Snow Retention The Invisible Code

Snow retention codes do not seem to be a priority in the United States’ roofing industry. But it is very common to see snow and ice sliding off of a metal roof’s slippery surface. Snow and ice crush cars, and damages the roof, gutters, and landscape.  In some cases, snow and ice cascading off roofs have killed people. Codes for snow retention systems are essential to protect people and property from sliding ice and snow.

There are many reasons snow retention systems fail and why we need codes in place.  Some examples are:

PRODUCT FAILURE

snow retention system

This snow retention system was not engineered for some variable of the project that caused it to fail.

The snow guard was not strong enough to hold the load it was carrying.

Anyone can cast a wax snow guard, spread some adhesive on the bottom, and tell the consumer how to install it without any testing of the product or the system. Codes would provide a standard to ensure adequately designed products are utilized.

SHEATHING/ROOFING MATERIAL FAILURE

Roofing material is inadequately secured for the shear created by sliding snow.

If the roofing material is not securely fastened to the deck (specifically on standing seam metal roofs), added weight can cause the standing seam metal roof to slide right off, along with the rest of the roofing material and snow retention system. There is a code requirement in place for wind uplift on standing seam metal roofs, but not for shear strength.

Screws or fasteners pull out.

sliding snow and ice

Sliding snow can be incredibly dangerous.

When installing snow retention on roof sheathing, the thickness and type of the sheathing determines the fastener pull-out strength.  If one is installing a snow retention system on 7/16-in. OSB board, the fastener will fail more quickly than when using ¾-in. plywood.  (See chart below.) When designing a layout for a project, many snow retention manufacturers do not test for these variations.  If the snow retention system was designed for ¾-in. plywood and the project is using 7/16-in. OSB board, the whole system needs to be redesigned.

The fastener does not penetrate the sheathing.

If the fastener/screw is not penetrating the sheathing, the snow guard will not have the holding strength for which it was designed.

 

 

ADHESIVE FAILURE

plastic snow guards

These plastic snow guards fell to the ground because the adhesive did not bond properly

When using an adhesive, if the surface is not free of dust, dirt, oil, or waterproofing; or it is not clean and dry, the adhesive will not adhere properly.
If the temperature is not above 50 degrees F, the sealant will not cure. If a load is placed on the snow guard before the 28-day cure time, the snow guard is more likely to fail. (This is according to the Technical Data Sheet  for SB-190)

SYSTEM FAILURE

The system is not designed for the roof slope and snow load.

When designing a snow retention system, factors change from project to project: the slope, roof type, sheathing type, and roof snow load.  If the snow retention system is not engineered for the variables of the project, it can fail.
Most snow guards are not tested to the fail point of the system.

Many snow guard manufacturers claim theirs are tested, and many of them are, but they are not tested to the fail point of the entire system.  The product may be tested to maintain its shape, but was it tested to stay on the roof?  It’s great if the product stays in one piece, but not if the fastener fails, the adhesive fails, and the sheathing fails.

snow retention code

A snow retention code needs to be put in place to help prevent injury to people and damage to property.

INSTALLATION FAILURE

The product was not installed to manufacturer’s specifications.

The manufacturer’s instructions need to be followed meticulously in order to ensure safety and to keep warranties in effect.  Many manufacturers have specific torque requirements, placement, and maintenance instructions.  If these instructions are not followed, the system can fail and the manufacturer is not at fault.

Obviously, there are valid reasons why the United States should establish codes for snow retention on roofs.  Why hasn’t this happened?  A few reasons could be:

  1. Snowfall occurs in certain areas of the country but not nationwide; therefore, the demand for codes is minimal.
  2. Not many deaths occur due to ice and snow sliding.
  3. Property damage is localized.
  4. The insurance industry is not pushing for this type of code.

There are many other codes in place to protect people and property; so why not for snow retention?  We have codes for wind uplift and ICC test standards for product failures due to wind and moisture penetrations, to name a few.  How many life threatening events need to occur before we do the right thing when it comes to a code for snow retention on roofs?

It’s time to make the invisible snow retention code visible.

Why Specify Snow Guard Retention

WHY SPECIFY SNOW GUARDS FOR SNOW RETENTION?

There are several factors that one must evaluate when determining if a particular building requires a snow guard retention system. During the winter months, as snow accumulates on your home, gravity will begin to pull it down the slope of your roof. There are many reasons this can be harmful to your home or even dangerous. In worst structural cases, this can lead to damage to costly gutter systems, structural damage to lower roof levels, and even destruction of mature landscaping around the perimeter of a home.

Low-slope roofs with parapet walls naturally keep snow and ice on the roof. On a sloped roof, however, large chunks of snow and ice can slide off as the snow melts. Avalanching snow is probable on roofing systems with a steep enough slope and/or a low coefficient of friction. This is especially dangerous for pedestrians walking below.

SOME REASONS WHY YOU SHOULD SPECIFY SNOW RETENTION SYSTEMS:

  1.  Damage/Injury – People and property can be struck by snow and ice falling from the roof. Property damage and injuries, even deaths can occur when snow is not properly retained on a roof.
  2.  Limited Access – Entrances to buildings can be blocked by snow and ice that falls from a roof.
  3. Roof Damage – When snow and ice masses slide off a roof, costly damage occurs.

