Roofing a house is a very complex structure. There may be various devices and devices. One of the roof designs are snegozaderzhateli. This is an optional, but necessary element. The fact is that during a snowy winter a lot of snow can accumulate on the roof, and if this mass comes off suddenly, it can cause a lot of trouble. In this article we will talk about how to install snow guard. Let's talk about their varieties and features.
It is necessary to install a snow stopper. He will be able to protect you from accidents and court proceedings, in case of damage to someone else's property during the “avalanche”. And which one to choose? What types of snow protectors are commercially available?
The most common option is lattice structures. They are made of metal and can be installed on almost any type of roof. Lattices are quite effective and they are usually used to protect against the collapse of snow masses in high-rise buildings. Such constructions can be mounted both in a nailing and mounted way.
The lamellar type of snow clamps can be installed on the metal tile and profiled sheet.
Such constructions do not work well if the angle of inclination of the roof is more than 30 °.
Lamellar designs are made of the same material as the roof, and are relatively inexpensive.
Mounting of a plate snow guard
You can install snow stoppers on a roof made of soft material. They have a hook design. Very often, these snegozaderzhateli set as an additional protection. Thanks to the use of modern technology, snow stoppers are made of transparent material, which makes them less noticeable.
Another universal (independent of the roof type) snow guard is a tubular one. It is a bracket with attached tubes. This design holds the snow no worse than lattice.
Among the whole variety of snow guard designs, the most common are lattice and tubular. They are quite effective and are great for all types of roofing. We will talk about the installation of such products with our own hands.
Snow protectors hold a snow mass
Before starting the installation snow holders, it is necessary to determine the place of their installation. Installation can be made both during the construction of the roof, and already at the operated facilities.
The number and place of installation of snow stoppers is determined based on several factors. Namely:
Installation in two rows
If the roof area is large, and even snow falls a significant amount, there should be a lot of snow holders. They can be installed in several rows, staggered or only in dangerous areas. According to the recommendations of experts, with the length of the slope of more than five meters, devices for snow delay should be put in two rows. In other cases, depending on the amount of precipitation.
Also the number of devices will depend on the type of roof. The metal tile and professional sheet which are popular today is a smooth material. With a slight heat (for example, on a sunny day), the snow from such a roof will actively fall. Therefore, it is on such a roof that the snow guards are simply necessary.
As a rule, snow retention devices are mounted above skylights, walkways, entrances, and other areas where a large mass of snow may harm property or human health.
When installing, a minimum of 50 cm should be retreated from the eaves. The only exception is installation of lattice structures, provided that the eaves are formed by the roof truss legs.
Snow latches in the form of grids have recently begun to yield to the palm of tubular structures. But still they are also widely used, as before. That lattice products can often be found on the roof of tiles.
Installation of the tubular snow guard
The mounting principle of both types is the same. The only thing that lattice structures can be installed directly on the eaves of the roof.

Installation takes place in the following sequence:
In this way, you can install devices for snow retention on almost any type of roof.
Snow stops on the roof
The installation of snow stoppers on a soft roof is slightly different.
If the slope of the slope is less than 15 °, the installation of such devices is generally not advisable. Also, the formation of "avalanche" is unlikely in the presence of sprinkling of stone dust. That is why powerful snow traps are not installed on a soft roof, the presence of snow stoppers is quite enough.
Snow stops on a soft roof
Such devices are placed in a checkerboard pattern. The installation itself is made by simple screws. At the same time, it is not necessary to reinforce the crate. Firstly, snow stoppers weigh little. And secondly, the soft roof keeps within on a continuous type of an obreshetka. If the slope of the slope is large, then it is possible to mount both tubular and lattice snow holders.
When installing such structures on a soft roof, there is always a risk of damage to tightness. Therefore, the mounting holes must be carefully sealed. This can be done using rubber gaskets or any sealant.
