Who Is Robertson Building Systems?
For over 150 years, Robertson Building Systems has been a pillar of the Canadian custom-engineered building industry. Founded in 1863, the company is now a primary brand within Cornerstone Building Brands, North America's largest supplier of residential and commercial building solutions. Strategically headquartered in Burlington, Ontario, and supported by a vast network of manufacturing facilities across Western Canada and the Maritimes, Robertson delivers innovative, high-quality building envelopes tailored to the unique demands of the Canadian market. Every profile is backed by deep local knowledge of regional snow loads and wind requirements, making them a trusted partner for builders from British Columbia to Newfoundland.
Why Specialized Fall Protection is Crucial for Robertson Roofs
Safety is paramount when working on high-performance standing seam panels. Because Robertson systems utilize concealed fasteners and floating designs to manage thermal expansion, traditional penetrating anchors are strictly prohibited. Drilling into these panels causes immediate leaks and voids the manufacturer's warranty. Contractors must utilize specialized, non-penetrating anchors that clamp to the standing seams to preserve structural integrity while providing a certified tie-off.
To ensure 100% tie-off without voiding manufacturer warranties, we recommend the modular SSRA system. The SSRA1 Seam Anchor serves as the foundation of this system, featuring a robust, one-piece body with no moving parts. Its patented, universal-fit design accommodates approximately 95 percent of today's standing seam profiles, eliminating the risk of incorrect assembly due to varying seam shapes and the financial burden of purchasing multiple anchor styles for different projects.
For Robertson standing seam projects, you have two primary fastening options:
- Cupped Tip Stainless Steel Set Screws: Use these for 22-gauge steel panels. The cupped tip creates a solid mechanical lock on the seam. You must torque these to 90 inch-pounds using a calibrated torque wrench.
- Nylon-Tipped Set Screws: Use these for 22- or 24-gauge steel panels where preserving the paint finish is the priority. You must torque these to 180-200 inch-pounds.
The SSRA1 serves as an adaptable mounting solution for several configurations:
- SSRA2 Adjustable Roof Jack Adapters: Mount directly to the SSRA1 to support 10-foot wooden walk-boards for stable footing on steep slopes.
- SSRA3 Anchor Plates: These plates connect two SSRA1 anchors into a single assembly, creating endpoints for horizontal lifelines.
- 100-foot SSRA Horizontal Lifeline Kit: Allows two workers to move the entire length of the roof without ever having to disconnect their lanyards.
- 120-foot Super Anchor Permanent HLL: A reliable, long-term solution using non-penetrating 5-inch riser posts that allow the floating roof to move naturally.
- The Ridge Pro Steep Assist: The essential First-Man-Up solution that secures to the roof peak before the worker leaves the ladder.

Mitigating Corporate Liability: The High Cost of Uncertified Fall Protection
A Robertson building represents a premium investment in engineering, and your fall protection must meet that same professional standard. Deploying unbranded or generic imported anchors is a direct threat to your firm’s financial and legal standing. Regulatory inspectors now actively target non-serialized hardware that lacks verifiable, third-party engineering data.
Failure to produce a certified test report confirming compliance with OSHA 1926.502 and ANSI standards during a site inspection can trigger immediate, severe penalties. Beyond Willful Violation fines exceeding $100,000, you face site-wide shutdowns and project delays. For a contractor, these disruptions lead to liquidated damages, lost bonding capacity, and irreparable damage to your safety rating. If an anchor lacks a documented third-party paper trail, it is a liability that has no place on a Robertson job site.

10 Essential Safety Guidelines for Robertson Building Systems Projects
- Enforce First-Man-Up Protocol: On pitches between 6/12 and 12/12, never step onto the roof without The Ridge Pro. This device ensures the worker is 100 percent tied off the moment they transition from the ladder to the peak.
- Verify Torque Settings Daily: Set-screw tension is not a set-and-forget task. Use a calibrated torque wrench every morning to ensure anchors remain at their required specifications.
- Eliminate Clip-Location Guesswork: Traditional anchors force contractors to search for hidden clips beneath the panel to ensure a secure hold. The SSRA1 eliminates this frustration by securing directly to the seam, providing a certified 5,000-pound tie-off point regardless of clip location.
- Stop No-Name Liability: Avoid unbranded, imported knock-off anchors. If an anchor lacks a verifiable 3rd-party test report for compliance with OSHA 1926.502, it poses a liability risk that could lead to a Willful Violation and $100,000 fines.
- Neutralize the Pendulum Effect: Always calculate your dynamic sag and fall distance. Keep the work zone within a 30-degree arc of the anchor point to prevent dangerous swing falls that could result in collisions with the ground or structure.
- Preserve Thermal Flexibility: Robertson panels float to manage Canada's extreme temperature swings. Only use non-penetrating clamps that allow for this natural thermal expansion, preventing the panels from buckling or oil-canning.
- Defend Against Galvanic Corrosion: Never mix incompatible metals. Use only Stainless Steel set screws on Robertson steel panels to prevent chemical reactions that lead to rust and structural failure.
- Mitigate Suspension Trauma: Equip every worker's harness with relief straps to prevent suspension trauma while waiting for rescue teams to arrive.
- Protect the Panel's Structural Integrity: High-torque, two-piece anchors can crush standing seams, damaging the roof and voiding warranties. Prioritize the SSRA1 low-torque design, which requires only 90 inch-pounds to achieve a full-strength lock.
- Consult Pros for Complex Roof Shapes: Custom Robertson projects often feature curved, serpentine, or convex rooflines. A qualified safety professional must perform a mandatory on-site inspection of these specialized profiles before deploying any fall protection.
