In the conditions of severe Russian winters, when heavy snowfalls form large snowdrifts, in order to increase the safety of the inhabitants of the house and passers-by, as well as to avoid damage to the roof itself and standing next to the equipment, special snow retention devices have been developed. They are mounted on any roof. Roof snow holders fit perfectly into the architectural environment, are not susceptible to corrosion, do not rust.
The principle of operation of such systems is to pass snow layers in small parts and prevent their avalanche-like convergence. It should be noted that in European countries the installation of snow retainers is a prerequisite for the commissioning of facilities with a sloping roof, as well as for insurance policies.
What are the snow retainers on the roof for?
These systems are designed to protect people from accidents and many troubles that can happen when large snow masses leave the roof of a house. The consequences of uncontrolled snow melting are as follows:
- threat to the life and health of the inhabitants of the house;
- damage to the architectural elements of the building and vehicles parked nearby;
- roof damage;
- penetration of roofing of roofs with a complex profile, where the slopes are located one above the other;
- damage to gutters, breakage of hooks, inversion of the gutter;
- threat to trees, shrubs, flowers and various ornamental plantings.
Tubular snow retention
These designs produce several types, but the most popular and universal option today is the tubular snow retention, which is suitable for most roofs. The system consists of three steel supports, in the openings of which two pipes are inserted, with a diameter of 25-30 mm, and a wall thickness of 1.5 mm. Pipes can have a round or oval cross-section. The distance between the support brackets is approximately 100 cm.
Due to the fact that the anticorrosion coating is applied to the surface of the snow retainer and mounting brackets , the system has a long service life.
Such designs are made of different types of metals: steel, aluminum or copper. But it should be borne in mind that the copper version is used only on copper coatings, because when combined with other types of metals during operation, a galvanic effect will occur, the consequence of which can be the destruction of roofing materials and the weakening of bracket fasteners.
Installation of snow retainers
As a rule, tubular snow retention is installed on roofs made of the following roofing materials:
- metal tiles;
- seam roof ;
- corrugated board.
Most often, such structures are located above the windows, entrance, parking, etc. It is recommended to install a tubular snow retainer simultaneously with the roofing - this is more convenient and much cheaper.
Installation of the structure on the roof is simple. The location of the system is determined taking into account the following parameters:
- snow load;
- the length of the slope of the roof;
- angle of inclination.
Depending on the data given, the distance between the brackets is calculated, which can be 600, 900 or 1200 millimeters.
The issue of installing such systems is best thought out in advance, before the start of roofing. However, if this still has not been done, it’s okay, since the elements of the snow retainer can be attached to almost any roof surface using screws with weatherproof rubber sealing bushings, which ensures the tightness of the roof.
The location of the structure is parallel to the cornice (at a distance of 35 cm from it). Also, the tubular snow retention must be placed above the dormer-windows, and in case the length of the roof slope is more than 8 m, the installation of an additional row of snow retention system is needed. Fastening is done through the roofing material to the crate.
Installation can be done in a row, joining separately taken sections, or in a checkerboard pattern.
It should be noted that the tubular universal snow retainer in no way spoils the design of the roof of the house. It will fit perfectly into the overall picture of the building, since today in the building materials markets it is easy to choose a structure that is similar in color to the color of the roofing material.
Grand line snow retainers
The tubular snow retainer Grand line is a simple and reliable way to protect people and equipment from the consequences of uncontrolled descent of snow from the roof. This is a great addition to any roof, protecting it from slipping and providing additional reliability.
Advantages of Grand Line Snow Retainers
The designs of this company have a number of advantages:
- The tubular snow retainer, the price of which is from 1000 rubles per 1 meter, is fully galvanized.
- Warranty is 25 years.
- The warranty period for the safety of appearance is 10 years.
- Hermetic fastening to the roofing is performed with washers-seals.
- Joining products simplifies crimping on snow retainer pipes.
- There are additional stiffeners on the support.
Conclusion
So, snow retention is the most important security element of the roof and the area near the house
Thanks to this straightforward device, you can avoid a number of problems:
- deformation of the roof under heavy snow mass will not occur;
- the gutter and other roofing elements will not be accidentally damaged;
- water drips will not appear on the ceilings of rooms on the upper floors;
- without fear, next to the house you can put a car.
