Rebate roof
Rebate roof

Self-locking rebate roofing is one of the most interesting varieties of roof covering, the main material of which is metal sheets joined together by means of a rebate. What is such a fold? These are in a special way bent sheets, which are fasteners.

The most common material for a seam roof is galvanized sheets, which cover (or do not cover) with a polymer composition. But also the folded copper roof is used, less often - aluminum and zinc-titanium.

Features and Benefits

We list the main positive aspects of coating with this type of roofing materials:

  1. a very long service life (according to the assurances of manufacturers, it can last up to 100 years);
  2. minimum load on the entire rafter system, one square meter weighs no more than seven kilograms;
  3. due to the almost smooth surface, precipitation on the roof does not linger;
  4. good characteristics on the resistance of the roof to corrosion;
  5. the availability of any color to the customer’s choice.

But there are some disadvantages that also need to be mentioned:

  • not very good noise isolation characteristics;
  • with poor installation, repair of such a roof can be difficult;
  • the manufacture and roof covering with a folded roof requires great experience in this type of work, so the invitation of specialists is strictly necessary.

How to make a folded roof?

More recently, the production process of this type of metal roof was completely manual; it was made only by high-level professionals. In today's reality, there is specialized equipment, it greatly simplifies all the processes and steps for the manufacture of blanks, and the occurrence of marriage is significantly reduced.

Machine tools make sheets better. They are able to produce sheets of different sizes, depending on the need and roof designs.

Note!

In the manufacture of the most important point is the correct rolling of metal sheets, only this, ultimately, gives the rebate roof all the necessary characteristics and brings reliability to the entire system.

If the manufacturing technology is not fully respected, then in the future this may become the source of many problems: poor sealing of joints, the use of inexpensive parts at the joints. In this case, after some time, you will inevitably have to resort to repairing such a roof.

When laying the seam roof of steel coated with zinc, all fasteners must also be of the same material. In this case, the service life of these parts will be the same as that of steel sheets. If the installation will be carried out according to the installation technology, then such a roof can serve for many years, while not requiring additional maintenance.

Material selection is an important part of roof design

We describe the basic materials for rebate roofs. Here is some of them:

Steel rebate roofing is the most inexpensive type of roof, since steel is the most common material.Light weight combined with excellent protective properties thanks to special polymer additives will allow this roof to be used for 15 years or more.

A roof made of aluminum will not be much more expensive than steel, and in terms of characteristics such as flexibility, it far exceeds it. Due to its flexibility, such a roof can be successfully used in complex projects.

Copper rebate roof

A folded roof made of copper - such a roof will serve not only for many years, but will also perfectly retain all its consumer qualities, including its protective properties. This type of roof is for those who care about not only a beautiful appearance, but also reliable protection.

The folded copper roof is practically ideal for the Russian climate. A combination of all the features, such as good weather protection, is perfect for any kind of roof.

Manufacturing technology of the folded roof

In the manufacture of steel seam roofs, galvanized sheets are used. In general, the sheets look like large canvases that can be joined by using the grooves at their edges. Therefore, such a folded roof is self-locking.

If we talk about Russia, then this type of roof appeared in our country for a long time, almost a hundred years ago, but until now it has been successfully used for many types of roofs.

There are two types of folds (lying and standing), they are needed for fastening sheets both along and across.

The most reliable mount is a double standing fold. It allows you to provide a strong and reliable joint between the sheets, as the mount is a double bend from the edges of the sheet. This mount is very common in the materials of European manufacturers. But in Russia, this species was not very popular before, as it was believed that this was too expensive a technology.

Today, with the use of modern tools and technologies, the cost of manufacturing a double fold has significantly fallen in price. Moreover, the advantages are very obvious. This is a great tightness, the roof protects better from weather troubles, drafts.

If we talk about production technologies, then there are also some differences. The roof in this case is divided into rolled and created from separate sheets. Their main difference is that the roll technology is quite new, and many do not risk using it, although it has its own advantages. It makes much easier all installation work on the roof. Well levels transverse seams.

No worse, in this regard, and sheet roofing. True, the technology of its installation is more time-consuming, but in other respects it is in no way inferior to the rolled one.

We can conclude that the rolled roof for installation work will be a more convenient material in this case than sheet.

The beauty and attractiveness of the seam roof

Folded roofing materials are used with success throughout the country, due to a number of their advantages that other roofing materials cannot boast of.

First of all, it is a stylish design, as well as the presence of a huge number of colors and shades. Therefore, it is possible to choose a roof of such a color that it does not bring dissonance into the harmonious architectural ensembles of the entire street, but harmoniously supplements it. Such a roof can cover both the old architectural buildings, and ennoble new ones.

This is probably why the rebated roof is copper, steel, aluminum is used both in private housing construction and in urban. Such roofs make cottage areas more attractive, turning them into fabulous palaces where the princesses languish in the towers.

As for the price, it will be comparable with many roofing materials. At the same time, it can be used on buildings of any type and size that the customer wishes.

