Is Plastic Snow Guard Retention Better Than Metal?

Every once in a while a customer will ask us why they should purchase our metal snow retention rather than the plastic ones they see. We typically don’t like plastic snow guards for many reasons.

The first reason is because of the type of adhesive used to attach plastic snow guards. Through our testing, we have found that failure exists when freeze-thaw temperature is introduced to the adhesive.
The second reason, they crack and deteriorate when continuously exposed to the sun’s ultraviolet light (UV). See the images below.
 
The third reason, manufacturers don’t warranty failure when the plastic snow guards pull apart from the adhesive.
From all of these reasons this why metal snow retention is a much wiser choice!

TRA Metal Clamp-on vs Plastic Guards

 

Most plastics eventually become brittle when exposed to the sun.

Because of its tough nature, metal can withstand the sun’s destructive UV rays. Over time plastic will crack and deteriorate when continuously exposed to the sun.

Cracked, Brittle and Broken “Plastic Snow Guards”

 

TRA’s metal snow retention systems are attached securely using a variety of durable and strong mechanical methods.

Unlike metal, plastic snow guards are usually attached to a roof using caulking, which is likely to fail for the following reasons:

  • If the roof is dirty or wet when installing this makes the adhesive not adhere properly. When have you ever seen a truly clean roof?
  • More common than not snow guards are installed at temperatures below 40 degrees.
  • Caulking cure time can be more than 30 days above 40 degrees.
  •  Over time plastic will crack & deteriorate when continuously exposed to the sun UV.

Unlike plastic, metal lasts.

Plastic snow retention manufacturers generally do not warranty the attachment just plastic snow guard. If a plastic snow guard fails, the architect or contractor becomes liable for the damage to property /or human life.

Next time you are near a roof with plastic snow guards, see if any are missing and let us know!

We recommend only metal snow retention because we know it can properly protect those in and around your home. For extra protection, we engineer from the sheathing up with the fastener and provide a warranty on the entire snow retention system. Before installation, we engineer a specific layout to see that the system is exactly what you need for your specific location and weather. Contact us with any of your project details and we’ll provide you with the best snow defense system that’ll get you ready for winter.

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.

TRA Snow and Sun, Inc. Offers Roof Snow Retention Specification Details Online

CAD Details LogoIn response to requests from architects and other construction specifiers, TRA Snow and Sun has added CAD details of many of their roof snow retention devices for easy access online.

TRA Snow and Sun, Inc., of American Fork, Utah, has recently provided their newly updated CAD details for their roof snow retention devices on their website – trasnowandsun.com.

Architects and specifiers are gradually moving away from keeping large volumes of information in their offices and many also work on their projects during non-business hours.  They have indicated some preferences as to how manufacturers can assist them to make their jobs easier.  One way is for manufacturers to provide online versions of their product data sheets, specifications and computer aided drawings.

TRA Snow and Sun President, Terry Anderson, patent holder on snow retention devices and other Snow and Sun products, expressed his desire to accommodate architects’ wishes.  “Obviously our world has changed.  In the old days I would drop off a binder full of product brochures, specifications, and drawings at an architect’s office, he would put it on his shelf, and then convert those later to use on his projects.  I would make in-person calls to update that information.  With the advent of our Information Age, most architects prefer a simpler and more timely and accurate method of obtaining their information.”

TRA Snow and Sun on CAD DetailsAvailable now by choosing the “CAD Details” button on the main navigation bar at trasnowandsun.com, are details for Snow Brackets™ A-L, details for all concrete tile manufacturers, asphalt, slate, metal and ceramic tile manufacturers, and decorative snow maple leaves, moose, bear and others).   There are also details for Gutter Brackets, Clamp-on Snow Fences, Deck Mount Snow Fences and their patented Ridge Riser.

Although the company still offers hard copies of all their information, they anticipate requests for information provided the old-fashioned way will continue to dwindle.  Taea Hall, Marketing Director, is spear-heading the effort to put all of TRA’s product details and drawings online, including their ventilation devices and solar mounting products.  ”CAD Details helps TRA Snow and Sun stay more connected to architects and specifiers.  Posting CAD Details on our website makes it easy to keep the information up to date and pertinent. Architects and specifiers don’t have to worry anymore if our information
is out of date.”

TRA Snow and Sun Announces New Cost-Saving Deck Mount Snow Fences

TRA Snow and Sun, Inc., is now offering new Deck Mount Snow Fence designs that will save the end user money.

TRA Snow and Sun, Inc., well known for their Snow Bracket snow guards and engineered snow retention system, has developed new lower cost deck mount snow fence called the Mount Shasta and Diamond Mount.

Terry Anderson, President, explains why the company, which also offers individual snow guards and other snow fences, decided to expand their product line.  “Our other snow fences have been very successful but we wanted to provide a less expensive option.  The Mount Shasta Deck Mount fits this need while still providing superior protection from sliding snow and ice.”

snow fence, snow retention, heavy duty snow fences, snow rails

The new deck mount system is designed for installation on most stick framed roof types and works with 3/4” X 3/4” square fence pipe (Diamond Mount style) or 1” (1.315”OD) fence pipe (Mount Shasta style).  Customers can choose from one or two rail designs.

The engineers at TRA Snow and Sun always take the snow load, slope of the roof and roof type into account when calculating how many snow fences are needed and how far apart they are placed on the roof.   The heavier gauge, larger snow fence mounts as well as this new mount are considered for each job.

All three factors determine which snow fence system is recommended.  If, for instance, a roof calculates out to require 1.2 fences from eave to ridge using TRA’s original deck mount snow fences, then two fences are specified because you cannot disregard the need for the .2 of a fence that would hold back snow.  If the new Mount Shasta deck mount snow fence calculates out to 1.8 fences from eave to ridge, that would also mean two snow fences, but the new snow fence clamp is less costly, still ensuring a safe system with less expense to the customer.

The Mount Shasta and Diamond Mount Deck Mount Snow Fences are available in steel, copper and Cor-Ten®, with finishes in raw steel, electro-galvanized steel, hot-dipped galvanized steel, mill finish copper, mill finish Cor-Ten®.  Powder coating is available. These snow fences are used on: asphalt shingle, cedar shingles, flat seam metal, granule metal, metal panel, slate simulated slate, tile roofs and woods shakes.

TRA Snow and Sun, Inc., located in American Fork, Utah, offers Roof Snow Retention Devices, Solar Mounting Systems and Roof Flashing Solutions. They supply to all types of customers, from the individual homeowner to the big developer and offer free engineered designs of all their systems.
