Flat roof from corrugated board

Corrugated board flat roofs are a useful and affordable option for a variety of building types, combining affordability and longevity. These flat designs offer a unique aesthetic and practical appeal that sets them apart from conventional sloped roofs, making them perfect for both residential and commercial buildings.

Corrugated board, which is typically made of fiberglass or metal panels with ridges and grooves, strengthens and protects the roof from UV rays, rain, and snow. Compared to heavier roofing options, this material’s lightweight design makes installation and maintenance simpler.

The versatility of corrugated board is a major benefit when selecting it for a flat roof. It can fit a variety of roof sizes and shapes as well as different architectural styles. It is a well-liked option for both professional builders and do-it-yourselfers because of its versatility.

Furthermore, corrugated board is a cost-effective substitute without sacrificing quality due to its low cost. It is a cost-effective option for people who want to improve the usability and aesthetic appeal of their property without going over their budget.

Advantages Cost-effective, lightweight, easy installation
Disadvantages Susceptible to rust, noise during rain, limited lifespan compared to other materials

Building a roof from a professional leather with a minimum slope

The selection of the angle is one of the most laborious steps in the corrugated board roof design process. Here, aesthetics don’t matter; what matters is how tall your roof is in relation to its overall area, which will determine how much usable space your attic has left, whether snow accumulation will be an issue, and whether wind will carry your roof into a powerful storm. However, this is not unusual! We’ll work it out, I think. What is the roof’s minimum slope, as determined by the profiled sheet? How to construct a roof with the least amount of slope!

Recommendations SNiP for a roof from a profiled sheet

Let us now examine official data. Therefore, any roof with a slope of at least 8 ° can be covered with corrugated board in accordance with SNiP, construction standards, and regulations. Precipitation will only be unable to enter the joints and screws in this manner. In this case, the crate’s step needs to be 40 cm.

However, the minimum inclination angle for the roofs of outbuildings and industrial buildings is 8 °, while the threshold for residential buildings is 10 °. The minimum threshold will be even higher if the roof can be divided into two or more layers. For this reason, contemporary construction firms only offer guarantees for their work if they cover a roof with a slope using at least 12 ° of corrugated board. However, a roof made of profiled sheeting can have a maximum angle of at least 70 °, if not more.

Thus, SNiP suggests that the best option for a profiled steel sheet used as roofing material is a 20° bias. But what should you do if you have to construct a nearly flat roof? For an arbor, an outbuilding, or a garage? Then just do as we say, and you won’t have any issues!

Degrees, interest and ratio

The roof has an 8 ° slope, meaning that a minimum value of 1: 7 can be achieved when installing corrugated board. Additionally, it’s important to carefully inspect the roof for ventilation once all work has been completed. Why do roofers use percentages and even coefficients in addition to degrees when calculating a corner? Everything is the same; the only things that differ are the design documents and the material ordering process. A table that we have prepared for you will assist you in determining what’s what:

Let’s now calculate it using construction terminology. Thus:

  • Flat roofs are called flat, the angle of inclination of which does not exceed 5 °.
  • Naughty those that are usually more than 20 °. Naturally, the pitched roofs are more waterproof, and therefore more popular in private construction.
  • Roofs with a small angle of inclination – up to 25 °. Here you can already equip the attic rooms, but without windows.
  • Cool – those that have a slope of more than 40 °. Cool allow you to equip a good residential attic that is not superfluous.
  • The more is the slope of the roof that falls on the interval of 45-60 °.
  • But ideal today is the angle of roof slope 38-45 °.

Therefore, the roof’s minimum corrugated board inclination is 8 °. This video master class explains in detail how these kinds of roofs are constructed:

The profiled sheet should already be at the bottom of the roof pie, overlapping, if you have to build a roof with an even lower inclination. The design tenet is only evolving.

Cons and pluses of the roof with a minimum slope

And now for the things you can anticipate from it going forward as well as the challenges you will face when building the minimum slope roof.

