Actual, stylish and reliable roofing material, which is perfectly combined with various architectural styles. Thanks to the classic lines, this material will appeal to even the most conservative individuals.

The main feature of the double standing seam is its versatility, not only because of its appearance, but also its technical characteristics and methods of fastening.

This roofing material is suitable for sloping roofs and comes in a wide color palette.

Fold seam and its types

A variety of seam seam guarantees the quality of the roof, its tightness and strength.
We use two types of seam seam:

Double standing seam is one of the most reliable, representing a longitudinal connection between adjacent seam paintings. The edge of the seam has a double bend. There is very little chance that water will somehow penetrate the seam, or the steel sheets will start to diverge over time. In this case, the fold can be rolled up either manually using special tools, or with the help of a folding machine.

Clickfaltz is also very durable. Two pictures fasten with each other without the use of special tools. This saves a lot of time installing a folded roof.

At faltsevy roofs a huge variation in price. Since the seam is not a material, but a technology. The material can be any - budget (galvanized), elite (copper), intermediate options. Consider what it is, profitable or unprofitable, what is the price per m2 of folding roof and how much it justifies itself.

  What is the fold?

Fold is the connection of two sheets of metal, in which the edges are bent together in the same direction once (single fold) or twice (double). Double fold is more reliable and more tight, at all critical places (ridge, knots) perform it.

The seam is formed in two steps: bending of the fold (if you work with sheet / roll material, and not with the finished picture) and crimp.

The electric machine performs everything in one go.

Two or more sheets that connect on the ground and as such are raised to the roof are called a painting. Pictures are also called blanks with already curved edges. Some materials (galvanized, copper) are not sold in sheets, but in rolls: on a small roof, the picture may not have a single fold, the slope is covered with a whole stripe along the entire length. Locks will only be on the combination of the paintings between themselves.

The fold can be standing or lying down (the lock is bent parallel to the sheet). Lying horizontal stripes connect the metal, the castle looks down the line of the weir. Perpendicular to the ridge (along the slope) make standing. There are also paintings with self-snap folds, they are connected to each other on the principle of the groove / crest.

  Advantages and disadvantages of seam roofs

Pluses of a faltsevy roof:

• low weight due to the small thickness of the metal (usually within 0.8 mm).
• due to the small thickness - flexibility, the ability to cover including curved roofs;
• water resistance: a fold is more tight, than fastening by a hardware.

• the roof is more susceptible to mechanical damage than metal profile coatings;
• disadvantages of any metal roof: thermal conductivity, lack of sound insulation, electrical conductivity, electrostatics, the roof is hot in the heat;
• snegozaderzhateli necessarily need: because of the smooth surface of an avalanche of snow.

Durability and cost can not be attributed to the advantages or disadvantages: they depend on the material. The more expensive the material, the more durable the roof: simple galvanization serves no more than 10-15 years, copper and zinc-titanium - more than half a century. They look the most elegant.

  Basic rules for folding roofing

You can lay the roof on a continuous or sparse crate. In the second case, it is necessary to carefully observe the design step so that the coating does not sag. For the manufacture of sparse crates used:

• timber 5 by 5 cm, conifers soaked in antiseptic, humidity not more than 12%;
• board 3.2 by 10, similarly;
• metal profile with anti-corrosion coating (preferably used for paintings with self-snapping folds).

If the crate is continuous, a vapor diffusion film is placed on top of it, directly under the coating. If sparse - then under it.

In the presence of insulation the structure of the cake is:

• heat-insulating material (fit between the rafter legs);
• contra-lattice;
• waterproofing membrane;
• crate.

  The price of metal for a faltsevy roof

Estimated cost of material in Moscow:

• simple galvanization, sheet 1 by 2 meters - from 400 rubles, the service life of 10-15 years;
• polymer coated is 15-30 years depending on the polymer. Price is proportional to durability. Polyester - from 400 per square meter;
• purex - from 500;
• pural - from 600;
• aluminum - from 1.5 thousand per square, serves up to 50 years (warranty - 40);
• zinc-titanium from 3 thousand per square, serves up to the century;
• copper - from 3 thousand to 150 years.

