additionally, the sheet can be covered with:

  • protective paint;
  • anti-corrosion layer;
  • primer;
  • chrome plated;
  • polyester or other decorative coatings.

The number of layers directly affects the manufacturer's warranty period. The more there are, the more and the guarantee. This is due to the fact that each layer has its own function, which protects the steel sheet from the negative influence of external factors.

Depending on the type and quality of the roofing sheeting, the number of layers in its structure can range from 3 to 10

When talking about the fire resistance of a profiled sheet, you need to take into account the type of other materials of the roofing cake. By itself, the corrugated board can be considered a fire-resistant material, but complete safety can be guaranteed only if the insulation and all other insulating coatings have the same properties.

The professional sheet has undeniable advantages. The main ones are:

  • long service life (up to 50 years);
  • light weight;
  • low price;
  • resistance to temperature extremes;
  • the possibility of self-assembly;
  • high bending strength.

This material also has one rather significant drawback - the profiled sheet does not absorb noise well, which means that when arranging the roof, you will need good sound insulation, which increases the cost of arranging the roof.

Wave height

The wave height depends on the type of profiled sheet, since it is the main characteristic that distinguishes its modifications from each other. The material intended for the arrangement of the roof usually has a high corrugation. Roofing corrugated board has a wave height of 35–44 mm.

Sheet dimensions

For the roof, a special roofing profiled sheet is most often used, which is marked C-44 and HC-35. These models have some size differences.

NS-35 professional sheet is characterized by increased strength and high wave, therefore it is often used as a roofing material

The S-44 profiled sheet has a useful width of 1000 mm and a wave height of 44 mm, as well as additional stiffening ribs, which increase the strength of the material, and therefore ensure a longer service life. This grade is used for the installation of roofs of metal buildings, panel structures or frame structures with a lathing pitch from 500 to 100 mm, depending on the steepness of the slopes.

Profiled sheeting with the NS-35 marking refers to the materials of the supporting-wall type. It is often used to equip the roofs of low-rise country houses. The required pitch of the lathing is 500 mm with a slope of up to 15o and 1000 mm for steeper roofs. The standard sheet has the following dimensions:

  • nominal width - 1006 mm;
  • useful width - 1000 mm;
  • profile height - 35 mm;
  • thickness - 0.5–0.8 mm.

Sheet thickness

The thickness of the profiled sheet largely depends on its type. To cover the roof, the following are usually used:

  • bearing sheets 0.55–0.9 mm thick. This is a rather heavy material - a mass of 1 m2 can be 7.4-11.1 kg, which means there are special requirements for the device of the rafter system;
  • specialized roofing sheets have a thickness of 0.55–0.7 mm and a weight of 6.3–8.2 kg.

Roofing sheeting colors

The covering of the profiled sheet directly affects its service life, which can vary from 5 to 50 years, provided that the roof is properly installed and maintained. The profiled sheet is painted in all basic colors according to the RAL catalog, so it can always be matched to the existing requirements for the overall design of a suburban area.

Roofing profiled sheet is painted in all basic colors according to the international RAL catalog

Typically used as a polymer coating:

  • polyester, the color of which varies from shades of ivory to signal black (if desired, even a white profiled sheet can be ordered from some manufacturers);

    The color range of polyester-coated profiled sheet is the widest - from white to signal black

  • plastisol, which is applied in a rather thin layer and is characterized by a slightly limited color range - usually green, shades of red, blue and gray;
  • pural - most often it has several primary colors that do not differ in great brightness.