First, let’s enumerate the benefits. The following are the primary benefits of building such a roof:

  1. Smaller consumption of material.
  2. Lighter and safe roofing.
  3. The absence of a skate and problems associated with its sealing.

Consider this situation: the greater the horse’s height, or the greater the roof’s angle, the harder the roof is. Ultimately, the content will cover more. And the foundation and the house are under a lot of strain because of this. The load will be negligible in this instance.

We then moved on to obnoxious negatives. The minimum roof slope is problematic because it causes rainwater to drain into the roof pie much more slowly and find tiny gaps and crevices to leak through. The 12 ° angle serves as the threshold in this case, beyond which further sealing steps are not necessary. Consequently, the location of the overhead overlines will need to be compacted using special roofing sealants if you construct a roof that is more gently sloped, with a slope angle of less than 12 °.

The chosen angle of inclination will determine what kind of material you can use for the roof. Therefore, only a strong, high-corrugated corrugated board is appropriate for a flat roof or a roof with a slight slope. However, it is acceptable to cover a steeply sloping roof with both a wall and universal profile because there will be less pressure on the sheets now. To put it another way, the water does not linger in any way and the same snow slides easily.

The second is that there will be a rise in material consumption. There will need to be a fair amount of sheet overlap. Therefore, increasing the overlap of sheets will be required if you plan to build a roof with an angle of 12 to 14 degrees. If the angle is less, sealant will be required. Why is a slope of 15 to 30 degrees ideal for a corrugated board roof? This data is shown in a more thorough table here:

You will save a lot of money on roofing material even though installing steep roofs from profiled sheeting will require you to build fairly long rafters and leave more space between the bars. Since the corrugated board’s bearing capacity will now be less important than with gentle roofs, it can be purchased for less money with a smaller wave height.

Furthermore, a residential attic cannot be equipped to lower the house’s roof-based heat loss to 9% due to an inadequate angle of inclination.

And last, in order to build a roof with a small angle of inclination, a far more intricate rafter system that can support a substantial weight is needed. More subterranean elements are present at smaller inclination angles.

We are going to upset you a little bit now: even though we have considered all the benefits and drawbacks of a roof with a minimum angle and determined that 8 ° is the better value, it might not be possible to construct precisely such a solution. Instead, it won’t be risky! Why? Continue reading!

Wind and snow

Numerous preliminary data points actually affect the calculation of the corpus delicti’s roofing angle. These are first and foremost local climate characteristics that determine the value of your home. Therefore, learn ahead of time how high the snow usually gets on most winter days, how frequently it rains, how strong the wind is, and which way it blows:

After all, the slope of the roof of such a material as a professional is calculated not for aesthetic reasons, but just based on weather factors. So, the bias of the roofs of those houses that are located in areas with strong wind loads strive for a minimum value. In these areas, the so -called "sailing of the roof" is dangerous. You heard or saw how sometimes powerful polycarbonate greenhouses “walk” in the fields “walk” through the fields? But they were also not put on the ground without fastening. And now imagine possible consequences if you already literally tear off part of the roof in the literal meaning. Remember what is the most important drawback of corrugated board? "Sailing"!

These are SNiP’s requirements in relation to this. The slope angle needs to be made between 35 and 45 degrees for an average wind load and between 15 and 25 degrees for a strong wind. The profiled sheet’s roof’s angle of inclination is nearly the minimum to lessen wind resistance in the same location where strong winds are common. However, nearly flat roofs made of this material run the risk of being easily ripped, so in this instance, the total lack of steepness is also not better. Here’s a pretty amazing DVR recording of the wind ripping the soft roof right off the corrugated board:

Consequently, do not believe that the wind load is safer than snow. For instance, the average value in the Novgorod region, where the snow content is approximately 75 kg/m, is 23 kg/m.

