Fold roof device

Despite the rather large variety of roofing materials and technologies, many people consider the construction of a folded roof as the main option for covering the house. However, it is first necessary to understand what a folded roof is, as well as what technology is used for its construction.

Note! Fold roofing is called such a coating, in which adjacent elements are connected with the help of folds. Fold is a special type of seams, in which the pre-prepared edges are interconnected by crimping.

As a rule, steel sheets are used to make a folded roof. More often it is galvanized metal, less often - painted. Sheet thickness is 0.46–0.8 mm, and the size in width is about 700 mm (on average). Seam seams are of two types:

• downhill;
• standing.

Lying seams are used to connect sheets of material used when laying the roof horizontally. The standing seam joints are necessary in order to join the seams running along the slope. Also among these types there are such types of folds as single or double.

A hand tool can be used to create a folded joint, or, if available, power tools. For more convenient work today also materials have been produced that have folds that snap into place after docking. If you use such sheets, the tool may not be needed.

If we talk about tightness, then the best performance in this respect is a double standing seam joint, which looks like a longitudinal joint of a pair of roofing paintings (that is, an element of material with prepared edges).

Advantages and disadvantages

It should be noted that in the roofing structure with the help of folded joints there are both advantages and certain disadvantages. So, if we talk about the merits of this:

• relatively long service life;
• material does not give in to corrosion;
• the finished roof is lightweight;
• the surface of the roof is smooth, which provides easy access from the roof of snow and rain.

Here are the disadvantages:

• sound insulation is so weak that during bad weather (for example, rain) you can hear drops falling on the roof;
• rather complicated installation - do not do it with your own hands without skills, we need specialists, and there are not so many of them;
• choosing a material, it is difficult to create a suitable aesthetics of the roof of inexpensive materials, such as galvanized steel, and the roof of copper looks more attractive, but it is much more expensive;
• the need to build a lightning conductor, since the material is able to accumulate electrostatic voltage.

How does the folded roof?

The following types of metals are commonly used for the installation of a folded roof:

1. Roofing galvanization with a thickness of 450–700 mm, which will last up to 30 years.
2. Steel for roofing with a coating of polymeric materials; possesses rather high indicators in relation to the anti-corrosion coating and decorative properties, the service life is the same.
3. Roofing sheets of copper, usually they are released in rolls, which can have a varied relief. For example, copper rolls after rolling can successfully imitate shingles. This roof theoretically has the longest service life - about 100 years.
4. Roofing aluminum is slightly less durable - about 80 years.
5. Titanium-zinc - it is difficult to work with it during installation, however, if you fully comply with the installation technology, such a roof will be almost eternal.

The nuances of editing

During installation, the roof on the folded joints should be constructed entirely by technology. So, faltsevoy roof can be used for homes whose roof has a slope of 14 ° or more. If it is arranged on the roof with a slope of 7–14 °, then double folds should be used, as well as an additional seal on the seams (silicone-based gasket).

Note! It is equally important that all consumables used for the connection (for example, a lot of nails, various bolts and even wire) are made exclusively of galvanized steel. If this condition is not met, all parts intended for fasteners will soon deteriorate, resulting in the need for repair of the roof.

When a hard roofing is arranged, it is necessary to properly conduct a series of works on the device of thermal insulation and hydro-barrier. In addition, it is important to qualitatively perform the ventilation system of the space under the roof itself. Otherwise, condensation will form on the inside of the sheets of metal lying on the roof, which will spoil this coating.

The roof can be installed on the crate, as, indeed, on a solid basis. If the framework for the roof is a wooden or metal crate, then it is important to type it in such a way that the calculated step is observed.

Note! Calculated step is the distance between two adjacent rafters, equal to half the width of the sheet. If the roofing material has a small width, then the rafter step can be equal to it.

What happens if the rafter pitch is not taken into account during the construction of the batten? Metal sheets should usually be mounted around the edges and center. If their attachment is different, then the sheets may begin to sag and deform.

In such places where the roof will adjoin the wall or be near the passing chimneys and pipes, you need to arrange a solid foundation. When the roof is broken and has a rather complicated shape, a solid foundation will be the most optimal solution.

Traditional installation technology faltseva roof

The technology, which is traditional for the device folding roofs, is used by many people, however, more advanced installation methods are known. To understand which way suits you, it is better to consider both.

So, traditional technology. If guided by it, the work should be divided into four main stages:

• paintings are made that are used to cover the slopes and other roofing parts (such as gutters or overhangs);
• the finished pictures are raised to the roof, then they are joined by a standing seam (usually single, less often double);
• to the crate installed before this pictures are fastened with clamps; one of their ends is wound inside the fold, while the other is attached to the bars, which make up the crate;
• the latest - on all existing holes (if any) install special aprons made of galvanized.

When sheets with a length of 10 m or more are used, it is best to fasten them to the crate with floating clamps — then the roof will remain as airtight, despite possible thermal deformations.

Modern installation methods faltsevoy roof

Nowadays, the most commonly used technology is called “roll”. It differs from the traditional one in that metal sheets are delivered to the construction site in packed rolls. There, using special tools, these rolls are cut into paintings to the required length. In this case, there is no need to make joints of sheets horizontally, as a result of which the roof tightness improves.

Note! Connecting the picture is well done with an electro-mechanical tool that creates double standing seam, the seams are sealed with silicone.

The advantages of modern technology are:

• ease when choosing the length of the picture;
• the use of rolling mills (mobile) makes it possible to make the connection with high strength and excellent tightness;
• hidden clamps, used as fasteners, make it possible not to use hardware, as a result of which the metal will not be subject to corrosion and the life of the roof will be long.

The nuances of editing кровли из цинк-титана и меди

Beginning the installation of galvanized titanium roofs, it is important to ensure that those who do the installation work with sheets very carefully. So, the sheets should not be thrown, it is forbidden to put any marks on them, and even less to scratch them. For marking it is best to use a construction marker. If the outdoor temperature is less than 5? C, it is better not to start work on the roofing.

To work properly with titanium-zinc, you should use tools specifically designed to work with it. These are bending pliers, scissors (straight and shaped) and other equipment. In fact, the same requirements are relevant when working with a copper roof. Moreover, copper is allowed to be laid exclusively on the crate, made solid.

Folding roof fencing

Why do you need a fence on the roof? First of all, to reduce the rate of convergence of snow cover accumulated on the roof during the winter, and also to prevent the possibility of harming the life and health of people who pass under the roof. Also falling precipitation does not damage landscaping (bushes, trees), located below.

Fencing нужно еще по одной причине – во время работ на кровле увеличивается безопасность рабочих на крыше, выполняющих там периодическое обслуживание швов и поверхности. Также можно предотвратить вероятность повреждения водосточной системы.

Fencing on the roof should be constructed in accordance with such regulatory documents as, for example, SNiP 21-01-9. It indicates that on any roof, the angle of which is 12? and less, and the height of the eaves 10-11 m, you must have a fence. The same applies to roofs with an angle of more than 12? with a height of more than 7 m.

It is important that the fence was aesthetic - it is best to use a profile pipe or similar building materials. Paint the fence need only polymer paint based on powder.

It can be summed up that the folded roof is the most practical option for building houses and repairing roofs, the main thing is that all work should be carried out in accordance with the technology. The roof can be erected both in private houses and cottages, and in buildings of administrative type.
