Doborny elements for a roof from a professional flooring -

Decking is considered a practical, inexpensive and durable roofing material, therefore, is actively used in private low-rise housing construction. High operational and technical characteristics of this coating, which are complemented by ease of installation, make the profiled sheet indispensable for the construction of roofs of any shape, type or slope. The more complex the roof configuration, the more in the design of the valleys, joints, junction points with vertical surfaces, the valleys, edges, at the device of which it is almost impossible to join the roofing material without gaps. To prevent leaks, blowing of cold air, shaped elements of the roof of corrugated board are used. In this article we will tell you how to select and install them correctly.

Composition and characteristics

Doborny elements for a roof from a professional leaf are made from high-quality galvanized steel. They are used to protect the nodes of the junction of corrugated board and the joints between the roofing sheets from leaks, penetration of cold, blowing wind. They are produced in 3 types:

• Galvanized unpainted. Such additional elements are made of unpainted galvanized steel, they are the cheapest of all, but they do not last long, since galvanic zinc coating is easily mechanically damaged.
• Galvanized painted. Shaped elements for roofing made of profiled sheet, painted with a special composition are more expensive and last longer. As the paint and varnish covering serves as protection for metal, preventing emergence of corrosion.
• Galvanized and polymer film. The polymer coating applied to the surface of the shaped elements for the roof of a “premium” class professional sheet prevents the metal from contacting with moisture, reliably protecting it from the appearance of corrosion centers. Such products are much more expensive, however, during the operation they keep an attractive appearance for a longer time and perform protective functions.

Note! Usually, the color of the additional elements for the roof is selected from the professional sheet in tune to the coloring of the roofing material. In order for the match to be perfect, it is necessary to purchase profiled sheeting and shaped products from the same manufacturer. Then, visually, the roof will look holistic and aesthetic.

Functions

When building a roof from a profiled sheet of a complex configuration, there are nodes of abutment of the roofing material to vertical surfaces, edges between slopes, valleys and other joints, which, as a result of poor-quality installation, often become leaks. Before the start of mass production of special products for embedding these plots, builders and homeowners managed with improvised means, using scrap sheets, roofing material, however, these “handicraft” solutions spoiled the appearance of the roof and also performed their task poorly. Additional elements produced by modern manufacturers perform the following functions:

1. Waterproofing. First of all, fittings perform a protective function, preventing leakage into the gaps formed during installation of the roofing material. Leaks inside the truss frame have a negative effect on the condition of the insulation and wooden structural elements.
2. Decorative. When laying a professional sheet in endov, skate, gable and eaves overhangs, ugly joints and unprotected edges are formed, which spoil the appearance of the structure. If you close the nodes with shaped elements in tune to the roofing material, they will not stand out, creating a holistic and harmonious image.
3. Protective. Eaves and end strips protect the wooden elements of the rafter frame from contact with water, extending the life of the roof.

Please note! The more complicated the roof design, the more used “doborki” for installation. Additional elements of the roof of the profiled sheet are relatively inexpensive, especially if you compare their cost with similar products for tile roofing. However, a large number of shaped elements can significantly increase the cost of overlapping the house.

Kinds

The use of special protective and decorative elements requires many roof nodes from a profiled sheet. Therefore, the production of this destination has different sizes, shape and purpose. All finishing products are made of galvanized steel with paint or polymeric coating. Manufacturers of professional flooring produce the following types of shaped elements:

• End plate. This part is used to protect the joints of the roofing material from moisture leakage, as well as for the equipment of gable overhangs. She covers the last sheet of corrugated 50-100 mm, protecting from contact with water. The end plate is attached to the roofing or ridge screws.
• Eaves plank. The function of the ledge strip - the discharge of rain and melt water into the drainage system. This element masks the eaves board, protecting it from moisture, it is installed on the last rail to the crate with painted roofing screws.
• Scallops. Spurs with internal and external angle are used to protect the nodes of the pairing of roofing material with a wall, pipe or other vertical surfaces from moisture, dust, wind.
• Endovy. These additional elements are used for knocking equipment between adjacent slopes of roofs of complex configuration. Endovy produce upper and lower. Products installed below perform a waterproofing function, and the top - a decorative.
• The horse. The ridge element for sheeting is used for the equipment of the joint of slopes at the top point, it performs a waterproofing and decorative function.

Note! The most popular shaped products for corrugated roofs are ridge profiles, end and curtain strips. They are used for the construction of roofs, even the simplest design.

Ridge profile

The ridge profile has the greatest variety of forms and types among shaped articles. In the construction of the roof of the profiled sheet, this element performs 3 functions at once. It protects the joint between water penetration, cold air or dust, forms a ventilation gap that improves air circulation, and also improves the appearance of the roof. Manufacturers produce 3 types of ridge profile:

1. Plain. It is a simple corner of painted galvanized steel with mounting shelves 100-300 mm. The wider the shelf product, the more effectively it protects the joint of stingrays from moisture. A straight ridge profile withstands intense wind loads, but it can be easily mounted with your own hands.
2. U-shaped. A ridge profile for roofs made of profiled sheet with a u-shaped edge between two mounting shelves is used if you first attach an auxiliary wooden beam to the ridge connection.
3. Полукруглый. Ridge profile в виде полукруга стоит дороже остальных моделей, однако, эффектно, оригинально выглядит. Он изготавливается для крыш с разным уклоном, поэтому имеет крепежные полки различной длины. При установке этого элемента обязательно используют заглушки, защищающие торцы конька.

Note that the installation of the ridge profile for the roofs of the profiled sheet is carried out using a special seal that follows the contour profile of the roofing material. It protects the penetration of liquid, dust, snow or cold air streams below the ridge.
