Standing Seam Metal Roof Panels by Westform Metals

Founded in 1961 in Chilliwack, British Columbia, Westform Metals has evolved from its humble beginnings as a small, family-run lumber yard into a leading manufacturer of metal roofing and siding throughout Western Canada. With production facilities located in both Chilliwack, BC, and Lacombe County, Alberta, the company specializes in providing custom-cut cladding tailored to the needs of residential, commercial, and agricultural projects. Their Prolok 12" and Prolok 16" standing seam nailstrip panels are known for their sleek, modern appearance and are available in more than 80 colors. Committed to environmentally responsible practices, Westform Metals incorporates 30% recycled steel into its products and supports contractors with helpful tools, such as CAD design services and a visualizer tool. This dedication to quality and service has made Westform Metals a reliable choice for metal roofing solutions.

Prolok 12-inch and 16-inch

The Prolok 12-inch and 16-inch panels from Westform Metals are precision-crafted metal cladding solutions designed for both roof and wall applications. Offered in 12-inch and 16-inch widths, each with a pronounced 1-inch rib, these panels create bold shadow lines that enhance their modern, architectural style. The panels' sizes and available lengths are engineered for easy transportation and installation, appealing to both professional installers and DIY enthusiasts. Their concealed fastening system keeps all hardware hidden, resulting in a streamlined appearance and providing extra protection against water and wind infiltration. Constructed from high-quality steel in 26 or 24-gauge thickness, these panels are finished in a range of durable coatings and colors to accommodate different project needs and withstand varied climates. The robust rib and interlocking seam design add strength, providing resistance to wind uplift, heavy snow, and roof traffic, while also safeguarding against leaks. Suitable for installation on roof slopes as low as 2:12, Prolok panels require minimal maintenance and can be installed vertically for walls or on sloped roofs in both new builds and renovations. Their design also accommodates thermal movement, helping to maintain structural integrity throughout the seasons.

This roofing panel accommodates various snow retention systems, with a focus on compatibility with adhesive-mounted polycarbonate snow guards. Ensuring proper adhesive application is crucial to keep the snow guards firmly in place and prevent issues related to moisture or refreezing. Because the panel has a stamped surface rather than a smooth one, a heavier layer of adhesive is generally needed. There are multiple snow guard choices available to meet different requirements, including larger models like the IceJax II, Snojax II, and SnoBlox Ace, as well as smaller ones such as the SnoBlox Deuce and IceJax I. For enhanced protection against sliding snow and ice, we recommend the SnowBreaker and SnowBreaker 3M models. The panel's ribbed structure supports both adhesive-mounted and clamp-on snow retention systems. Clamp-on options include the SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar rail systems, which attach using stainless steel SnoBar clamps or aluminum RoofClamp devices. To ensure the best fit for a particular roof, we recommend testing a clamp sample before making a final selection. Ultimately, users are responsible for determining the suitability of these products for their specific panel.

Considerations for Adding Snow Guards to Standing Seam Roofs by Westform Metals

Order product samples to verify proper compatibility.

Request samples of snow retention products to ensure they fit your specific roof profile. This step helps prevent installation issues and guarantees reliable results. Samples are available in any quantity, with no minimum order requirements.

Install snow guards to distribute the snow load evenly.

Place snow guards to spread the weight of snow and ice evenly across the roof. Stagger pad-style guards and arrange bar or rail systems in straight, continuous rows. Avoid isolated placements to prevent structural stress; refer to the Spacing Guidelines for detailed recommendations.

Opt for non-penetrating installation methods.

Choose snow guards for standing seam metal roofs that attach with clamps or adhesives, rather than screws or nails, to preserve your roof's warranty and reduce the risk of leaks.

Incorporate ice control accessories when necessary.

If ice buildup is common, consider adding ice control components, such as aluminum IceStoppers, in bar or rail configurations. These prevent ice from sliding beneath rails, especially on roofs with taller seams.

Select snow retention products that align with your roof's aesthetic.

Pick snow guards with color-matched or powder-coated finishes to blend seamlessly with your roof’s design. Custom finishes may increase lead times, but applying finishes yourself can cut costs and expedite delivery.

Evaluate snow retention solutions designed for roofs with unique shapes.

Standard snow guards may not be suitable for roofs with unusual curves or profiles. Select products specifically designed for these unique applications and, when possible, consult with your roof panel manufacturer for recommendations.

Check local snow load requirements.

Before selecting snow retention products, verify the ground snow load requirements from your local building authority. Pad-style guards usually support up to 45 pounds per square foot; bar and rail systems are better suited for heavier snow loads.

Customize snow guards to fit your roof’s unique design.

Customize snow retention devices to match your roof's unique shape and architectural features for optimal protection.

Schedule adhesive-based snow guard installations during favorable weather.

Plan adhesive-mounted polycarbonate snow guard installations during late spring or early summer when daytime temperatures remain above 50°F. At the same time, water resistance forms within days, and full adhesive curing takes approximately 30 days to complete.

Select snow guards that are compatible with your roof type.

Choose snow retention solutions designed to match your roof's construction and style. Utilize compatibility guides or selection tools to ensure a proper fit and optimal performance.
