Which snow guards are best for Coastal Metal Roofing Supply’s exposed-fastener panels?
Exposed-fastener metal roofs are especially vulnerable to sudden snow and ice slides during the winter months.
These rapid releases, often called rooftop avalanches, happen unexpectedly and can create serious hazards. Metal roof panels feature a smooth, glossy surface. Snow and ice tend to release in large sheets rather than melting off gradually. This rapid movement can put people, pets, and property below the roofline at risk. To reduce these dangers, specialized snow retention systems are available for different roof styles and climate conditions. Our available products range from individual snow guards to rail-style systems. These options are compatible with many slopes and panel designs. Installers and property owners can also rely on detailed guides, blog resources, and updated compatibility charts covering leading roofing brands. Whether the region experiences light flurries or heavy snowfalls, these systems are critical for controlling how snow sheds from the roof.
About Coastal Metal Roofing Supply and Its Exposed-Fastener Panels
Based in Ladson, South Carolina, Coastal Metal Roofing Supply has established itself as a trusted partner for contractors, builders, and homeowners throughout the Lowcountry. CMRS engineers its products to withstand coastal conditions, including heavy rain, salt exposure, and hurricane-force winds. Standing seam panels remain a flagship offering, prized in Charleston and nearby areas for their durability, sleek appearance, and resistance to high winds. Beyond standing seam, Coastal manufactures R-panels and multi-rib panels, giving customers versatile solutions for residential, agricultural, and commercial projects. Each panel is precision-cut to project specifications, minimizing waste and streamlining installation.
Multi-Rib T-Rib
The Multi-Rib (or T-Rib) panel is one of Coastal's most popular exposed-fastener systems. It serves agricultural, residential, and steel-building projects. It features ribs that are ¾ inch high and spaced 9 inches apart, with two subtle reveal-rib grooves that enhance both strength and appearance. Available in 29 and 26-gauge steel, this panel balances versatility with durability. Certifications include UL 2218 Class 4 impact resistance, UL 263 fire rating, and UL 580 Class 90 uplift resistance, making it suitable for demanding conditions. See the Snow Guards Compatibility Chart for Coastal Metal Roofing Supply Multi-Rib T-Rib Screw Down Metal Roofing Panels.
Snow retention options for this profile include polycarbonate guards such as SnoBlox Deuce and SnowBreaker, which fit neatly between minor ribs. Metal solutions, such as SnoCleat PBR and decorative SnowCatchers, can be installed in the flat center section. The Snojax I is designed for screw installation, while the Icejax I can be mounted with either adhesive or screws. For rail-style systems, Tall ColorBrackets with compatible fasteners support ColorBar PBR or SnoBar PBR, providing a secure way to manage snow loads across diverse climates.
R Panel PBR Panel
The R Panel, also known as the PBR Panel, features a bold trapezoidal profile with 36-inch coverage and ribs 1¼ inches high on 12-inch centers. Between the ribs, two low "mesas" add strength and visual appeal. Coastal offers this panel in 24- and 26-gauge steel, with an optional purlin-bearing leg (PBR) for added support. Certifications include UL 2218 Class 4 impact resistance, UL 790 Class A fire rating, UL 263 fire resistance, UL 580 Class 90 uplift resistance, plus approvals from Texas Windstorm and the Florida Building Code. See the Snow Guards Compatibility Chart for Coastal Metal Roofing Supply Multi-Rib T-Rib Screw Down Metal Roofing Panels.
Snow guard compatibility is extensive. Options include SnoBar, ColorBar, SnoCleat PBR, and decorative stainless steel SnowCatchers. Contractors can install polycarbonate guards with screws or adhesive, except for the Snojax I, which requires mechanical fastening. Adhesive applications should use Surebond SB-190, but avoid pairing it with metal pad-style guards. Smaller guards are best centered between the minor ribs. At the same time, straddle models like the Snojax II and Icejax II over either minor rib. Never mount guards or rails on the high ribs; instead, they must be secured through the flat sections into a solid substrate for long-term reliability.
7.2 Panel
The 7.2 Panel is a heavy-duty exposed-fastener system built for architectural, commercial, and industrial projects. It features trapezoidal ribs 1½ inches high, spaced 7.2 inches apart, offering excellent spanning strength. This panel has a minimum gauge requirement of 24. Premium finishes such as PVDF and SMP are available. Certifications include UL 2218 Class 4 impact resistance, UL 790 Class A fire rating, UL 263 fire resistance, and ASTM E 283 air leakage compliance. See the Snow Guards Compatibility Chart for Coastal Metal Roofing Supply 7.2 Screw Down Metal Roofing Panels.
