Which snow retention systems are best suited for ADCO Metals’ exposed-fastener roofing?
Metal roofs with exposed fasteners are especially vulnerable to sudden sheets of snow and ice sliding off in winter, often referred to as rooftop avalanches.
Due to the smooth surface of these panels, snow and ice can release all at once as roof avalanches, posing a risk to people, pets, and property below. To address these hazards, we offer customized snow retention solutions specifically designed for various roof profiles and climate conditions. Options include both individual snow guards and rail-style systems that adapt to a wide range of slopes and panel types. To support installers and property owners, we also supply detailed manuals, blog resources, and updated compatibility charts for leading roofing brands. In areas with light or heavy snowfall, these systems are critical for safely managing how and when snow sheds from the roof.

Corrugated Panel
ADCO's corrugated panels, available in 29 and 26-gauge steel, are a durable option for both roofing and siding. Each panel delivers 24 inches of coverage and features the classic wave-like corrugations that efficiently direct water away from the roof. The continuous rib spacing enhances weather resistance while maintaining a timeless aesthetic. Known for their longevity, these panels can last between 25 and 60 years, depending on the installation and substrate. Performance certifications include UL 790 Class A fire resistance and UL 2218 impact resistance, offering protection against fire and hail. Customers also benefit from warranties of up to 40 years on painted finishes and 25 years on Acrylic Coated Galvalume, ensuring long-term value and peace of mind. See the Snow Guards Compatibility Chart for ADCO Metals Corrugated Screw Down Metal Roofing Panels.
This panel's distinctive corrugated profile makes it unique among exposed-fastener systems. Raised ribs allow snow guards to be mounted directly on the elevated sections, which is less common in roofing applications. For snow retention, popular solutions include the SnoCleat 2.67, secured with 3-inch fasteners, or rail systems such as SnoBar and ColorBar, both of which contractors can install with the ColorBracket 2.67. Each bracket features six mounting holes for added strength and stability. While four screws are sufficient for most installations, using all six is recommended in regions with severe weather for maximum durability.
5-V Panel
The 5-V panel blends traditional style with modern performance. Manufactured in 24 and 26-gauge steel, it provides 24 inches of coverage. It is defined by five distinctive "V" ribs, each about three-quarters of an inch high. This design enhances leak resistance while offering a classic appearance, making it a popular choice for residential and agricultural buildings. The panel meets UL 2218 Class 4 impact resistance, UL 790 Class A fire rating, and UL 580 Class 90 wind uplift standards. It also carries approvals under the Florida Building Code and Miami-Dade County NOA, certifying it for hurricane-prone regions. With warranties of up to 40 years on painted finishes and 25 years on Acrylic Coated Galvalume, the 5-V panel delivers both beauty and reliability. See the Snow Guards Compatibility Chart for ADCO Metals 5-V Screw Down Metal Roofing Panels.
Snow retention options for this panel are versatile. It supports pad-style guards such as stainless steel SnowCatchers in designs like Standard, Sun Burst, Maple Leaf, Fleur-de-lis, Kodiak, and Mustang. Polycarbonate models, including SnoBlox Deuce, Icejax II, and SnoBlox Ace, can be installed with adhesive or screws, while the Snojax I requires mechanical fastening only. For breaking snow into smaller, safer pieces, the SnowBreaker and SnowBreaker 3M are effective solutions. In areas with heavy snow loads or for those who prefer a sleek, modern look, rail systems like SnoBar and ColorBar are ideal, installed with Tall ColorBrackets and butyl tape gaskets for added strength and aesthetics.
PBR Panel
Designed for strength and adaptability, contractors use the PBR panel in commercial, industrial, and agricultural projects. Standard production is available in 26-gauge steel, with options also available in 29-gauge and 24-gauge steel. Each panel covers 36 inches and features ribs 1.25 inches high, spaced 12 inches apart, allowing spans of up to five feet. This design reduces material costs while maintaining structural integrity. Certifications include UL 2218 Class 4 impact resistance, UL 790 Class A fire rating, UL 580 Class 90 wind uplift resistance, ASTM E1592 structural performance, and Texas Windstorm approval. Like other ADCO panels, the PBR comes with warranties of up to 40 years on painted finishes and 25 years on Acrylic Coated Galvalume. See the Snow Guards Compatibility Chart for ADCO Metals PBR Screw Down Metal Roofing Panels.