Service life of roof sheeting

The service life of a profiled sheet depends on many parameters:

  1. Decorative coating. Zinc is most often used, which is quite volatile, which makes the corrugated board not very durable. The addition of aluminum to zinc increases the service life of the corrugated board up to 40 years. Coating the surface of the sheets with polymeric materials will allow the use of a profiled sheet roof for at least 50 years.
  2. Climatic conditions. Not every type of profiled sheet is able to withstand extreme conditions, for example, constant sun or sudden changes in temperature. A special type of material must also be used in the case when the area is characterized by a large amount of aggressive atmospheric precipitation, for example, hail.
  3. Loads. It is very important to correctly calculate the upcoming loads, based on the results of which, select the required material thickness. That is why it is not recommended to use wall material for roofing that is not able to withstand intense exposure.
  4. Operating conditions. A roof made of corrugated board requires careful maintenance. It is recommended to remove snow and debris in a timely manner, and do not use aggressive substances, abrasive agents and metal brushes to clean the surface.

Types and marking of corrugated board

In addition to the distribution of the profiled sheet by size, the presence of stiffening ribs and the height of the corrugation, there is another classification - according to the type of base material and decorative coating.

Colored

Painted profiled sheet is used if the aesthetic component is important for the roof, but at the same time the budget for repairs is sharply limited. As a decorative coating, various paints and varnishes are used, which are applied to a primed galvanized surface. These compounds create a film on the surface of the sheet that is resistant to external influences, due to which the sheet receives maximum protection against corrosion.

Painted profiled sheet has the longest service life due to a durable film, which is formed on the surface of the sheet by decorative dusting

There are options for painted profiled sheet that mimic various materials. Wood imitation is very popular.

Galvanized

The galvanized material is based on a steel sheet, which is coated with zinc on both sides. Density of application is usually 275 g / m22, while the thickness of the resulting coating is not less than 90 microns. This information is spelled out in the German state standard, which means that the material is completely safe for human health and the environment. The service life of galvanized material does not exceed five years, and the less the thickness of the coating, the shorter the service life of the profiled sheet. This is due to the fact that zinc has a high volatility, which means that its smaller layer will be depleted faster, and an untreated steel sheet will remain on the roof, which will quickly collapse due to corrosion.

Sometimes the profiled sheet is coated with a mixture of zinc and aluminum, which can significantly increase the life of the material, since aluminum provides much more effective protection.

Zinc is a volatile material, therefore galvanized steel sheet has a limited service life

Plastic

The plastic profiled sheet resembles an ordinary steel sheet only in shape, since it does not have a metal layer at the base. Most often it is used when arranging greenhouses or canopies. The advantages of this material are obvious:

  • moisture resistance;
  • small weight;
  • good heat and sound insulation properties;
  • the possibility of processing without the use of special equipment;
  • suitability for use over a wide temperature range.

Plastic profiled sheet can be either homogeneous, that is, consist exclusively of PVC, or reinforced with fiberglass, that is, reinforced.

Plastic profiled sheet does not have the same bearing capacity as metal, but to increase its strength, it is sometimes reinforced with fiberglass

This material can be sold both in sheets and in rolls. This allows you to design a roof of absolutely any shape and size, and also greatly facilitates transportation.

Transparent

The transparent profiled sheet is, in fact, polycarbonate, but it has a wavy surface typical of profiled sheet. This solution has undeniable advantages:

  • does not beat;
  • does not break;
  • has a low weight;
  • easy to assemble;
  • withstands significant loads, but in an area with a large amount of precipitation in winter, it is not recommended to use this coating;
  • can be operated in a wide temperature range;
  • well resistant to ultraviolet radiation.

The service life of the material is about 10 years.

Transparent profiled sheet has a higher load-bearing capacity than cellular polycarbonate

Marking

The marking of corrugated board is based on the type of material, in particular, on the purpose of its use. At the moment, there are three types of corrugated board, each of which has its own marking:

  1. Wall. Marking begins with the letter "C" (C10, C21, C8). Designed for exterior wall decoration and fences. For arranging roofs, it is usually not used, since the sheet is rather thin and is not able to withstand atmospheric phenomena to the required extent.
  2. Roofing. It is marked C44 and HC35. This material is characterized by the presence of additional stiffening ribs and a higher wave. The last parameter may vary depending on the purpose of the building (for example, for a residential building and a utility block, it is recommended to use corrugated board with different wave heights).
  3. Carrier. It is marked H60, H75, H114 and has the highest level of strength and reliability. Such properties are possible due to the large thickness and height of the corrugation (more than 44 mm). The load-bearing corrugated board can be used not only for arranging the roof, but also for permanent formwork and load-bearing floors.

