The short answer
Restrict the failed anchor immediately. Then have a qualified person decide whether to repair or replace it, retest and recertify it, and update your records before any rope descent work uses it again.
Step 1: Restrict access right away
- Take the anchor out of service and mark it so no one ties off to it
- Update the roof plan and anchor register
- Tell every contractor who works on the roof
- Reschedule any rope descent work that depends on it
Step 2: Find the cause
- Corrosion at the base or fasteners
- Damage from roof work or rooftop equipment
- Movement in the substrate or structure below
- An anchor that has taken a fall or shock load
- An anchor that was never rated for the load
The cause decides whether a repair will hold.
Step 3: Repair or replace
| Situation | Usual path |
|---|---|
| Localized, repairable damage with sound structure below | Repair, then retest and recertify |
| Deterioration of the anchor itself | Replace with an engineered anchor, then certify |
| Anchor in the wrong place for the drops needed | Relocate or add anchors to the layout |
| Unknown or unrated anchor | Engineering evaluation and testing, or replacement |
Coordinate with your roofer on any work through the membrane so the roof stays watertight.
Step 4: Retest, recertify, document
The repaired or new anchor needs testing and certification by a qualified person before use, and the report and register need updating. See what the report should contain.
Keeping work moving meanwhile
- Rig affected drops from other certified anchors, where the layout allows
- Clean lower sections from the ground or a lift. See Mid-Rise (4-7 stories).
- Prioritize entrances and the most visible elevations
- Schedule the fix before peak season

Uncertified anchors expose the owner to serious OSHA liability and can halt all high-rise work. Through its long-time anchor partner, S&K installs engineered anchor points and inspects, load tests and certifies existing systems, with records you can hand to ownership, insurers or auditors. See anchor installation and inspection.