Snow management solutions for this panel include the polycarbonate SnoBlox Deuce and Ecojax, which retain snow and ice on the roof, and the SnowBreaker and SnowBreaker 3M, which fracture snow and ice into safer, smaller pieces as it sheds. These guards can be installed with screws or adhesive, while the SnowBreaker 3M uses double-sided tape. The 7.2 Panel also works with galvanized SnoBar and aluminum ColorBar rail systems. Both rely on the 1.5-inch aluminum Tall ColorBracket for secure installation, ensuring effective snow control.
7/8 Inch Corrugated Panel
The 7/8-inch Corrugated Panel features a classic exposed-fastener design and a deep wave profile. It features ribs 7/8 inch high, spaced 2.67 inches apart, creating a timeless look with structural strength. This panel is available in 22, 24, and 26-gauge options. Certifications include UL 2218 Class 4 impact resistance, UL 790 Class A fire rating, UL 263 fire resistance, and ASTM E 1680 air leakage compliance. See the Snow Guards Compatibility Chart for Coastal Metal Roofing Supply 7/8 Inch Corrugated Screw Down Metal Roofing Panels.
This panel's corrugated shape makes it distinct among exposed-fastener systems. Raised ribs allow snow guards to be mounted directly on the elevated sections, a less common practice in roofing. Popular snow retention choices include the SnoCleat 2.67, secured with 3-inch fasteners, or rail systems like SnoBar and ColorBar, installed with the ColorBracket 2.67. Each bracket has six mounting holes for added strength. While four screws are sufficient in most cases, using all six is recommended in areas with severe weather for maximum durability.
5-V Crimp
The 5-V Crimp panel combines the traditional "old Florida" aesthetic with modern engineering. It features alternating single and double ribs, spaced 12 inches apart, for a distinctive appearance. Coverage is 24 inches, with steel available in 24- and 26-gauge. This system is Miami-Dade County- and Florida Building Code-approved, and Texas Windstorm-certified. It carries UL 2218 Class 4 impact resistance, UL 790 Class A fire rating, UL 263 fire resistance, and UL 580 Class 90 uplift resistance. See the Snow Guards Compatibility Chart for Coastal Metal Roofing Supply 5-V Crimp Screw Down Metal Roofing Panels.
Snow retention options are highly versatile. Stainless steel SnowCatchers are available in decorative designs, including Standard, Sun Burst, Maple Leaf, Fleur-de-lis, Kodiak, and Mustang. Polycarbonate models like SnoBlox Deuce, Icejax II, and SnoBlox Ace can be installed with adhesive or screws, while the Snojax I requires mechanical fastening. For breaking snow into smaller, safer pieces, the SnowBreaker and SnowBreaker 3M are effective solutions. In regions with heavy snow or for those seeking a streamlined look, rail systems such as SnoBar and ColorBar are ideal, installed with Tall ColorBrackets and butyl tape gaskets for added strength and visual appeal.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Coastal Metal Roofing Supply
How Can I Coordinate My Snow Guards with My Roof?
Select finishes that harmonize with your roof’s style and color palette. Powder-coated surfaces or decorative accents can improve aesthetics and help the guards blend naturally. Professional-grade coatings deliver long-lasting protection, while DIY options may offer faster, more affordable customization.
Should I Use Sealant Under My Screw-Mounted Snow Guards?
Placing sealant under screw-fastened polycarbonate guards helps to seal gaps, prevent water penetration, and reduce risks. This added step reinforces the installation and contributes to reliable, long-term performance.
What Snow Guard Solutions Work Best for Unique Roof Shapes?
Roofs with distinctive profiles—such as curved or arched designs—often need specialized snow guard systems. Standard models may not fit correctly, so contractors typically select custom options shaped to the roof’s contours and consult manufacturers for guidance.
When Is the Best Time to Install Adhesive-Mounted Snow Guards?
Adhesive-based snow guards achieve optimal results when installed during warm weather, usually late spring through early summer, with temperatures above 50°F. Heat speeds up curing, while cold slows bonding. Products like SureBond SB-190 typically resist moisture within a day, minimizing weather delays.
How Does Roofing Material Affect Snow Guard Placement?
The roofing type directly influences snow guard spacing and layout. Softer metals such as aluminum or copper often require tighter spacing and multiple rows. At the same time, harder materials like steel allow wider gaps. Always confirm that adhesives and sealants are compatible with the roof surface to avoid bonding or premature corrosion.
Should I Test Fit Snow Guards Before Final Installation?
Performing a dry run before permanent installation helps verify alignment and spacing. This step ensures a precise arrangement, resulting in a neat, professional-looking finish.
How Can I Fasten Snow Guards for Maximum Strength?
For maximum durability, anchor snow guards to structural elements such as rafters or purlins rather than just roof panels. Reinforcing the attachment area boosts load capacity and provides lasting stability.