Then it is not worth making all the roofs with flat? Not at all. Snow in Russia, as everyone knows, happens in winter. But such fragile at first glance snowflakes actually weigh a lot. For example, for a single -remarkable winter on a flat roof, so much snow can gather, as if a whole company would stand closely on it. No rafters can withstand this, and therefore, in areas with significant snow loads, the slope of the roof has to be done up to 45 ° – so that the snow does not linger. Then there is no need to strengthen the rafters – precipitation on such a basis will no longer be delayed at all. After all, snow slides easily only from steep roofs.

The parameters for your area are shown on the following map:

Fear: snow loads on rooftops in Yakutsk can occasionally exceed 550 kg per square meter. And already, this weighs half a ton! This explains why the houses in this area always have such tall, cool roofs. However, in the southern countries, straw can even be placed on top of them in a horizontal orientation.

You cannot even begin to imagine how much harder even a thin layer of snow is. Furthermore, snow stays on the roof longer than rain does. In fact, in some parts of Russia, snow can occasionally reach heights of over a meter. In this sense, a minimum bias is the worst of all.

Therefore, you must decide whether to make the roof’s angle from the corrugated board so small.

How to calculate the angle of inclination yourself?

Start by observing the types of roofs that your neighbors have. We refer to the location where you will be constructed. Typically, they have a nearly equal slope, which hurricanes have tested over centuries of suffering. Additionally, you can determine the precise inclination of the completed roof with an ordinary square as well as with specialized graphs and matrices.

Expert builders, for instance, use geometric formulas or devices like slopes to determine the roof’s slope. The outcome is expressed as a ratio or in degrees:

Or even more straightforward. Finding the hypotenuse and leg lengths is the first thing you need to do, as you probably recall from your geometry class in school. The roof’s straight hypotenuse slopes to the overlapse, which is an anti-icing cattle’s distance from the skate. The distance between the adjacent cattle and the cornice slope, located at the middle of the ceiling. And now, either with an engineering calculator or by using the trigonometric function:

The second method is equally common and accurate: we calculate the ratio of half the overlap’s width to the height of the ridge above the ceiling. Multiply by 100 after dividing the height by the building’s half width. Just!

Decide on your roof’s slope based on the following four main factors:

  1. Planned budget.
  2. Alleged snow loads.
  3. Average wind value.
  4. Need for a beneficial undercarbon space.

If, however, you still feel that you require a roof with a minimum angle, we will advise you on what steps to take and how to prevent construction errors.

Other important aspects of construction

The houses in areas with lots of sunshine and little precipitation tend to have roofs with reinforced rafters that meet the minimum required slope. Heat-insulating materials and a ventilated gap are included in the roof pie to lessen interior heating. If not, all that is left to do is make sure that water does not enter the house.

Defense against disclosures

When installing corrugated board on gentle roofs, make sure to use mastic and sealing ribbons for sheet overlaps and joints. Such a roof is additionally shielded from damage and leaks by unique membrane waterproofing materials. This is a typical pie made using this design: Sheathing follows rafters, insulation, waterproofing, and corrugated board.

Such a time still exists. For waterproofing, use a modern three-layer membrane if the roof’s slope is less than 10 degrees. This material is the only one that can keep moisture from entering the roofing pie.

Lastly, no matter how minimal the roof was in terms of slope, the drainage system will still need to be designed for it. Like snow, moisture lingers longer than most people think on such surfaces. Therefore, if the collection system is internal, plan a slope that goes towards the water intake; if it is external, plan a slope that goes towards the grooves.

Crate and Rafter System

The corrugated board fits on the crate, just like in regular projects, with a minimum bias, and is fastened with rubber gaskets. However, overlap already has steel rivets pinching it from 10 to 20 centimeters. It is advised that you create a two-wave overlap.