Prices are for sheet and roll materials. Metal for a faltsevy roof can be released in the form of preparations with already bent edge. In this case, the price is not much higher. But the cost depends strongly on the manufacturer. 400-600 rubles for steel with polymer coating is the price of Russian brands. Imported more than 2 times. For example, paintings with Ruukki self-latching folds from polyester cost from 900 rubles per square, pural - from a thousand.

It should be noted that the acquisition of expensive metals on the roof justifies itself: they are almost eternal, because they are not afraid of corrosion. The interaction with air and water produces a patina on the surface. It does not reduce the strength of the material (like, say, iron oxide), but on the contrary, it prolongs: the patina layer reliably protects the sheets from corrosion. And it looks noble.

As for steel roofs - they, alas, do not last forever. In simple galvanizing, the resistance to external factors decreases as the zinc is washed off.

To extend the service life, the roof is regularly painted with oil paint (at least once every 2-3 years). Non-galvanized metal on the roofs (and generally for street work) cannot be used. Polymer-coated steel is safer than simple galvanizing, but the coating itself is very capricious. It is easy to scratch it during installation, and if you do not immediately paint over the scratch with polymer paint, corrosion will begin to develop at the site of damage.

For comparison, other popular roofing coatings should be mentioned.

Metal tiles on average cost about 300 rubles per square, the service life - up to half a century.

It also has a polymer coating, but there are advantages over the folded roof:

• well ventilated, less affected by condensation;
• mechanically stronger: profile waves serve as additional stiffening ribs.

Flexible tiles also cost about 300 rubles. Serves depending on the brand and model from 20 to 50 years. Absolutely sealed. There are no metal cons: heat / sound / electrical conductivity. You will not cut the curvilinear roof with metal tile, but you can flex it. In contrast to the folded roof (the slope of the roof is 7–30 degrees, the optimum is 10–15) with bitumen tiles it is possible to cover slopes of any steepness, up to negative surfaces.

Ceramic tiles to the budget cover does not apply, from 1000 rubles. Lifetime is practically unlimited: in Europe there are houses with ceramic roofs built two years old and older. But, unlike all the listed roofs, pottery is heavy. Need a reinforced truss system.

  Price for folding roof work

The territory of Russia is characterized by harsh climatic conditions in which cold and high humidity prevail. This explains the high demand for metal roofing of the country's inhabitants. It is roofing steel that can be called an ideal protection of a structure against the effects of various atmospheric phenomena. Fold roofing is considered to be one of the current technologies, due to which the joints of metal sheets are completely sealed.

  Fold roof device

Fold is a special type of joining of sheets of metal, which was the basis for the name of the roof. Fold connection is a special seam created by a self-snapping edge. Vertical folds are most popular, but horizontal joints are also encountered.

Specialists in roofing work distinguish several types of folded roofs:

• Standing single folds. They are made in the form of a single ridge along the edge of the metal sheet. To connect the combs of sheets put on one another and fixed on the crate by means of clamps.
• Standing double folds are the result of a double bend protruding above the surface of the roofing sheet. Vertical double fold of the roof ensures tightness of the connection.
• Lying single folds are formed by a single bend of the sheet edges.
• Lying double folds are formed as a result of double bending of the sheet edges.
• Klikfaltsy are elements of the self-snapping folded roof. Such a view assumes the presence of a decorative bend on the one hand and a spring-loaded Klikfalts on the other. Installation of roofing is easier and faster, since it is enough to snap the sheet edge on the previous element.

The construction and repair of a folded roof can only be done by an experienced roofer, since the process requires a lot of patience and effort. With the advent of self-latching technology, the seam roof became more accessible for connoisseurs of aesthetics and high quality.

  Types of metal for the manufacture of rolled faltsevoy roof

The quality and performance characteristics of the folded roof are determined by the material for the folded roof.

