Fall Protection Strategies For Imetco Standing Seam Roofs

See the Roof Anchor Compatibility Chart for IMETCO Standing Seam Panels.

Who Is IMETCO?

Since 1994, IMETCO (Innovative Metals Company, Inc.) has been a driving force in the high-performance building envelope industry. Based in Norcross, Georgia, they have built a reputation for engineering metal roof and wall systems that handle the most extreme environmental loads while maintaining a high-end architectural aesthetic.

Imetco acquired Martin Fireproofing in 2015. This strategic move allowed IMETCO to become one of the first manufacturers to offer a truly integrated, engineered roofing assembly. As a 100% employee-owned company, they maintain a hands-on approach to engineering, producing roof panels, decking, rain screens, retrofit framing, and sound management systems.

Non-Penetrating Fall Protection is Critical for IMETCO Standing Seam Roofs

IMETCO systems, such as the Series 300 and ZIP-RIB, use concealed fasteners and floating clips to allow panels to expand and contract with changing temperatures.

If you use traditional penetrating anchors that screw through the panel and into the deck, you are effectively "pinning" the roof. Older anchoring methods can create structural stress, leading to unappealing "oil-canning" or buckling, hidden water leaks, and almost certainly voiding that valuable roof warranty.

The goal here is simple: protect the worker without compromising the roof system. In 2026, the only way to achieve both is with non-penetrating fall protection. Using non-penetrating anchors maintains the building's weathertight integrity while remaining fully compliant with OSHA regulations. The two most popular non-penetrating anchor methods include seam-mounted and ridge-mounted anchors.

The SSRA Component System For Imetco Panels

The Standing Seam Roof Anchor (SSRA) product line is the most versatile solution for IMETCO profiles because it is a modular system that scales from a simple tie-off point to a full-blown horizontal lifeline. The foundation of this system is the SSRA1 Seam Anchor. Weighing only 4.5 lbs, this is the lightest 5,000-lb certified anchor on the market. It uses a patented design with 12 stainless steel set screws to grip the seam without the need for bulky, damaging compression plates. It's compatible with over 500 profiles, making it the primary choice for IMETCO's flagship steel panels. The SSRA1 has a removable D-ring that allows workers to attach various adapter plates for expanded functionality.

For standard 22-gauge steel IMETCO panels, you have the choice of cupped-tip stainless steel set screws torqued to 90 in-lbs or nylon-tip set screws torqued to 180-200 in-lbs. For 24-gauge steel panels, use the nylon-tipped set screws with 180-200 in-lbs of torque. 

If your crew needs to stage materials or create a level working platform on a steep roof, the SSRA2 Adjustable Roof Jack Adapter is the answer. These adapters mount directly to the SSRA1 seam anchors with the D-ring removed, supporting 10-foot 2x10 wooden walkboards. They are fully adjustable for pitches between 6:12 and 12:12, giving you a level work platform without roof penetrations. For projects requiring increased worker mobility, the SSRA3 Anchor Plate attaches to two SSRA1 anchors. This assembly creates a mounting solution tested to over 10,000 lbs, serving as the attachment point for horizontal lifelines.

Horizontal Lifeline (HLL) Solutions

For roof pitches up to 4:12, horizontal lifelines provide maximum worker mobility. For continuous protection across standing seam roofs, we offer two distinct HLL configurations. The 100' SSRA HLL Kit is perfect for temporary installation. It includes four SSRA1 anchors, two SSRA3 plates, and a 100-foot kernmantle rope. It's designed for quick deployment and removal, allowing two workers to remain 100% tied off while navigating the roof. For facilities that require regular maintenance access, the 120' Super Anchor Kit is the permanent choice. It utilizes a 3/8-inch galvanized steel cable with a tensile strength of 14,000 lb. The 5-inch riser posts and non-penetrating seam clamps provide a long-term safety solution without penetrations.

Keep in mind that OSHA 1926.501(b)(11) limits horizontal lifeline systems to a maximum pitch of 4:12. Anything steeper is classified as a "Steep Roof" by OSHA. As the roof pitch increases, workers have fewer anchorage options, requiring stronger anchors for work on steeper roofs. OSHA recognizes that workers can lose their footing and slide on steeper roofs, leading to dangerous swing falls and increased fall arrest loads that are not suitable for horizontal lifeline setups.