The main marking of the profiled sheet contains information about its type and wave height

After the main symbols in the marking of the corrugated board, additional information may be indicated:

  • sheet thickness;
  • useful width;
  • maximum length.

All dimensions are in millimeters. For example, marking C18-0.5-750-11000 denotes a wall material 0.5 mm thick with a corrugation height of 18 mm, a working width of 750 mm and a maximum possible sheet length of 11 m.

How to choose a corrugated board for the roof

When buying material for a roof, you need to pay attention to:

  1. Appearance. The surface of the profiled sheet should be perfectly flat, in particular, there should not be even the slightest roughness, cracks and other damage. When inspecting the material, it is recommended to bend it. With a slight pressure, the material should return to its original state, with a stronger one, it should keep its shape.
  2. Availability of a certificate. It is recommended to purchase roofing only from trusted sellers who are able to provide you with all the documents.
  3. Useful length of sheets. It is better to choose a material the length of which corresponds to the size of the slope in order to minimize the number of horizontal joints and increase the degree of waterproofing. To calculate the length of the sheet, you need to add 50 cm to the overhang device to the value of the slope length.
  4. Decorative coating. A long service life of the roof is possible provided that a profiled sheet with a polymer coating is used, since it is this that is able to reliably protect the steel sheet.

Components for corrugated board

To equip a reliable roof, you must use components that are specially designed directly for working with a profiled sheet.

  1. Additional elements: ridge, planks for various purposes, gutter, snow retainers. If desired, you can choose a coating that completely repeats the color scheme of the roofing material. For the reliable installation of the add-ons, you may additionally need a ridge seal, as well as a silicone sealant for sealing joints with roofing material.

    The color of the additional elements can be matched exactly to the tone of the main roofing

  2. Paint in cylinders. This tool will allow you to make small repairs in a short time, for example, to repair a scratch.
  3. Self-tapping screws for corrugated board. They must correspond to the type of material used for the roof arrangement. This primarily concerns the length and diameter. For the profiled sheet, hardware with a diameter of 4, 8, 5.5 and 6.3 mm is most often used. The length of the self-tapping screws must be at least 19 mm. To calculate the number of fasteners, it is recommended to perform the layout of the profiled sheet on the roof, and then indicate the attachment points in the drawing. It is necessary to place the screws through one wave on the intermediate supports and in each wave on the extreme supports. Additional fasteners are used to fix the sheets together. After that, you need to multiply the number of sheet attachment points by the number of sheets. Typically, the average consumption of self-tapping screws is 6-9 pieces per 1 m2.

    The roofing screw must be screwed in strictly perpendicularly, without overtightening or loosening over the required attachment point

Roofing device made of corrugated board

The reliability of the roofing from the profiled sheet depends not only on the choice of high-quality material, but also on ensuring the correct structure of the roofing cake. In the case of a profiled sheet, the sequence of layers from the inside to the outside should be as follows:

  • vapor barrier - this layer prevents warm and wet steam from inside the room to get to the insulation, since when they come into contact, the operational properties of the latter are lost;
  • thermal insulation - you need to lay the insulation perpendicular to the direction of the profiled sheets;
  • waterproofing - you can use a specialized film, bituminous mastic and other similar materials. Roll coverings are laid with a slight sag (up to 20 mm) parallel to the cornice. The overlap between the canvases at the joints is 10-15 cm.