Modern manufacturers offer several options:

• Steel sheets. High waterproofing and anti-corrosive properties are characteristic of zinc alloyed steel. To enhance these qualities, the surface of the sheet is coated with a polymer, which gives color and protects the galvanic layer from damage. Unprotected galvanized steel is cheaper, but more often requires repair work.
• Rolled or sheet copper. This material is characterized by its attractiveness and durability. There is a smooth and textured copper roof or similar metal tile. Copper is characterized by the absence of an oxidative reaction when combined with water, the cost of such a coating is quite high, but it pays off due to its decorative potential. When choosing copper for a folded roof, it should be borne in mind that, according to the technology, fasteners and accessories should also be copper.
• Zinc-titanium alloy. For self-production faltsevoy roof this alloy is used very rarely. This is explained by the fragile structure, which is able to deform with the slightest damage. It is recommended to work with the material only if special tools are available at a temperature not lower than -5 0 С. Among the advantages, particular attention is drawn to the long operating period and excellent corrosion resistance.

Sheet metal with curved edges for folded connection is called a picture. In addition, roll materials are produced, they are most often ready for laying, it suffices to cut them into certain segments and fix them on the crate.

Copper and titanium-zinc coatings require careful handling to prevent damage to expensive material. It is also not recommended to step on the cover, scratch it or throw it. Careful handling contributes to the extension of the service life of the folded roof.

  Main advantages

The main advantage of the faltsevoy technology is the possibility of operation in the harsh winter conditions that prevail in Russia.

In addition, sloping seam roof has the following advantages:

• High level protection against moisture penetration. Water cannot penetrate under the roof covering through such a seam. Fold technology implies the absence of through holes.
• Low weight. Sheet thickness does not exceed 0.6 mm, which contributes to reducing the load on the roof system and the foundation of the structure.
• Smooth surface. The slopes of the fold type roof have a smooth surface over which rainwater and snow mass roll down without obstacles, without loading the roof and preventing its deformation.
• Long period of operation. High-quality installation and proper operation, the corresponding instructions from the manufacturer, extend the service life of a folded roof to 50-60 years.
• Resistance to fire. Metal cannot burn, sustain burning or melt.

Having chosen the roof of the fold, you should carefully examine all the characteristics of the material. Particular attention should be paid to the high thermal conductivity and the resonating properties of the metal. The solution to the problem is to use high-quality insulation and sound insulation. The ability of metal to accumulate static electricity requires the installation of lightning rods.

  Installation of a cattle roof with a double fold

Not everyone can install or repair a folded roof independently, most often this work is transferred to experienced roofers.

In general, the laying of such a roof is carried out according to the following scheme:

• Elements of the batten are nailed onto the rafter legs, maintaining a pitch of 20-25 cm; for the copper roof, the batten should be solid.
• Also in the faltsevoy roof includes insulating and waterproofing layer. At the same stage, wooden frame elements are treated with antiseptic agents.
• Next, proceed to the manufacture of paintings using sheets or roll material. Metal is cut with special scissors or grinder. The edges are folded in accordance with the selected type of fold.
• The finished picture is raised to the top and fixed on the crate using clamps. When laying the material on the slope, the length of which exceeds 10 meters, use mobile clamps. This compensates for the change in the size of the metal under the influence of changing temperature.
• The connection of the sheets is carried out with a special tool for the folded roof - with a folding machine. This semi-automatic or automatic model speeds up the styling process. You can take the installation of the fold manual bend and pliers, but in this case the process can drag on for a long time. Waterproofing perform silicone sealant.
• In a certain place of the slope, holes are made for the chimney or ventilation, which must necessarily be protected from moisture by galvanized steel aprons or penetrations.

Installation of a rolled faltsev roof not only simplifies the process, but also reduces the time for its implementation. From the rolls can be cut into strips corresponding to the length of the slope. At the same time horizontal joints are completely excluded, which minimizes the risk of leakage and increases the service life of the roofing material.

A modern folding machine is used to create blanks for different types of folds. I will talk in stages about the principle of operation, types and popular models of machines, as well as explain how to make a folder with your own hands.

Production technology

The faltserokatny machine is irreplaceable both at arrangement of the faltsevy roof itself, and for production of auxiliary roofing accessories. These include elements of the gutter system, frontal and end overhangs of the roof, as well as using it to make ventilation boxes made of galvanized.