The Ridge Pro: The Steep Roof Solution For Imetco Roofs

The Ridge Pro Steep Assist becomes an indispensable alternative for steep IMETCO projects. The Ridge Pro provides a "first-man-up" anchor point that secures over the ridge. By using the Ridge Pro for these steeper applications, you remain fully compliant with OSHA’s more stringent steep-roof requirements while ensuring your crew has stable, secure access from the moment they transition from the ladder to the roof.

The Ridge Pro Steep Assist is an excellent non-penetrating anchor solution for lighter-gauge roof panels. Instead of clamping onto the seams of an aluminum or copper roof, the Ridge Pro hooks securely over the roof peak. This option uses the roof's structural stability to provide a reliable anchor point. It is an excellent option for roofs with pitches between 6:12 and 12:12. Using the Ridge Pro on these softer substrates eliminates the need to attach anything to the seams.

ZIP-RIB™ Structural Bulb Panel (SSRA Compatible)

The IMETCO ZIP-RIB is a popular structural panel designed for high-performance applications on slopes as shallow as 1/4:12. These panels are typically available in 12, 16, and 18-inch widths. However, IMETCO can produce custom widths up to 22 inches for specific project requirements.

What makes the ZIP-RIB system a favorite for complex architectural projects is its extreme versatility in manufacturing. It can be produced in continuous lengths exceeding 460 feet, removing the need for end laps on long panel runs. It also supports architectural designs like conical tapers and both convex and concave curves. Whether the project involves plywood, metal decking, re-roof framing, or even installation over open purlins, the ZIP-RIB adapts to the structure. You'll find it fabricated in everything from 18-, 20-, 22- and 24-gauge steel to aluminum, copper, zinc, and stainless steel. See the Roof Anchor Compatibility Chart for IMETCO 22 Gauge and 24 Gauge ZIP-RIB Structural Bulb Standing Seam Panels.

Fall Protection for ZIP-RIB Panels

Because the ZIP-RIB uses a tall, bulb-style seam, you need fall protection that provides enough clearance to grip the vertical leg without crushing the bulb or interfering with the mechanical lock.

For crews working on non-curved 22 and 24-gauge galvanized steel, the SSRA1 Seam Anchor is the ideal non-penetrating solution. These anchors serve as the foundation for your entire safety setup, providing a certified 5,000 lb. tie-off point.

When the job requires material staging or stable footing, the SSRA2 Adjustable Roof Jacks mount directly to the SSRA1 anchors to support 10-foot walkboards. For larger roof systems, workers can mount SSRA3 Anchor Plates atop two SSRA1 anchors. This assembly serves as the foundation for the SSRA HLL 100-foot temporary HLL kit. For more permanent safety solutions, the Super Anchor 120-foot permanent horizontal lifeline kit uses galvanized steel cable and 5-inch riser posts to protect workers for decades. These systems ensure that multiple workers can move freely across the ZIP-RIB surface while remaining 100% tied off at all times.

For aluminum, zinc, or copper ZIP-RIB panels with 6:12 to 12:12 pitch, the Ridge Pro Steep Assist is the best choice. Since softer architectural metals can be sensitive to the high torque required for seam-mounted clamps, the Ridge Pro hooks over the roof peak instead. This strategy provides immediate, secure access from the moment a worker leaves the ladder, relying on the roof's structural stability rather than the panel seams.

It is important to note that curved ZIP-RIB panels pose unique challenges for attaching fall protection anchors. Because of variable angles and the potential for swing-fall hazards, we do not recommend using the standard SSRA system or the Ridge Pro on curved sections. These specific applications require an on-site inspection by a trained safety professional to determine the most effective fall protection strategy. Taking this step ensures you are protecting both your crew and the IMETCO system's sophisticated design.

Series 300® Symmetrical T-Panel (SSRA Compatible)

IMETCO's Series 300 is a structural standing seam panel, engineered to deliver decades of weathertight performance. What makes this system truly unique is its symmetrical 2⅜-inch tall seam.

Because the panel legs are identical, the snap-on seam cap simplifies installation and allows for individual panel replacement. The design utilizes a one-piece clip that facilitates "unlimited" thermal movement. See the Roof Anchor Compatibility Chart for IMETCO 22 Gauge and 24 Gauge Series 300 Symmetrical T-Panel Standing Seam Panels.

This panel is one of the most rigorously tested systems on the market. It has passed the ASTM E-1592 for wind uplift and FM 4471 for fire, wind, and impact resistance. Whether it's installed on a shallow 1/4:12 pitch or as a vertical wall panel, the Series 300 handles the load. It's available in 12, 16, and 18-inch widths and can be 20, 22, or 24-gauge steel, heavy-duty .063" aluminum, zinc, copper, or stainless steel. For high-end architectural designs, it can even be tapered or field-curved into convex, concave, or even "S"- shaped forms.

