How Do Roof Snow Guards Work

Prevent Crushing Snow Slides from a Metal Roof – A.B. Martin

During a snowstorm, snow is deposited on rooftops and accumulates, creating what is called a snowpack. As the snow continues to pile on, the roof may be able to keep the snowpack on roof for a time, but as temperatures rise the suns rays will warm the snow and cause the snowpack to loosen. When this happens, gravity plays a role and the entire sheet of snow or ice is suddenly released and an avalanche occurs.

Installing snow guards on a sloped roof hold the ice and snow on the roof and prevent them from sliding off suddenly. The weight of the snow and ice is evenly distributed by the roof snow guards as it melts off and therefore preventing damage. This is not only important for public buildings but for residential properties as well.

Do Metal Roofing Snow Guards Cause Snow Dams

Snow guards never cause ice dams. They help hold snow and ice in position to prevent them from falling. Ice dams occur when snow and ice melt during the daytime due to the sun. It then refreezes before it can fall off when the temperatures drop at night.

This mainly occurs in older homes whose insulation is not efficient. At the drip edge, the snow will refreeze and cause water to move back up, penetrating the roof. This problem is rarely experienced in modern homes since good insulation eliminates this issue.

Large Profile Snow Guards

Large-profile snow guards have a pad face that is more than 4 square inches and acts more as a barrier to snow movement. Some large-profile snow guards may have over 15 square inches of pad faces. These snow guards are generally installed in a slightly staggered row or a row about 12 from the eave edge.

Additional rows may be necessary for steeper pitches or steel roofing systems with extended eaves to peak dimensions and roofs with higher maximum snow loads. Fewer guards are needed to regulate snow when compared to small profile snow guards.

A number of factors are important when designing and installing your metal roof snow guard system, to help you ensure the longevity of your metal roof.

  • Snow fall: the amount of precipitation and expected snowfall is important in considering what types and how many snow guards you need to install. How much snow does your roof typically see? How heavy is it?
  • Slope: A steeper roof surface will require additional installation of snow guards
  • Fastening: How your snow guards are fastened to your metal roof will determine how many are needed, and how often they will need to be replaced or repaired.
  • Type of snow guard: Once youve identified what type of snow guard you need, youll need to determine what size and brand will work best for your roof.

The installation will depend on your unique roofing needs, but generally snow guards are installed in multiple rows and staggered about six inches apart from each other, and six inches from the bottom and edges of the roof. This will ensure proper coverage of your metal roof to prevent large deposits of ice and snow from forming and falling off.

Avalanche: Tool Remove Snow From Your Roof While On The Ground

Installing metal roof ice guards on metal roofs is the best way to ensure an avalanche does not occur after snow or icy conditions. This is particularly important in places where heavy snowfall occurs during winters.

One of the challenges with installing snow guards on metal roofs is that most metal roof systems allow the metal panes to float freely above the underlying roof deck off raining. This is done so that the metal panes can expand and contract at a different rate than the underlying structure beneath them. So if you attach a snow guard onto a metal roof by driving fasteners through the metal panels, they will lose their ability to float and will allow for leaks to develop.

Its important when installing metal roof snow guards to use non-penetrating adhesive metal roof snow stoppers, where polycarbonate cleats are applied to the metal panels using a peel-and-stick adhesive rather than drilling in metal fasteners. When this is done correctly, the cleats will stop snowpacks from breaking apart suddenly and falling to the ground.

What Is A Snow Guard On A Metal Roof

Snow guards, also known as snow retention systems or snow brakes, are devices that regulate the snow that falls off your roof in order to help avoid snow avalanches. The guards hold the snow so it can completely melt first and then control the speed and amount of snow that comes off the roof at one time.

Unfortunately, winter weather brings the chance of damage to a home occurring. However, a snow avalanche could make that damage extremely dangerous. If a heavy snowfall melts and falls off a roof all at once, a rooftop avalanche could be a serious hazard by falling on any people or personal property that are below. In a less severe scenario, it could cause damage to gutters, skylights, or other parts of the roof. In order to avoid these problems, a snow retention system is an easy solution.

How To Install Snow Breaks On Metal Roof Panels

A snow break is attached to a metal roofs surface through adhering with a liquid adhesive, tape, mechanically with screws, or with clamps. Depending on the style of snow break you get, you will want to refer to the instructions and installation guides provided by the manufacturer.