Types of folds

The folded joint is a twist between two adjacent sheets of metal, and in order to equip this twist, you need to bend the seam on the edge of the sheet, and this is exactly what the folding machine needs to bend in this fold.

Folded connections exist 2 - this is a single and double fold, plus folds can be standing and recumbent.

• Single fold  It is considered the basis, here one sheet is simply bent under 90º, and on the second sheet a peculiar hook is made and after connection this hook is crimped;
• Double rebate  can be called a single analog, only twisting is done in 2 turns. In order to wrap the metal, the size of the hook in the workpiece must be less, on average about 5-7 mm, and the height of the workpiece is the other way round, more.

As for recumbent connections, they are exactly the same as standing ones, only wrapped on their sides.

Now quite often there are L-shaped roofing folds, there is no practical benefit from such a connection, it is no better and no worse than a double bend, but many consider that this way the roof looks much more effective.

When selecting equipment, please note that there are machines for arranging recumbent folds, standing folds and versatile units that can be rebuilt as needed for any type of bend.

General information about the machines

The main advantage of a faltsevy roof is that the covering turns out monolithic, without any fixing or connecting openings. But the roofing metal itself is quite thin and making blanks in production, and then transporting them to the object is inconvenient, and often unrealistic.

A small folding machine radically changes the situation. With such equipment, you can make blanks directly at the facility, moreover, there are models that can be installed directly on the roof.

There is one more important nuance: a folding machine is needed to bend the edges of the sheets, and a folding machine is used to make a double fold and pressurize the connection, bringing it to the final result.

Often the thickness of the metal for roofing fluctuates around 0.5-1 mm, with a maximum of 1.2 mm. But a good machine for a folded roof is calculated for work with metal from 0.3 to 1.5 mm.

Such equipment is closer to the professional one, and it is possible to make not only roofing pictures on it, but also to bend the workpieces for various kinds of drainpipes or ventilation pipes, plus to make end gutters and ridges.

By the way, the blank under the folded roof (strip of roofing metal with curved folds) is called “Picture” among professionals.

The principle of operation of the unit is simple: any faltserokatny machine has a number of crimp curly rollers, which actually bend the edges of the sheet. Crimp rollers are installed in pairs on the crimp rollers.

The number of such crimping shafts can be different, but, no matter how many, they are driven by a gearbox, and the gearbox itself rotates due to an electric motor. There is, of course, equipment with a manual drive, but the performance there is very low and such devices are rare.

How to assemble the machine yourself

Not every master can afford a folding machine, so quite often people assemble such devices manually. A homemade folder certainly does not have such a wide range of functions, but it will cost only 2-3 thousand rubles.

Illustrations	Recommendations
	Appearance. Our homemade folding machine is designed for operation in the workshop. This fixture is screwed to a wooden workbench, but if you weld legs for it, this machine can be easily transported.
	Device. The whole structure consists of 3 parts. In the photo on the left, the arrow points to the base part, everything is welded and screwed to it. In this case, a metal corner with a 75 mm wing was used, but this is a minimum, if you take a corner of 100 mm, the device will only benefit from it;
	From above, 4 garage hinges are welded to the carrying corner. A crimp punch (No. 1) will move on these hinges; A bounding shelf (No. 2) is screwed in front, but a so-called bending tooth is still inserted between the shelf and the base angle, it forms the folds; Both the shelf itself and the crimp punch are made from a 75 mm corner, plus the handle must be welded to the crimp punch, I made it from a conventional pipe. The biggest problem is to pick ideally flat corners, I gave the corners to the milling machine, otherwise the folds will be crooked.
	Scheme. First, the front structure is screwed to the base corner, that is: A gasket is put on the fixing bolts, in my case a metal strip 1 mm thick was used; I put a crimping tooth on the pad; I made it from a band saw blade. I managed to get a canvas 1200 mm long, so the working length of the device was 1200 mm, but it’s better to do it under a standard sheet of 1250 mm. Before installation, I removed the chamfer from the canvas; The support shelf is put on the bolts last, after which all this is delayed. It was not for nothing that a band saw blade was chosen for the crimping tooth, and a particularly strong, stiff metal is needed here.

