Every winter, snow suddenly falling from rooftops causes trouble and sometimes accidents. It injures people and also damages property. This could have been avoided if the building owners had installed snow guards on the roof.
Basic constructions of snow stops
Installation of snow retainers must be carried out only after choosing a suitable design. Among others, one can distinguish a lattice variety, which looks like brackets rigidly fixed on the roof, between them there are lattice compartments. Such structures are made from rectangular corners, as well as pipes and frames. Crossbars act as reinforcement. If it is necessary to lengthen the structure, shorter sections must be joined together.
Snow guards on the roof, the types of which are described in the article, can be tubular. In this type, the brackets are fixed to the roof sheathing or rafters. Through thempassing metal pipes. Depending on the distance between the pipes and the space between the bottom pipe and the roof, it will be determined how much snow the device can hold. If it is known that the structure must be more powerful, then the strength can be increased by reducing the distance between the pipes.
For reference
Snow guards on the roof, the types of which can be very different, must evenly distribute the load of snow on the roof surface. In the case of tubular snow guards, their installation should be carried out along the line of the load-bearing wall.
Features of snow stops in the form of hooks and corners, as well as plate structures
Snowstop hooks are hooks that will not hold snow in a large volume, 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. Typically, hook-shaped snow guards are used as an addition to other similar devices.
Do-it-yourself installation of snow retainers can be done by any home craftsman, plate or corner structures that perform their function on metal roofs, as well as structures made of galvanized steel or euro tiles are no exception. They are made of the same material as the roofing, this can be called an advantage, while theirthe inability to hold a large amount of snow is a minus.
Consumer feedback on the features of choosing snow retainers
The maximum slope angle for soft roofing cannot be more than 15 °, such roofs are flat, so dangerous snow drift from them is quite rare. This indicates that the installation of snow retainers in this case will not be too difficult. Among other things, a good reason to reduce the power of snow stops is the roughness of the soft surface. According to buyers: the rougher the surface, the smaller the slope angle will be, therefore, the risk of snow drift is reduced.
Installation of snow retainers comes with many benefits. These designs, as emphasized by users, ensure uniform melting of precipitation. The descent of an avalanche is practically excluded, among other things, the load of solid precipitation will be well distributed over the entire area. If we talk about the shortcomings, then these designs do not have them. And if some parts of the roof are damaged when the snow melts, then the snow retainers were not professionally installed.
Technology for mounting snow guards
In a large assortment today, snow retainers on the roof are presented in stores, the installation features of these structures will be mentioned below. However, if you are not sure that you can cope with the work yourself, then it is best to contact specialists. For example,hooks can only be installed at the stage of overlapping, but not after that. 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, as additional roofing will have to be carried out.
It is advisable to design the work at the stage of building construction or in the process of overlapping, as well as repairing the roof. If you decide to install snow retainers on metal tiles, then 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 hanging supports or nailed elements, the metal grating should be installed directly to the edge of the roof. The roof covering does not matter, it is quite possible to install this type of snow stop on any roof.
Recommended installers
Features of the installation of snow retainers also lie in the fact that the suspension supports are hooks that do not need to be screwed. They must be fixed to the crate, while nailed supports are installed in the area of \u200b\u200bthe 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 roofing. Reliable protection with low-cost datadevices cannot be achieved, among other things, their use on roofs whose slope exceeds 30 ° is unjustified.
Installation of tubular structure
Installation of tubular snow retainers involves the implementation of a certain algorithm, it involves marking along which the support brackets will be installed. In this case, a puncher should be used, with which it will be possible to form holes, self-tapping screws are installed in them. Pipes of the snow retainer are attached to the holes of the bracket. In order to make the length suitable, the elements are joined together, while one-sided crimping must be used. The joints are reinforced with bolts. Similar actions should be carried out on each side of the building around the entire perimeter. Finally, the bolted connection is checked.
Installation of snow retainers on metal tiles and corrugated board
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 towards the end, for this you should use screws 8x50 mm. In order to ensure a higher fastener density and reliability, the holes should be sealed with rubber. The optimal distance between the fasteners must be selected depending on the slope of the ramp and the length. This parameter can vary from 0.5 to 1 m.
Conclusion
Do-it-yourself installation of snow retainers can also be carried out on a folded roof. For this, a counter element is installed, and the snow retainer itselfattached to the base with 8x25mm hex bolts. Fastening should be installed in those places where the crate is solid.