There is a correlation in which a wider overlap of sheets is required the lower the roof’s angle of inclination. Additionally, the smaller the material’s already effective area is:

  • Within 15-30 ° tilt overlap, do 15-20 cm.
  • But during the construction of a coolest roof, with an angle of 30 °, the overlap should be from 10 to 15 cm.
  • If the angle of inclination of the roof is already less than 14 °, then the sheets must be laid horizontally with an overlap 20 cm.
  • With a minimum angle of 8 ° tilt of the metal -profile roof, the joints between the sheets must be made double, carefully filling them with sealant so that water does not get inside.

When installing a conventional rafter system, the step should be reduced to 40 cm from 60 cm to 1 meter; however, if the roof slope is minimal, this step should be reduced to 40 cm. The snow buildup on the roof will be easier to transfer and the base will end up being stronger.

Additionally, a ventilated gap is necessary with slopes of the minimum value between the corrugated board and the rafters system; this is another way to reduce heat loss. More precisely, you must leave a space for ventilation that is at least 50 mm wide; the smaller the angle of inclination, the wider this gap must be.

This is a thorough master class that demonstrates how corrugated board is installed on a roof like this:

Keep up with technology and heed our advice, and everything will turn out fine!

As an alternative to many roofing materials, corporal roofs are generally quite good. A protective layer composed of materials akin to polystyrene offers dependable anti-corrosion shielding. The corrugated board has excellent safety settings, and you can choose the color of the roof. However, it is preferable to leave this roofing work to professionals; I myself lacked the courage and chose to look on from the side.

The climate, amount of precipitation, wind speed, and roofing should all be taken into consideration when choosing the slope. in order to prevent issues from arising after the procedure. Here, precise calculations are the only thing that can help; improvisation and creativity should be avoided. It was not necessary to search for the most waterproof material because I am in favor of maximum bias, which ensures that snow and rain do not remain on the roof for very long.

The design of a flat roof from corrugated board

Although pitched roofs are common in modern construction, flat roofs can also be quite appropriate in certain situations. They work well in two-story buildings without intended attic devices. Such roofs are also referred to as unrecking. Various materials are utilized for roofing. It is worthwhile to take note of the reasonably priced and attractive corrugated board.

Pros and cons of a flat roof

Even though the flat roof’s design is simpler than the pitched roof’s, it still has a very unique appearance. The benefits and drawbacks of this type of roof are as follows.

  1. Installation faster and easier. The arrangement of a flat roof is easier to perform, because due to the horizontal surface it is convenient to move along it.
  2. Less cost of materials. The design of a flat roof does not provide a complex rafter system. Therefore, its arrangement is carried out in a relatively short time, and the costs of materials are reduced.
  3. Original design – flat roofs from corrugated board are not so common.
  4. The site on the roof can be arranged as a recreation area, greenhouses or just a pleasant place for walking.
  5. On a flat roof, it is more convenient to install and maintain antennas, external blocks of air conditioning systems and the like.

One can observe the following drawback: snow and precipitation buildup on the roof’s plane. To stop this from having detrimental effects:

  • the surface is arranged with a small slope;
  • The roofing pie and the final coating (in particular, the installation of corrugated board) fit in accordance with the technology.

How the flat roof is covered

Actually, the flat roof overlap is set up using the same principles as other floor to floor arrangements. It should be remembered that during periods of intense rainfall, it will be exposed to high loads. Beams made of wood, metal, or reinforced concrete serve as the floor’s foundation.

The slope comes next. It is a layer of concrete that is at least 4 cm thick and allows for a roof slope of 5-7 degrees. This angle and the rainfall system allow excess water to be lowered, preventing leaks.

Features of the roof pie

The roofing pie is placed next to the corrugated board and the layer that provides the roof with the required slope. The order of material placement is the same as that of the pitched roof.