Folding roof - a great option for roofs with a slight slope. The German masters invented the folded roofing (perhaps you guessed it by name). In translation, "fold" means only a gutter, and from such simple connections the installation of a folded roof also consists - snapped or squeezed, and that was that. But why then, with such simplicity, a folded roof occurs infrequently?

The problem is that before the fold was made from sheets only by hand. The process was laborious, the joints were not very smooth and it was difficult to speak about the tightness of such a roof. And only with the advent of professional equipment, the folded roof opened itself anew: straight joints, any length and speed of installation did their job. Want to know more?

The roof, which is made of individual metal sheets, called folding. In Russia, the folded roof appeared a little over 100 years ago, and quickly gained its popularity. And with the production of mechanical and electrical sealing tools (before the seam was connected only by hand) its installation became available to all. See for yourself:

Of the benefits:

• Low weight of the roof, which is valuable for any buildings.
• Excellent leakage protection. All thanks to the tightness! Nowhere on the faltsevy roof at all there are no through holes that could become a hotbed of corrosion or other problems.
• Folding roofing is also attractive because of its ease of installation, which virtually anyone can handle.
• Such a roof can be made not only on ordinary pitched roofs, but also on more complex architectural objects.
• Seam roof looks aesthetically pleasing and is combined with any type of building materials.
• The main advantage of the folded roof is the 100% tightness of the roof covering, under which neither snow nor rainwater can sneak. The fact is that in such a roof there is a minimum of holes, in contrast to a metal profile, which means minimal risk of moisture getting into the roofing space. No corrosion!
• 20 years minimum service life. In principle, seam roofing and durable due to the fact that its compounds are not available for water. Plus, there are no transverse seams and open joints that would prevent water flow and snow.

And still quite simple installation:

We note immediately that all the flaws that are usually attributed to the folded roof come from the wrong installation.

• So, the most common complaints are about the loud noise from the rain, when drops just drum on the folded roof. To avoid this, the crate must be used ideally flat, then the metal sheets will fit snugly enough and not create a noise effect.
• Periodically repair of folds is necessary. It depends on how they were made and what.
• Snowfall avalanche. Yes, on such a flat roof, he has nothing left to do, how to move out quickly, but why then snederderzhateley? In Europe, for example, even the house is not insured, if there are no such elements on the roof.
• Simple design and lack of a rich selection of colors and textures. Yes, not everyone likes the minimalist aesthetics of a folded roof. But the matter of taste is always a subjective matter, and someone just as well already does not want to see the omnipresent metal tile.

And now look what else you can do to get rid of the noise:

The choice of design and material

To be comfortable, we offer to start a little to understand the concepts.

Pictures  - These are rectangular metal elements with folds, which are mounted on the roof. The standard form - steel sheets in the form of a rectangle with carved corners. From the paintings and spread seam roof.

Falts  - this is a specific seam, which is obtained due to the bond between different metal webs. The advantage is that with such a connection the density is quite high, and neither sealants nor adhesive compositions are needed to ensure complete tightness. And, besides its main task, folds play the role of more ribs for the entire roof.

Clammer- This is a special piece of fasteners, which are nailed directly to the base of the roof. A simple clamp has the same shape as the future billet of the fold, and the movable one provides the future thermal expansion of the metal (compression and stretching at different times of the year).

As you can see, everything is simple and you don’t have to bother about anything.

Material for making paintings

Make a faltsevy roof both from galvanized steel, and from different non-ferrous metals. Here are the materials from which most often make a folded roof:

Option # 1 - steel

The most common option. The steel faltsevy roof can be galvanized, not galvanized or in addition covered with polymer. Of the benefits - corrosion resistance, low cost and durability (60 years of service).

But over time, steel, unfortunately, noticeably tarnishes. And therefore for the device of a faltsevy roof steel pictures need to be taken only such which are covered with a color multilayered covering. And when buying one, make sure that there is a special protective film on them - only this way the material is not scratched during transportation.

But in any case, even a high-quality polymer coating on the roof will not be durable: due to sunlight, acid rain and the most important enemy - a humid maritime climate.

