A Guide to Snow Retention Systems: Snow Brakes and Snow & Ice Guards on Roofs - selection, mounting, maintenance, product sources
What is a snow retention device? What are "Snow Guards" - do they also hold ice?
|
Snow retention systems is a generic term used for a wide range of devices placed on roofs to prevent snow and ice from sliding down and falling off the roof - an event that is dangerous to people below and that can damage buildings and building components.
The types of snow retention systems can be described by the snow retainer physical shape or design (one manufacturer provides an abrasive roof coating), but keep in mind that there is also a variety of methods of attaching the snow retainer device itself to the roof surface. In this article we describe all of the different types of snow retention devices, their attachment methods, and their advantages and risks.

Snow Brakes or Snow Guards on Metal Roofs
Snow brakes, or snow guards are used on metal roofs covering buildings in snow-prone areas. Our photo (left) shows snow guards on a modern computing center building on the Bard College campus, Annandale, NY.
- Snow guards are installed as a safety measure to avoid clobbering someone entering or exiting the building at a bad moment. At a New York property we watched as a huge curl of snow and ice fell off of a metal roof onto a vehicle parked close to the building, smashing the car's hood.
- Snow guards are installed to avoid knocking gutters off of the structure. Properly placing gutters so that the outermost gutter edge is at or below the extended roof slope plane can help prevent ice or snow from knocking gutters off, though in heavy snow areas we often see that homeowners have given up on the idea of keeping gutters on a metal-roofed home, using other means to direct roof runoff away from the building.
- Snow guards are installed to avoid piles of snow on entrance steps and platforms
- Snow guards are installed to avoid damage to lower roofs. For example, heavy loads of snow and ice suddenly falling from an upper roof slope on to a lower standing seam metal roof may bend or damage the standing seams, and snow or ice falling from an upper to a lower slate or tile roof could break slates or tiles on the lower surface.
- Snow guards are also installed to avoid damage to shrubs or other landscaping or to protect mechanical systems such as air conditioning compressor/condenser equipment located beneath the building eaves
Our photo at left illustrates how snow creeps outwards from the roof edge in a shelf formation when no snow retention system is installed on a building. Eventually the snow extending out from this roof falls onto a lower roof at this building (see photo at page top), with a resounding whoomph that shakes the walls. Snow guards are needed here.
Snow guards and a bit of their history are discussed in NPS "From Asbestos to Zinc" from which we quote:
Snow guards or snow brakes, as they are sometimes called, began appearing on slate and metal roofs of New England in the late 1800s.
The tremendous quantities of snow and ice that accumulated on these roofs made the wood or metal diverter, typically attached above the front entry, an ineffective tool in preventing the snow from sliding down the roof.
With snow guards in place, the snow would eventually blow away or remain until it melted. Not only was the risk of damage to objects and persons below avoided, but the banking of snow and ice at the eaves was prevented, thus eliminating the chances of backwater and consequent leaks, as well as a straining of the gutter structure.
This photo of snow brakes on a standing seam metal roof demonstrates that snow guards or snow hooks were widely used on metal roofs for more than 100 years.
At SLATE ROOF HARDWARE we show more snow brakes and guards used on slate roofs. Also see SLATE ROOF INSPECTION & REPAIR and see our metal roofing home page, METAL ROOFING.

Photographs of Slate Roof Snow Guards & Snow Brakes or Snow Hooks
Below we include our own photographs of snow brakes, snow guards, snow hooks, and other on-roof devices to control against snow damage and hazards, including snow guard examples and similar roof snow brakes & materials from the 1800's up to 2012.
|

While in general snow retention systems use the terms "snow guard" and "snow brake" or even "snow bracket" and "snow hook" interchangeably, for clarity we call the long horizontal device shown on a slate roof at left a "snow brake" or "snow fence" or "snow bar" while we refer to individual, non-linear devices attached to the roof surface as snow guards.

