By retaining snow on the roof of a building and allowing even snow melt-off with snow guards and snow rail systems, injuries to residents/guests and property below the roof of a building can be avoided, saving money and limiting the possibility of personal loss.
Snow Retention Systems are widely implemented in Europe as a means of preventing roof damage due to the sliding of snow and ice masses that accumulate on roofs during winter months in alpine regions. As snow accumulates and is retained on a roof, it serves as an insulating blanket to promote energy efficiency. Furthermore, 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.
Roof Snow Retention is a system of devices, commonly called snow guards, snow clips, snow rails or snow fences that are mounted on your rooftop which prevent snow from avalanching off in large masses damaging people and property below. With a roof snow retention system, snow and ice drop off in small, harmless quantities or melt completely before falling to the ground. Originally used with slate roofs, our snow retention devices are a practical, cost-effective addition to any sloped roof in areas that receive snow. Snow rails, snow fences, and snow brackets can be installed on all roof types to protect against snow and ice damage.
It is especially important to install them above:
Testing: Each one of our products has been tested from the sheathing up. We know at what point each component fails from the bracket down through the fastener into the roofing material and sheathing and engineer our layout based upon those factors.
Engineering: At TRA Snow and Sun, we design each snow guard and snow rail system specific to your roof and provide you with a free snow retention plan, layout, and product detail.
TRA Snow and Sun’s product line saves property owners money and limits the possibility of personal loss because 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.
We have a variety of materials and finishes for our snow guards and snow rail systems.
*We can provide Paintlock brackets unpainted BUT they must be painted before installing or rusting will occur.
During the 1970-80’s most states adopted building codes that required structures to support the weight of the building materials (dead load) and the weight of the snow, ice, water, people, etc. (live load). By the year 2000, international building codes were universally adopted with similar standards. So, if the structure was built post 1975, you most likely will not have any weight problems. In some cases, structural engineers can take deductions assuming snow shedding off a structure, particularly with large sloped metal roofs. Large sports arenas, hospitals, schools and other structures with high occupancy and liability should be reviewed by a licensed structural engineer.

Snow Brackets™ are typically packaged 100 per box. However, you can order smaller quantities.
At TRA Snow and Sun we do not have a certified installer program. Our products are relatively simple to install. Any licensed Roofing/General Contractor is capable of installing our products. It is critical however that the correct number of snow brackets, and the correct positioning of snow fences be installed. We offer free engineering and design to ensure that contractors understand our requirements; these drawings and details make installing relatively simple. The average homeowner can understand our snow retention plans, and we encourage homeowners, architects, general contractors, etc. to look at the plan and ensure that the Roofing Contractor is installing the devices correctly. We will provide a copy of our snow retention layout to anyone involved in the project that would like one. One thing to note, in cases of retro-fit it is wise to contact your original roofing contractor in cases where warrantees are still in place, some roofing contractors do not allow other contractors to work on the roof while a warranty is existing.
Great Question! Since what you are trying to prevent is damage and injury caused by sliding snow and ice, installing the correct number of Snow Brackets™ is extremely important. Installing too few will result in snow and ice avalanches – exactly what you’re trying to prevent. Installing too many snow guard brackets is a cost that you don’t need.The two main factors determining the correct number of Snow Brackets™ are the amount of snow at the project location (ground snow load), and the slope or pitch of the roof. Other factors that play a large role are the type of roof, the roof sheathing type and thickness, the strength of the Snow Bracket™, the type of fasteners used, the snow drifting conditions, ice damming, etc. With all of the variables, you can see why determining the number of Snow Brackets™ is complicated.
At TRA Snow and Sun, we have worked hard testing our snow guards and snow rails systems in various conditions to determine correct strengths under numerous installed conditions. Using the data specific to your roof, our engineering will determine the appropriate number of Snow Brackets™ needed for your roof.
Our sales staff can provide you with exactly how many Snow Brackets™ you need using this information. Just email us your info or give us a call
Submit our Snow Retention Checklist. TRA Snow and Sun offers design and engineering as a free service because our main goal is to provide high quality systems that will work correctly for many, many years.
The short answer is no. There may be some codes that exist on a local level. But there are no national or state codes for snow retention through snow guards or snow rails systems. This makes it very important for owners, architects, engineers, and contractors, to take extra care when designing a snow retention system. At TRA Snow and Sun, we seek to offer high quality snow retention devices engineered for the unique snow & ice and building conditions relative to each specific project.
TRA Snow and Sun recommends, for a number of reasons, that a licensed roofing contractor install snow retention devices such as snow guards and snow rail systems. Working on the roof is hazardous, and roofing contractors should be equipped with the proper safety devices to adequately work on the roof. Installing snow retention devices without permission from the original roofing contractor may void warranties that may be existing. Licensed roofing contractors have experience keeping a roof watertight, and are most suited to install snow guards and snow rail systems. We understand that even with these warnings, some homeowners would like to install their own snow retention devices. Installing snow guards in most cases is not difficult; homeowners are usually capable of performing the installation. It is critical, however, that snow retention devices are placed in locations approved by TRA Snow and Sun for snow guards and snow rail systems. Please call or email and ask for a FREE design for your snow retention project. We are willing to work with homeowners who wish to perform their own snow guard installation.
All snow retention devices should be checked as part of a yearly roof inspection by an experienced roofer or snow guard installer. Any defects in materials and workmanship in the snow guard or snow rail systems should be reported to the manufacturer immediately.
The maintenance on the Standing Seam Snow Fence is as follows:
Once a year, provide a visual inspection, making sure all end caps, ice flags, collars, etc., are in proper repair. Make sure nothing is loose, has moved, or is missing. Replace any damaged or missing product. Report any damages to TRA for replacement covered parts.
Once every two years, check the torque of the Snow Fence carriage bolts and locking nuts, making sure they are still at 30-foot pounds of torque.
TRA Snow & Sun, Inc. is not responsible for any snow guard system that has not been properly maintained. TRA Snow and Sun, Inc. reserves the right to test brackets and inspect the roof before bracket replacement.
It is incumbent upon the owner of the snow retention system to perform said maintenance to remain eligible for TRA Snow & Sun’s PRODUCT WARRANTY. TRA SNOW & SUN WILL NOT BE HELD LIABLE FOR PROJECTS WHERE PROPER MAINTENANCE HAS NOT BEEN PERFORMED.