Snow guard compatibility is broad, with options such as 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. For adhesive applications, use Surebond SB-190, but avoid pairing it with metal pad-style guards. Center smaller guards between minor ribs. Position models like Snojax II and Icejax II on either side of the rib. Never mount guards and rails on the high ribs; instead, secure them through the flat sections into a solid substrate to ensure lasting performance.
SM-Panel
ADCO's SM-Panel, designed for residential roofing and siding, offers both affordability and durability. The panel provides 36 inches of coverage and features five ribs spaced nine inches apart, each measuring three-quarters of an inch in height. Manufacturers produce the panel in 29- and 26-gauge steel with either Galvalume or galvanized substrates. An integrated anti-siphon channel improves weather resistance, making it a dependable choice for homes and post-frame buildings. Certifications include a UL 790 Class A fire rating, UL 2218 impact resistance, and approval from the Florida Building Code. Warranties extend up to 40 years on painted finishes and 25 years on Acrylic Coated Galvalume. See the Snow Guards Compatibility Chart for ADCO Metals SM Screw Down Metal Roofing Panels.
Snow retention solutions for the SM-Panel include polycarbonate guards, such as SnoBlox Deuce and SnowBreaker, which fit between the minor ribs. Install metal options such as SnoCleat PBR and decorative SnowCatchers in the flat center section. Choose the Snojax I for screw installation, or mount the Icejax I with adhesive or screws. For rail systems, Tall ColorBrackets paired with compatible fasteners support ColorBar PBR or SnoBar PBR, offering a strong and reliable solution for managing snow loads in diverse climates.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by ADCO
When Is the Best Time to Install Adhesive-Mounted Snow Guards?
Installers achieve the best results with adhesive snow guards when they apply them in warm weather, typically from late spring to early summer when temperatures exceed 50°F. Heat speeds up the curing process, while colder temperatures may hinder proper bonding. Adhesives, such as SureBond SB-190, typically resist moisture within 24 hours, minimizing weather-related setbacks.
Should I Apply Sealant Under Screw-Mounted Snow Guards?
Applying a generous layer of sealant beneath screw-attached polycarbonate snow guards helps seal gaps, reduce water intrusion, and prevent leaks. This additional protection reinforces the installation and contributes to long-term performance.
How Can I Coordinate Snow Guard Finishes with My Roof Design?
Select finishes that harmonize with your roof's color palette and architectural style. Powder-coated finishes or decorative inserts can elevate curb appeal and help the guards blend into the roofline. Professional coatings offer lasting durability, but DIY options may deliver quicker results at a lower cost.
How Can I Fasten Snow Guards for Maximum Strength?
To ensure maximum holding power, attach snow guards to structural elements, such as rafters or purlins, rather than just the roof panels. Reinforcing the mounting area can improve load capacity and long-term stability.
Should I Test Fit Snow Guards Before Final Installation?
Pre-fitting snow guards allows you to confirm proper spacing and alignment before final attachment. This step helps fine-tune placement and ensures a clean, professional-looking result.
What Snow Guard Solutions Work Best for Unique Roof Shapes?
Roofs with unconventional shapes, such as those with curved or arched profiles, often require custom snow guard solutions. Standard models may not fit correctly, so it is advisable to choose guards designed for your roof's specific contours and consult the manufacturer for guidance on the best fit.
How Does Roofing Material Affect Snow Guard Placement?
The type of roofing plays a key role in determining snow guard spacing and layout. Softer metals, such as copper or aluminum, may require tighter spacing and multiple rows, whereas harder materials, like steel, can support wider gaps. Always verify that adhesives and sealants are compatible with your roofing material to prevent bonding issues.