When arranging a roof for a non-residential cold attic, insulation is not laid in the space between the rafters

To ensure reliable fastening of the profiled sheet, it is necessary to mount a longitudinal crate, which is packed along the counter-lattice bars located along the rafters and increasing the ventilation space to prevent the accumulation of condensate. Sheathing can be made from:

  • bar 50 * 50 mm;
  • boards 32 * 10 mm;
  • plywood 10 mm, moisture resistant.

The higher the angle of inclination of the slopes, the larger the sheathing step can be. To equip a roof with a slope of less than 12 degrees, it must be solid. The optimal lathing pitch on steeper slopes is 50 cm.

Experts with many years of experience in the field of roof construction recommend laying a diffusion film over the sheathing.

Installation rules

To equip a roof from a profiled sheet, it is very important to correctly calculate the angle of inclination. This parameter affects the size of the overlap:

  • when the roof slopes from 12 to 15 degrees, the overlap of the sheets of material should be at least 20 cm;
  • when tilted from 15 to 30 degrees, it can be from 15 to 20 cm;
  • at an inclination of more than 30 degrees, an overlap of 10-15 cm will be sufficient.

For arranging a roof with a slope of less than 12o an additional layer of waterproofing is required and the use of silicone sealant to seal the gaps between the corrugated sheets.

The size of the overlap when laying the corrugated board is determined by the slope of the roof

The installation process itself is as follows:

  1. Preparatory work. At this stage, the material is cut and lifted to the roof. It is possible to cut the profiled sheet only on a flat plane, for this it is recommended to use a special tool. It is strictly forbidden to do this with a grinder, since there is a high risk of damage to the protective decorative coating, due to which the service life of the material can be significantly reduced... It is best to use an electric tool such as a drill. If you can't find it, then metal scissors or a hacksaw with fine teeth will do. You can lift profiled sheets using a lag. They need to be installed in such a way that one edge rests against the ground, and the other against the eaves of the roof.

    It is better to lift the sheets along two inclined logs, set at a distance of the width of the sheet

  2. Fastening of corrugated board. After all the preparatory work has been carried out, you can proceed directly to fastening the material to the crate. It is recommended to start installation from the ends. Use hexagonal self-tapping screws with a length of about 80 mm (the exact length depends on the type of material and is calculated according to the formula l = l1+ h + l2, where l1 and l2 Is the length of the profile thread and the thickness of the washer together with the seal, and h is the height of the corrugation). It is necessary to fasten the sheets at the bottom of the wave, and at the overlap and ridge part - at the top.

    Laying sheets of corrugated board begins from the end of the roof, and then gradually move along the eaves

  3. Installation of additional elements. You need to fasten the windshield and other strips using the same screws as the sheets themselves. The installation pitch of self-tapping screws depends on the type of additional element, for example, the wind and corner strip is fixed with a step of 200-300 mm.

After laying the material, it is necessary to ensure proper maintenance of the roof. Maintenance involves cleaning the surface from dirt, leaves and other foreign objects. Scratches are terrible only for polymer-coated sheets; they are not critical for galvanized material. To remove chips and scratches, you can use a special paint. In winter, it is recommended to remove snow from the roof using wooden or plastic scrapers or shovels.

How to properly fix the corrugated board on the roof: DIY step-by-step poultrying of fasteners, cutting, installation on self-tapping screws, tips (Photo & Video) + Reviews

Profiled metal rolling is perhaps the most frequently used roofing material in recent years. This is due not only to its high strength and wear resistance, but also to its relatively low price. If you have never encountered it before and do not know how to fix corrugated board on the roof, carefully study this article.


