Visual Inspection vs. Load Test: What's the Difference?
visibility Two different jobs, often confused
Building owners frequently assume a roof anchor inspection is one thing. It is really two very different procedures, done by different people, with different outputs. A visual inspection is a hands-on look at the anchor and its structure - no force is applied. A load test physically pulls on the anchor to a proof load and confirms it holds. One tells you whether an anchor looks sound; the other proves it is sound to a defined safety factor. Knowing which one your building actually needs - and when - is the difference between a compliant program and a false sense of security. See our roof anchor certification overview for how the two fit together.
search The annual visual inspection
Under OSHA 1910.27(b), rope-descent-system anchorages must be inspected annually by a qualified person. A parallel requirement in OSHA 1910.140 puts a competent-person check on personal fall-arrest anchors before each use, and ANSI/IWCA I-14.1 supplies the detailed inspection procedure for window-cleaning and suspended-access systems.
A proper annual visual covers the things that fail in the field: tamper pins present and seated, thread deformation or stripping on the stud, condition of the back plates, rust and corrosion (a fast-mover in South Florida salt air), the parapet type and how the anchor is attached to it, and whether the installation still matches the engineered drawings on file. Everything is photo-documented. Critically, a visual inspection applies no force and requires no PE stamp - a qualified person can perform and sign it.
science The PE-directed load test
A load test is a physical proof load - the anchor is actually pulled to a target force under the direction of a licensed professional engineer. This is what certifies an anchor for suspended access and, per ASME A120.1, is required for powered platforms, suspended scaffolding, and davit systems.
The load figures come from the governing standard. Under ANSI/IWCA I-14.1, a tieback anchor is proof-loaded to 2,500 lbs static - a 2x safety factor over the 1,250 lb allowable service load. Under ASME A120.1, davit posts and arms are tested to 2x the working load. The pass/fail line is exact: permanent deflection greater than 1/16 inch under load is a failure, and the anchor is tagged out of service until it is repaired or replaced. A load test produces a PE-sealed certificate per anchor - the document a window-washing or facade contractor needs before they will rig to your roof.
balance When each one is required
The trigger is the type of work and the certification clock. Annual visual inspection by a qualified person is the ongoing baseline for any RDS anchorage under 1910.27. Load testing under PE direction is what backs the certification at least every 10 years (sooner if a problem is found) that OSHA requires for RDS anchorages, and it is mandatory whenever anchors support suspended access - rope descent, powered platforms, or davits under ASME A120.1.
In practice: an annual visual keeps you inside the yearly requirement and catches deterioration early, while the periodic PE load test and sealed certificate are what let a suspended-access crew legally hang from the anchor. The owner must keep the certification on file and hand it to contractors before work begins. For the timing details, see our rope-descent recertification guide and the compliance calendar.
description What each one produces
A visual inspection produces a dated, photo-documented report signed by a qualified person: anchor-by-anchor condition, any deficiencies flagged, and confirmation that the installation still matches the engineered drawings. It carries no engineer's seal because none is required. A load test produces a PE-sealed certificate for each anchor that recorded the proof load applied and confirmed the anchor passed - the legally weighty document that unlocks suspended-access work and satisfies the 10-year certification requirement.
Treating these as interchangeable is where owners get exposed. A stack of visual reports does not satisfy a load-test certification requirement, and a 10-year certificate does not excuse you from the annual visual in between. Missing either can turn into an OSHA citation - up to $16,550 for a serious violation and up to $165,514 for willful or repeat violations under the 2026 penalty schedule.
engineering How La Gala handles both
La Gala Construction (dba Tilt Patchers, Inc.), a Florida State Certified General Contractor (CGC 059211), coordinates the full sequence under one contract. Our independent, licensed Florida PE partner performs and seals the engineering work - the proof-load testing and the per-anchor certificates - while La Gala self-performs the corrective and repair work when an anchor fails the 1/16-inch deflection threshold or turns up deficient on the annual visual. To be precise: La Gala does not provide engineering services itself; the seal is the PE's. You get the annual visual, the periodic PE-sealed load-test certification, and the fix for anything that fails - documented and ready to hand to your suspended-access contractors. Start with a comprehensive assessment or browse the full library of compliance guides.
Not sure whether you need a visual, a load test, or both?
Our PE partner certifies it and our crews fix it, under one contract. Start with a comprehensive, no-obligation assessment of your roof anchors, or build a custom compliance plan in two minutes - so you know exactly which inspection and which certificate your building owes, and when.
