Engineered Snow Retention for the Bill and Helen Norrie Library
S-5! DualGard™ provides a penetration-free snow retention solution for a standing seam metal roof in snowy Winnipeg.
The Challenge
For more than one-third of the year, Winnipeg experiences heavy snowfall. The architect was concerned about snow build up and potential rooftop avalanches on the library’s new slick Agway AR 38 double-fold standing seam metal roof, especially the south side of the building where there is a large public access area.
The outdoor seating area is located directly under the eaves of the roof. When the spring thaw occurs, it is important to protect the library patrons from snow sliding off the roof. Therefore, the library needed a snow retention system that would provide safety.
Project Stats
Winnipeg is the capital and largest city of the province of Manitoba in Canada. It is centered on the confluence of the Red and Assiniboine rivers.
Construction of the city’s new $9.3 million, 14,000-square-foot Bill and Helen Norrie Library began in the fall of 2019 and replaced the original library which first opened in 1961.
The new state-of-the-art facility includes a multi-use public space, an outdoor reading deck and activities area, and a children’s area with three reading nook playhouses.

The Solution
Roofing Contractor, Claude Simard Metal Systems, contacted long-time S-5! distributor, SkyProducts for an engineered snow retention system that could be custom powder-coated to match the roof. They chose S-5!’s DualGard snow retention system. DualGard is a complete, two-pipe aluminum, snow guard system with strength, testing and quality for almost any standing seam profile, in addition to corrugated and many trapezoidal, exposed-fastened roof profiles.
Sky Products worked with Protech-Oxyplast in Montréal, Québec to provide the perfect color matching powdercoated finish and texture―GR Grey Sandtex 1-PE-182 “c” Matte Polyester―to match the new grey metal roof.

“Snow guards can be pretty tricky and pretty risky. We wanted to use a product from a manufacturer who we knew would guarantee their products for the long-term. Not only does S-5! provide quality products, great customer service and remarkable technical support, the company has been around since 1992 and stands behind its products with a warranty like no other. As an added bonus, our engineer was able to custom-engineer the product for this project with S-5!’s web-based snow calculator.”
