In winter, it is very important to protect the building from an abundant thick layer of snow, which melts or freezes when the temperature drops, forming a strong ice sheet on the roof surface. Ice layers may begin to fall down over time, so it is important to install snow retainers for the roof in a timely manner. Why are they needed and what are the features of their installation?
Main goals
Thanks to the installation of snow retainers, several problems can be solved:
- Avoid possible damage to gutters, roofing elements.
- To protect passers-by from possible fall of ice and layers of snow.
- The roof will not deform and bend under the weight of the snow mass, while the ceiling will be protected from water leaks.
- The decorative elements of the building and the plantings next to it will not be damaged.
- Installation of snow retainers allows you to save time and money that may be required for the reconstruction of the roof and its deformed components.
- The main objective of these structures is to protect the roof and extend its life.
The main thing is risk reduction
Snow load on the roof is an indicator that determines the thickness of the snow layer that affects the roofing system. Snow holders for a roof made of metal tiles and other roofing materials are a good opportunity to protect the building itself and everything near it in time from falling snow mass. Modern models of snow retention can be of several types:
- tubular;
- corner
- trellised;
- lamellar;
- point;
- in the form of hooks.
You need to choose the type of device depending on the type of roof and its cover, as well as climatic conditions. They must be installed using safety devices, and if the building is higher than 6 m, it is necessary to arrange a fence along the perimeter of the roof.
Features of tubular and trellised snow retention
Tube and trellised snow retainer for metal tiles is a universal tool that is ideal for installation on a rolled or sheet roof, as well as on a roof covered with natural tiles. These robust structures can even be mounted on sloping roofs. It is worth remembering that if the angle of the roof structure is 60 degrees or higher, then the snow load will not be taken into account. This is due to the fact that the snow cover on such a system does not last long.
The most dangerous roofing systems - with a standard small slope. There are several reasons for this:
- Due to the large area of the roofing surface of the snow, much accumulates on it.
- The angle of inclination in such systems is 20-35 0 , so a lot of snow accumulates, and this mass also disappears entirely.
- Snow retainers for the roof on such a roof will be subjected to a large static and dynamic load.
Hooks, Plates, and Corners
These products have been widely used on roofing systems coated with roofing material or Euro tile. Such devices are mounted during roof installation or overhaul of the coating itself. The installation of snow retainers in the form of hooks is carried out in several rows in a checkerboard pattern around the entire perimeter of the roof. Fastening products is carried out directly to the crate.
If the roof is covered with tin, metal tiles, corrugated board, then you can not do without the use of lamellar angular snow scoops. These elements are good because they are made from the same materials as the roof itself. At the same time, installation is possible on an already finished roofing system. True, these products have disadvantages - they do not differ in strength and durability.
If the roof is soft?
Due to the peculiarities of the structural structure, the equipment of the soft roof is performed somewhat differently. Firstly, according to construction standards, when arranging such a roofing system, the maximum slope angle is not more than 15 0 . This serves as a guarantee that the roof will be almost flat, and therefore the risk of convergence of snow will be minimal. Secondly, the soft roof has a rough surface. On top of the roofing material, as a rule, stone crumb is placed, which prevents the sliding of snow. Thirdly, when installing snow retainers for a soft roof, it is not necessary to make any design changes.
Features of installation on a soft roof
If you care about the condition of a country house or office space, as well as passers-by on which snow avalanches can collapse, be sure to install snow retainers for the roof made of metal: these products are installed during roofing or already on the finished roof. The installation process is as follows:
- About 50 cm should be retreated from the cornice.
- Placement is performed in several ways: tubular fit in one line, corner and point - in a checkerboard pattern.
- If the slopes of the roofs are large, long, and there is a lot of snow, snow retainers are installed in two rows with an interval of 5-5.5 m.
- Tubular products are attached to the crate by means of screws, which reduces the load on the roof.
- The fasteners should be 60-110 cm apart, and all openings must be hermetically sealed.
What to do with metal?
Roof snow holders play an important role, especially if the climatic conditions of the region involve constant and severe snowfalls. To perform the installation of devices on a roof made of metal, you need to perform a number of works:
- First, the correct type of supports is selected, the distance between them is calculated. It is important to take into account the power load, and the type of roof, and the type of lathing, and the diameter of the rail. The expected load depends on the material and how it is fixed.
- For a long roof and a steep slope, the supports should be placed in several rows, evenly distributed over the entire length.
- If the snow retainers for the roof are of high quality metal, they do not need to be treated with an additional coating.
- Before installing additional elements of the roof, you need to check the places of future fasteners for strength.
- The installation of snow traps is carried out above the external load-bearing wall near the eaves.
The installation of snow retainers is best thought out even at the design stage of the roofing system.
What to choose?
Snow holders for roofs made of metal and other roofing materials are presented in a wide variety. They differ in design and are designed for different roofing. The simplest and most effective option is to give preference to trellised snow retention, which will cope even with small pieces of ice. These products are perfect for installation on tiled country houses. The cheapest option is lamellar snow catchers, which can be mounted on the roof with metal tiles. They are well suited for this material both in composition and in external characteristics. True, they do not provide reliable protection, and they require a certain angle of slopes - not more than 30 0 .
When tubular snow retainers for a roof made of metal tiles are installed, fastening is performed over the bearing wall, parallel to the edge of the ramp using self-tapping screws, screws. But for a soft roof, it is best to use point (or tubular) products that will enhance safety and improve the protection of drains.
If tubular structures are being installed, the following should be considered:
- You will need a standard crate in steps of 350 mm (for metal tiles) and 400 mm (for corrugated board).
- Installation is carried out using a special universal bracket.
- Most often, the product comes complete with plastic seals, which allow you to achieve a high degree of tightness and prevent leakage.
BORGE brand: what's so special?
Representatives of the company pay maximum attention to ensuring that the houses are comfortable, safe and comfortable for living.
