Prevent an avalanche of snow coming off the roof is only one way - put a snow stop. But not everyone knows that these devices are, what types they are and how to install. I am ready to talk in detail about this useful elements of the roof.
Snow stop to prevent an avalanche gathering snow from the roof
What is a snow guard, and how it works
Snow stop is a low fence, which are installed at the edge of a sloped roof. They can be arranged or sections have the form of a continuous rail. Often, they are installed only on important objects such as sidewalks, balconies, car parks, etc.
When the snow melts, this guard detains snow, causing it to melt and drip in the form of water. It should be remembered that snegoupora effectiveness depends on how well it matched. The fact that the size and design of this element are selected individually, depending on the angle of rays, their length and the heavy rainfall in the region.
At more than 60 degrees with the roof angle is not adjusted snegoupory
On roofs with a slope angle more than 60 degrees for the detention of snow fences do not set since no snow accumulates on the roof surface.
Next, consider what are the different types of snow guard and when they apply.
Depending on the design, all of the existing snow stop can be divided into several types:
types of snow guard
Tubular snow stop formed as fences, arms, interconnected by a plurality of tubular beams. the latter diameter is typically 15-30 mm. The total height of the enclosure does not exceed 15 cm.
Usually snegoupory tube made of galvanized steel and painted on top, allowing them to choose the color of the roof.
Tubular snegoupory have the highest strength
I must say that this design refers to snegorezam, ie it is not completely snow delays and cuts its seams, which ensures its descent from the roof of the small parts. It may be necessary to protect it from destruction, for example, the gutter system at home.
- Strength. Tubular snow stop considered the most reliable, they can be used in all regions. Moreover, they can be installed on roofs with any angle of inclination;
- Ability to use for any roofing. Tubular snegoupory use metallocherepichnoy and standing seam roofing, as well as for roofs made of soft materials or even natural tile;
- Practically invisible. If you choose the right color, the snow stop practically invisible.
Tubular snegoupory established one continuous row along the eaves
Installation of tubular snow guard carried a solid number. In cases where the snow load is very large, they are placed in two rows.
Disadvantages. The disadvantages include the impossibility of snow retention.
Cost. The price of these snegoupory ranges 850-1200 rubles per product length of 3000 mm (price valid until spring 2017).
Lattice snegoupory composed of vertical grids and brackets
Lattice snow stop for the roof structure are composed of vertical grids, and brackets that perform the function of the fastening element. I must say that the size of these barriers can be very different.
Most often they perform the barrier function, which fully retains the snow on the roof until it has melted. In addition to snow and small delay lattice icicles.
As a general rule lattice snegoupory used for roofs with a pitch length and a sufficiently large bias, ie, in cases where there is potential for convergence of large lumps of snow.
Grilles are able to completely prevent the snow melts
- Securely retain snow. Lattices may be installed above the important objects;
- Versatility. Fixing brackets exist for any roofing.
Disadvantages. The minus is the smaller strength compared with the tubular structure by virtue of features. Therefore, in cases where it is assumed a large snow load, behind bars to brackets fastened round or oval pipes.
cost of. Price trellis snow holder usually starts from 1500 rubles. 2.5 m.
In the photo plate snegoupory
Plate, or otherwise angled snow stop installed in cases where the snow load is small. Most often they can be purchased complete with metal tile and floorings. In this case, the fence painted in the color of roofing material, which makes them invisible.
The construction of these articles is very simple - they constitute a triangle made of sheet steel. Like metal, the product surface is galvanized and coated with a polymeric composition.
- Low cost. These products are much cheaper and tubular lattice analogues;
- Large selection of colors. This allows you to choose the color of the product under the roof.
Most snow load can damage the plate snegoupory
- low strength. These snow stop delays are not suitable for large amounts of snow;
- Restricting the angle of inclination. Can not be installed on the roof with an inclination angle more than 30 degrees, which is also associated with low strength.
Lamellar snow stop installed in a staggered manner in two rows. If there is potential for convergence of the relatively large amount of snow, you can install them in three rows. The distance between rows is from half a meter to one meter.
Cost. Corner guards 2 meter cost about 200 rubles.
Yoke is used as additional protection from avalanche snow melting off the roof
Spot snow stop unable to hold a large amount of snow, since, in fact, constitute triangular shaped brackets. Therefore, they are used as a complement to the trellis or tubular structures.
Moreover, they are often used for soft roof with a slight slope as the main snegoupora. The fact that the rough surface of the soft top itself holds good snow.
Yoke is used for the roofs of the soft tile
dignity. The positive aspects include the low cost and effectiveness in terms of insurance. Snow stop point can take some of the load of snow on themselves and thereby protect the basic snegoupory from damage.
disadvantages. In addition to the inability to use the yoke as independent snegouporov to disadvantages include the fact that their attachment is carried out during mounting of roofing material.
Cost. One yoke costs about 50 rubles.
A few words about the installation
As I mentioned above, the installation of snow guards carried out by means of brackets - they are selected individually under the cover profile.
Installation of snow guard carried on top of a roofing material by means of bolts
Install of snow guard on the roof of corrugated or standing seam roof made brackets with flat soles. Their attachment to the sheathing is performed in the lower wave.
Snow guard is fastened to the roof by the roofing material with screws 8h60 mm. mounting space required to be sealed with rubber gaskets.
Install snow guard carried on a supporting wall. If you set the design of the overhang, the overhang may break under the weight of snow. Exceptions are those cases where the overhangs formed rafter.
Keep in mind that the smaller the step brackets, the stronger obtained snegoupory. Therefore, at about 60 degrees incline step should be no more than 50 cm.
If the ramp is longer than 5.5 meters, you need to install their own hands two rows snegouporov.
Now that you know when and what is set on the roof snow stop. Additionally, check out the video in this article. If some of the nuances you do not understand, ask questions in the comments, and I will answer you.