Wire Loop snow "hooks" are snow retainers that are made using a heavy gauge wire instead of flat metal or plastic protrusions show in other photos in this article.
Snow Hooks, the wire loops shown in our photo at left were installed during the slate roof installation by nailing the wire loop's supporting base to the roof deck between the side butt joints of slates.
|
Here are new copper snow guards being installed on a slate roof that was also being replaced/repaired on the Wimpfheimer Nursery building on the Vassar College Campus, Poughkeepsie, NY - March 2010. |
- Traditional structurally-secured slate roof snow guards include a nailed bracket that is covered by upper or succeeding courses of slates (photo at left), and are installed during roof installation.
To retrofit snow guards to a slate roof it may be necessary to remove and reinstall some slates to avoid drilling through slates or trying to glue a snow guard to an older, weathered surface.
|
Metal Roof Snow Retention Systems
- Metal roof snow guards are often installed by gluing the snow guard to the metal roof surface in the center of pans between the standing seams. [2]
Our photo (left) illustrates a plethora of snow guards fastened to a metal roof on the Vassar College Campus. It appears that the maintenance department has tried a variety of products on this roof, with mixed success.
Our second photo (below left) shows the same building roof in January 2013, with partial snow cover. You can see these snow guards at work as they prevent snow and ice on the upper roof slope from sliding down and falling off at the roof eaves.
|
How to Install Snow Guards on a Metal Roof
Because of the problem of poor adhesion of the snow guard to the roof that later come loose or creep down the metal roof, manufacturers offer tips for a successful installation including:
- Clean the metal roof surface in the area where the snow guard is to be glued. We use isopropyl alcohol which has not, in our experience, ever harmed the roof's finish surface. Some other solvents such as acetone are not recommended as they will dissolve paint or other coloration on the roof, while other recommended solvents such as xylene may work well but can be highly toxic and thus more dangerous to handle.
- Read the instructions from the manufacturer regarding how the snow guard adhesive should be applied - how much, at what temperatures, with how much runout at the edges of the snow guard. (Leaving no run-out may look better but it asks for snow and ice push that ultimately loosens the snow guard.
- Snow guard adhesive often needs up to four weeks to cure, longer if temperatures are below 50 degF. During the curing process the snow guards may creep down a hot roof. Use string or other support clamped across the roof to hold the snow guards in place until the adhesive is fully cured.
|
Here are metal snow guards clamped to the steams of a standing seam metal roof. These snow guards are not installed following the recommendations of some manufacturers who suggest their guards be glued to the pans centered between the standing seams.
We like this implementation: snow guards are clamped directly to the standing seam on the roof - no holes are made in the metal roof surface, and we avoid the problem of snow guard creep: glued snow-guards that creep down or fail to adhere to the roof surface. These snow guards look like and probably are the painted cast aluminum RT SNow Guards produced by Berger Building Products[1].
We spoke with the occupants of this building in Poughkeepsie, New York about their experience with this installation. The staff confirmed that in eight years of winter snow collecting on the roof, this snow retention system had functioned without fail - important because customers park their cars quite close to the eaves of this building. |

