ASTM’s current standard that is being developed is titled “Standard Test Method for Snow Retention Devices attached to Wood Sheathing”. TRA, a current member of the ASTM task group, is helping the development move along by testing its products per the standard and then providing the task group with the results for analysis. Several hundred test results will be provided over the next several months.
In addition to providing valuable information to the task group, TRA is also benefiting from the process. We are seeing great results and increased values on our Apex snow bracket design, that is being used for the tests. What does that mean? If test results continue, the Apex profile bracket will prove to be a better value for the customer with fewer snow guards required.
Due to Covid-19 concerns, the goal remains the same to have a completed standard ready to submit to the main committee by April 2021.

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:
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.
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.
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)
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.
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:
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.

Terry Anderson, owner of TRA Snow and Sun, chairing a meeting in Washington, DC and webinar of the ASTM Committee for roof snow retention standards. Did you know there are currently NO roof snow retention standards to prevent needless deaths from snow and ice falling off a roof like what happened to a mom and her nine year old son on a skiing vacation at Kirkwood Resort in California last March? That MUST change! He is working hard to fix this issue.
TRA Snow and Sun knows that it is important to specify snow guard roof snow retention. Snow retention should be as worry free and easy as possible for architects, designers and homeowners. So over the last several months we worked hard with our partners to improve the quality and ease of creating a good, safe, and specific roof snow retention specification.
We are proud to announce that our Division 07 7253 Roof Snow Retention specifications have just been enhanced and updated!
Designers and contractors can read and download the snow guard specifications using MasterSpec or with SpecLink. They can also contact TRA Snow and Sun via phone or through our contact page at anytime and we will e-mail the latest snow guard specifications which can be merged into master specification documents.
With our updated snow guard specifications, designers have the necessary knowledge base to create the perfect snow retention system for their unique project design. We have made it as easy as ever!
TRA Snow & Sun’s snow guard products provide superior benefits to building designers and contractors because they get a safe SYSTEM, not just a good product. We test and engineer our products based on the components of their specific roof system (snow guard, sheathing, attachment, slope, snow-load, etc.). This dramatically decreases the designer or contractor’s liability!

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 is 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:

Snow Retention Case Study – Providing Engineered Snow Retention Solutions for HALF THE COST!
TRA Snow and Sun solves problems! It’s not just our motto to provide Engineered Solutions. We really DO IT!
On an addition to a home in Northwest Montana with a high snow load (100 psf); how do you retain snow on a cedar shake roof with a 12/12 pitch, whilst keeping it economical, aesthetically pleasing, and in line with the existing design?
After reviewing their options, Vandelay Construction was ready to order from a competitor, but was concerned about the high cost of the snow retention system, so they did one last internet search of roof snow retention. They found a project with TRA Snow and Sun snow retention in Bozeman, Montana, liked our product and designs, and contacted us.
Using the information the contractor provided to us, we increased the thickness of the copper from the standard ¼” to 3/8” and designed a 3 rail snow retention system (D3H Deck Mount Snow Fence) specific to the project – cedar shake, 12/12 slope, copper, attaching to 16” OC rafters. Copper was used to match the decorative end caps on the heavy timbers in the construction of the building.
Not only did the homeowners get a beautiful, warrantied system, but OUR SYSTEM WAS HALF THE COST OF OUR COMPETITORS.
We love the result. See for yourself.
At TRA, we provide Engineered Solutions to all kinds of problems. Let us help you with your snow retention needs!
The owner of TRA Snow and Sun, Terry Anderson, recently visited Laie, Hawaii and was thrilled to see construction on some buildings at the BYU-Hawaii Campus and his products being installed! – RIDGE RISERS!
Concrete tile is a good choice in the tough, humid climates like you find in islands of the Pacific. Whereas wood can rot and asphalt shingles wear out due to weather conditions, tile gets stronger over time and is not as susceptible to the ravages of the climate conditions.
As a roof consultant decades ago, Terry helped the Mormon Church with some roof consulting on tile roofs in the Hawaiian Islands. Concrete tile was used on many buildings then. The roofs have lasted for decades and this year on his trip, he discovered that Boral Tile is being re-installed on some of the buildings on campus.
TRA Snow and Sun’s Ridge Risers were not invented until recently (and patented by Anderson) so Terry was excited to see them being used on the re-roof project.
Ridge risers are used on: Concrete and Clay Tile Roofs
• They elevate the nailing board for proper ventilation
• Easy application for hip and ridge tiles
• They fit all tile profiles at the hips and ridges
• Long term durability
We have Ridge Risers in stock right now! Call 800-606-8980 or visit: https://trasnowandsun.com/