Option # 2 - copper

This is the most beautiful roof that just burns on a sunny day. Its main advantage is that no biological animals will take root on it, especially moss. But there are a lot of minuses - such a metal is a bit soft, it requires careful handling and is quite expensive.

With time, copper is also covered with a patina - a layer of oxides, and becomes dark brown. And after that - green, and nothing needs to be restored. And precisely because of oxides, copper cannot be combined with other materials on the folded roof.

Copper faltsevoy roof is also valuable for its flexibility - it is easy to make roofing architectural masterpieces by it, not to mention simple roofs:

Option # 3 - Zinc

Zinc rebate roofing is additionally covered with a protective layer - zinc carbonate. Over time, this roof gets a chic silver-gray color. Zinc roofing is about 50 years old, which is relatively short, and therefore in Europe such material is not used for making paintings.

Option # 4 - Aluminum

Such a roof is the most resistant to mechanical damage and corrosion, and can last more than 100 years! A pleasant silver shine will only please the eye.

In addition, this material is lighter than steel and more resistant to corrosion. But aluminum is bad because it expands and shrinks much more when temperature drops. That is why the installation of such a roof has its own characteristics:

Option # 5 - zinc-titanium

It is a strong, successful alloy of zinc and titanium: zinc is not susceptible to corrosion, and titanium has both strength and ductility. This sleep is also valuable for designers, because over time it is covered with a noble patina. The roof looks great!

Option # 6 - aluzinc

Aluzinc is an aluminum-zinc-coated steel painting that has valuable self-healing properties and perfectly protects scratches and cuts from corrosion.

Option # 7 - an alloy of three metals

Titanium-zinc-copper alloy. There is not much copper here, only 0.005%, but this is enough to give the roofing material plasticity, thanks to which profiling is facilitated.

Special coating

If your home is located in a seaside area or in a zone with a poor environmental situation, or simply with a hot and humid climate, then purchase folded paintings covered with purals. Only this polymer is capable of protecting at a high level from sea air, rains with acid impurities and scorching ultraviolet radiation.

Production technology

The folded roof is also divided according to the production technology - cast and rolled.

It has long been used in Russia was cast roof, and its reliability has already been tested. It is easy to assemble such a folded roof with your own hands and without special tools, there are no transverse joints, and the surface is complete and durable. But rolled seam roof - this is a new technology with its own advantages and disadvantages. These are metal strips for the entire length of the slope, and immediately with the prepared edges on a special machine. The fold is formed double.

And according to the width of the paintings and the presence of stiffeners, the folded roof is divided into the following types:

• Double rebate and two stiffeners. Such a roof is most in demand in the industrial sector. She broke warehouse and large buildings with a very different slope of the roof. Standard width - 5.57 m, working width - 5.45 m.
• Double rebate and two stiffeners, but less width - 35.2 m (working 3.4 m). This roof covers the roofs of cottages, large residential buildings and historical monuments.
• Double rebate without stiffeners. Such roofs are also two types, based on the actual width - 5.57 m and 3.52 m. Both are quite suitable for residential buildings and ordinary private houses.

And still fold panels can also be privates and starting, trapezoid and parallel:

Market offers

If we talk about brands, in Russia, as well as abroad, the most popular Finnish folded roof from the company Ruukki, with self-snapping folds.

More pleasant prices - for the materials of the domestic plant "Insi". It has been on the market for more than 16 years, and is quite pleased with the quality of its products. In the production there are both ordinary glossy and matte paintings, as well as unique ones, for creating a special design of the roof.

Installation technology faltsevoy roof

For the installation of such a roof, neither special supports, nor expensive lifting equipment, nor additional consumables are needed.

Stage I. Preparing the Foundation

It is possible to arrange faltsevy roofs both on an obreshetka, and on the continuous basis. Both bars and metal hat profiles are suitable.

It is only important to adhere to the step between the rafters of no more than 2.5 meters - otherwise even the strongest steel sheets risk bending and the seams will immediately disperse:

And here is how to bend the lining sheet by yourself:

Stage II. We work with pictures

You can bring both finished paintings and rolled steel to the workplace, which you will cut off on the spot.

