See the Snow Guards Compatibility Chart for AB Martin Exposed Fastener Metal Roofing Panels.

AB Martin screw-down metal roof systems often require snow retention solutions tailored to the panel's shape and rib spacing. Below are compatible SnoBlox-Snojax snow guard products and important considerations for these exposed fastener roof panels.

ABM Profile

The ABM Roof Panel is A.B. Martin's flagship metal roofing panel, renowned for its versatility. This all-purpose panel is suitable for residential, commercial, and agricultural roofing and siding applications, making it a popular choice among contractors and homeowners. The ABM Panel is available in two robust steel gauge options to accommodate diverse project requirements. The 28-gauge steel version features a coverage width of 36 inches, with ribs spaced 9 inches apart and a rib height of 3/4 inch. It is offered in a G-100 galvanized substrate, ideal for animal confinement settings, or an AZ-50 Galvalume substrate. With over 25 high-performance color choices, these panels undergo a heat-forming process to ensure superior paint adhesion. An impressive 40-year paint warranty and a 10-year edge rust warranty for the Premium G100 option back the 28-gauge panels. The 26-gauge steel ABM Panel shares the same 36-inch coverage width, 9-inch rib spacing, and 3/4-inch rib height as its 28-gauge counterpart. Constructed with an AZ-50 Galvalume substrate, it offers 15 color options, including nine glare-resistant textured finishes. Like the 28-gauge version, these panels are heat-formed. They can be custom-cut to precise lengths within hours, ensuring efficient project turnaround times. A 40-year paint warranty from the manufacturer backs them up. A.B. Martin designed both gauge options of the ABM Panel with durability, impact resistance, and energy efficiency in mind. Heavy-gauge steel construction contributes to its longevity, while high solar reflectivity helps reduce cooling costs. These 100% recyclable panels are an environmentally friendly choice for metal roofing projects. See the Snow Guards Compatibility Chart for AB Martin ABM Exposed Fastener Metal Roofing Panels.

The ABM Panel is compatible with multiple snow retention options, allowing users to choose between adhesive or screw-based installation methods. The SnoBlox Deuce and SnowBreaker, made of polycarbonate, are suitable for both attachment methods and can be mounted in the center of the panel between the minor ribs. For those preferring to mount a metal snow guard in the center flat of the panel using screws, the SnoCleat PBR and all six SnowCatcher shapes are viable options. Furthermore, the Snojax I and Icejax I can be used with this panel by straddling one of the minor ribs between each 9-inch rib. While the Icejax I is compatible with both adhesive and screws, the Snojax I requires mechanical fastening and is not suitable for adhesive application. Pairing the ABM Panel with Tall ColorBrackets and mechanical fasteners ensures compatibility with aluminum ColorBar PBR and galvanized SnoBar PBR snow rail systems.

When installing snow guards, it is crucial to secure them by screwing down through the low flats of the panel into a sturdy structure for optimal strength. Mounting screw-down individual snow guards or rail systems by screwing them onto the high ribs of a panel is not recommended, as it compromises the installation's strength and effectiveness. For more information on the correct mounting techniques, refer to the recent blog post, "Mounting Snow Guards on the High Ribs or the Panel Flats: Which is Correct?"

PBR Profile

The PBR Roof Panel is a robust and leak-resistant metal roofing system designed for steel-frame and wood-frame structures. This panel features prominent 1-1/4" high major ribs spaced at 12" intervals, with a wide base exceeding 3" for exceptional structural integrity. A unique aspect of the PBR Panel is its purlin-bearing leg, approximately 1" long, which rests on the purlin, providing additional reinforcement and strength. Depending on the gauge, the PBR Panel can span impressive distances without compromising its structural integrity. The 26-gauge panels can span up to 4 feet, while the heavier 24-gauge panels can span up to 5 feet. The PBR Panel offers a range of energy-efficient color choices, providing versatility in aesthetics. The 26-gauge panels have 11 color options with an AZ-50 Galvalume substrate. In contrast, the 24-gauge panels come in Bright White and Galvalume finishes. The panels are custom-made to precise lengths, ensuring a perfect fit for each project. A.B. Martin designed the PBR Panel specifically for roofing applications with roof pitches as low as 1:12, making it stand out from its counterpart, the R Panel, which they primarily intended for sidewall applications. The purlin-bearing leg feature of the PBR Panel provides the necessary support and strength required for roofing installations, making it a reliable choice for both residential and commercial projects. See the Snow Guards Compatibility Chart for AB Martin PBR Exposed Fastener Metal Roofing Panels.

