OSHA 1910.27: Roof Anchor Requirements for Building Owners

OSHA 1910.27 establishes important safety requirements for rope descent systems used in general industry. For commercial building owners and property managers, one of the most important parts of this regulation involves rooftop anchorages.

When contractors use rope descent systems for window cleaning or building maintenance, they need suitable anchorages and the required written information before beginning work.

Under OSHA 1910.27(b)(1), building owners have specific responsibilities involving the identification, inspection, testing, certification, and maintenance of these anchorages.

What Does OSHA 1910.27 Require?

The standard establishes several requirements for rope descent systems and their anchorages.

For covered anchorages, the building owner must provide written information to the employer using the system stating that each anchorage has been identified, tested, certified, and maintained to support at least 5,000 pounds in any direction for each employee attached.

That information must be based on:

• Annual inspections by a qualified person.
• Certification by a qualified person as necessary and at least every 10 years.
• Proper identification, testing, and maintenance of each applicable anchorage.
• Written information provided before the contractor uses the anchorages.

The employer using the rope descent system also has responsibilities for worker training, equipment inspection, fall protection, and prompt rescue.

Does OSHA Require Roof Anchors to Be Load Tested Every 10 Years?

OSHA 1910.27 requires qualifying anchorages to be tested and certified, with certification performed as necessary and at least every 10 years.

However, the regulation does not establish one universal proof-load testing procedure that must be performed on every anchor every 10 years.

The appropriate evaluation depends on the anchorage design, available engineering documentation, manufacturer requirements, condition, and other applicable criteria.

Building owners should work with qualified professionals to determine the appropriate inspection, testing, and certification scope.

What Records Should Building Owners Maintain?

Property managers should keep available documents organized and accessible, including:

• Roof anchor drawings and identification records.
• Annual inspection reports.
• Anchorage certification documentation.
• Applicable load-testing reports.
• Engineering evaluations.
• Repair and replacement records.
• Written anchorage information provided to contractors.

Good documentation helps contractors understand whether the installed system is appropriate for the intended work.

What Happens if Roof Anchor Documentation Is Missing?

Missing documentation can delay window cleaning, façade maintenance, and other rope descent operations.

Contractors must obtain the required anchorage information before employees use those anchorages under OSHA 1910.27.

If records cannot be located, building owners may need an additional inspection, engineering evaluation, testing, or other corrective action.

Addressing these concerns before the next maintenance project can help reduce interruptions.