Advantages and disadvantages

If you are going to equip a roof, corrugated board is a material that, when used as a roof covering, allows you to get both some advantages and disadvantages. The advantages of such coatings are as follows:

  • Affordable cost is the main advantage.
  • You can install the material yourself, since the technology is quite simple.
  • Also, the advantages of this material are associated with its high resistance to any weathering.
  • If the protective covering of the corrugated board is not damaged, then the product is reliably protected from corrosion.
  • The light weight of the sheet facilitates its installation. You do not need any lifting equipment for this.
  • The service life of such a roof of a house can be up to half a century.
  • The material is fireproof and non-toxic.
  • The professional sheet can be used to equip a roof of any configuration with slopes of any slope (even on a flat roof).
  • Thanks to the corrugation, you can set the direction of the flow of water flowing down from the roof during a downpour and melting snow.
  • Large selection of colors. Aesthetic appeal.

Despite the numerous advantages, corrugated roofing has its disadvantages:

  • As the reviews of the owners of such roofing coverings say, there is a lot of noise from such material during rain and hail. To eliminate it, it is recommended to use not a sparse crate, but a solid one of OSB or moisture-resistant plywood.
  • Since condensation forms on the surface of the coating, it is necessary to make a thorough vapor barrier and protection from moisture.
  • The profiled sheet can accumulate static electricity, therefore, such a roof needs to be grounded.
  • Corrosion spreads in the holes in the coating for the installation of fasteners and along the cutting lines. To protect yourself from it, you need to cover these places with special paints and varnishes.

Which corrugated board is better for the roof

Profiled metal sheet, in a simple way, corrugated board is a roofing material known for a long time. But the roofing segment is only a small part in which this sheet material is used. Currently, manufacturers offer several types of corrugated board, which differ from each other in purpose. Accordingly, their markings are different. What does the modern construction market offer?

There are three types of profiled sheets on the market today:

  • "N" - carrier
  • "C" - wall
  • "NS" is universal.

The first type can be used to cover roof structures, for the construction of floors. The second is used for the construction of fences, however, it can often be seen as the roof of extensions, awnings and canopies. The third, as the name implies, can be installed everywhere without restrictions.

If the builders are faced with the question of which corrugated board to choose for covering the roof, then it becomes clear that models "H" and "NS" are acceptable options. But there are other selection criteria that must be paid attention to.

Types of roofing sheeting

Choosing corrugated board by size is the most correct approach. But let's start with the fact that this profiled material is made from galvanized sheet by cold rolling. The galvanized layer itself is already protective. And more recently, it was this gray shiny color that flaunted on the roofs of many buildings, mainly for industrial purposes. Private developers mainly used corrugated board as a protective material.

Changes have been made to production today. Manufacturers began to think about how to increase the service life of a corrugated roof. There are many options offered, here are just a few of them:

  • Aluminum coated corrugated board, marked with "A" marking.
  • With alumosilicon coating - "AK". A very durable material that can withstand severe negative operating conditions for a long time.
  • With aluzinc coating - "AC". Not the best material because it only contains 4% aluminum.
  • Let us remind once again about the zinc layer, which is applied to the metal sheet by an electrolytic process.
  • Painted corrugated board. The paint is applied by powder coating. An excellent option for the roof, it serves for a long time, does not create problems during operation.

The only condition during transportation, unloading and loading operations and during the operation of the painted type is careful attention to the surface of the corrugated board. The paint must not be ripped off, the metal must not be allowed to scrape or rub. This reduces the performance of the sheets, and hence the roof.

Polymer coated corrugated board. This type is the best in terms of long-term service. True, he is also the most expensive. But if the question is which profiled sheet is better, then it is worth giving preference to him.

I would like to dwell more thoroughly on zinc protection, because it is sheets of this type that are most often used by private developers. And the whole thing, as it turns out, is in the price. In addition, they are the basis for a large number of types of corrugated board.

So, galvanized sheet is presented on the market in three positions, the differences of which are the percentage of zinc per one square meter of the profiled plane.

  1. Business class, in which zinc is 126-220 g / m².
  2. Standard - 275 g / m².
  3. Premium - above 275 g / m².

It is clear that the higher the zinc content, the better, but the price is also higher.