As soon as the steel paintings are ready, they are raised to the roof. Lay out along the eaves directly on the batten and begin installation from the middle.

Stage III. We harvest additional items

For roofing the edges of the roof, valleys, ridges, and such elements as the chimney, the roof joint and the dormer window, it is necessary to pre-fabricate ready-made paintings from rolled steel - but already in figure form.

Here is a detailed master class on how to make yourself a drip for a folded roof:

Stage IV. Bend folds

So, we have come to the most important technological question: how to make folds?

Types of compounds

The folds in such paintings are single and double, standing and recumbent. If to simplify, then all horizontal folds are called lying and vertical ones standing as standing:

A single standing seam is the easiest to install:

Double rebate is a double bend edge. It must be done in the most problematic areas of the roof, where snow and water usually accumulate - valley, troughs and other complex compounds. It is the strongest and most airtight, which is why the most popular abroad.

A double standing rebate is recommended for roofs with a slope angle of less than 25 °. True, in Russia a double rebate is still considered an unreasonably expensive technology. Although in fact the price is exceeded quite a bit, but the reliability of such a connection turns out to be much greater. Here is how you can make it in the process of mounting the roof:

But, if you want the seams between the paintings to not be views, and the whole roof looks even - then make recumbent folds. Yes, and horizontally, the pictures are connected only by lying folds - so that the coverage is maximum. If the captured steel strip does not reach the depth, such pictures will eventually diverge.

The third type is an angular standing seam, which is also called L-shaped. It is recommended for roofs with a slope of more than 25 °. In performing it is easier than the usual fold - you just need to correctly bend the upper edge of the seam.

Stiffener height

Now let's talk about the height of the fold, which also serves as a stiffener for such a roof. The fact is that this compound is absolutely waterproof, if only it is not subjected to stagnant water. But where on the roof can it come from? Very simple - from the thickness of snow. That is why the fold height is important, and in especially snowy regions it is made considerable.

Additional sealing

Additionally, in order to prevent water from entering the seam, special sealing gaskets are installed in the seam even during the installation process. A special material is used that calmly transfers the effects of high temperatures (up to 90 ° C) and compression, as rolling mechanisms will still be used for folds.

Another important point: all fasteners that you will use should only be anti-corrosion. Otherwise, after a couple of years, a new beautiful roof will be covered with rusty streaks.

Fold bend technology

It is possible to fasten the folds to each other with a hammer and wooden bars, special hand tools or with the help of electromechanical machines. The easiest option - frame:

Before you bend the recumbent fold, the picture must be attached to the flooring with a separate narrow strip in order to stabilize its position.

The bend is made from the front and back, and to the left and right are the vertical elements of the subflot.

Klyammer application

The most common method of fasteners - klyammery. They are bent down by 25 mm, and the paintings are nailed on the right side.

Klyammer - a metal strip of galvanized steel, 80-120 cm long and 0.5-0.7 mm thick. You can cut the clamp from a usual galvanized sheet with a simple hand tool. Next, place the clams on the edge of the paintings every 60 cm and fasten with screws (4.8x28).

So, first put the picture on the crate, then fasten it with a clamp and only then cover it with another picture. The cleats should be nailed along the line of joining two pictures: one sheet is placed on the cleats above, and the second one is pushed from the bottom, and three layers of metal are wrapped in one direction, after which we close the folds to the end. We press, and we get a strong and reliable connection with the clamp, which is hidden inside and holds both sheets on the roof. Such fastening is a 100% guarantee for many years from leaks and cold air.

And now let's see what makes a professional work different from an amateur one. So, for an ordinary home wizard with quite dexterous hands, a single mallet, scissors, and a crook hook are enough to install gutters. But an experienced person, an expert in his business, is armed with at least a dozen expensive special scissors, not to mention frames, tongs and other tools. Moreover, the total cost of such a kit may be more expensive than the folding machine itself.

To close the folds today is often used semi-automatic tool, the use of which gives a lot of significant advantages:

• High performance.
• High quality seam.
• The preservation of the polymer coating paintings.
• Ability to work with metal of any thickness.

Recently, paintings have also been made, the folds of which easily snap into place when pressed - and no tools!