  1. Vapor barrier layer. It is laid to protect the insulation from water vapors rising from the living room. However, it performs another function. As a result of sharp temperature fluctuations on the street on the inside of the insulation, condensate may appear. A vapor barrier film will prevent it from entering the ceiling design. Polyethylene or polypropylene is usually used to arrange this layer.
  2. Thermal insulation layer. Most often, flat roofs are insulated with extruded polystyrene foam, mineral wool, polyurethane foam. It is important that thermal insulation material is resistant to compression, temperature fluctuations and static loads. No less important condition – fire resistance. For flat roofs from corrugated board, insulation in the form of plates, not roller materials are used. Put them in two layers. By operating indicators the best option – basalt cotton wool in mats.
  3. Waterproofing layer. This material completes the roofing cake for coating from corrugated board. Due to differences in the structure of the flat roof, membranes are not used here. Waterproofing is laid only to protect the sub -seal space from moisture. To move the air in the waterproofing layer, vanies are made, which contribute to ventilation and removal of moisture from the pore of the insulation.

One of the best materials for setting up a flat roof is corrugated board. The spaces between the waves are packed with non-combustible porous materials to stop blowing. Snow blocks must be kept away from the coating, though. It is advised to use corrugated board natural cleaning systems for this.

What are the varieties of a flat roof

Rarely seen flat or single-sided roofs for private construction. In general, unrequited corrugated board roofs are found in arbors, bathrooms, and multi-story buildings where pitched roof construction is just not feasible. In addition, designs for cottages featuring flat roofs appear incredibly unique. With careful space planning, even the absence of an attic can be an asset.

The different types of flat roofs are as follows.

  1. Operated flat roof without an attic, but with a platform equipped with above. To ensure a solid waterproofing layer, a concrete base of the roof is performed.
  2. Unexplosive roof with an attic without the upper platform. Such roofs are made without a hard foundation. Even if there was a leak, damage will only be in the attic.
  3. Traditional flat roof. With the help of a concrete layer, a slope is formed for water and snow. The waterproofing layer is located above thermal insulation.
  4. Inversion roof. It is suitable for any object, both residential and economic. The inversion roof is not subject to leaks, but has a complex device of a roof pie. A vapor barrier is laid on top of reinforced concrete, then 2 layers of mineral wool. The insulation is covered with screed, and waterproofing and a layer of corrugated board are already laid on top of it.

The advantages and arrangement of a single -toclock roof

Single-slotted roof devices are advised for small private homes, garages, bathrooms, and domestic buildings. There is only one surface to it. The accurate determination of the inclination angle is crucial in this situation. It’s between 10 and 20 degrees.

One benefit of a single-sided corrugated board roof is that snow removal from the roof is not a responsibility. You are able to equip the attic if it is tall enough. Next, you must install premium thermal insulation. However, you will be able to obtain an extra living space if you choose this option.

Construction of a single -sided roof

  1. Installation of rafters. Brusyev section and bias are chosen, focusing on the project. It is worth considering that the greater the slope of the single -sided roof, the easier it will withstand heavy snowfalls.
  2. Thermal insulation . If a residential attic is planned, the distance between the rafters is filled with insulation.
  3. Installation of the crate. This element of the construction of a single -to -shuttle roof will be subject to significant loads, so for its installation you need to take quality materials. As a rule, wooden bars with a section of 5 × 5 cm go to the crate. It should be located in such a way that the insulation and waterproofing film do not contact.

  1. Waterproofing. Polyethylene or polypropylene film is rolled perpendicular to rafters. The overlap between the layers leave up to 20 cm. During laying, move up from the bottom. All joints of the material are glued.
  2. Installation of corrugated board. Sheets on a single -sided roof are attached, moving from the bottom up. The initial row is laid taking into account the cornice overhang. For fastening, use screws in the color of a profiled sheet with rubber washers. The overlap along the sheet is 1-2 waves, the overlap between the rows across the profile is 20 cm.

One of the best options is to use corrugated board to coat a flat or single-slot roof. This material is long-lasting, attractive, and sturdy. It can be mounted without specialized building knowledge.

