Snow Retention System: (Syn: Snow-Guard System) A series of unitized snow-guard devices or continuous assemblies installed for the purpose of retaining snow on a roof and allow the snow to evacuate slowly via thaw and sublimation rather than suddenly and unexpectedly via rooftop avalanche.
The Metal Construction Association is an organization of manufacturers and suppliers whose metal products are used in structures throughout the world. Since it was formed in 1983, MCA has focused on one key strategy – to promote the use of metal in the building envelope through marketing, education, and action on public policies that affect metal’s use.
MCA’s marketing and technical activities create awareness of metal, its applications, and its benefits. MCA also works to eliminate barriers to metal’s use in construction by supporting product performance testing, initiating research, and monitoring and responding to codes and regulations that affect metal.
These well-established activities help educate building owners, designers, installers, educators and those who determine relevant codes and standards. The result – more metal products are chosen for a broader scope of projects.
With metal roofs becoming more popular due to their longevity and environmental friendly nature, metal roofs are recyclable unlike asphalt roofs, the risk of sliding snow has increased. For the most part, when people have metal roofs installed they are not informed of the risk of sliding snow until damage to the roof or property occurs or the installers do not have the proper knowledge to provide a properly designed and engineered snow retention system.
Sky Products continuously receives calls from home and business owners stating they did not know that sliding snow could damage or shear their gutters from the eaves. Sky Product’s main business is to provide properly designed and engineered snow retention systems while educating clients on the subject of sliding snow from metal roofs.
Sky Products has based its design criteria on a couple of factors
Sky Products has designed and engineered snow retention systems for Federal, Provincial, Municipal and private construction projects across Canada since 2010. With the ability to provided stamped engineered drawings backed by factual load test results, Sky Products has been sought out by some of the largest metal roof companies and their installers to assist with their snow retention requirements.

Sky Products se spécialise dans les arrêts de neige et est le plus grand distributeur de stock S-5!® au Canada. Nous fournissons des produits S-5!® au Canada depuis 2010 et nous avons conçu, fabriqué et fourni plus de 200 000 pieds d’arrêts de neige S-5!® pour des projets de construction fédéraux, provinciaux, municipaux et privés au fil des années.
La famille de serre-joints S-5!® se fixe au joint du panneau de la toiture en métal en insérant et en sérrant une vis sans tête pour les mini serre-joints ou deux vis sans tête pour les serre-joints de taille standard. Ces vis sans tête feront légèrement onduler le matériau du joint, mais elles ne perceront ni ne pénètreront dans la membrane du toit. Cela fournit une fixation mécanique sonore qui ne se détériorera pas avec le temps.
Le serre-joint breveté offre une durabilité et une fiabilité inégalées par les adhesifs qui se dégradent avec le temps en raison des cycles de chaleur, des rayons UV et de l’ozone. Le serre-joint a été testé de maniere independante sur une variete de types de joints, de profils et de materiaux afin de déterminer les charges ulitmes faisant rompre la traction, qu’elles soient paralleles ou perpendiculaires au joint du panneau. Les serre-joints S-5!® sont conçus pour être robustes, tout en maintenant la toiture en place et la garantie du fabricant du toit !

When you order and receive your S-5!® non-penetrating standing seam clamps, you will notice that they come with round tip set screws as opposed to cup point set screws like some of S-5!® competitors. The following article was written by Rob Haddock of S-5!® in order to clarify the difference between using a round tip set screw versus a cup point set screw on a standing seam metal roof.

For over 20 years S-5! has been providing the metal roof industry with The Right solution to attach almost anything to metal roofs. When it comes to attaching snow guards, solar or other ancillary components to a standing seam roof, S-5! is the only way to ensure that NO HARM is done to the protective finish or the seam itself. In the end, it all comes down to a setscrew that ensures maximum holding strength while respecting the integrity of the roof.

ColorGard is mechanically attached with patented S-5!® clamps. S-5!® is the trusted name in metal rooftop attachment technology worldwide. S-5! patented, round-point setscrews grip the seam securely without penetration and without damage to the panel’s protective finishes. The clamps are precision-machined from aircraft quality, high tensile aluminum—not cast or plastic. All related hardware is non-ferrous stainless steel for lasting performance.

]]>A snow guard system, also called snow retention or ice rake, is intended to mitigate the risk of sudden and unexpected release of snow from the roof which can cause avalanche like situations below.
Why do I need Snow Guard System?
There are many reasons to use a Snow Guard System, but the primary one is to enhance the overall safety of your building project.
Further reasons are
Clamp on or adhesive type of snow guard?
There are a variety of reasons why adhering snow guards onto your roof may be an ineffective method in the design of a long-lasting and safe snow guard system.
Reason 1:
Adhesives tend to break down over time. So, adhered snow guards may work out for the 1st few years but over time, they may come off when a load is applied (like snow piling up behind them).
Reason 2:
Adhesives requires certain conditions in order to cure and these ideal conditions may only exist within a small window of time in many areas where snow retention is desired. The following is an actual installation procedure from an adhesive snow guard manufacturer;
For a successful installation the adhesive requires 28 days or (672 Hours) at 50 Degrees (F) or above to achieve full cure. Temperatures below 40 Degrees (F) will delay cure time, until temperatures reach 50 Degrees (F) or above to completely cure. Spring, Summer or early Fall is the best time to install adhesive mounted snow guards
Unless you can control the weather there really is NO perfect time to install an adhesive snow guard. A mechanically fastened or clamp to seam snow guard system can be installed ANY time of year.
Reason 3:
Adhered snow guards have much lower load ratings than mechanically fastened or clamp to seam style snow guards. Therefore, many more are required to stabilize the snow load.
Can S-5! Snow Guards be retrofitted to an existing roof?
Yes, S-5! Snow Guards are not only the industry standard but are the easiest to install resulting in reduced labour costs! Further, installed properly, S-5! Snow Guards can last the lifetime of the roof!
Should the Snow Guard System be customized to the Job?
Yes, every job is different. It is important to take into account dormers, upper and lower roofs, multiple roofs on a building and if any part(s) of the roof(s) create valleys where snow funnelling can increase snow loads further down the roof.