Fall Protection for Series 300 Panels

For non-curved 22 and 24-gauge steel installations, the SSRA1 Seam Anchor is the foundation of the SSRA component system. By clamping securely to the vertical legs of the seam, these anchors provide a 5,000 lb. tie-off point that won't interfere with the panel's thermal expansion.

If you need to stage tools or materials, the SSRA2 Adjustable Roof Jacks mount directly to the anchors to create level 2x10 walkboards.

For larger crews, the SSRA3 Anchor Plates allow you to run the SSRA HLL 100-foot temporary horizontal lifeline with a kernmantle rope, providing worker protection for short-term projects. For permanent lifelines, the 120-foot Super Anchor kit utilizes five riser posts and non-penetrating clamps to secure the system without piercing the metal. This heavy-duty hardware supports a 120-foot galvanized steel cable, ensuring decades of rooftop safety and maintenance access.

For panels made from aluminum, zinc, copper, or stainless steel, or for projects with a steep pitch of 6:12 to 12:12, the Ridge Pro provides a safer alternative by hooking over the ridge. This device ensures 100% tie-off from the moment the user steps onto the roof.

The changing panel shapes of a curved roof can create unpredictable swing-fall hazards that are incompatible with standard seam anchors. For curved roof systems, an on-site inspection by a qualified safety professional is mandatory. They will help you engineer a custom fall protection plan that keeps your workers safe.

TwinLok™ Mechanical Panel (SSRA Compatible)

The TwinLok panel is a mechanically double-locked standing seam system engineered for long-term durability on slopes of 2:12 and above. With seam height options of 1.5 or 2 inches, it is a versatile choice for architectural designs that demand a traditional, robust profile.

Architects can customize the panel with either a striated or flat design in 12, 16, or 18-inch widths. This system can survive extreme weather, backed by rigorous testing including UL-580 Class 90 windstorm ratings and ASTM E-1592 for uniform static air pressure. Fabricated in 22 and 24-gauge steel, as well as aluminum and zinc, the TwinLok panel is designed for the long haul, often carrying a 20-year Kynar® finish warranty and specialized weathertight warranties on qualified projects. See the Roof Anchor Compatibility Chart for IMETCO 22 Gauge and 24 Gauge TwinLok Mechanical Standing Seam Panels.

Fall Protection for TwinLok Panels

For 22 and 24-gauge steel TwinLok profiles, the SSRA1 Seam Anchor is the standard for secure, clamp-on fall protection. These anchors provide a certified 5,000 lb. tie-off point without piercing the double-locked seams, ensuring the roof's warranty and performance remain intact.

For staging materials or creating a level workspace, the SSRA2 Adjustable Roof Jacks mount directly to the SSRA1 anchors to support 10-foot walkboards. For temporary installation or maintenance, the 100-foot SSRA HLL Kit uses SSRA3 Anchor Plates to bridge two SSRA1 anchors, creating a temporary horizontal lifeline. For buildings requiring permanent maintenance access, the 120-foot Super Anchor Permanent HLL Kit is the superior choice. This permanent system bypasses the SSRA3 plates entirely, utilizing its own non-penetrating seam anchors and 5-inch riser posts to keep the galvanized steel cable elevated above the TwinLok seams.

If your TwinLok project features aluminum or zinc panels, or if the roof pitch is between 6:12 and 12:12, the Ridge Pro Steep Assist is required. Because softer panel materials are not compatible with seam-mounted anchors, the Ridge Pro hooks over the roof peak to leverage the ridge's structural stability. This ridge anchor provides immediate 100% tie-off from the second a worker leaves the ladder, ensuring the roof remains pristine and the crew remains protected.

PermLok™ Snaplock Panel (SSRA Compatible)

IMETCO's PermLok series is a high-performance snaplock system that delivers a clean, architectural look without sacrificing structural strength. Available in both 1.0-inch and 1.5-inch seam heights, this panel is a good choice for high-slope roofing applications featuring a pitch of 3:12 or greater.

The PermLok 1.0 is available in 13- and 17-inch widths, while the PermLok 1.5 is available in 12- and 18-inch widths. Like the rest of the IMETCO family, these panels are incredibly versatile. They can transition seamlessly from the roof to vertical wall applications. See the Roof Anchor Compatibility Chart for IMETCO 22 Gauge and 24 Gauge PermLok SnaplockStanding Seam Panels.