The usefulness, advantages, and installation issues of using corrugated board for flat roofs are examined in the article "Flat Roof from Corrugated Board." It talks about how corrugated board can be an affordable, long-lasting solution that works well in a variety of weather situations. The steps involved in installing and maintaining such roofs will be covered in detail in this article, with a focus on do-it-yourself methods and important elements that guarantee durability and weather resistance. It attempts to provide homeowners and do-it-yourselfers with clear insights for effective roofing solutions by guiding them through the selection, installation, and upkeep of a corrugated board flat roof.

Corresponding roof device: design and installation features

Recently, profiled sheets made of steel have been increasingly using the roofs, they successfully replaced the coating of a galvanized metal and won the trust of builders and homeowners. Corrugated board is used to build roofs in low -rise residential and production construction. This material is famous for its high bearing capacity, resistance to corrosion and temperature changes, as well as an affordable price. However, the main advantage of the profiled sheet is the simplicity and ease of installation, which allow you to perform the flooring of the roof with your own hands. The device of the roof from corrugated board has its own characteristics, without the knowledge of which you cannot achieve a qualitative result. In this article we will tell you what a roofing pie for coating consists of, and also how it is laid and fixed.

Characterization of the material

The modern material used to construct the roof is called corrugated board, and it is made of cold-rolled steel that has been thinly left. This coating’s manufacturing technique coats steel blanks with a zinc alloy and a polymer or paint layer to improve the products’ resistance to corrosion and impact. Following staining, the sheets were placed in a machine that used special rollers to press a trapezoidal or rectangular profile into them. The following are thought to be the profiled sheet’s benefits:

  • A light weight. The mass of 1 square meter of roofing coat from profiled steel is 8-17 kg, which is 2-3 times less than ceramic tiles or asbestos-cement slate weighs. Light weight reduces the load on the foundation, allowing you to save on the rafter frame of the roof.
  • Corrosion resistance. "Chronic disease" of roofing coatings made of metal is rust. But zinc and polymer or paintwork protect the steel from which corrugated board is made from contact with water, due to which the anti -corrosion properties of this material are increased.
  • Long life. The life of the roof coating from a profiled sheet, depending on the quality, price and compliance of the material technology, is 25-50 years, which significantly exceeds the operation of roofing material, ondulin and slate.
  • Large selection of colors. Polymer and paintwork allow you to paint corrugated board in any shades. The color scheme offered by manufacturers has hundreds of items, including the Metalik series.

Note: Depending on the thickness of the workpiece and the polymer or paint layer, the corrugated board can range in thickness from 0.45 to 1 mm. 646–1200 mm wide sheets are produced. The material’s profile rises with decreasing sheet width, increasing the material’s bearing capacity.

Roofing roof from corrugated board

A cold roof is a roof structure where the attic is not heated, thus the slopes’ thermal insulation is not included. This method is regarded as conventional, but it works incredibly well because the undercarbon room acts as an air layer that the roof and rafter frame need for ventilation. Generally speaking, houses, production buildings, and structures used only occasionally are built with cold-type roofs. In this instance, the roofing pattern consists of the following components:

  1. Rafter legs. Cold -type roofs for a roof from a profiled sheet are made of wooden boards with a cross section of 50×150 mm or metal. The maximum step between the rafter legs is 100 cm.
  2. Waterproofing material. On top of the rafter legs, with the help of a building stapler, the overlap with strips is fixed by waterproofing, which use films, diffuse membranes or ordinary roofing material. Waterproofing material is laid with a slight sagging to prevent gaps.
  3. Contact. The counterparty is made of wooden racks 2-3 cm thick, which is pinned along the rafters on the rafters on top of the waterproofing. It additionally fixes the waterproofing material and provides a ventilation gap between it and the corrugated board.
  4. Chatter. The crate is made from boards of 40×100 mm or bars 40×40 mm. The lattice and solid installation scheme is used. The greater the bearing capacity of the profiled sheet, the less often you can take a step between the elements.
  5. Roofing material. Sheets of corrugated board are laid on the crate, which are packed on each other in a horizontal and vertical direction to create a tight coating, and fixed with roofing self -tapping screws.

