Homeowners with Onduline roofs confront particular difficulties when winter arrives, particularly with regard to snow accumulation. Made from organic fibers impregnated with bitumen, Onduline is a lightweight roofing material that is well-known for its affordability and longevity. But because of its smooth surface, snow can slide off easily, endangering people and property below. Here’s where snow holders—also called snow guards or snow stops—come into play.
Snow holders are little objects that are placed strategically on roofs to stop large, dangerous sheets of snow from sliding off. Installing snow holders is especially crucial for Onduline roofs, as their slick surface makes them susceptible to snow shedding. In order to prevent an all-out avalanche, these devices function by generating friction or barriers that keep accumulated snow in place until it melts or safely releases in smaller amounts.
Pitch of the roof, weather, and personal taste are all important considerations when selecting snow holders for Onduline roofs. Snow guards are typically made of rubber, plastic, or metal and come in a variety of forms and styles. Common varieties include pipe, fence, and pad guards; each has a special benefit based on the structure of the roof and the anticipated snow load.
The efficacy of snow holders depends on proper installation. Usually, they are put in a pattern that effectively manages snow retention while maintaining the integrity of the roof. In addition to their practical uses, snow holders can improve a roof’s aesthetic appeal by providing a personalized appearance that blends in with the Onduline roofing system’s overall style.

Features of fastening snow retainers on the roof of ondulin
Many problems arise when snow slides off the roof, including broken snowdrifts that damage parked cars and plantations and seriously hurt the owners. The snow retainers on the roof are unique safety features that stop snow from sliding off it.
Snow detainee installation is governed by joint venture 17.13330.2011 "Roof" under SNiP II-26-76. Roofs equipped with snow retention systems have a slope of greater than 3 degrees (5%). Attached to the crate, runs, and bearing roof structures are snow-holding devices. The system’s components are positioned above the load-bearing walls, above the attic windows, and in other locations, between 60 and 100 cm from the cornice overhang.
Snow retainers come in two varieties: passing and non-transmitting. Lattice, tubular, and tubellous (point) structures are included in the first category. Ondulin does not have the second type—snow "logs" and strips—installed.
Installation of snow retainers on a roof from Ondulin
Because snow holders from different manufacturers can differ in useful ways, we will take into account the general guidelines for installing them.
Installing an extra crate in the locations where the elements are fastened is made possible by the fact that installing the snow retention system is typically done in conjunction with roof repair.
2. There are two possible ways to fasten the tubular snow retention system during installation:
– It is best to use brackets with a mortgage plate. The integrity of the roof is not compromised because it is fastened directly to the crate and covered with an ondulin sheet. The brackets are affixed to the bottom of Ondulin’s waves;
– Waterproofing gaskets must be used when using regular brackets. The bracket is fastened with two 8×50 mm screws and placed in the Ondulin wave’s lower portion.
The manufacturer’s instructions should be followed to determine the cross-section of the snow-contaminating elements, the quantity of brackets, and the location of their installation.
3. Ethnic snow retainers hold large amounts of snow and are more effective than tubular ones. Similar to tubular snow retainers, lattice snow retainers are mounted.
The roof fence and the lattice snow retainer system are frequently paired together.
4. In areas with little snowfall, bulbous snow holders are added to tubular or lattice systems. Ondulin waves have components installed in their lower portion.
The following sheet is placed on top of the embedded element plate, which is fastened to the crate directly.
When a solid crate is present, components for the finished coating may be installed. Rubber seals are used to insulate the fastening locations.
According to the manufacturer’s instructions, decide how many cupboard snow-retention elements to use and where to put them.
Snow building up on the roof can be advantageous for the house’s insulation as well as a potential source of trouble, such as sidewalks suddenly collapsing. The roof has snow retainers, which are unique security features, to hold it in place. How can I correctly install elements on Ondulin?
Snow holder for Ondulin
Holder of snow for Ondulin
A snow holder is a dependable assurance that snow that has been covered by the house’s roof won’t put additional strain on the roof’s perimeter or cause an avalanche of snow and ice to slide down, endangering people, animals, and nearby property (mostly, cars parked close to houses and other expensive cars and objects can suffer).
The snow retainer shields the drainage system as well because it breaks up the snow mass into smaller pieces by delaying the snowy, converging flows. This allows the snow to have a higher mass, meaning that the snow falling from the roof has less shock force.

Snow holders made especially for Ondulin roofing contribute to long-term roof integrity maintenance in addition to improving safety by keeping accumulated snow firmly in place. The significance of these devices, their successful use with Ondulin roofing materials, and installation considerations that guarantee optimum performance and durability throughout the winter months are all covered in this article."
