Why are Snow Holders so necessary?
When performing roof installation, structural elements are used that form a passive roof safety system. This system includes various types of snow chains, roof fencing, all kinds of roofing ladders, a variety of roofing bridges and so on.
Installation of these devices is of great importance, it makes it possible: to carry out a planned cleaning of the roof, the necessary repair of pipes, to clean the gutters from dirt and debris, to proactively inspect all junctions, serve antennas, and ventilation outlets.
These devices are matched to the color of the roof and do not violate style and architectural ideas. Snegozaderzhateli for metal, installation of which does not entail a significant cash infusion and cost of effort, will be an effective element on your roof.
Thanks to the use of various modern technologies, snow holders are performed without visually visible seams and at the same time have a rather aesthetic appearance. They are made of galvanized steel, which is subsequently coated with polyester. In addition, it is possible to create them from aluminum and copper.
Characteristics and variety of
structures These devices have the undeniable advantages of :
- they reduce the likelihood of ice and snow masses falling from the roof of the building;
- excludes damage to the vehicles standing near the building;
- minimizes the likelihood of damage to human health;
- simplifies access to roof maintenance and repair;
- prevents possible damage by snow masses of rainwater systems, as well as building elements.
Snowshooters are latticed, plate, tubular, as well as point. The first three are usually mounted on the roof cornices, the last view is mounted on its slopes.
The most common and popular type are tubular snow holders. This design allows you to keep from falling even thick enough, caked layers of snow. Usually this kind of this device is used on the seamed roofs.
For a metal roof, the most commonly used trellis snow arresters, which stop even a very thin layer of snow and ice. Such snowshooters, as a rule, are attached to special clamping supports, which allow to abandon the additional bar, which can weight the structure.
On the roofs of flexible tiles the supports of these elements are fixed with screws to the roof lath. Many manufacturers of roofing materials initially produce a special roof tile with supports, which are subsequently installed snegozaderateli.
The strength of this element is directly dependent on the size, as well as the cross-section of the support angle, which provides the grille attachment.
Tips for installing snow holders
Specialists advise you to take care of buying snow coverings for the roof in advance, even before the installation of the roofing. This allows you to lay a support board in the places of their installation, thus, additionally fixing the roof.
Also when buying such a device it is necessary to consult with the masters, tk. This element must be approached to the house and roof. As a rule, in the standard set of snowstopper for metal roof there are fasteners, rubber gaskets, screws, and, in fact, the tube itself with the compact.
When you put snow covers for metal, installation is made next to the cornice, but always in the place of abutment of the bearing wall. Removal from the eaves is selected in each case separately, but the fastenings are fixed only in the region of the bearing wall.
The required number of fasteners is calculated taking into account the length of the roof slope, the slope of the roof, and also from the design of the crate. Typically, the distance between adjacent anchors varies from 0.5 to 1 m or equal to the distance between adjacent rafters.
Fastening is carried out by screws through a sheet of metal tile to the crate. The holes for the screws are sealed with rubber in this way: the upper mount is one rubber gasket, the lower fixing to the crate is two rubber gaskets.
