Who Is McElroy Metal?

McElroy Metal continues to lead the American metal roofing industry with a legacy built on craftsmanship, innovation, and family values. Founded in 1963 by Thomas E. McElroy, Sr. in Bossier City, Louisiana, McElroy Metal began as a small regional manufacturer producing high-quality roofing and siding components. Over time, it evolved into a national leader known for precision engineering and exceptional service. Under the guidance of the McElroy family, the company expanded to 13 manufacturing facilities, 27 service centers, and 45 retail locations across the United States.

In 2011, McElroy entered the insulated metal panel market, solidifying its reputation for combining tradition with modern building science. Today, McElroy Metal operates as an employee-owned business. From commercial developments and architectural projects to residential systems, McElroy products continue to set the standard for performance and durability in the metal roofing industry.

Why Are Non-Penetrating Fall Protection Anchors Required For McElroy Standing Seam Roofs?

Standing-seam metal roofs from McElroy Metal require fall protection systems that protect both the worker and the roof. McElroy's standing seam panels must remain free of penetrations to preserve performance and warranty coverage. Standard screw-down anchors are incompatible with these systems because they pierce the panels, break the watertight seal, and risk corrosion over time.

Non-penetrating clamp-style anchors grip securely to the seams without drilling, keeping the roof fully intact. These solutions provide OSHA- and ANSI-compliant tie-off points that maintain McElroy's structural integrity and finish. Whether you are installing McElroy's Maxima, Medallion-Lok, or 138T and 238T Standing Seam Roof Systems, non-penetrating anchors deliver unmatched safety, preserve warranties, and ensure long-term performance on every job.


Fall Protection Systems for McElroy Metal Panels

To maintain the integrity of these high-performance systems, specialized fall protection is required. The following products provide the primary safety solutions for McElroy installations:

  • SSRA1 Standing Seam Roof Anchor: The foundation of the system. This anchor provides a non-penetrating, certified 5,000-pound tie-off point using 12 cupped-tip or nylon-tipped set screws.
  • SSRA2 Adjustable Roof Jack Adapters: Mount directly to the SSRA1 anchors to create level work platforms on steep slopes using 10-foot wooden walkboards.
  • SSRA3 Anchor Plates: Heavy-duty aluminum plates that secure across two SSRA1 anchors to serve as certified endpoints for horizontal lifelines.
  • SSRA HLL 100-foot Temporary HLL Kit: A complete turnkey system providing continuous tie-off for up to two workers in fall arrest, allowing safe lateral movement across wide spans.
  • 120-foot Super Anchor Permanent HLL Kit: An industry-exclusive galvanized-steel-cable solution for roofs requiring regular maintenance without penetrations.
  • Ridge Pro Steep Assist: A peak-mounted system for slopes between 6:12 and 12:12, providing 100% tie-off from the ladder to the ridge.

Proper Attachment: Set-Screws and Torque Requirements

Worker safety and the holding power of the SSRA1 anchor depend entirely on correct set-screw application:

  • Cupped-Tip Stainless Steel Set-Screws: Use these screws exclusively on 22-gauge steel panels. Torque these screws to 90 inch-pounds.
  • Nylon-Tipped Set-Screws: Apply these tips to 22- or 24-gauge steel panels to achieve certified holding power without marking the finish. Torque these screws to 180-200 inch-pounds.

Maintenance: Treat nylon tips as consumables. Replace these tips every 3 to 5 uses to maintain maximum grip strength.

CRITICAL WARNING: NO IMPACT GUNS

Never use an impact gun to install set-screws. Over-torquing with an impact driver crushes the standing-seam rib. This installation error damages the anchor hardware and voids the manufacturer's warranty. Always use a calibrated torque wrench for final installation.

Safety Tips For Standing Seam Roofs

Promote a Culture of Safety
Proper safety grows through teamwork and daily awareness. Short morning meetings build trust and accountability. Over time, safety becomes more than a checklist; it becomes part of the company's culture.

Use Specialized Anchor Systems for Standing Seam Roofs
McElroy Metal roofs require non-penetrating anchors that protect the roof and the worker. Clamp-style anchors create strong OSHA-compliant tie-off points without drilling into the panels. Avoid anchors that rely on locating hidden clips under existing panels.

Develop OSHA Compliant Safety Plans
Every project begins with a written safety plan outlining tie-off locations and rescue procedures. When everyone understands the plan, the crew works more efficiently and responds faster in emergencies.

Equip Workers with High Quality Safety Gear
A safety system is only as reliable as the gear that supports it. OSHA standards emphasize correct sizing for all equipment. When gear fits comfortably, workers stay confident and focused.

Set Up Protective Guardrail Barriers for Work Zones
Guardrails protect workers before they ever clip in. Well-placed guardrails define safe work zones near edges and skylights, allowing crews to concentrate on their tasks without constantly worrying about footing.

Ensure Proper Footwear for Stability
Safe footing begins with proper boots. Shoes with slip-resistant soles and firm ankle support prevent fatigue and improve traction on smooth metal panels.

Prioritize Ladder Safety Training
Most job site injuries occur before anyone reaches the roof. Inspect ladders before use, set them at the proper four-to-one angle, and always maintain three points of contact.

Encourage the Use of Trauma Straps
Fall arrest doesn't end when the fall stops. Trauma straps allow a suspended worker to stand in their harness and maintain circulation until rescue arrives. Every harness should include them.

Install Permanent Roof Anchor Systems
Permanent anchors provide long-term safety for roofs that need regular maintenance. They remove setup delays and ensure every trip to the roof begins with confidence.

Consult Experts for Curved Metal Panels
Curved roofs require specialized safety strategies. The unique shape affects how anchors perform. Have a fall protection expert inspect the structure before starting work.