By the way, GOST, according to which the corrugated board is produced, has a definite name: "Steel sheet bent profiles with trapezoidal corrugations". This name clearly defines the shape and raw material of the profiled sheet.

Dimensional criteria for corrugated board

Now we turn to the dimensional indicators, according to which it will be necessary to select the sheets for the roof. The first thing you need to pay attention to is the thickness of the sheet and its width. By the way, with regard to the width, there are two indicators: general and working. The thing is that the corrugated board overlaps with respect to adjacent sheets by one corrugation, so it will cover the roof area a little less, or rather, the width of one corrugation. Therefore, it is the working width that is indicated in the marking. For example, C21-1000, where “1000” is the width in millimeters.

With regard to thickness, the strength characteristics will be influenced by the thickness of the metal sheet. Protective coatings don't count. The standard range for this indicator is from 0.4 to 1.0 mm. it is clear that the thicker the corrugated board, the better its strength indicators. Of course, the thickness also affects the price. With an increase in this value, the cost of building materials also increases. There is another point here that reduces labor costs and makes the process of building a roof easier. There is no need to install frequent lathing under the corrugated board with a large thickness. Although experts believe that it is better to install the lathing than to buy expensive corrugated board.

There are two more dimensional indicators that answer the question of which corrugated board to choose. These are the dimensions of the corrugation, or rather, its height and width. By the way, the height of the corrugation is always present in the marking of the roofing material. For example, Н60-1000, where "60" is the height in millimeters. The range of the indicator varies between 15-130 mm.

This indicator is probably the main one of all sizes. It is he who is responsible for the strength of the entire sheet. And the higher the height of the corrugation, the greater the bearing capacity of the corrugated board. In addition to creating high strength characteristics, some models of the material, namely, H60 and H75, HC35, are equipped with stiffeners. They can be installed either on the edges of the wave, or at the base, as shown in the photo above.

The width of the wave, like its height, also affects the strength. But this dimensional indicator most often affects the choice of the roof slope. If the slope of the roof is less than 40 °, then it is better to install corrugated board with a high wave on it. And vice versa. That is, on steep roofs there is an opportunity to save money, because the higher the profile height, the more expensive the sheet. We add that the best option for flat roofs is corrugated board with a width of 20-60 mm.

Protective qualities

Let's return to the protective properties of corrugated board, and more specifically, to its painted and polymer versions. Let's start with paint. Today, painted corrugated board is the most demanded. And it's all about a huge palette from which you can choose a color that exactly matches the design of the house and landscape. And if designers and architects have the opportunity to include corrugated board in the project of the house, then they must do it.

It was already mentioned above that the paint is applied using a powder method, which guarantees the operation of a roof made of corrugated board for 15-25 years. Although practice has already proven that this type of roof lasts much longer.

But a polymer coating is better than paint - this is unambiguous. It should be noted that in the modern production of corrugated board with a polymer protective layer, different materials are used. There are four types of them (which is better):

  1. Polyester. It belongs to the inexpensive polymer coating options. Its thickness on a metal sheet is 25-35 microns. Such protection perfectly withstands natural stress, the color practically does not change during service. Such a corrugated board can have both a glossy and a matte surface.
  2. Plastisol. This polymer is based on polyvinyl chloride (PVC). An excellent protective layer that not only copes with atmospheric stress, but also resists mechanical stress. Its standard thickness is 200 microns.
  3. Pural is a polyurethane derivative. The thickness of the applied layer is 50 microns, but at the same time it can withstand high temperature operating conditions. For example, 150 ° is not the highest limit for a material. On the roof, on which the corrugated board with a pural coating is installed, you can safely walk in shoes, and at the same time the material does not tear, does not bend, there are no dents, cracks or other flaws on it.
  4. PVDF. This is a completely unique and new polymer compound, consisting of polyvinyl chloride (80%) and acrylic (20%). Application thickness - 27 microns. With such a small thickness, polymer symbiosis will give shape to all other materials. Profiled sheeting with such a coating is recommended for use in regions with an aggressive environment. For example, in cities with a high degree of gas and smoke pollution, on the coast of the seas and oceans, where the salty wind makes almost all building materials unusable in a couple of years. So experts believe that such a decking will last forever.