Crucial! The installation of a warm corrugated board roof involves installing a vapor barrier membrane from below the rafters and placing thermal insulation material, such as mineral wool, between the rafters. Furthermore, because roofing does not pass steam, it cannot be used as lining waterproofing for a heated roof.

Every roofing material has a recommended bias that verifies roofers’ experience and outlines the manufacturer’s instructions. Corrugated board should be installed on roofs with slopes between 8 and 9 degrees. This indicator is related to the coating’s application technique and form of release. Water will inevitably seep through the horizontal joints between the sheets on a sloped roof, which is not advised. This will result in leaks. The profiled sheet installation technology map is created based on the roof’s design:

  • If the angle of slope of the roof slopes is less than 8 degrees, then the overlap between the sheets of the corrugated board should be 200-250. To prevent leaks, all joints are treated with roofing sealant on a silicone basis. During the installation of low -acne roofs, the consumption of the material increases, which increases the cost of roofing work.
  • If the slope of the roof is 9-15 degrees, the overflows between the sheets of the corrugated board should be at least 200 mm, and the processing of joints by sealant is not a mandatory operation.
  • If the slope of the roof is 15-30 degrees, you can be reduced between sheets of roofing material to 150-200 mm, which corresponds to 1-2 waves.
  • If the slope angle exceeds 30 degrees, the overflows between the canvases make 100-150 mm, overlapping the sheets by 1 wave.

Crucial! In order to avoid coating deformation due to heavy snowfall and wind loads, a continuous crate made of chopped board or moisture-resistant plywood is constructed during the installation of low-acne roofs made of corrugated board. The greater the slope’s angle of inclination, the greater the space between the crate’s components.

Design requirements

The quality of the roofing material and adherence to installation technology determine the dependability and lifespan of a corrugated board roof. After 5-7 years, a roof that was not constructed in accordance with the guidelines for installing profiled steel will start to rot and flow. For the profiled sheet coating to function as a dependable shield against wind, cold, and moisture in the atmosphere, the roof’s design needs to adhere to the following specifications:

  1. Corrugated board is allowed to mount on roofs with a slope of 8-60 degrees. In this case, the angle of inclination of slopes is determined in accordance with the climatic conditions in the construction zone.
  2. The maximum step between the rafter legs for the installation of corrugated board is 1.5 m. This indicator depends on the bearing capacity of the material. If the roof belongs to a warm type, the rafters are located at a distance of 60 cm or 120 cm so that it is convenient to place thermal insulation material between them.
  3. To reduce the number of joints between the sheets, a material is used for the flooring of the roofing, the length of which corresponds to the length of the slopes.
  4. With a roof flooring from a profiled sheet, installation of a continuous or sparse crate is allowed. However, in places of joints of sheets, installation of snow retainers or elements of the drain, the crate is reinforced with additional boards.
  5. The instruction prescribes to use special roofing screws with a seal for fixing sheets. The neoprene washer is flattened during twisting, sealing the hole in the roofing material.

Skilled artisans observe that using shaped components for the skate’s equipment, yends, the pipe’s output, or the joints between the slopes, you can create a premium, sealed coating of profiled steel. In order to be undetectable after installation, they are also composed of steel and painted in the same tone as the corrugated board.

We study the roof device from corrugated board

There is an enormous assortment of sturdy roofing materials available in the current construction industry. They usually don’t require a special tool or level of expertise to install, making them easy to work with. Corrugated board is the material of choice for roofing. When one is familiar with the fundamental ideas and guidelines behind roof construction, it becomes effortless to construct a corrugated board roof on one’s own without the need for outside assistance. What first and foremost should you know?

The main rule is security

Regardless of the technique or materials utilized, installing a roof is a riskier task. Making a mistake can always happen; you could trip and fall or drop the tool on workers below. Use of safety belts or climbing equipment is always advised to avoid this. Since these are extra expenses, it is not necessary to purchase such equipment. It can be rented for a reasonable price; either way, the cost will be less than that of treating a broken limb.

