Faltsevy roof do it yourself - installation and installation

On the territory of Russia, metal roofs are traditionally in demand; this is explained by the harsh climatic conditions that do not spoil the country's inhabitants with warm and dry weather. Despite the abundance of materials, roofing steel is considered the most reliable way to protect your home from the penetration of precipitation. Fold roof is a technology that does not lose its relevance, making the joints of metal sheets on the roof tight.

Device

The name of the seam roof was due to the system of connection between the sheets of metal, called the seam. It is a special type of seam that creates a self-snap edge. Most often there are roofs with vertically located folds, but there are also horizontal options. Roofers distinguish the following types of joints between sheets:

• Standing single fold. It is a single triangular comb, located along the edge of the metal sheet. The crest of one sheet is put on the crest of the next one and fixed on the crate of the slope with the help of clamps.
• Standing double fold. This type of seam, through which the folded roof is connected, is a double bend protruding above the sheet. The technology of joining roofing elements using a double rebate is considered the most hermetic.
• Lying single fold. In order to install the double-fold seam roof, a single bend is performed along the entire edge of the metal sheet. Most often, this technology is used to perform horizontal seams.
• Recumbent double fold. The device of a double recumbent fold consists in forming a bend along the edge of the sheet consisting of 2 turns. Compared to single, this technology has better protection against water penetration and leakage.
• Clickfaltz. A self-snap folding seam roof has, on the one hand, a decorative bend that simulates a fold, and on the other hand a spring-loaded Klykfalz. Such a device allows you to install a folded roof faster, snapping a sheet of metal on the previous one.

Note! The construction and repair of a folded roof is a laborious, painstaking process, which only a roofer with experience can perform qualitatively. The self-snap technology has become an excellent solution for those who have appreciated the high operational, decorative qualities of this type of roof, but are not ready to fork out for employees.

Types of metal

The performance qualities that a folded roof exhibits depend on the material of the sheets. Currently, manufacturers offer the following options:

1. Steel. Zinc or molybdenum-alloyed steel has the best waterproofing and anti-corrosion properties. Often, in order to further protect the roofing material, a polymer coating is applied to the surface of the steel, preventing mechanical damage to the electroplating layer, as well as giving color. The most affordable option is unpainted galvanized steel. However, repair of the roof of such material is required more often.
2. Copper. Rolled or sheet copper is considered a more durable and attractive metal for a folded roof. It can be smooth or textured, with a relief similar to the surface of a metal tile. Copper has a high decorative potential, does not enter into an oxidative reaction upon contact with water, but costs much more than the other options. Costs are increased by the fact that the installation technology involves the use of fasteners and fittings from the same metal.
3. Цинк-титан. Фальцевая кровля своими руками из этого сплава изготавливается редко, потому что он обладает хрупкой структурой, деформирующейся при незначительных повреждениях. С цинк-титаном не рекомендуют работать, если температура опустилась ниже -5 градусов, а также без специального инструмента. Virtuesми этого металла являются высокие антикоррозийные качества и длительный срок эксплуатации.

A sheet of metal, the edges of which are bent to make a folded joint, is called paintings. Roll materials prepared for installation are produced, which need only be cut and fastened on the roof slope.

Note! Installation and repair of a folding roof of copper and zinc-titanium are carried out with great care. In order not to damage expensive material, it is impossible to step on it, to put marks in the form of scratches, to throw. The service life of the roof depends on the accuracy of metal handling.

Virtues

The confidence of roofers and debt, the successful experience of using in the conditions of the harsh Russian winters, speaks in favor of the fold technology. The advantages of this type of roof include:

• High degree of protection against moisture penetration. Such a device joint seam prevents water penetration under the roofing material. The technology of the fleeting roof implies that there are no through holes in it.
• Ease. Sheets of metal whose thickness reaches 0.5-0.6 mm are lightweight and do not overload the roof frame and the foundation of the house.
• Smoothness. The smooth surface of the slopes and the longitudinal seams do not impede the sliding of snow masses and rainwater from the roof, preventing collapses and deformation.
• Long service life. Provided quality installation, compliance with the rules of operation, which are prescribed by the instruction, the operation time of the roof flange type exceeds 50-60 years.
• Fire safety. Metal belongs to the class of non-combustible materials, it does not burn, does not support combustion and does not melt.

Important! Carrying out installation and repair of a faltsevy roof, take into account that it possesses high heat-conducting and resonating properties. To minimize these negative qualities of the structure, it is necessary to use high-quality heat and noise insulation. In addition, the metal accumulates static electricity, so the fire safety instruction prescribes to equip the roof with such a cover with a lightning conductor.

Installation

The instruction cannot describe in detail how the installation and repair of a folded roof is performed. Its device is most often entrusted to a roofer with sufficient experience and knowledge. Schematically, the process of laying the roof covering looks like this:

1. On rafters of a roof the obreshetka is adjusted. So that the metal on the slopes resonates less, does not deform, the pitch between the slats is chosen in the range of 20-25 cm. For copper, the crate is nailed continuously, as it weighs more than the rest of the metals used.
2. Before installation of the coating, thermal insulation and waterproofing of the slope is performed. Experienced roofers advise treating the wood sheathing with an antiseptic composition in order to delay the repair or replacement of frame elements.
3. Roof paintings of the appropriate size are made from sheets or rolls of metal. To do this, use the drawing, scissors for metal or grinder. The edges of the paintings are folded in accordance with the type of fold to be used.
4. Pictures are carefully transferred onto the ramp and attached to the crate with the help of clamps. If the length of the slope exceeds 10 meters, moving clamps are used to compensate for changes in the size of the metallic coating due to temperature fluctuations.
5. To connect the sheets use a special tool for folding roof. It is called the faltsezakatochnaya machine. Manual bends and pliers work long and uncomfortable, so you need a semi-automatic or automatic model. For additional waterproofing seams apply a sealant based on silicone.
6. The necessary openings for the ventilation and chimney pipes are made on the surface of the slope, protecting them from moisture penetration by galvanized steel sheets or elastic penetrations.

Important! Rolled installation technology significantly reduces the time spent on roofing. It allows you to cut from the roll strip length corresponding to the length of the slope. The absence of horizontal joints between the sheets reduces the likelihood of leakage, increases the service life of the roofing.
