Roofing Materials For Snow Retention

As the weather warms up, it is important to remember that Spring can come with its fair share of complications. For example, when the snow that has been piling up on roofs starts to thaw, it can come down in an unexpected manner, with catastrophic consequences for whatever is caught beneath the cascade. This may mean damage to gutters, the landscape, vehicles and sometimes even passers-by.

At AMSI, we offer S-5!® snow retention products, which are the most effective on the market at preventing such disastrous outcomes. Here are three examples of how our S-5! snow retention products can help with snow retention needs:


Chemung-Gold5Like its name suggests, ColorGard promises to provide outstanding protection while retaining its beautiful color in spite of its constant exposure to the elements. The S-5! ColorGard is the only snow retention system designed and engineered on a site-specific basis for perfect color and finish matching. The ColorGard systems employ Kynar 500® and Hylar 5000® (PVDF) paint systems which are “coil-coated” and oven-cured. This is the only finish application methods that can be warranted against color fade for 30 years or longer.

SnoRail and SnoFence

S-5-SnoFence3The S-5! SnoRail and SnoFence systems are favorites of architects and roof designers looking for an attractive snow-retention solution. Both systems offer a high-tech look that doesn't clutter the lines of the roof. The systems are attached with patented S-5-ASF and S-5-BSF brass or aluminum clamps utilizing the patented round-point setscrews delivering a long term, dependable solution for traditional standing seam and sheet copper roofing. This specialized design for attaching the SnoRail and SnoFence allows thermal movement to remain unrestricted. The clamps are precision-machined from aircraft quality materials - not cast or plastic. All related hardware is non-ferrous, compatible stainless steel or brass for lasting performance.


XGard_2PNex-021314_1.00X-Gard comes as either a one-pipe or two-pipe system that provides outstanding strength. In fact, the tests show it to be the strongest and thus most reliable system of its kind on the market. It's a new kind of solution, that features a unique design and shape allowing the X-Gard™ system to provide reliable snow retention solution in a wide variety of situations. X-Gard™ is mechanically attached with patented round-point setscrews, gripping the seam securely without penetration and without damage to the panel’s protective finishes. The X-Gard can be easily retrofitted to existing roofs or incorporated into new construction design. It can be installed any time during the year on almost any metal roof profile.

The Secret Behind S-5! Snow Retention Products

The cleverly designed S-5! setscrews offer unprecedented holding strength.  The average ultimate failure load on the 2-screw clamp is in the range of 1,600-2,400 pounds – three times that of our competitor’s clamps. S-5! clamps attach to the panel seam by the tightening of two “bullet-nosed” stainless steel setscrews against the seam material. (This is usually done with an industrial grade screwgun.) The round point setscrews compress the seam material against the opposite wall of the clamp. They will “dimple” the seam material, but will not penetrate it. Threaded holes in the clamp (stainless hardware is provided) enable the easy attachment of various ancillary items to the clamps.
