Tubular snow retainer: types, structural features, installation instructions

Tubular snow retainers are essential for shielding your roof from the elements during the winter. These tools are made expressly to stop snow and ice accumulation on roofs, which can endanger people’s safety and cause structural damage. There are many varieties of tubular snow retainers, and they are renowned for their strong build and efficient functionality.

Tubular snow retainers are typically installed along the edges of roofs to hold snow in place. They are typically made of sturdy materials like plastic or metal. They function by erecting obstacles that stop big snowdrifts from falling off the roof all at once, lowering the possibility of unexpected avalanches. This safeguards not just the roof but also the area surrounding the structure, since snow and ice falling from the sky can seriously injure those below.

Depending on the type and manufacturer, tubular snow retainers have different structural characteristics. Common designs include interlocking component systems for added stability and cylindrical tubes with ridges or bars to help grip the snow. Certain retainers have mechanisms that can be adjusted to accommodate varying snow loads and roof pitches, which makes them adaptable to different roofing configurations.

It takes careful planning and adherence to manufacturer instructions to install tubular snow retainers. Usually, they are positioned at regular intervals to ensure uniform snow distribution along the roof’s eaves and edges. When the retainers are installed correctly, the snow can be retained without endangering the roof’s integrity or causing damage to the surface.

Understanding the different types, structural characteristics, and installation of tubular snow retainers is crucial for homeowners and building managers in snowy climates to preserve roof safety and extend the life of roofing materials. You can minimise the risks associated with winter weather and effectively manage snow accumulation by selecting the appropriate type of snow retainer and making sure it is installed correctly.

When are such snow retainers?

More precisely, the SNiP section is painted with the loads and effects on the roof. Here, the amount of snow cover and the pressure it exerts determine the zoning of our nation’s territory.

The fact that loose, wet snow puts an even greater strain on the roof’s rafter system is a significant selling point for businesses that provide services for clearing snow off residential roofs. Indeed, this argument is valid because, although loose snow has a density of only 10 to 100 kg/m3, by the end of winter, it can reach 280 kg! Increase the density of snow, water, and raw spring water vapor, and the effect on the rafters of the roof itself is already up to 700 kg/m^.

Why does wet snow get so thick? Everything revolves around the physical process—such as snow fermentation—that occurs when ice crystals condense into airborne snowflakes. Because there are ice crystals present in wet snow, it is already in the three-phase stage of fermentation, whereas dry snow is only in the second phase. Furthermore, the structure and variations in the seal directly affect how much weight the snow cap on the roof has. Thus, in a Russian winter, the amount of loose snow drops from 98% to 20%.

As a result, if your home is skillfully designed and the roof’s bearing is intended to withstand the typical snow load in your area, it is best to simply use snow retainers to keep the snow from sliding off the roof, as doing so may occasionally be impossible. Furthermore, we can only sympathize with you if the house’s roof was built without consideration for seasonal loads and monthly cleaning during the winter.

A two-pipe snow holder is thought to be the most efficient in certain situations. In severe snowfall, a regular corner may even bend, particularly if there is damp snow on the roof. Additionally, the tubular snow holders are beneficial because they split the snow mass in two or more directions, preventing any potential hazards to people or their property. For this reason, knowledgeable engineers typically advise using specific pipe snow retainers. And installing them is limited to the area above the attic windows and around the roof’s perimeter, which is not too difficult:

As you can see, tubular snow retainers have just two rows of metal pipes that are fastened to rafters or a crate, giving them a first-look similarity to cornices. In actuality, though, this design lets you keep a good amount of snow cover. This is why a lot of experts think that the only snow retention system that is actually safe in Russian winters is the tubular design.

Crushing a big snow mass into smaller pieces is the job of tubular snow retainers. As a result, the sliding snow’s so-called kinetic energy dramatically drops, as does its destructive effect. Consequently, up to two tasks are resolved simultaneously: the snow is eliminated by the force of its own mass and becomes considerably less hazardous and harmful when it falls. Is there anything better?

Structural features

It is essential to install a snow retention system on a roof with a slippery coating. We are referring to metal roofing materials like metal tiles, corrugated board, and folding roofs. In this instance, tubular brackets are the best option. It is safer and more accurate to cut the snow into small portions rather than accumulating large amounts on the roof. Additionally, as the snow melts, a film of water forms beneath it, which it can already glide over.