You should fasten the entire tool to the belt or crate in order to safeguard the workers below.

It takes at least three persons to raise the corrugated board sheets on the roof. Three will take sheets on the roof, and two will serve sheets with lag. Try to raise a few sheets at a time and don’t rush. They normally fit together tightly when in a horizontal position, but when they are tilted at an angle, the upper sheet may slip and cause harm to the supply workers.

The device of the crate

The corrugated board roofing technology has unique properties. It is just like any other roof when it comes to the rafters being installed. However, the actual crate is a little bit different. The crate’s bar measures 25 cm for a single-sided roof and 50 cm for a gable roof. If the roof has a small angle, you will need to use plywood or boards to create a continuous crate. The arrangement of the crate’s neighboring leaves should prevent the joints from falling into any defects.

Wooden structures must be treated with an antiseptic and fire retardant after the crate is installed. You shouldn’t assume that the roof is fireproof at this point. This is untrue because the goal of fire processing is to increase the tree’s resistance to burning rather than to make it into a non-combustible substance. People may therefore be saved in the room because there will be more time before the roof collapses during the fire.

It’s crucial to remember to steam/waterproof the roof in order to prevent moisture from building up on the crate beneath the corrugated board sheets. There are two ways that this can be accomplished:

  1. Waterproofing material is laid directly on the label boards. And vapor barrier material is laid under the boards of the crate.
  2. Creating a false crate. This method allows forced ventilation between the waterproofing layer and roofing material. Condensed moisture will be naturally evaporated without accumulating or destroying the roof structure. The usual.

Technology for fixing corrugated board

You can use as few horizontal and vertical joints as possible when using the corrugated board roof device. This is made possible by the roofing material’s ability to span up to 12 meters in width and 14 meters in length. Most roof designs can avoid horizontal joints with these sizes.

If the roof’s design prevents you from blocking it off in length with a single sheet, you must determine the size of each sheet such that their joint rests on the crate board. The angle at which the slope slopes will determine how wide the overlap is. The idea is that there should be more overlap the smaller the angle of inclination. The roof’s minimum tilt angle should result in a transverse overlap of 20 centimeters. In addition, you should follow the guidelines to lay adjacent sheets in a single wave, regardless of the angle of inclination.

Beginning at one of the slope’s lower edges, lay the sheets. To ensure you haven’t mixed up any sheets, draw a plan for how to arrange the sheets and number each one. It is preferable to lay capillary grooved sheets from left to right. After that, every subsequent sheet will overlap the preceding sheet’s capillary groove.

Special self-tapping screws with a neoprene gasket are used to fasten sheets. The screw’s design permits you to firmly press the sheets against the crate while also providing a small amount of flexibility intended to account for temperature variations. The sheet has to be fastened in multiple locations. The screws are inserted into the corrugated board’s lower corrugation when attaching the sheets to the slope, and the skate is positioned in the upper corrugation.

Is it possible to use corrugated board on a flat roof?

The corrugated board flat roof device is primarily utilized for industrial structures. In this instance, they typically use the entire corrugated board sheet to avoid creating joints. Should this not be prevented, silicone-based waterproofing mixtures need to be applied to the seams in addition.

Installation of the skate

Should the roof feature multiple slopes, the skate will need to design the joints between the slopes. The installation process is completed at the very end. The skate element needs to be ordered with a 100 mm overlap calculated. It is advised to use the seal if the roof’s angle is modest. It’s also important to keep in mind that the seal’s primary function is to keep moisture from entering an angle rather than to form a hermetic joint. The same self-tapping screws in the upper corrugation hold the horse in place.

You can create a reliable and effective roof device out of corrugated board by following these easy guidelines. Such a roof may last up to 50 years in service. She is resilient to hail, rain, and extreme temperatures. After completing this task, you will have a dependable roof, so you can sleep soundly!