How to choose snow retainers for the roof
In order to select the appropriate snow holders, you must be aware of the following:
Which kinds of snow holders are ideal for your home’s roof in particular
– How to determine the precise quantity of snow retainers needed
– In the end, we select the manufacturer of our choice, keeping in mind the features and costs of the goods.
A brief review of the types of snow retainers
Understanding the various kinds of snow retainers available on the market is crucial when selecting one. Think about them.
Mesh snow holders for the roof: These are safety features made up of two, three, or four brackets fastened to the roof, and a metal grate or plate shaped like a mesh. A snowman of this kind is typically 2.5 meters long and 15 centimeters tall.
Mesh snow retainers are typically placed on country homes’ tiled roofs and the rooftops of tall buildings.
Naturally, such detrusters won’t be able to hold the entire snow mass that can build up on the roof’s slope and reach impressive sizes. At that point, the safety features—including the gutters and cornice bar—may be torn off.
It is preferable to duplicate the lattice snow holders in order to avoid this, either by adding more rows of mesh snowmen or by using different kinds of snow holders, like tubular or point snowmobiles.
As implied by the name, a tubular snow retainer consists of two oblong or round tubes that are fastened to the roof with brackets.
The typical spacing between the brackets is between 70 and 110 cm.
Compared to their round counterparts, oval tubes are more resilient. It’s also important to consider the steel bracket and tube properties, which include neocynching, galvanizing, and galvanizing with colored polymer coating, when selecting tubular snow retainers.
It is reasonable to say that the most dependable way to stop an avalanche from the roof is to use tubular snow holders.
By design, tubular snow retainers, as they are called, crush snow mass by allowing it to pass between the tubes and the roof’s surface. Consequently, the snow is removed from the roof in pieces that are nearly harmless and have lost their initial destructive energy.
Snow retainers on plates and corners
Composed of polymer-coated sheet steel that gives you the flexibility to select the best option based on the roof’s shade
The inadequate strength level of these models is a drawback. They should not be used with a slope of less than thirty degrees because they are unable to support a sizable amount of snow.
Point snowmobiles: These are snowmobiles with bent hooks made of metal that are intended to hold small amounts of snow. These snowfields are found in a checkerboard-patterned row or rows. It is advised to install snowfields across the whole surface of a roof when it has a sizable area and a fairly steep slope.
Steps on snow from the polycortonal
A brand-new, extremely durable plastic point snowfield has entered the market in recent years. These snowfields work on the same principle as metal, but they are made of a different material and have a more contemporary look.
Polycarbonate snowsteppers, in spite of their seemingly delicate appearance, are actually fairly sturdy pieces. Producer: Borge.
Despite its humorous nature, the log that is securely fastened to the roof will serve as an excellent snow retainer.
Because log snow retainers can maintain much larger snow layers than their other analogues, they are typically used for solid buildings with a strong crate that can withstand a large mass of snow.
The snow retainer works on a similar principle to mesh or tubular detenters; the main distinction is that it is not prone to deformation.
The log’s hooks ought to be securely fastened to the roof!
The choice of a snow retainer depending on the type of roof
Now that we know the basic varieties of snow retainers, let’s determine which kinds are best suited for the different kinds of roofing coatings.
Holders for snow on metal tiles
It is advised to use either tubular snow holders or the more costly mesh snow retainers for roofs composed of metal tiles.
It is crucial to accurately calculate the load that these kinds of snow retainers will be subjected to when installing them on metal roofs; otherwise, snow from the roof may fall along with safety components and roof fragments.
The recommended minimum intervals between the rows of snow retainers vary depending on the roof’s angle of inclination and the snow category that applies to this area.
How to store snow on a roof that is mild
Point snowstorms or tubular snow retainers are used on bitumen tile roofs.
Generally speaking, flexible tile roofs have a unique rough surface that is coated in crumbs from basalt rocks, which has no effect on the snow avalanche. As a result, compared to metal roofs, soft roofs are subject to lower safety element requirements.
Point snowstorms are typically placed on soft roofs. Although their ability to deflect snow is usually sufficient, some believe that flexible tiles work better when combined with snowfields, particularly if the tiles are made of transparent, ultra-strength plastic (Borge). The folks who make the bitumen tiles themselves agree with us.
Rooftop holders from Ondulin
Not many homeowners who have their homes covered in Ondulin consider installing snow retainers.
Ondulin is among the safest places in terms of "snow avalanches." A rough coating and even the caps of roofing self-tapping screws help to retain snow.
Ondulin still occasionally has to have snow holders installed, though.
Installing tubular snow retainers with mortgage plate mounts is an option in this situation.