- Metal roofs using long horizontal snow bars or snow brakes (photo at left) have these snow retention systems installed using clamps on individual standing seams.
The metal roof shown at left sports both a metal roof snow fence and clear plastic individual snow guards installed four in each metal roof pan - clearly the maintenance crew were having trouble retaining the snow on this roof. Snow retention on this roof was extra important to protect a bevy of HVAC equipment located just under the roof eaves.
- Corrugated metal roofs also accept snow guards, typically made of bronze or galvanized iron and referred to as a Snow Guard Shoe.[1]
- Slate roofs (photo shown earlier in this article) using long horizontal snow brakes mount the brake or fence on brackets nailed to the roof, with the nailed portion of the mounting bracket extending up under succeeding courses of slates to avoid risk of leaks around mounting bolts.
|
Snow Retention Device Installation Specifications for Spacing
Snow Guard Spacing Distances
Experts point out that for the placement of individual snow guards (as opposed to long horizontal snow fences or snow brakes) depends on the pitch of the roof. According to Precision Snow-Guards[2]
- For roofs sloped 0 (flat) to 2 inches in 12 of rise (2/12 Slope), snow guards are placed in one staggered set across the lower roof edge staggered two feet on center. [Why you would need snow retention guards on a flat or 0-slope roof escapes us - Ed.]
- For roofs sloped more than 2/12 and up to 6/12, install two rows or sets of staggered guards, two feet on center
- For roofs sloped at 6/12 and steeper, install two rows or sets of snow guards in straight lines (not staggered) across the roof eaves
- For metal loop wire type snow hooks or snow guards (photo at left) you can see that to work at all, since these devices have much less surface area than a flat or bar type snow guard, they have to be installed in many staggered rows over half or more of the roof surface. The snow hooks shown here are installed on a slate roof at the Justin Morrill Smith historic home in Vermont. Metal loop snow guards for shingle,slate, and cedar shake roofs are typically made of copper wire. See Berger Building Products for a source.[1]
- Snow brakes, snow fences, snow rails, or similarly-called continuous bars or fences to retain snow on a building roof are usually installed as a single continuous system across the roof eaves, typically 1 to 3 feet above the eaves.
5 Snow Retention System or Snow Guard Installation Mounting Methods
Individual snow guard mounting methods vary depending on the roof covering material. All snow retention systems use one of these methods to provide snow and ice retention for building roofs.
Our photo (left) illustrates structurally-mounted snow brakes or rails on a tile roof covering the Oslo Folk Museum. As Norway experiences heavy snow fall, you will observe that the snow brakes are installed in two tiers and a close examination shows that the rail brackets are secured to the roof structure below.
- Structurally-connected snow retainer mounts: A snow retention device or its mounting bracket is fastened through the roof surface to the underlying roof sheathing or framing structure. For steel roofs the retainer mount may be welded to the roof surface.
For slate, tile, or shingle roofs, the leak risk of this approach can be minimal as the fasteners can be covered by subsequent courses of roofing material. For metal roofs we prefer not to puncture the metal roof surface. Structurally-connected snow & ice guard system mounts should be used where the loads (weight) of snow and ice are very great such as on large roofs or in deep-snow areas, or where the snow rail is itself large and heavy.
Watch out: depending on the total loads imposed by snow and ice on a roof, failures are still possible with structurally connected snow retainer systems if the screws, bolts, or their connection points are not adequately designed & installed on the roof.
- Clamp-on snow retainer mounts: for standing seam metal roofs, various patented clamps secure to the raised rib portion of the standing seam and in turn provide a base for mounting snow shoes, snow guards, or snow rails or fences.
The clamp mounting method for mounting snow guards & fences is also quite strong and has the advantage of avoiding penetrations of the roof surface. Of course clamps mount on standing seams of metal roofs, not other roof surface shapes. However the weight of snow and ice trying to slide down the roof - the load - is carried by the roof covering, and is transferred to the roof structure only by the metal roof mounting clamps beneath the roof surface.
Watch out: metal roof manufacturers warn that because snow guards mounted on the standing seam of a metal roof transfer load to the metal roof covering, good roof installation will be sure during roof installation to locate metal roof mounting clamps at a location and spacing to be sure that the metal roof is well-secured to the roof deck below areas where a snow retention system may be mounted. Otherwise loads on the roof can bend or damage the metal roofing.
- Adhesive-bonded snow retainer mounts: a snow guard or supporting mount for a more extensive snow retainer system is glued to the surface of a metal, glass, or plastic roof surface. [See photo at left showing glued-on snow guards on a glass roof at a bank drive-through structure in Rhinebeck, NY]
Watch out: Most snow retention system failures occur with glued-on snow guards that were not properly bonded to the roof surface.
Depending on the care of installation and other factors, some contractors report having difficulty keeping glued mounts in place, observing them sliding down the roof before the glue has cured or dislodging from the roof surface entirely later-on.[5] Note that most snow retention system product manufacturers warrant their system if it is installed according to their specifications.
- Clip-on snow retainers: Atas and others offer clips that mount to the horizontal rail of a snow or ice retaining fence or rail, providing an additional degree of snow and ice retention on roofs. On a metal roof one or at most two clips are mounted in the space between the standing seams. [5][6]
- Snow-retention coating: for metal roofs, SnowGrip[10] offers a patented abrasive-based snow-retention coating for metal roofing. The entire roof surface is coated with an abrasive material.
Is there a Snow Retention System Building Code?
Short answer: no.
A snow and ice retention system that mounts to a standing seam metal roof by connecting to the roof covering has to resist the forces of snow and ice pressure by transmitting those forces from the snow fence or snow guard to the roof surface and through that roof to the roof mounting clips. There are building codes for building roof system wind-uplift resistance on metal roofs but there are not building codes that describe the "shear strength" resistance for the fasteners used to secure metal roof panels to the roof deck.
Failures in the mounting system for snow retention devices can occur if the snow retention system is not adequately secured to the building structure itself. Damage to the roof or roof covering can also occur if the total snow and ice load bends or breaks the roof covering (such as a standing seam metal roof).
If the total load causes the roof mounting clips beneath the metal roof to shear. In our OPINION given the total number of clips used to secure the length of a standing seam metal roof panel to the roof deck below, the chances of shearing of all of these roof mounting clip screws, properly screwed to a sound plywood or even OSB roof deck should be minimal. However it is plausible that high snow and ice loading near the roof edge, imposed against snow guards or a snow fence in that location, could provide a bending force that pulls fasteners out of the roof deck, bending or damaging the roof, and sending snow guards and snow and ice to the ground below.
Adhesive failures are reported by Galow, Anderson, and others as a common snow retention system failure for glued-on snow guards on metal roofs, as we discussed above. [15][20]

- Roof Tiling & Slating, a Practical Guide, Kevin Taylor, Crowood Press (2008), ISBN 978-1847970237,
If you have never fixed a roof tile or slate before but have wondered how to go about repairing or replacing them, then this is the book for you. Many of the technical books about roof tiling and slating are rather vague and conveniently ignore some of the trickier problems and how they can be resolved. In Roof Tiling and Slating, the author rejects this cautious approach. Kevin Taylor uses both his extensive knowledge of the trade and his ability to explain the subject in easily understandable terms, to demonstrate how to carry out the work safely to a high standard, using tried and tested methods.
This clay roof tile guide considers the various types of tiles, slates, and roofing materials on the market as well as their uses, how to estimate the required quantities, and where to buy them. It also discusses how to check and assess a roof and how to identify and rectify problems; describes how to efficiently "set out" roofs from small, simple jobs to larger and more complicated projects, thus making the work quicker, simpler, and neater; examines the correct and the incorrect ways of installing background materials such as underlay, battens, and valley liners; explains how to install interlocking tiles, plain tiles, and artificial and natural slates; covers both modern and traditional methods and skills, including cutting materials by hand without the assistance of power tools; and provides invaluable guidance on repairs and maintenance issues, and highlights common mistakes and how they can be avoided.
The author, Kevin Taylor, works for the National Federation of Roofing Contractors as a technical manager presenting technical advice and providing education and training for young roofers.