Conclusion on the topic

Of course, everything written above is easy to read. In practice, much may be inaccessible, and it’s not so easy to define everything visually. Therefore, to alleviate the situation, it is recommended to demand from the suppliers of corrugated board (hardware store, roof installation company) a quality certificate for the goods received.

It usually indicates the grade of the material, by which you can read the dimensional values ​​of the sheet. The document will necessarily spell out about the protective layers, what they are made of, what color, and so on. Even if it is difficult for you, the main indicator may be the price of the product. In this regard, the more expensive, the better the quality is likely to be true.After all, tough competition in the construction market does not allow suppliers to sell expensive goods.

Although it should be noted that in all the variety of types and types of corrugated board, there is always an opportunity to find high quality profiled sheets at reasonable prices on the building materials market. Therefore, before choosing a corrugated board for the roof, you need to understand all its characteristics, where the dimensions and markings can immediately tell which one is right for you and your home.


Sheathing type

After installing the rafter system, laying waterproofing and lathing, they begin to fasten the profiled sheets. For the installation of the lathing, you will need to purchase a beam with a width of 100-150 mm. With a small rafter pitch of 60-80 cm, a 25 mm bar is enough. If the distance between them is more than a meter, a thick beam of 50x50 cm is used for the lathing.

If the rafters are spaced 80-100 cm apart, it is enough to purchase a 32 mm beam. For fastening the waterproofing, a 4-5 cm counter-rack is used.

When choosing a step, the battens are guided by the thickness of the metal, the height of the corrugation and the angle of inclination of the roof. Sheets with a small corrugation height of up to 10 mm are laid only on a solid crate. Such material is used mainly for roofing sheds and other utility rooms. A solid lathing will also be needed when laying material on a roof that has a slight slope of up to 15 °.

Profiled sheeting C21 or MP-20R with a thickness of 0.5-0.7 mm is mounted on a crate with a pitch of 30 cm. If the angle of inclination of the roof is more than 15 °, a distance between the bars of 60 cm is sufficient.For NS-15 corrugated board, this indicator is 50 and 100 cm, respectively, depending on the angle of inclination.

Wall corrugated board: how to choose the right one and what to look for?

If you decide to sheathe the outer walls of the house, then you should choose the corrugated board of the C21, C20, C18 brands. The higher the number after C, the greater the strength of the material, so choose a grade based on the purpose of use.

When choosing wall sheeting, pay attention to:

  • the width of the grooves on the sheets. The wider the width, the higher the overall stiffness of the cladding. The presence of grooves also ensures that water flows down unhindered during rain and prevents water from entering the structure.
  • weight of sheets. On facades made with the use of light and fragile building materials, professional sheets of a small mass should be installed, for powerful buildings, you can purchase heavier products
  • coating quality. The higher it is, the longer the cladding will stand without rust and cracks.

↑ Piece roofing materials

↑ Beautiful, spectacular, but expensive and heavy - ceramic tiles

Roofing is one of the oldest roofing materials. For the production of tiles, clay is fired at a temperature of thousands of degrees. After that, it has hardness and strength, acquiring a brownish color with a red tint. Some types of shingles are glazed before firing to increase their water repellency. Usually finished tiles have the same parameters of 30 cm in width and length, and weigh from 2 kg.

Clay tiles have several types:

  • tape groove
  • grooved
  • stamped groove
  • single wave
  • two-wave
  • ordinary ceramic tiles.

Installation. When laying tiles on the roof, the slope of the roof is not less than 25 and not more than 60 degrees. When the slope is less than 22 degrees, then by all means provide for good ventilation and a layer of waterproofing. If the slope exceeds 60 degrees, then more nails or screws will be required for fastening.

