Prefabricated elements are considered to be products made of metal and used for the design of joints on different fragments of the facade and roof. To such elements it is possible to carry: various laths and the fads, calculated for registration of places of joining of every possible details. they are produced in different colors: dark red, rich chocolate, marsh.

Additional elements of the roof - the cost
Approximate value of the elements can be about 10% - 15% of the total cost of the roof. In cases where a roof of a complex shape is being constructed - the sum of the costs of the elements may exceed 15% of the boundary.
Most buyers tend to think that sales managers are specifically imposing this product to increase the total amount of the check. In fact, things are different. In addition to improving the decorative appearance, additional elements are of great practical importance - they protect the roof from leaks.
Produced either from pure galvanized steel, or from the same steel, but with the addition of a polymer coating. The installation of the fittings on the roof is a delicate and demanding task. Since the main function of good is protection (from snow, dust, penetration of moisture), illiterate erection will distort the main task of the device.
Types and purpose of the dobors
Skates- multifunctional fragments of the decor, designed for seams when laying metal. Skates are additional elements for metal roofing, necessary in any case, despite the type of roofing and are used to close the upper edges of the roofing.
Skates are produced in three types: ordinary, rounded, and also with the presence of gaps for ventilation. On the end part of the skates are fastened plugs. In parallel with the installation of skates, experts advise you to mount a seal specially designed for such work. It is excellent to protect the roof from penetration of various small debris, foliage and the like.
Windshield - Aesthetic fragment, protecting the roof from the penetration of precipitation. Such a bar is fastened to the end part of sheets of metal tile.
It performs the following functions: protects against precipitation (rain, snow), destructive influence of strong gusts of wind. In addition to this, the wind barrier is assigned an equally important aesthetic function. In cases where the bar is missing for some reason, the entire arrangement of the roof truss system will be viewed.
Cornice lath - not an unimportant additional fragment, designed to protect the cornice wooden board from the water draining from the roof.
The absence of this bar will eventually lead to the rotting of the wooden material and will significantly reduce the period of its exploitation. Such a bar is mounted under the flooring of metal. In addition to protecting against penetration of moisture, the bar protects against penetration of insect pests into the cornice board and does not allow birds to build nests on the cornice. Especially it is important for homes located outside the city on the backyard. Similarly, additional elements for the corrugated board are used.
Planks of contiguity They are used in cases where roof overlap is performed at several levels or if other structures adjoin the house.
Such slats are mounted by analogy with the mounting of the ends.
Endowa - is necessary for the design of joints on roofs that have more than one ramp. They are placed under the tiles and direct the flow of water directly into the gutter gutters.
Distinguished two kinds of valley - the lower and upper. The lower one is located under the roofing material, it is designed to protect against precipitation and their branches from the slopes, has a wider width than the upper one. At the bottom of the valley metal tile is mounted, and on it - the upper valley. The upper end is mainly intended to improve the decorative appearance of the structure.
For economy, often, the bottom valley is made of zinc. It is located under the roofing material, so it is not noticeable. The saved amount will not be very large if the roof is simple. If the roof is broken, then the savings will be more tangible. The upper valley is usually ordered a color that is as close as possible to the shade of the roofing material.
If the owners are confident that the ceiling of the roof is performed by highly qualified specialists, then it is possible to lay only the bottom endowment. To design this option, installers will need to perform the perfect cutting of metal.
Snow Holders. According to the majority of this element of the roof is not mandatory, but according to experts this statement is mistaken. Particularly need such elements in cases of use by residents of the area around the building. Such a device prevents the avalanche of sliding snow masses. When the snow slides, injuries to the upper torso can be obtained by adults and children, and vehicles parked near the building can also be damaged.
Snow holders are divided into several types, they can be:
- tubular,
- lattice,
- point,
- plate.
Punctual are used only on the roof covered with flexible tiles. They are placed on the roof in staggered order. Produced in the form of small corners.
Latticed - fastening in the form of a lattice, located along the edge of the roof, able to keep in the past snow and pieces of ice.
Tubular - are considered the most durable and most reliable. They are assembled from two pipes, a set of special fasteners and brackets. On the roof of the corrugated board or metal roofing are fastened with screws to the crate. They are usually chosen in the tone of the shade of the roof.
Ornaments for the roof
This type of goods include spiers, wind direction indicators, weather vanes and the like. On them lies only the aesthetic load, in other words, they give the building its originality.
Specialty stores offer a variety of options for such products. The cost of goods of this kind is quite loyal.
Some useful tips
Important recommendations from the builders regarding the selection of the gates:
- it is much more profitable and practical to buy everything for a roof and a facade from one manufacturer;
- the dyed and metal tiles of the same color ordered in different companies can in fact be of different shades;
- having made the order of a material for roof overlapping and rebounds in one firm and at disclosing having found out various colors of materials - it is enough to phone to suppliers and to order replacement of the bought goods (having issued the order at different suppliers, if necessary, replacement will make much more difficultly);
- ordering in one place all the elements to cover the roof for shipping have to pay only once; delivery will be required in any case, because the additional elements produce a certain width and length, and the material for manufacturing has not a small weight;
- making a purchase of building materials of this type, you must remember about the mandatory design of the guarantee.