Holders for snow on the folding roof
With one minor exception—their capacity to support large loads—falst roofs are comparable to metal tiles.
For folding roofs, tubular snow retainers or mesh snow retention are recommended. The only things that set these snow retainers apart from their metal roof equivalents are the specialized fasteners.
Ceramic tile snow holders
When it comes to traditional ceramic tiles, mesh snow retainers work best because, in an emergency, they can hold both snow and, if necessary, tile fragments. Tubular snow retainers are still utilized for piece tiles, though, because they are less expensive.
Piece tile snow retainers also feature unique fasteners; these are the only features that set this type of snow retainer apart from similar ones.
We calculate the number of snow retainers necessary for your roof
The next stage in selecting snow retainers is figuring out how many are needed, keeping in mind the kind of roof you have, the size of the slope’s angle, and the roof’s length.
We provide an example of how to calculate tubular-type snow retainers.
The following measurements are needed for the calculation:
1. Depending on the length of the roof slope, the angle of inclination, and the classification of the snow region, determine the number of rows of snow retainers. (Moscow is located in the third area with snowfall.)
Angle of roof tilt, º
The Moscow region’s slope’s length, in millimeters
III district of Sneakovy
Metric distance, mm, between brackets
For instance, if the roof has a 35 degree inclination, there shouldn’t be more than 7.2 meters between the rows of snow retainers. This is contingent upon installing the bracket supports 800 millimeters apart and 5.2 meters apart when installing them 1100 millimeters apart.
Intriguingly, you must install two rows of snow retainers on a roof with a slope length of 10 meters and an angle of inclination of 45 degrees.
2. The quantity of snow retainer rows ascertained. Next, we determine or take into account the total length of each row of snow retainers.
3. Determine how many more snow holder rows there are:
– Overhead ventilation pipes
– on higher roof levels
It is imperative that snow retainers be placed over the attic windows.
Generally speaking, anywhere there’s a chance of harm coming to your property, that of a stranger, or harm to the roof components.
4. After calculating the outcome, we figure out how many sets of snow retainers are needed and how much it will cost overall. (Typically, a set of tubular snow retainers is three meters long; however, some manufacturers also sell sets that are one meter long.)
This table is another useful tool to use when figuring out how many mesh snow holders you need.
Calculation estimate for point snow holders and snowfields
The following formula is used to determine the number of snowstorms:
1. Four snowfields are typically found in a row for every one linear meter of roof length.
The process of installing snowfields follows a checkerboard layout.
3. Using the following table, we calculate the necessary number of rows of snowfields based on the slope’s length and roof inclination angle.
The Moscow region’s snow load values are satisfied by the table data.
For instance, four rows of snowmobiles would need to be installed along a 10-meter ramp if the roof had a 45-degree inclination.
Taking the 12 m roof length in the skate, we obtain:
There are 384 snowfields on the whole roof, calculated as follows: 4 rows * 4 snowfields per meter * 12 meters * 2 (two roof slopes).
You need only select the manufacturer if you know what kind of snow retainer is best for your roof and how many sets or snowfields are needed.
How can you pick a snow retainer that works well for your home’s roof? suggestions for selecting the type and manufacturer of roofing snow catchers. Guidelines and examples for figuring out how many snow holders are needed.
Your Onduline roof’s longevity and winter safety can be greatly increased by adding a snow holder. Even though onduline roofs are lightweight and resistant to weather, heavy snow accumulation can still cause problems. Snow holders, sometimes referred to as snow guards or snow stops, assist in preventing snow from unexpectedly sliding off the roof, which can endanger people and property below.
Since snow tends to accumulate and slide along the lower edge of the roof, these devices are usually placed strategically there. Snow holders lessen the chance of unexpected avalanches by forming tiny barriers or holding pockets that permit snow to melt and progressively release in smaller quantities. This keeps large chunks of snow from falling unexpectedly, protecting not only your roof from possible damage but also the safety of those around your house or building.
It’s crucial to select the appropriate kind and guarantee correct installation when thinking about adding a snow holder to your Onduline roof. There are various styles and materials to choose from, such as plastic, metal, or even holders that are specifically made to work with Onduline. The orientation and distance between these holders are determined by elements including the pitch of the roof, the local climate, and the average annual snowfall.
All things considered, adding a snow holder to your Onduline roof is a preventative step that increases its lifespan and safety. You can safeguard peace of mind throughout the winter months and safeguard your investment in the roof by avoiding snow build-up and sudden releases. To ensure optimal performance and safety for many years to come, consider speaking with a roofing professional to determine the best snow holder solution for your particular roof and climate.
