Snow Guards for Star Building Systems
Snow guards for Star Building Systems roofing panels help control sudden rooftop snow and ice movement above walkways, entrances, parking areas, landscaping, equipment, and other vulnerable locations. The correct SnoBlox-Snojax system depends first on whether the roof is a standing-seam concealed-fastener system or an exposed-fastener panel, then on the specific Star panel profile.
- Star standing-seam and exposed-fastener panels require different attachment methods.
- Standing seam panels should use compatible clamp-on systems or adhesive-mounted guards, never screw-down attachments through the concealed-fastener panels.
- PBR and PBU exposed-fastener panels accept selected pad-style guards and PBR rail systems.
- PBC and PBD profiles use snow retention made for 2.67-inch corrugated geometry.
- Final selection should account for slope, panel width, roof run, material, snow load, surface configuration, and a complete layout.

About Star Building Systems Roofing Systems
Star Building Systems traces its history to 1927, when the company began supplying small structures for Oklahoma oil-field operations. It has since grown into a manufacturer of custom-engineered commercial and industrial building systems. Now part of Cornerstone Building Brands, Star offers both concealed-fastener standing-seam roofs and exposed-fastener metal panels. Because these profiles differ substantially, snow retention must match the exact panel installed.
Snow Retention Solutions for Star Building Systems Roofing
Star standing-seam and exposed-fastener roofs do not share a single universal attachment method. Compatible standing-seam roofs can use non-penetrating clamps attached to the seam or adhesive-mounted polycarbonate guards bonded to a suitable flat pan. Exposed-fastener panels may require adhesive bonding, mechanical fastening through designated low-flat areas, PBR brackets, or 2.67 corrugated brackets.
Explore our complete selection of snow guards for metal roofs and use the two charts below to verify compatibility. “YES” identifies a listed fit for that panel. “NO” indicates that the product is not shown as compatible with that profile.
Snow Guards for Star Building Systems Standing-Seam Roof Panels
This guide covers Ultra-Dek, Double-Lok, SuperLok, and BattenLok HS. Ultra-Dek and Double-Lok have 3-inch trapezoidal seams, while SuperLok and BattenLok HS use 2-inch seams. All four profiles support the adhesive and clamp-on options listed in the chart when installation conditions are suitable.
Standing-seam warning: Never use screw-down snow guards on these concealed-fastener panels. Use an approved clamp-on system after confirming seam fit, or choose adhesive-mounted guards where the panel provides a clean, flat bonding surface.

All four standing seam profiles shown are broadly compatible with adhesive-mounted polycarbonate guards and non-penetrating clamp-on systems. Order a clamp sample and test-fit it before purchasing a complete clamp-on system.
Some striated pans require additional adhesive to fill small surface gaps. Aluminum and copper panels may need more rail rows than comparable steel roofs because the panel material is less rigid. Do not use adhesive-mounted guards on copper roofing.
Snow Guards for Star Building Systems Exposed Fastener Roof Panels
The exposed-fastener section covers PBR, PBC, PBD, and PBU. PBR provides wide low flats for approved pad-style products and PBR brackets. PBC and PBD use 2.67-inch rib spacing and require products designed for that geometry. PBU has narrower low-flat mounting areas, which limits compatible pad-style choices but still permits selected PBR rail systems.
Exposed fastener reminder: On PBR and PBU, compatible screw-down products must mount in the designated low-flat areas and fasten into adequate structure. Do not place these products on the high ribs. PBC and PBD are exceptions: their compatible 2.67 systems fasten to the high ribs with the specified brackets and fasteners.

PBR works with the broad group of pad-style guards and PBR rail products shown. IceJax II and SnoJax II must be positioned consistently off-center to straddle the same minor rib or mesa. Smaller compatible guards generally fit between minor ribs near the panel center.
PBC and PBD accept only the listed 2.67 corrugated products. PBU's narrow flat areas accommodate IceJax I, Ecojax, SnoBlox Deuce, SnoBlox Ace, and SnowBreaker, plus the listed PBR cleat and rail systems.
Star Building Systems Snow Guard Buying Checklist
- Confirm the exact Star Building Systems panel name before choosing a product.
- Identify the roof type: standing seam, concealed fastener, exposed fastener, PBR-style, or 2.67 corrugated.
- Verify the attachment method: adhesive, screw-down, clamp-on, PBR bracket, or 2.67 corrugated bracket.
- Check the ground snow load. Individual pad-style guards are generally best suited to lighter snow-load applications. For ground snow loads greater than 45 psf, we typically recommend a continuous rail system.
- Request a layout instead of protecting only isolated areas such as doors, chimneys, or equipment.
- Order samples or single units when you need a test fit. SnoBlox-Snojax products and components are available without a minimum order.

Compatibility Guidance Note
SnoBlox-Snojax bases the compatibility information presented in this guide on product testing and field experience with Star Building Systems metal roof panel profiles. Panel manufacturers periodically update profile specifications, and individual project variables, such as seam condition, coating type, and installation method, can affect outcomes. Customers are encouraged to confirm current panel specifications directly with Star Building Systems and to contact SnoBlox-Snojax with project-specific questions before ordering.
Snow Guards for Star Building Systems Metal Roofing Panels – Compatibility & Installation FAQ
Use SureBond SB-190 adhesive for compatible glue-down polycarbonate snow guards. It requires about 28 days at temperatures of 50°F or higher to fully cure.
Install compatible screw-down guards and rail brackets through the designated low-flat areas, and fasten them into adequate structure beneath the panel. Do not attach them only to the roof sheet or mount them on the high ribs.
Yes. Install snow guards according to a complete layout that distributes the snow load across the roof. Installing products only above doors, walkways, or isolated areas can overload the system and lead to failure.
Compare the panel shape, rib spacing, seam height, and coverage width with Star Building Systems specifications and the panel descriptions in our detailed blogs. If you are still unsure, order a single product or clamp for a test fit, or contact SnoBlox-Snojax for assistance.