The PBR panel offers remarkable flexibility when installing snow guards, accommodating diverse products. It seamlessly integrates with screw-down options like the SnoBar, ColorBar, and SnoCleat PBR, as well as stainless steel pad-style snow guards such as the Standard Rectangle, Fleur-de-lis, Sun Burst, Maple Leaf, Mustang, and Kodiak models from the SnowCatcher line. For polycarbonate snow guards, most designs can be affixed using either adhesive or mechanical fasteners, except for the Snojax I, which requires screws. Utilizing the Surebond SB-190 adhesive specifically formulated for polycarbonate snow guards is crucial. It is incompatible with metal pad-style guards. When mounting snow guards on the PBR panel, you should install smaller models between the minor ribs in the center of the panels. However, specific guards, like the Snojax II and Icejax II, necessitate off-center mounting, straddling either the left or right minor rib. Consistent placement over the same rib is essential in such cases. It is imperative to avoid directly screwing individual snow guards or rail systems onto the high ribs, as this compromises the integrity and longevity of the attachment. Instead, anchoring the panels to a solid base in the low flats is critical, ensuring maximum installation strength and stability. This approach guarantees the most robust and secure installation for snow guards on the PBR Roof Panel, providing long-lasting protection and peace of mind.

5V Crimp Profile

The 5-V Crimp is a versatile metal roofing panel that combines classic aesthetics and practical functionality. This panel features a 24-inch coverage width and an overall width of 26 inches. It features a distinctive alternating 1-inch by 1/2-inch rib pattern that repeats every 12 inches along its length. One of its standout qualities is the extensive color palette, offering an impressive 50 different hues across galvanized steel and Galvalume substrate materials. This wide range of options allows homeowners and contractors to integrate the panels into their desired design vision seamlessly. These panels are custom-made to order, ensuring precise lengths tailored to each project's requirements. It's important to note that the 5-V Crimp panels are non-returnable due to their custom nature. See the Snow Guards Compatibility Chart for AB Martin 5-V Crimp Exposed Fastener Metal Roofing Panels.

A notable advantage of the 5V roof panel is its compatibility with various snow retention options. Customers can choose from multiple metal screw-down individual pad-style snow guards, such as the stainless steel SnowCatchers available in Standard, Sun Burst, Maple Leaf, Fleur-de-lis, Kodiak, and Mustang shapes. Additionally, the panel is compatible with all polycarbonate pad-style snow guards, including but not limited to the SnoBlox Deuce, Icejax II, and SnoBlox Ace. These polycarbonate models can be installed using screws or adhesive, depending on the desired level of snow and ice retention. The Snojax I is the only polycarbonate snow guard that cannot be installed with adhesive and requires mechanical fasteners. For those who prefer to allow snow and ice to shed from their roofs while slowing it down and breaking it into smaller, safer pieces, the SnowBreaker and SnowBreaker 3M products are suitable options. Alternatively, for a sleek, modern snow retention system ideal for use in areas with high snow loads, the SnoBar and ColorBar snow rail systems may be the preferred choice. These heavy-duty snow fences utilize mechanically fastened Tall ColorBrackets with butyl tape gaskets, providing a robust solution for snow management.

Heritage Profile

The Heritage Panel offers a classic, vintage aesthetic at a cost-effective price compared to traditional standing seam metal roof panels. This exposed fastener panel features 3/4-inch tall ribs spaced 12 inches apart, lending it an old-world, nostalgic appearance. Available in either 28-gauge or 26-gauge steel thickness, the panel provides a coverage width of 36 inches. A notable advantage of the Heritage Panel is its streamlined installation process. Unlike standing seam panels that require specialized seaming equipment, these panels can be directly screwed down to the roof deck, expediting construction timelines. These panels are manufactured to precise custom lengths, minimizing material waste on the job site. While sacrificing some of the handcrafted character of standing seam, the Heritage Panel presents an affordable alternative for achieving a traditional metal roof look through its simple exposed fastener design that demands less skilled labor. A.B. Martin positions this product as a smart choice for budget-conscious projects seeking durability and classic aesthetics. See the Snow Guards Compatibility Chart for AB Martin Heritage Exposed Fastener Metal Roofing Panels.

