Modern snow guards allow you to effectively deal with the sudden melting of snow. The article offers material about snow holders for a folded roof, their functions and features of use. You will get acquainted with the varieties, parameters and a complete set of snow retention systems, learn about the nuances of choice and average prices for these useful devices.
In regions with long winters, snow accumulates and compacted on the roof, more than once it thaws and freezes. The snow mass, unexpectedly slipping from the roof, can cause a lot of trouble: damage a tree or bush, mash the car body. Much worse is that the snow cap is a real danger to the health of the residents and their pets if they happen to be in the snowfall zone. At the same time, any owner of suburban housing can make his roof not only beautiful and reliable, but also safe.
Designed and erected in accordance with building standards, the walls, the base and the roofing structure have the necessary margin of safety to withstand the snow load. In order to avoid unpleasant developments when the accumulated snow cap disappeared, snow blocking systems - snow guards, which make the process controllable and safe, have been invented and successfully used for a long time.
In addition to ensuring the safety of people and reducing the risk of damage to a parked car, the protective system performs the following functions:
Increases the life of the roof . Snegozaderzhateli stop snow gathering, the roof gets rid of the snow mass gradually. This eliminates the risk of damage to the roofing, especially if the slopes are located under each other.
Protects the drainage system . It prevents damage and drainage pipes.
Simplifies roof maintenance . Increases human safety while cleaning or repairing the roof.
The folding roof is considered to be one of the most practical options for organizing the roof. It received its name due to the method of joining metal sheets of roofing material, fold. The sealer lock reliably fastens the steel coils, while performing not only a waterproofing, but also a reinforcing function.
The features of the metal surface are the following properties:
High thermal conductivity . The snow layer from the side of the roof inevitably melts, so the snow disappears from the folded roof (if you don’t worry about the blocking system) with an enviable constancy.
Smooth surface . Smooth metal roof without the slightest bends, which are, for example, at the tile, is not able to hold the snow mass.
Taking into account the properties of this surface, installation of snow clamps on the roof for a folded roof is a mandatory measure that improves safety. The snow blocking system is mounted around the perimeter of the house, and also (necessarily) above the entrance group, roof windows, car parking. In this case, the installation of protective roofing accessories should be conducted in such a way as to exclude damage to the roofing iron and the violation of the waterproofing characteristics of the roof.
Systems for folded roofing differ from other types of fixation system; they are mounted without through holes, which allows to preserve the integrity of the roofing material.

Installation of snow retention systems is necessary in the following cases:
If housing is located in a region with traditionally snowy winters .
If the slopes of the roof are of considerable length , regardless of the shape and material.
If the roof incline angle does not exceed 50 ° (otherwise, the snow will not linger on the roof).
Snow stops can have various structural solutions and functionalities. In practical use there are several structures: plank (lamellar), pinpoint, lattice (mesh) and tubular. Tubular (first of all) and lattice varieties that combine simple installation, reliability and practicality of operation are considered to be the most suitable for the fold.
The tubular snow guard for the rebate, depending on the manufacturer, has the following characteristics:
Options . The standard kit includes two pipes (length 3 m), four supports and fasteners.
Form . The shape of the supports may have a T-shaped silhouette. The pipes are round or oval, with a diameter of 2.5-3.2 cm.
Fasteners (brackets and plates). The pipes are fixed across the ramp in brackets with holes. The bracket is tightened with screws to the folded ridge with the help of two plates; at the same time integrity of a faltsevy seam is not broken.
Additions. Weatherproof rubber seals, crimping and pipe plugs, screws and bolts will be required; use of gaskets is mandatory.

Tubular snow protectors made of the following metals are on sale:
Of draft metal . Economy items. Their low price looks very attractive, but turns into the inability of products to withstand a large load. Also, such systems are susceptible to corrosion and eventually leave traces of rust on the roofing.
Of galvanized metal . Hot-galvanized steel models have a good quality / price ratio. They are designed for long life, are of considerable strength and do not leave rusty stains.
Aluminum . They are more expensive than galvanized, but have less weight and do not corrode.
Of copper . Copper snow retention for a folded roof is used on copper roofs. This is due to the fact that in the place of contact between copper and other metal with a high degree of probability, a galvanic effect occurs and corrosion begins.
There are several types of snow guard available on the market for a faltsevy roof from domestic and foreign producers. It is widely believed that all snow blocking systems are the same, from which an erroneous conclusion is made that it is necessary to choose by price. In fact, before buying, you should decide on the following parameters:
Rate required functionality : resistance to stress and corrosion.
Pay attention to fastening system - they should be mounted on the crest of the fold.
Appearance . The decoration of the tubular system is also important because it must conform to the aesthetics of the structure.
Protection . Popular galvanized products are often covered with an additional layer of powder paint or polymer. This coating has a dual, decorative and protective role: it prevents the appearance of corrosion and improves the appearance of the product.
Quality . Preference should be given to models from well-known manufacturers, supplied with a certificate and a technical passport with an indication of the parameters.

Before buying, calculate how many snow stops you need for your roof. When the sales assistant in the store, having familiarized with the parameters of your roof, advises to install the system in two or three rows, he does not seek to increase sales. The required number of tubular snow guards is determined individually for each roof, in accordance with the norms of SNiP 2. 01. 07-85, “Loads and impacts”. It depends on such factors as:
Roof construction parameters . Take into account the type (shape) of the roof, the length of its slope, the angle of the slope.
Snow load . It is determined on the basis of the distribution map of snow regions (Moscow is included in the third snow district).
In the standard case, if the length of the slope exceeds 10 m, then installation of snow stoppers in two rows is necessary. The distance between the brackets (installation step) is set to 60, 90 or 120 cm (there are three or four brackets for one snow guard).
In fact, the folded paintings (metal sheets) often have a width of 40-60 cm. Therefore, if there is the need to strengthen the system, fastenings are placed in each faltsevy lock, and they require more.Where there is a danger of damage to property, additional rows of snegozaderzhateley; they are usually mounted above skylights, ventilation pipes and on additional tiers of the roof.
An attractive feature of snow blocking systems is their versatility - they can be installed both during the installation of the roof and during operation. Products can be selected in the color of the roof, making them almost invisible. To give the dynamics and rhythm of a large surface, you can use contrasting snow holders on the folded roof. The price for tubular snow retention systems is determined by the following factors:
Design features of . Plank models are an economical option, tubular - universal. Reinforced snow guards with oval tubes are premium.

Metal Manufacturing . The best sellers are solid and durable products made of galvanized metal, with or without coating.
Type of anti-corrosion coating . The quality of the coating depends on the durability of the snow guards and the appearance of the roof. Many manufacturers provide durable color coating in a wide color palette, allowing you to choose products to match the color of any roofing coating.
Completeness . You can purchase a kit with everything you need for installation (which is much more convenient, and, ultimately, cheaper), or buy additional items.
Manufacturer . Many manufacturing companies provide high quality products (no corrosion, durability and reliability) and confirm this with their guarantee, which can reach 20-25 years.

Many owners independently clean snow from the roof, which, on the one hand, is a good pastime in the fresh air, and, on the other hand, is unsafe for health. The task is complicated during heavy snowfalls or lack of owners. The habit of hiring a cleaning team several times in a season ultimately costs much more than installing a snow retention system. Neat and reliable snegozaderzhateley can not recall the problems of a snow-covered roof in the next 10-15 years.