PermLok is engineered with heavy 18-gauge concealed clips and factory-installed seam sealant to ensure it remains watertight and secure under pressure. It has earned its stripes in the lab, passing UL-580 Class 90 windstorm testing and rigorous ASTM standards for air and water penetration. Typically fabricated from durable 22 or 24-gauge steel or architectural aluminum in .032" or .040" thicknesses.

Fall Protection for PermLok Panels

Because PermLok is a snaplock system, using the appropriate non-penetrating anchors is vital to avoid seam damage. For 22 and 24-gauge steel installations, the SSRA1 Seam Anchor, SSRA2 Adjustable Roof Jacks, and SSRA3 Anchor Plates provide the most compatible safety solution.

The SSRA1 anchors attach securely along the panel seams, providing a certified 5,000 lb. tie-off point that won't compromise the roof's structural "floating" design. For staging tools or materials, the SSRA2 Adjustable Roof Jacks mount directly to the anchors to support level walkboards on steep slopes.

When it comes to horizontal lifelines, the choice depends on the project's duration. For temporary installations, the 100-foot SSRA HLL Kit is the best option. It uses the SSRA3 Anchor Plates and two SSRA1 anchors, providing a high-strength mounting point for a temporary kernmantle rope system that keeps multiple workers safely tied off.

If the facility requires permanent access for long-term maintenance, you should opt for the 120-foot Super Anchor Permanent HLL Kit. This system is specifically designed for long-term attachment with its own specialized non-penetrating seam anchors and 5-inch riser posts to keep the galvanized steel cable elevated above the PermLok seams. This assembly ensures the line is always ready for use without interfering with the roof's ability to shed water or manage thermal movement.

For PermLok roofs made from aluminum, or for any project with a steep slope between 6:12 and 12:12, the Ridge Pro Steep Assist is a much better option. Since you want to avoid attaching to softer architectural metals, the Ridge Pro hooks over the roof peak. This solution ensures 100% worker tie-off from the moment they leave the ladder while avoiding seam attachment on the PermLok panels.

Batten-Tite™ Panel (Ridge Pro Only)

The Batten-Tite panel is IMETCO's premium architectural batten system. With a seam height of 1-7/8 inches and custom widths up to 44-1/2 inches, it's available in 20, 22, and 24-gauge steel, as well as aluminum, zinc, and copper.

This system is a rugged panel system that has been thoroughly tested for structural integrity under wind pressure (ASTM E330) and water penetration (ASTM E331). It carries a 20-year Kynar® finish warranty and is often eligible for weathertight warranties. Installation crews can curve Batten-Tite panels to meet advanced architectural designs. However, curved standing seam roofs pose unique challenges for securing fall protection anchors. See the Roof Anchor Compatibility Chart for IMETCO Batten-Tite Standing Seam Panels.

Fall Protection for Batten-Tite Panels

When it comes to fall protection on a Batten-Tite roof, this panel is not compatible with the SSRA product line. The width and shape of the batten cap prevent seam-mounted anchors from achieving the necessary grip without damaging the architectural profile.

For non-curved roofs with a slope between 6:12 and 12:12, the Ridge Pro Steep Assist is the only recommended solution. The Ridge Pro hooks securely over the roof peak with the help of a lightweight extension pole. This assembly provides a reliable tie-off point that protects the worker while they are on the roof.

As with all specialized IMETCO systems, curved Batten-Tite panels require additional expertise in fall protection. Neither the SSRA products nor the Ridge Pro are compatible with curved metal roofs unless a trained safety expert has performed a comprehensive on-site inspection and authorized the setup. Taking this step is the only way to ensure the fall arrest strategy accounts for the building's specific design.

SS Panel Batten-Cover Seam (Ridge Pro Only)

The IMETCO SS Panel features a 1-inch snap-on seam cap. This symmetrical design is a favorite for contractors because it simplifies complex miter cuts at valleys, hips, and dormers, significantly boosting installation efficiency.

To ensure top-tier weather resistance, the seam cap features factory-installed sealant that provides a robust barrier against water infiltration. Designed for installation over a solid substrate with high-quality underlayment, the SS Panel requires a minimum pitch of 3:12. It is available in standard widths of 12, 14, 16, and 18 inches and is typically fabricated from 22 or 24-gauge galvanized steel or .032/.040 aluminum. See the Roof Anchor Compatibility Chart for IMETCO SS Panel Batten-Cover Standing Seam Panels.