Two pipes are fastened in parallel to the roof’s edge using specialized brackets to form tubular snow retainers. For the roof of the house, tubular snow retainers are typically made of galvanized painted steel; copper or aluminum are used less frequently. And there are two species of these snow retainers in turn:

  1. The first is from hollow pipes, diameter, which are from 3 to 4 and centimeters and, which is mounted on supports in two rows.
  2. The second – flat -oval pipes, with a diameter of 40×20 millimeters or 45×25 millimeters. For such, there are special supports that are universal for any type of roof. Installed in one or more rows.

They all have the same appearance:

How to choose a good snow retainer?

The strength and load-bearing capacity of the profile pipes, the steel thickness, and the brackets determine every aspect of these roofing components. In an ideal world, these snow retainers would be made of galvanized steel coated with a polymer to prevent corrosion and lengthen their useful life. Additionally, the oval shape of the pipe is the strongest.

However, as the market for snow retention systems has grown, many low-quality products have emerged. These snow holders are made at a very low cost, but their quality and longevity are rarely satisfactory. Since selecting a high-quality, long-lasting tubular snowfield that can handle its intended uses? We arranged everything for your convenience in points:

  • Paragraph 1. The first thing you need to pay attention to is the quality and thickness of the steel. It is these parameters that ensure the strength characteristics of the snow retainers and their bearing abilities. So, in modern products a variety of steel brands and its thickness are used.
  • Point 2. The second point is the quality and thickness of the zinc layer, the method of applying it to the products is cold or hot. For example, hot zinc, which is already made for finished products, is considered more durable, and as a result, the layer turns out several times thicker. True, sometimes tubular snow retainers are made already of galvanized steel, as an alternative option, but when processing and assembling (for example, with a bend) there are places without zinc or with its very thin layer, and this can further lead to corrosion.
  • Point 3. The quality of the dyeing of the snow retainer is also important. Paints and type of application determine the appearance of the product and its durability. It is important that both the zinc and the metal layer are constantly protected from the effects of the external atmosphere. Remember that such roofing elements by the genus of their service are constantly dealing with moisture, and therefore even a random scratch quickly becomes the cause of corrosion.
  • Clause 4. And finally, you must pay special attention to the possible simplification of the configuration of the product. If any snow retainer has fewer details and devices than analogues, this does not speak about the genius of the engineer-this indicates a reduction in production. And in the end, all this is a deterioration in the strength characteristics.
  • Clause 5. There are still such strange sets in the construction market, in which only four supports are offered on a three -meter segment of the snowman. The installation step in this case will be only 80-90 centimeters. Yes, on small slopes, such a kit can be mounted without special consequences, but on longer ones – these are problems. For comparison, in the same Europe, the maximum installation step for the most durable supports is only 70 centimeters.

What helpful advice! Regarding the selection of the film by the snow retainer manufacturers, the best reviews available today are for the foreign brands Borge and Orima. Although the company "Rus" makes snow retainers that are quite similar to the original, there are also versions available on the market. However, the thickness and quality of the pipes and brackets themselves have frequently been criticized in reviews.

We explore tubular snow retainers in this article for "All about the roof," including their types, construction methods, and installation techniques. These tools are essential for controlling roof-mounted snow accumulation and averting hazardous slides and damage. We’ll examine various designs and their unique characteristics to help you decide which might work best for your roof. You can install these retainers safely and effectively on your own or with professional assistance thanks to step-by-step installation instructions that will walk you through the process. Knowing tubular snow retainers is crucial for keeping a safe and secure roof during snowy seasons, whether you’re a homeowner or a roofer.

Step -by -step installation instructions

Tubular snow retainers are widely regarded as the most durable design. They are typically utilized on roofs that have a smooth surface, a large area of slopes, and a strong slope:

Nonetheless, in order to obtain a trustworthy outcome, it is crucial to follow all guidelines exactly.

We plan the location and number of snow retainers

Prior to beginning the snow holder installation, you need to create a plan or scheme. In any event, since every support has a maximum, the loads must be determined.

If you have done all of your calculations ahead of time and created a thorough plan, you shouldn’t run into any issues when installing the snow holders. Ideally, you won’t run out of fasteners or have too many of them:

Thus, as soon as you know the snow pressure value, you can determine how much you can withstand a particular support and then figure out how many of those are required for a particular roof area.

We calculate the distance between the supports

The snow load in a particular area should be taken into consideration when determining the standard distance between the support brackets. Ultimately, it is critical that the weight from the snow retainers be distributed to the capital structures, or the supporting walls. If this isn’t the case, the snow on the overhangs could damage the roof’s structural integrity by acting on the "effort of the lever" mechanism.