CHOOSING THE RIGHT SNOW RETENTION SYSTEM

There are many types of roofing materials, each has advantages and disadvantages and each should be considered when determining the placement of snow retention on the building.

When considering whether to install a snow retention system on your roof, you may first want to consider what type of roof you have. Will your roof allow snow to slide? Probably. In places with heavy snows, like areas in Utah, it is common for snow to slide off of all types of roof systems, leading to heavy ice and snow build up in gutters, which causes damage over time. If you have a metal, tile, slate or membrane roof with a pitch of 1/12 or greater, snow will definitely slide off and cause problems.

Going For GOLD: In Snow Retention!

 

TRA’s – Terry Anderson (President) & Laurie Anderson (CEO) Trip to Whistler Canada 2017

Just as the world-class athletes prepare for an incoming storm of opponent competition, so should we prepare for all possibilities to keep incoming snow and ice from roof avalanching.

Keeping snow and ice from avalanching off a roof requires a system of superior strength. When strength really does matter to save lives and prevent damage to property, how does a home or business owner know what snow retention product is strong enough?

How does someone decide what product measures up?

How does one decide the best method of installing a safe and reliable roof snow retention system?

If your answer to these questions is, “I can find that out. I’ll just look it up online under building codes or ask my roofing contractor.” 

Well, good luck.

There are NO codes for roof snow retention! None. Nil. Nada. (Our owner, Terry Anderson, is serving on a committee right now to finally establish standards. Watch for updates on this in the future!) If a contractor starts sitting codes or standards, be wary. The contractor might have his own standards, and we sure hope they all do, but there are no national or international standards for snow retention.

This makes it very important for owners, architects, engineers, and contractors to take extra care when designing a snow retention system. At TRA Snow & Sun, we seek to offer high-quality snow retention devices ENGINEERED for the unique snow & ice and building conditions relative to each specific project.

Snow retention as a science has emerged as a technological know-how for human safety. The laws of physics have to be used when holding back lots of destructive snow and ice. Annual assets and personal damage from destructive sliding snow and ice are in the millions, however, the price of a human life is incalculable. If someone dies as a result of no snow retention or faulty snow retention, the liability threat to household owners and business proprietors is astronomical.

By retaining snow on the roof of a building and allowing even snow melt-off, injuries to residents/guests and property below the roof of a building can be avoided, saving money and limiting the possibility of personal loss. By installing snow retention you can:

  • Prevent danger to residents and guests.
  • Prevent costly roof and property damage.
  • Maintain safe access, keeping entrances/walkways free of snow and ice.
  • Promote energy efficiency by retaining snow which is a good insulation blanket.
  • Trust in the best with the highest quality snow retention devices.

How does one avoid the potential pitfalls of a bad snow retention product?

It can get perplexing with several hundreds of different snow guard types and designs to consider from. With a TRA snow retention system, you know you’re safe because we have gone through extensive product testing. Our products are built to last to the fail point of the snow retention system, not just the product. Unlike other plastic type snow guards that turn yellow and fail over time, TRA’s snow retention systems are superior in strength. Our superior snow retention is designed to manage snow migration on any type of roofing is made of stainless steel or brass.

Avoid Liability With Snow Retention

Ice_dam_slate_roof

There are several factors that one must evaluate when determining if a particular building requires a snow retention system.

The first question you should pose is “What would happen if snow slides off the roof?”

The second question is “Do we care?”

When snow slides off of a roofing surface, it can come crashing down or slide off and then piles up on whatever is below the edge of the roof. Snow retention is frequently used to protect landscaping around the perimeter of the building, to protect guttering systems around the edge of the roof, and to keep snow from piling either on a lower roof level or decks, sidewalks and at garage entrances. If nothing below the roof can be damaged by this avalanche of snow and ice, it may be best to let the snow and ice slide off unhindered.

However, what if what is below the roof could be damaged?

WHY SNOW RETENTION IS NEEDED

During the winter months, as snow accumulates on your home, gravity will begin to pull it down the slope of your roof. There are many reasons this can be harmful to your home or even dangerous. In worst structural cases, this can lead to damage to costly gutter systems, structural damage to lower roof levels, and even destruction of mature landscaping around the perimeter of a home.

Low-slope roofs with parapet walls naturally keep snow and ice on the roof. On a sloped roof, however, large chunks of snow and ice can slide off as the snow melts.

TRA Snow and Sun, Inc. offers AIA continuing education course, “Roofing Solutions for Alpine Regions”

 

roofing solutions in alpine regions, continuing educationIn response to requests from architects and other construction specifiers, TRA Snow and Sun has decided to continue with the popular continuing education course, “Roofing Solutions for Alpine Regions”.  

Learning how to protect people and property from dangerous falling snow and ice just got much easier with the online course created by TRA Snow and Sun and approved by the American Institute of Architects (AIA). When an architect designs a building there are hundreds of decisions to make besides the obvious, visual components that make up an attractive and functional building: what type of window to specify, what color carpet, or what type of roof are obvious ones. There are some specifications that are vital to the safety of those who will use the building and create liability for the architect and contractors.

