Every winter, snow suddenly falling from the roofs causes troubles, and sometimes even accidents. It injures people and also damages property. This could have been avoided if building owners had installed snow retainers on the roof.
Basic design of snow stoppers
Snow retainers must only be installed after selecting a suitable design. Among others, a lattice variety can be distinguished, which has the form of brackets rigidly fixed to the roof, with lattice compartments located between them. Such designs are made of rectangular corners, as well as pipes and frames. The crossbars act as reinforcement. If it is necessary to extend the structure, shorter sections must be joined together.
Roof snow holders, the types of which are described in the article, can be tubular. In this type of brackets are fixed to the roof crate or rafters. Metal pipes are passed through them. Depending on the distance between the pipes and the space between the lower pipe and the roof, it will be determined how much snow this device can hold. If it is known that the design should be more powerful, then the strength can be increased by reducing the distance between the pipes.
For reference
Roof snow holders, the types of which can be very different, should evenly distribute the snow load on the roof surface. In the case of tubular snow stops, their installation should be carried out along the line of the bearing wall.
Features of snow stoppers in the form of hooks and angular, as well as plate structures
Hooks are hooks that will not hold the snow in large volumes, so they are suitable for roofs with regular cleaning. They are chosen for soft structures that are covered with shingles or any other similar materials. Usually hook-shaped snow holders are used as a complement to other devices of this purpose.
Do-it-yourself installation of snow retainers can be carried out by any home foreman, plate or corner structures that perform their function on metal roofs, as well as structures made of galvanized steel or European tiles, are no exception. They are made of the same material as the roof covering, this can be called an advantage, while their inability to retain a large amount of snow is a minus.
Consumer reviews on the features of the choice of snow retention
The maximum slope angle for soft roofing can not be more than 15 °, such roofs are shallow, therefore, dangerous convergence of snow from them is quite rare. This indicates that the installation of snow retainers in this case will not be too complicated. Among other things, a good reason to reduce the power of snow stops is the roughness of the soft coating. According to customers: the rougher the surface is, the slope angle will be less, therefore, the risk of converging snow is reduced.
Installation of snow retainers is accompanied by many advantages. These designs, as users emphasize, provide uniform melting of precipitation. The convergence of the avalanche is practically excluded, among other things, the load of solid precipitation will be well distributed throughout the area. If we talk about the shortcomings, then these designs do not have them. And if some parts of the roof will be damaged by the convergence of snow, then the snow retainers were installed unprofessionally.
Snow Retention Technology
In a large assortment, snow stores on the roof are presented in stores today, the installation features of these structures will be mentioned below. However, if you are not sure that you can cope with the work yourself, it is best to contact specialists. For example, hooks can only be installed at the overlap stage, but not after. The design involves fixing under the coating itself, otherwise the system will not be able to hold snow. Hooks are not installed on the finished surface, since additionally it is necessary to carry out roofing.
It is advisable to design the works even at the stage of building construction or in the process of overlapping, as well as roof repair. If you decide to install snow retainers on a metal tile, then the lattice structures will be the best solution, this method is the most effective and simple. Such a snow stop system will be able to hold pieces of ice and snow. The lattice barrier copes with heavy snow, if you choose the right structural elements. Using suspended supports or nailed elements, the metal grill must be installed directly to the edge of the roof. The roof covering does not matter, it is quite possible to install a snow stop of this type on any roof.
Installation recommendations
Features of the installation of snow retainers consist in the fact that the suspension supports are hooks that do not need to be screwed on. They must be fixed to the crate, while the nailed supports are installed in the rafters, most often this is done on a soft roof. If we are talking about lamellar snow retainers, then they are the budget version, although they are made of a material similar to the roofing. Reliable protection with the help of these inexpensive devices cannot be achieved, among other things, their use on roofs whose slope exceeds 30 ° is unjustified.
Tubular installation
Installation of snow retainers of a tubular design provides for the implementation of a certain algorithm, it involves marking, according to which the supporting brackets will be installed. In this case, a punch should be used, with which it will be possible to form holes, self-tapping screws are installed in them. Snow retainer pipes are mounted in the holes of the bracket. In order to make the length suitable, the elements are joined together, while one-way crimping must be used. Joints are bolted. Similar actions should be carried out on each side of the building along the entire perimeter. Finally, the bolted connection is checked.
Installation of snow retainers on a metal tile and a professional flooring
If the installation of snow retainers will be carried out on the above-mentioned coatings, then fences should be formed that are installed on the supporting crate. They are fixed to the end, for this you should use screws 8x50 mm. In order to ensure a higher density of fasteners and reliability, the holes should be sealed with rubber. The optimum distance between the fasteners should be chosen depending on the slope of the ramp and the length. This parameter can vary from 0.5 to 1 m.
Conclusion
Do-it-yourself snow retainers can also be installed on the seam roof. To do this, a counter element is installed, and the snow retainer itself is attached to the base using hexagonal bolts with dimensions of 8x25 mm. The fastening must be installed in those places where the crate is solid.