The Heritage roof panel offers compatibility with various snow retention options, catering to diverse customer needs. Customers can select from metal screw-down individual pad-style snow guards, such as the stainless steel SnowCatchers in Standard, Sun Burst, Maple Leaf, Fleur-de-lis, Kodiak, and Mustang shapes. Furthermore, the panel is compatible with all SnoBlox-Snojax polycarbonate pad-style snow guards, including, but not limited to, the SnoBlox Deuce, Icejax II, and SnoBlox Ace. These polycarbonate models can be installed using screws or adhesive, depending on the desired level of snow and ice retention. It's worth noting that the Snojax I is the only polycarbonate snow guard that cannot be installed with adhesive and requires mechanical fasteners. A thicker application of liquid adhesive or sealant will be required when installing these pad-style guards to compensate for the panel's striations and fill any gaps under the guards. Failure to completely seal below the snow guards can lead to moisture infiltration, which can re-freeze, expand, and cause the guards to dislodge from the panel and fail. For customers who prefer to allow snow and ice to shed from their roofs while slowing it down and breaking it into smaller, safer pieces, the SnowBreaker and SnowBreaker 3M products are suitable options. Alternatively, those seeking a sleek, modern snow retention system or residing in areas with high snow loads may opt for the SnoBar and ColorBar snow rail systems. These heavy-duty snow fences utilize mechanically fastened Tall ColorBrackets with butyl tape gaskets.

Continuous Corrugated Panels: Not Recommended for Roofing

A.B. Martin offers two sizes of wavy, continuous corrugated metal panels. However, they do not recommend using them for roofing purposes. Unlike some other companies that provide similar panels as part of their roofing panel product lines, A.B. Martin does not due, in part, to the "low rib height and lack of an anti-siphon channel." As such, we will not provide snow retention recommendations for these panels.

Six Crucial Considerations Before Installing Snow Guards on Exposed Fastener Metal Roofs

1. Timing for Installing Adhesive-Mounted Snow Guards

You can install screw-down snow guards and rail systems anytime the roof is clear of snow, ice, and debris. However, you need to time the installation correctly for adhesive-mounted snow guards. The SureBond SB-190 adhesive we use for polycarbonate snow guards takes approximately 28 days at 50°F to fully cure. Late spring or early summer is ideal for most of the U.S. and Canada. Temperatures below 50°F won't harm the adhesive, but they will pause the curing process until it warms up again. Rain won't affect the adhesive after 24 hours. One important note: do not use SureBond SB-190 with copper roofing, as the adhesive and metal can react.

2. Preventing Roof Leaks

Products like the SnoCleat PBR, SnoCleat 2.67, SnowCatchers, or screw-down rail systems come with butyl tape gaskets that seal without liquid sealant. When paired with our Master Grippers for wood or Master Drillers for metal, which have neoprene washers for a weather-proof seal, you can avoid roof leaks. Some customers prefer to add liquid silicone around the snow guards for extra protection, but it's not mandatory. If you're screwing polycarbonate snow guards to your roof, use a neutral curing, cold-weather liquid silicone to seal the entire base. Apply enough silicone so that it oozes out around the edges, then run your finger around the perimeter to finish it off. We recommend the NovaFlex MR150 silicone sealant, which we've endorsed for years. Use screws with neoprene washers for these guards.

3. Importance of a Snow Guard Layout

Absolutely! Regardless of the snow retention system you're installing, you should always obtain a design recommendation from the manufacturer. We offer free spacing charts for our products on our website, and we also provide free quote request forms for our snow rail systems and individual snow guards if you need custom layout guidance. Installing snow retention in isolated areas, such as above doorways, HVAC systems, or chimneys, is not recommended.

4. Securing Snow Guards to the Roof Structure

When installing snow guards with screws, it is crucial to ensure that you're screwing into at least 1" of wood structure – this could be plywood decking, purlins, or blocking behind each snow guard or bracket. Mount the snow guards into metal purlins whenever possible for pre-engineered metal buildings. Never install snow guards or rails using only the panel as the structure – it's a recipe for disaster. If you can't easily add blocking under the snow guard mounting points and your ground snow load is 45 psf or less, switch to an adhesive-mounted product instead.

5. Matching Snow Guards to Roof Color

Yes, you can color-match our metal snow guard options in various ways! The SnoCleat PBR, SnoCleat 2.67, and ColorBar Snow Rail Systems come with slide-in color strips you can purchase or create using leftover roofing material for a perfect match. We can also powder coat the SnoCleat, SnoBar, ColorBar, and stainless steel SnowCatcher models to achieve your desired custom color, including unique shades for one-of-a-kind projects. The powder coating ensures the snow guards blend seamlessly with your roofing panels, providing a cohesive look. Please note that we don't stock powder-coated products; we create them specifically for each order, which may take 3–4 weeks, depending on size and color. Suppose you need a faster turnaround or more control over the color. In that case, you can have your snow guards powder coated locally or painted after they arrive.

6. Understanding Ground Snow Load

The ground snow load determines the maximum snow weight your roof can withstand. Weather stations across the U.S. have collected this data for many years. If your project's ground snow load is up to 45 pounds per square foot, you can opt for adhesive-mounted or screw-mounted individual snow guards and bar systems. We recommend snow rail systems for higher loads. You can find the ground snow load for your area by searching online or checking the building plans. If you need assistance, contact your local building inspector or township office for the specific details.