Individual elements are connected with special locks, they are placed with an overlap: the upper tile is superimposed on the lower one. When finished, the roof resembles solid scales. The products are fastened to the crate with nails through special holes.

Where is it used? Ceramic tiles are used to cover roofs in wooden, brick, stone houses. The number of storeys does not matter.

Durability and cost. It is possible to operate such a roof without repair for 150 years. But the price for 1 m 2 ranges from $ 20 to $ 50.

  • economical maintenance - you need to clean the gutters with valleys once a year
  • good noise insulation
  • corrosion resistance
  • incombustibility
  • frost resistance
  • variety of profiles and tones
  • aesthetic appearance
  • the tile roof is porous, it “breathes”, evaporating moisture.

Disadvantages of ceramic tiles:

  • heavy roof weight - thicker or more frequent rafters will be required
  • it is problematic to cover a complex shape - additional insulation, fasteners, lathing are needed
  • fragility of material
  • high price.

↑ Sand-cement tile

Roofing piece covering is made from a solution, the components of which are cement and sand. The ingredients of the tiles are not fired, but pressed under pressure. The different color is obtained thanks to iron oxides, which make these tiles similar to ceramic. Glaze or tiles without any coating is applied on top. The surface is made smooth or with a profile convex pattern. The weight of 1 m 2 of the roof reaches 35-40 kg.

Installation. Sand-cement tiles are laid with an optimal slope of 20 to 60 degrees. The material is mounted to the crate in rows, through special holes on the tiles. When laying, make a "bandage", which is equal to 1/2 the width of the tile, shifting the row relative to the adjacent row. A board with a section of 5x15 cm is used on the rafters. The step between the rafters is from 60 to 90 cm. When installing this tile, a layer of waterproofing is used.

Where is it used? This roof covering is used in houses of different storeys and materials.

Durability and cost. The manufacturer gives a 30-year warranty for sand-cement tiles. In comparison with clay, this coating will be cheaper for the developer, since the price for 1 m 2 is from $ 10 to $ 20. And the appearance of the tiles is practically the same.

  • resistance to chemical aggression
  • not exposed to the sun
  • frost resistance (the manufacturer guarantees 1000 freezing cycles).

  • if compared with ceramic tiles, then a large thickness: not less than a centimeter
  • during careless transportation, you can lose up to 1/10 of the material
  • high price.

↑ Rare elite, but incredibly stylish covering - slate roof

When reviewing the roofing materials that developers most often use, we will also consider slate roofing. Albeit rarely, but this material is also used. True, only if financial resources are available. Nature itself produces this beautiful material using the forces of heating and pressure.

Slate roofs can be seen on ancient castles in Europe. In Russia, you can buy slate tiles, they are made by hand to order. The tiles are 4 mm thick, 20 or 60 centimeters long, 15 or 30 centimeters wide, and weigh 1 m 2 to 25 kg.

Installation. It is permissible to lay slate tiles on the roof with a slope of 25 degrees. The lathing is erected from boards with a section of 4x6 cm. The distance between the rafters is determined by dividing the length of the tile by "2", the resulting value is slightly reduced. For fixing galvanized or copper nails are used with a length of 9 or 10 cm. Two nails are required for one tile, for installation from the edge and with a slope of more than 40 degrees - three nails.

Durability and cost. The service life of a slate roof is from 100 to 200 years (but only with a properly equipped base). The price for 1 m 2 of material varies from $ 65 to $ 100.

Advantages of slate coating:

  • huge service life
  • exclusivity, great appearance
  • color fastness of the material, protection against ultraviolet radiation
  • frost resistance, water resistance, fire safety.

Disadvantages of slate roofing:

  • very high cost.

This was an overview of existing types of roofing. As you can see, each of the material has its own "but" - there is no perfect coating.

Therefore, choose a roofing material in accordance with your capabilities and requests.
