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 nearby equipment, special snow retainers have been developed. They are attached to any roof. Snow guards on the roof fit perfectly into the architectural environment, are not subject to corrosion, do not rust.
The principle of operation of such systems is to skip the snow layers in small parts and prevent their avalanche convergence. It should be noted that in European countries, the installation of snow guards is a prerequisite for putting into operation objects with a sloping roof, as well as for issuing insurance policies.
Why do we need snow guards on the roof?
These systems are designed to protect people from accidents and many troubles that can happen when large snow masses come off the roof of a house. The consequences of uncontrolled snow melting are as follows:
- threat to life andthe he alth of the inhabitants of the house;
- damage to the architectural elements of the building and vehicles parked nearby;
- roof damage;
- breaking roofing of roofs with a complex profile, where the slopes are located one above the other;
- damage to gutters, breaking hooks, inversion of gutter;
- threat to trees, shrubs, flowers and various ornamental plantings.
Tubular snow guards
These designs come in several types, but the most popular and versatile option today is a tubular snow retainer, which is suitable for most roofs. The system consists of three steel supports, into the holes of which two pipes are inserted, with a diameter of 25-30 mm, and a wall thickness of 1.5 mm. Pipes can be round or oval. Between the support brackets, the distance is approximately 100 cm.
Due to the anti-corrosion coating applied to the surface of the snow guard and mounting brackets, the system has a long service life.
Such structures 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, which may result in the destruction of roofing materials and loosening of bracket fasteners.
Installation of snow guards
As a rule, a tubular snow retainer is installed on roofs made of the following roofing materials:
- metal tiles;
- rebated roof;
- profiled.
Most often, such structures are placed above windows, entrances, parking lots, etc. It is recommended to install a tubular snow retainer simultaneously with the roofing - it is more convenient and much cheaper.
Installation of the structure on the roof is simple. The location of the system is determined by the following parameters:
- snow load;
- roof slope length;
- tilt angle.
Depending on the given data, the distance between the brackets is calculated, which can be 600, 900 or 1200 millimeters.
It is better to think over the issue of installing such systems in advance, before the start of roofing work. However, if this is still not done, it's okay, since the elements of the snow retainer can be attached to almost any roof surface using screws with sealing sleeves made of weather-resistant rubber, which guarantees the tightness of the roof.
The arrangement of the structure is parallel to the cornice (at a distance of 35 cm from it). Also, a tubular snow retainer must be placed above the skylights, and if the length of the roof slope is more than 8 m, an additional row of snow retaining system must be installed. Fastening is carried out through the roofing material to the crate.
Installation can be done in a row, joiningindividual sections, or in a checkerboard pattern.
It should be noted that the tubular universal snow retainer will in no way spoil 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 you can easily pick up a design that is similar in color to the color of the roofing material.
Snow guards from Grand line
Tubular snow guard Grand line is a simple and reliable way to protect people and equipment from the consequences of uncontrolled snow drift from the roof. This is a great addition to any roof, preventing it from denting and giving extra strength.
Advantages of Grand Line snow guards
The designs of this company have a number of advantages:
- Tubular snow retainer, the price of which is from 1000 rubles per 1 meter, is fully galvanized.
- Warranty is 25 years.
- Guarantee period for the preservation of appearance - 10 years.
- Implementation of hermetic fastening to the roofing is carried out with sealing washers.
- Docking of products is facilitated by crimping on the pipes of the snow retainer.
- There are additional stiffening ribs on the support.
Conclusion
So, the snow retainer is the most important element of the safety of the roof and the territory near the house
Thanks to this simple device, a number of problems can be avoided:
- there will be no deformation of the roof under heavy snowweight;
- drainage and other roofing elements will not be accidentally damaged;
- Water drips will not appear on the ceilings of rooms on the upper floors;
- you can safely park your car next to your house.