The roof is completely encircled by tubular snow retainers that are installed without interruption. Increase the number of rows of these snow retainers to two or three, without interfering with them, and make sure that they are at least two meters apart, if the roof slopes are longer than five and a half meters.

In order to ensure that all snow falls only on the portion of the roof that is higher than the cornice, snow holders for metal roofs should be installed at the same level as the load-bearing walls. The load-bearing wall should be directly above the cornice overhang at a distance of 60 to 100 centimeters. Make sure the attic windows have snow retainers above them. An uninterrupted crate is ideal when using tubular snow retainers above them.

Using fasteners and adapters for such snow retainers, the number of pipes and rows can be changed. However, bear in mind that snow pressure is evenly distributed on fasteners, so the roofing material itself needs to be strong enough to support this weight. Consequently, the step needs to be put 120 centimeters in. The step should be 90 centimeters if the roof slope is greater than 5400 centimeters, and up to 60 centimeters if the slope is greater than 1260 centimeters but less than 5400.

Additionally, a two-pipe snow retainer must be installed in a home with a snow load of 180 kg per square meter and a roof tilt of 30 degrees.

Correctly fasten the brackets

The tubular snow holder brackets on roofs made of metal tiles, corrugated board, or ondulin are exclusively fastened to the crate. In the event that bituminous tiles are being discussed, then the OSB’s surface. Additionally, you will require a support unit if you install a snow retention system for ceramic tiles:

Here is a helpful, in-depth video that demonstrates how to install these kinds of snow retainers:

Expanding the roof’s crate at the expense of the bars where the snow retainers are fastened is a wise move. They must be installed through the roofing directly, utilizing metal-wreck screws and a hermetic rubber gasket.

We understand the brackets

There are brackets available for tubular snow detectors with an ideal, straightforward design. In order to allow him to grab onto the wave of metal tiles, the second type of bracket has a tiny bend in its base. In a sense, unique seals spring this bracket:

The bracket’s extreme supports are installed first. The snow retainer’s free end shouldn’t protrude farther than 10 centimeters. Try on holders next, having already put on the brackets.

The intermediate mount will be put in place by us. It is preferable to avoid doing this beforehand to ensure that none of the brackets end up not matching the roof hole that was made. However, wet snow will rip this bracket off along with the contents on the roof if snow retainers are only fastened to the coating and not to the crate.

Type Structural Features, Installation Instructions
Tubular These retainers are cylindrical in shape, designed to prevent snow from sliding off roofs. They are typically made of durable materials like metal or plastic. Installation involves securing them along the roof edge, ensuring they are evenly spaced to support the weight of accumulated snow. It"s important to follow manufacturer guidelines for proper installation to maximize effectiveness.

It’s important to comprehend the types and structural characteristics of tubular snow retainers if you’re thinking about installing them on your roof. These gadgets are meant to stop snow from unexpectedly sliding off your roof, which could endanger people below and cause property damage. Although they are made in many different styles, they usually consist of strategically positioned cylindrical tubes or bars along the roofline.

Installing a tubular snow retainer usually entails fastening it straight to the roof. Depending on the kind, mounting options for them include adhesive, clamps, or screws to keep them securely in place in snowy environments. Since the effectiveness of these devices depends on their secure attachment, it’s critical to follow manufacturer instructions and possibly seek professional assistance to ensure proper installation.

The capacity of tubular snow retainers to more evenly distribute the weight of accumulated snow across the roof is one of its main benefits. This aids in preventing the accumulation of big, heavy snowdumps that might endanger public safety or possibly cause structural damage. These devices lessen the chance of unexpected avalanches off the roof by preventing snow from melting too quickly by retaining snow in place.

Think about things like the slope of your roof, the local climate, and the retainer’s particular design when selecting a tubular snow retainer. Certain designs might work better on sloped roofs, while others might work better on flat roofs. To prevent corrosion or damage over time, make sure the retainer’s materials are appropriate for the type of roof you have.

In the end, adding a tubular snow retainer to your roof is a proactive roof maintenance measure that can improve security and safeguard your property. These devices prolong the life of your roof and lessen the frequency of snow removal by averting unexpected snow slides. Choosing the proper type and installing them correctly ensures peace of mind during snowy weather, whether you’re installing them on a residential or commercial building.