When installing snow breaks, remember to position them on the lower half of the roof. You will typically place them in a single line or multiple rows, depending on the type of snow break you get. One thing to keep in mind when installing snow breaks is ensuring the overall spacing of snow breaks on the roof is done properly. If the breaks are not spaced equally or in a pattern to equally distribute the snow, the ice and snow may shift suddenly and create a snow avalanche.

Pro tip: Its a good idea to get snow breaks for metal roofs installed before the snowy season hits. Many people either manually install or schedule installations in the late spring or summer so they can be prepared for the fall and winter seasons.

Tubular type proved to me the most efficient snow stoppers. They consist of tubes with a diameter of about 1 inch. The installation process is pretty simple and straight-forward: the pipes are installed in two rows along the ramp, so that a barrier is formed that divides the snow mass into plates-looking fragments. As a result, chopped snow falls to the ground in small portions that are not dangerous.

The construction consists of several pipes installed parallel along the roof using the brackets with holes of the corresponding diameter. In the process of installation the specialists use holding devices and roofing screws. Installation is carried out using weather-resistant rubber gaskets, all elements are fastened with bolts and plates designed for metal roofing. You should not fasten the snow device only to one sheet without fixing it to the crate, the snow retainer will simply tear off.

In some cases, it is possible to install snow guards not along the entire perimeter of the roof, but in certain places: above entrances, parking, a terrace and over attic windows

S Of Stopping Snow From Sliding Off Metal Roof

Protecting Metal Roofs with STINGER® Mini SnowGuardâ¢

Method 01: Using Snow Guards

Snow guards are arguably one of the best options to stop snow from sliding off. These generally consist of pieces of metals in a slightly upward angle.

However, they have to be installed in numbers. These can hold snow from sliding off the roof.

It is necessary to keep in mind that snow guards do not completely stop snow from sliding off. Rather, these allow only a small amount of snow to slide off the roof at once.

There are more positives to using snow guards. And there are a lot of snow guards in the market that can be installed with the help of adhesive. This releases you from the pain of drilling holes in the metal roof.

Method 02: Using Snow Fences

Generally, snow fences are installed near the edge of the metal roofs. If you have constructed your roof in such a method that you cannot install snow guards, using snow fences will surely save you.

Snow fences are like metal fences but some inches higher. Most importantly, they can be used if snow guards arent effective on your roof.

Snow fences can hold off a huge amount of snow. These are especially operative against snow avalanches.

Method 03: Using Snow Diverters

Snow diverters are angular pieces of metal. In fact, snow diverters are metal structures angular in shape.

They divide the sliding snow and direct these around pipes, chimneys, and similar types of roofing structures. By diverting the snow, they also prevent snow buildup and damage to the metal roof.

Snow Guards: Are They Necessary On A Metal Roof

Snow guards: Are they necessary on a Metal Roof?

A question that we get asked a lot, is if it is really necessary to install snow guards on a metal roof. The short answer is that it depends where you live. Lets unpack some of the information regarding snow guards.

What is the purpose:

The purpose of snow guards is to hold accumulated snow on the roof, until it can slowly melt. Lets say that you live in a area that receives 4-6 inches of snowfall regularly. The snow can build up on your roof throughout the winter until there is 12 or more accumulated. As the weather begins to warm, this accumulated snow can slide off the roof in large chucks, causing possible damage to gutters and personnel. If snow guards are installed, they prevent the snow from sliding, until it has a chance to melt.

What Damage can be Caused:

Depending on the situation, and the severity of the winter, the lack of snow guards can cause a lot of damage. Sliding snow and Ice can tear gutters off of your home, requiring new gutters to be installed. Chunks of snow can also slide off at the most inopportune times,inuring anyone that happens to be standing in its way. The last thing that you need is to have someone suing you because of being injured by sliding Snow and Ice.

What options of Snow Guards are available:

In Summary:

Be sure to give us a call if you have any question concerning your roof, and we will do our best to answer them for you.

Which Ice Retention System Is Right For Me

Ice retention systems are engineered for all sorts of roof types and weather conditions. That means that some retention systems will be more suited to shingle roofs in moderate weather, while others will be specially designed for metal roofs and freezing weather. It all comes down to the anticipated weight of the snow and ice on the roof, as well as the failure point of the snow guard. While some homeowners are comfortable making such calculations on their own, it might also help to call a professional inspection service to get an expert recommendation