Ergonomic roof features

In such a roof, no additional supports or special ceilings that are required to be erected are needed. All this is possible due to the unique characteristics of the materials themselves. At the same time, the excellent ergonomic appearance of this type of roof greatly facilitates the work of masters and specialists during installation.

Relatively small weight loads make it possible to greatly reduce the load of load-bearing walls, while, thanks to the special flexibility, it is possible to create excellent roofs of any level of complexity.

Installation work can be done as soon as possible, they do not require special equipment, additional consumables, as the technologies used allow the use of special folding equipment or use other technology of self-locking folds.

The use of fold technology eliminates unnecessary holes in the roof, which reduces the likelihood of corrosion, prevents the penetration of moisture and cold air into the room. Thus, the folded roof is a material with a long history, which has received a new birth at present due to the development of modern technologies of metal processing and instrument making.

The latest materials - reliability and modern roofs

Regardless of which material will be chosen as such a roof, in any case, it will perform its functions well. It is able to provide a sufficient degree of tightness and thermal insulation, which will make the house warm and the atmosphere cozy.

Resistance to temperature changes will make you feel comfortable at any time of the year. Though at a temperature of minus 70 degrees, at least at the same temperature, but in the opposite direction.

There is another advantage: the metal rebate roof is absolutely not exposed to fire. In other words, even if a fire happens, nothing will happen to the roof. Perhaps for this reason, the folded roof is often used for industrial needs, covering it with the roofs of hangars and other industrial buildings.

Seam roof protection, what materials are used

Polymer coatings are a very necessary component for this type of roof. They allow not only to keep the roof for many years, but also serve as a guarantee that even after the passage of time the roof will always have a good look.

Using them, you can significantly increase the protection of the entire roof, and the original color coating will not change even after decades. Polyester will reliably protect not only from sunlight, but will also give the roof a beautiful glossy shade, preventing it from scratches, while such a roof will look very beautiful.

In those regions where there is a lot of sun or where the climate is very humid and hot, a kind of seam roof like pural is best suited.

Pural is a special polymer that prevents exposure to adverse factors such as moisture, salts, and various kinds of harmful emissions.

Excellent resistance to low and high temperatures allows it to be used everywhere. It is worth noting that installation work with this material can be carried out literally in extreme conditions, even at an air temperature of 15 degrees.

The steel rebate roof also has its own additives. This is, first of all, plastisol, it gives steel sheets additional protection.

Very often, polyvinyl chloride is used to protect the seam roof. It is also added to protect sheets. He does an excellent job of giving the sheets shock resistance. But in order to achieve a good level of impact resistance, it is applied in sufficiently thick layers. This is because the layers of smaller size and protective functions are also reduced. Therefore, in this case, the thickness of the layer is of considerable importance, because it is the thickness that allows the roof to be most resistant to any damage of a mechanical nature.

But the coating of polyvinyl chloride has a rather significant drawback. Color on sheets coated with polyvinyl chloride does not hold at all. If it happened that it was necessary to replace several modules from the entire roof, then there are only two options, either paint the roof to match the color of the sheets to be replaced, or re-cover the entire roof.

However, this problem is solved. It is to buy a folded roof with polyvinyl chloride, but with an admixture of acrylic in it. After all, a coating with an admixture of acrylic will additionally add strength to the entire structure and protect the color from changes.

Buying a seam roof is not an easy task. Most likely, it will be necessary to study more than a dozen sites of construction topics in order to make the right choice. Of course, this will take some time, but it is better to carefully approach this issue. Indeed, a lot can depend on the choice by criteria such as price, quality and manufacturer, including how much the rebate roof will serve.

One of the most popular seam roof manufacturing companies in Russia is the Finnish company Ruukki. Seam roof Ruukki It has long been a recognized standard of quality, has a large selection of color solutions, and has also earned good reviews from thousands of consumers.

The color palette is simply amazing, but since the Finns are very big lovers of nature, the colors in the Finnish roof are very calm - “natural”. Excellent protective coating, polymer, performs its functions 100%. And if you consider that this is a northern country, where the climate is very similar to the Russian one, this means that the consumer properties of roofing materials from Finland should already take root well on Russian soil.

The most popular, perhaps, can be called the roof under the option - "classic". This roof has a very convenient installation method. The roof refers to rolled self-locking materials (this company is the pioneer in the field of creating such roofs).

This type of rebate roof has all the certificates of quality, so it can be safely used to decorate and protect the house for many decades.

Model folded roof Ruukki "Classic", has a very attractive design. Simplicity, but at the same time both completeness and elegance of all lines. All this gives room for the fulfillment of all the fantasies of the designer for the embodiment of the roof - a dream.

In conclusion, I want to emphasize once again that the most different types of seam roofs have many advantages: strength and durability, relatively low weight, resistance to fire and other adverse weather conditions, as well as an acceptable price. All this makes the folded roofs very popular not only in the private, but also in the industrial sector of building construction.
