Do Roof Anchors Need to Be Re-Certified After a Roof Replacement or Major Roof Repair?
A commercial reroofing project can change much more than the waterproofing membrane.
It may change:
- Insulation thickness
- Flashing
- Roof elevations
- Drainage
- Equipment curbs
- Walk paths
- Penetrations
- Access routes
And sitting in the middle of that work may be one of the building’s most important safety systems:
the roof anchors.
Facility managers should therefore include fall-protection systems in reroofing planning rather than waiting until the new roof is complete.
Why Reroofing Can Affect Existing Anchors
A roof anchor typically interacts with both the building structure and the roofing assembly.
Roofing work around the anchor may involve removing and replacing materials surrounding penetrations.
That creates opportunities for:
- Components to be disturbed
- Flashing details to change
- Anchors to become buried
- Labels to disappear
- Corrosion to become visible
- Roof height relative to the anchor to change
- New materials to interfere with access
- Contractors to modify components unintentionally
The anchor may not have been intentionally altered, but the environment around it has changed.
Inspect Anchors Before Reroofing
The best time to discover an anchor problem is before the roofing contractor mobilizes.
A preconstruction assessment can document:
- Existing anchor locations
- Current condition
- Known deficiencies
- System documentation
- Anchors requiring special treatment
- Areas where new fall protection may be needed
This information can then become part of the roofing project’s planning.
Coordinate With the Roofing Contractor
Roofers should know which components are part of the building’s fall-protection system.
Roof anchors should not simply be:
- Cut off
- Covered
- Removed
- Modified
- Reflashed without coordination
Changes involving structural anchorage should be evaluated appropriately.
Coordination between the building owner, roofing contractor, fall-protection specialist and engineer can prevent expensive corrective work later.
After the Roof Is Finished
Once reroofing is complete, the fall-protection system should be evaluated based on what work occurred.
Questions include:
- Were anchors disturbed?
- Were any removed?
- Were components replaced?
- Did roof elevations change?
- Were anchors reflashed?
- Is identification still visible?
- Are access routes different?
- Was new mechanical equipment added?
- Does the existing anchor layout still work?
The answer determines what inspection, documentation, engineering or certification steps are appropriate.
Reroofing Is Also an Opportunity
A roof replacement is one of the best times to improve an inadequate fall-protection system.
If the existing building has poor coverage, a reroofing project may provide an opportunity to incorporate:
- Additional roof anchors
- Horizontal lifelines
- Guardrail systems
- Safe access paths
- Ladder systems
- Davit systems
- Purpose-designed rope-access anchors
Planning those improvements before the roof is finished is generally easier than returning later and disturbing a new roof.
Frequently Asked Questions:
Does replacing a roof automatically invalidate every roof anchor?
Not necessarily. The effect depends on what was changed and whether the anchors or supporting conditions were affected.
Can a roofing contractor remove an anchor?
Fall-protection components should not be removed or modified without understanding their purpose and coordinating the appropriate evaluation.
What if the roofing project already happened?
The existing anchors and available project documentation can still be evaluated to determine the next appropriate step.
Should anchors be inspected before or after reroofing?
Ideally both stages are considered: documenting existing conditions before work and evaluating the resulting system afterward.
Can new anchors be installed during reroofing?
Yes, and reroofing can be an efficient opportunity to integrate new engineered fall-protection systems when properly planned.
Planning a commercial reroofing project?
Bring the fall-protection system into the project before construction begins. Shine On Anchors can evaluate existing anchors and coordinate solutions for the new roof assembly.
