M-Seam / Standing Seam

Millennium Metals offers two variations of their M-Seam / Standing Seam panels, each designed with durability and visual appeal. The M-Seam Pencil Rib Panel and the M-Seam Striated Panel are snaplock nailstrip panels crafted to meet high quality and performance standards. The M-Seam Pencil Rib Panel has a 16-inch width and 1-inch seam height. It's exclusively manufactured using 26-gauge steel and has various finishes, including acrylic and painted galvalume. Customers can choose from multiple colors, such as Colonial White, Regal Blue, and Patina Green. This panel utilizes the Kynar/Hylar 500 PVDF paint system with a 35-year limited warranty. For those opting for the acrylic galvalume finish, Millenium Metals provides a 25-year limited warranty. The panel meets Florida Building Code requirements and has undergone rigorous UL and ASTM testing to verify its wind uplift resistance. It's compatible with wood decking and can accommodate optional insulation. The M-Seam Striated Panel shares many characteristics with its counterpart, including the 16-inch coverage width and 26-gauge steel construction. It features a snaplock seam design and is available in acrylic galvalume and painted finishes. The color palette includes options like Colonial White, Regal Blue, and Burnished Slate. A key feature of this panel is its striated surface, which helps minimize oil canning. Like the Pencil Rib Panel, it meets Florida Building Code standards and offers excellent wind uplift resistance. The warranty terms are identical, with 35 years for Kynar/Hylar 500 PVDF finishes and 25 years for acrylic galvalume. This panel is suitable for both residential and light commercial applications.

The versatility of these panels is evident in their compatibility with a diverse range of our snow retention solutions, particularly those utilizing adhesive-mounted polycarbonate components. Proper adhesive application prevents moisture-related issues between snow guards and roof panels. Customers can choose from various options, including larger units like IceJax II, Snojax II, and SnoBlox Ace, as well as more compact alternatives such as the Deuce and IceJax I. For enhanced safety during controlled snow and ice release, we recommend the SnowBreaker and SnowBreaker 3M. The panel's unique rib design accommodates clamp-on snow guards, including rail systems such as SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar. While installation typically involves standard stainless steel SnoBar clamps or aluminum RoofClamp alternatives, it is advisable to test-fit a clamp sample before finalizing an order to ensure proper fit and functionality with the specific panel design.

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

Analyze Snow Load Requirements

Assess your area's Ground Snow Load to guide your snow retention system selection. Individual pad-style guards are typically sufficient for regions with snow loads up to 45 psf. Heavier snowfall areas require more substantial rail systems. Seek expert advice from panel manufacturers for roofs unsuitable for snow rails or in areas with ground snow loads exceeding 45 psf.

Design a Comprehensive Layout

Create a holistic snow retention plan covering the entire roof area, usually incorporating multiple ascending rows for even load distribution. Arrange individual pad-style snow guards in a zigzag staggered pattern and snow rails in straight lines. Avoid isolated installations above exits, walkways, or architectural elements to prevent system overload. Utilize our available resources, spacing guides, and custom quote forms to optimize your design.

Verify Component Compatibility

Before full implementation, ensure compatibility of chosen snow retention components. We suggest testing samples of our snow guards, clamps, brackets, or fittings on your roof type. This precautionary step helps avoid costly mistakes and ensures optimal system integration.

Manage Ice Formation

For standing seam roofs with rail systems, consider adding IceStopper ice management attachments, especially above high-traffic pedestrian areas. These can be installed initially or added later. Proper spacing is crucial to prevent ice from sliding under the bar, mainly for seams taller than 1 inch.

Follow Proper Installation Protocols

Avoid directly attaching snow guards or rails to standing seam metal roofs using penetrating fasteners. This incorrect method often leads to panel damage, compromised weatherproofing, and expensive repairs due to natural thermal expansion and contraction. Instead, clamp-on or adhesive-mounted systems ensure compatibility and maintain warranty validity.

Time Installation Optimally

Plan installation during late spring or early summer for adhesive-mounted polycarbonate snow guards. Our recommended adhesive, Surebond SB-190, needs about 28 days at 50°F (10°C) to fully cure, with rain resistance developing after approximately 24 hours.

Integrate Aesthetically Pleasing Finishes

Match snow retention system colors to enhance your roof's visual appeal. Some products offer optional, adaptable metal inserts that match your roof color or create contrasts. These can be purchased with snow guards or made on-site using extra roofing material. For precise color matching, consider optional full-coverage powder coating services. You can explore DIY painting or local powder coating options for greater color control or faster processing.
