Roof Access Ladders
Fixed Roof Access Ladder
Roof access ladders built to the rule as it reads today, including the ladder safety system requirement over 24 feet.
Roof Crossover Ladders
Steps up, a level landing, and steps down — safe passage over a parapet, duct run, or elevation change.
The Fixed Ladder Cage Rule Change
This one catches facilities off guard, so it is worth stating plainly. OSHA concluded that cages and wells do not reliably stop a fall — a falling worker can drop the full height inside a cage. The rule was rewritten around active protection instead.
- Fixed ladders over 24 feet must have a ladder safety system or a personal fall arrest system.
- New ladders installed after the rule took effect must comply immediately; a cage does not satisfy it.
- Existing caged ladders must be retrofitted by the phase-out deadline.
- Any replacement of a ladder or ladder section triggers full compliance for that ladder.
If you are not sure where your ladders stand, an inspection documents every one and tells you which need retrofitting and in what order.
Roof Access Ladder FAQ
Answers on fixed ladder requirements, the cage rule change, and safe rooftop access.
A cage can remain on a ladder, but it no longer counts as fall protection on its own. Under 1910.28(b)(9), fixed ladders extending more than 24 feet require a ladder safety system or personal fall arrest system, and new installations cannot rely on a cage to satisfy that. Existing caged ladders must be retrofitted by the phase-out deadline.
A vertical cable or rigid rail running the length of the ladder, with a sleeve or trolley that the climber attaches to their harness. The device travels freely while climbing and locks the moment it senses a fall, arresting the worker within inches instead of letting them drop the full height. It can be added to most existing ladders as a retrofit.
That transition is the highest-risk moment of the climb, and it is frequently overlooked. Side rails must extend at least 42 inches above the landing so the climber has something to hold while stepping off. Beyond that, the landing area itself often needs a self-closing gate and guardrail, since the worker is arriving at an unprotected roof surface. We supply the ladder, the extension, and the landing protection as one package.
A stepped structure that takes a worker up one side of an obstacle and down the other — over a parapet wall, a change in roof elevation, a duct run, or a pipe rack. It replaces the alternative, which is people climbing over the obstruction and jumping down. Crossover ladders include handrails and a level landing platform at the top.
In most cases, yes, and retrofitting usually costs far less than replacement. We inspect the existing ladder for structural condition, rung spacing, and side rail extension, then add a ladder safety system, extend the rails, or correct the landing as needed. Where a ladder is too far out of specification or corroded, we will say so and quote a replacement instead.