The SS Panel can be tapered or curved by installation crews to fit creative architectural designs. It also carries a 20-year finish warranty, ensuring that the roof maintains its aesthetic appeal while performing in demanding environments. Whether the project is a straightforward residential roof or a complex commercial build, the SS Panel provides a reliable, symmetrical solution that balances ease of installation with long-term durability.

Fall Protection for SS Panel (Snaplock)

The SS Panel system is not compatible with SSRA products due to its batten-cover design.

However, the Ridge Pro allows you to bypass the seams entirely by hooking securely over the roof peak on non-curved panels. This option gives your crew a reliable, non-penetrating tie-off point from the moment they step off the ladder. Using this system ensures that you are following OSHA standards and keeping your workers 100% tied off without risking damage to the symmetrical snap-on caps or the weathertight sealant inside them.

It is also important to remember that curved SS Panel installations add a layer of complexity to any fall protection plan. Generally, standard SSRA and Ridge Pro products are not suitable for curved sections due to the variable angles and swing-fall risks involved. For any curved roof, a thorough on-site inspection by a trained safety professional is a mandatory step to establish a specialized strategy that protects both the workers and the integrity of the curved metal.

10 Bonus Metal Roof Safety Tips for You and Your Crew

Staying safe on an IMETCO roof requires more than just the proper anchors; it requires a total commitment to safety culture. Here are ten essential strategies to keep your team protected while preserving the integrity of these high-performance systems.

Take Precautions for Curved Metal Panels

Seam-mounted anchors are generally not compatible with curved panels. Always consult with a fall protection specialist to develop a custom plan that accounts for the building's unique design.

Establish OSHA-Compliant Safety Plans

Before anyone even puts on a harness, a thorough safety plan is critical for keeping the project moving forward safely. An OSHA-compliant safety plan defines tie-off anchor and lifeline locations and details exactly how fellow workers will perform a rescue if someone falls.

Utilize Specialized Roof Anchor Systems

On an IMETCO roof, you need systems designed to clamp onto the rib without piercing the metal. Avoid selecting seam anchors that must be mounted on top of hidden clips, as these are nearly impossible to locate on existing roofs.

Implement Permanent Roof Anchor Systems

Permanent lifeline systems are a wise investment for roofs that will require routine maintenance throughout their lifespans. Installing a galvanized cable system, such as the Super Anchor 120-foot Permanent HLL kit, provides a "ready-to-use" safety solution that stays in place to protect maintenance workers for decades.

Ensure Stable Access Points

The most dangerous moment on a job is often the transition from the ladder to the roof. You've got to make sure your access points are rock-solid and free of debris. Reinforce the 4-to-1 ratio rule with your crew and ensure every ladder is tied off at the top to prevent a kick-out during that critical step-off.

Foster a Safety-First Workplace Culture

Safety isn't a one-time meeting; it's a daily mindset of communication and teamwork. By conducting frequent training sessions and performing hands-on equipment inspections, you build a culture where workers feel empowered to speak up when they see a hazard. A proactive team is always more effective than a reactive one.

Encourage Regular Use of Trauma Straps

A successful fall arrest is only the first half of the battle. Suspension trauma can become life-threatening in minutes if a worker is hanging in a harness. Equip every member of your crew with trauma straps and make sure they know how to deploy them so they can "stand up" in their harness and maintain circulation while waiting for rescue.

Secure Work Areas with Protective Barriers

On low-slope IMETCO roofs, passive protection is often your best friend. Setting up guardrails or warning lines creates a physical and visual boundary that allows your crew to focus on their work without constantly looking over their shoulder at the leading edge.

Wear Appropriate Footwear

Metal roofs can become incredibly slick with just a few drops of water, morning condensation, sawdust, or pollen. Make sure your team is wearing footwear with soft, slip-resistant soles designed for traction on metal. If the metal panels are wet, it's best to avoid walking on them to prevent slips and falls.

Equip Workers with High-Quality Safety Gear

When it comes to harnesses and shock-absorbing lanyards, don't cut corners. High-quality gear isn't just safer; it's more comfortable, which means your crew is more likely to wear it correctly. Modern, lightweight equipment reduces fatigue and effectively manages impact forces in the event of a fall. In 2025, OSHA reinforced the importance of providing properly-fitting fall protection equipment to workers.