If the building is located in a snowy, cold climate, special consideration should be given to the proper design and engineering of devices to retain snow and ice on the roof. Most construction professionals don’t realize the importance of snow retention devices and how critical they are in alpine regions.

Terry Anderson, nationally respected roofing consultant and owner of TRA Snow and Sun and Anderson Associates Consulting, has established himself and his companies as experts in the roof snow retention industry over 35 years and is co-author of the Concrete and Clay Tile Design Criteria for Cold and Snow Regions. The AIA online course, Roofing Solutions for Alpine Regions provides one credit hour of continuing education credit for architects wishing to maintain their license. It is also available for anyone wishing to understand the best way to design a roof in a cold or snowy climate. It incorporates Anderson’s extensive experience and deals specifically with:

  • The common roofing challenges that are unique to cold climates.
  • The advantages and disadvantages of the most common solutions to snow and ice on roofs.
  • The accepted roof design practices in Europe as compared to those in the United States and Canada.
  • The concepts and effectiveness of roof ventilation and snow retention in reducing snow and ice problems.
  • Several factors to be considered in the proper engineering of roof snow retention devices.

The course is available online (Ron Blank) or online (AEC Daily) 24 hours a day, 7 days a week. Credits are automatically submitted to AIA, CSI and other organizations by AEC Daily, one of the largest providers of free continuing education for architects, engineers, contractors, specifiers, and other construction professionals.

The Importance of Snow Retention

metal roof with snow guards in snow storm

Winter is on its way and snow accumulation is imminent across the U.S. The traditional approach to snow accumulation on homes and businesses is to remove it or allow it to slide off as it softens and melts. Unfortunately, this approach can lead to injuries or property damage and is not optimal for home energy efficiency in the winter. Snow retention on the roof can solve both of these problems by acting as an insulating force to retain heat indoors, as well as enabling snow to evenly melt off the roof without abruptly sliding off in a massive block. Here are some ways in which snow retention can benefit your home this winter.

  • Snow retention devices are mounted on the roof to prevent snow from dislodging in large masses and causing damage or injury to people or property below. They also prevent roof damage that will occur from prolonged ice dams.
  • Snow retention devices can be installed on any sloped roof in any area that receives snow. Snow fences and snow brackets are all versions of these snow retention devices, and are highly practical and cost effective solutions for heavy snow and ice. Here are some images of our new Snow Bracket I – Apex (valley & crest) for corrugated metal roofs.

  • Installing snow retention devices in strategic areas can help guard against injury and property damage over walkways, entryways, parking lots, congregation spaces, roof protrusions, and valuable landscaping.
  • Heat loss through the roof is a primary contributor to energy inefficiency during the winter. Maintaining a layer of snow on the roof can help to retain heat during the cold weather.

Installing Snow Brackets

Generally, snow brackets should be professionally installed by a licensed roofing or general contractor. This will ensure that the brackets are installed correctly, in the right locations, and that the proper quantity is used. There are a few factors that are considered when installing snow brackets. These include: average amount of snow at the location, snow load, pitch of the roof, type of roof and sheathing thickness, strength of the snow bracket, and type of fasteners. Considering these things will determine the number of brackets required for the roof. Snow brackets are not that difficult to install, but a roofing contractor will have the experience and safety devices to securely work on the roof and complete the installation efficiently.

Use The Prefect Retrofit Snow Guard Bracket H – Classic or Apex For Snow Retention

One of my older relatives used to say, when confronted with a dilemma, “What to do, what to do….”  It made me chuckle!

But, this phrase describes a dilemma for people confronted with snow and ice avalanching off their already installed roof.  They want to keep the snow up there

snow clips, snow guards, snow bracket

rather than down there

but what is the best solution?

First of all, retrofit is similar as well as different from new construction.  Basic questions need to be answered for new and retrofit construction.

  • What is the slope?
  • What is the snowload in the area?
  • What type of roofing product is being used?
  • What type of sheathing is under the roofing material?

For retrofit, snow retention installers don’t have the luxury of applying the snow retention devices as the roofing material is installed in a new project.  This is when “What to do, what to do…” might be heard under their breath!

How do you keep snow and ice from falling off while also maintaining a water-tight system when the roofing is already on the roof?  How hard is it to do this?

Contractors need a simple and effective solution.

For asphalt shingles, simulated shake, and other similar roofs, using TRA’s Snow Bracket H – Classic or Apex, there is no need to pull back the headlap to install a device. Butyl or caulking can be applied on the surface of the roofing product, then the bracket is installed directly into the sheathing using screws.  A clip is then placed over the screws.

Snow Bracket H – Apex

Snow-Bracket-H-Short

Snow Bracket H – Classic

Easy. Effective.

The reason this system will work on retrofit is because TRA’s engineering is done using the specific factors as mentioned above.  When installed using the engineered layout, the roof will now hold back the snow and ice that would have fallen off, damaging people or property below.

At TRA Snow and Sun, we help you find an Engineered Solution.  Call us for a free layout, provided within 2 working days.
