The short answer
A drone pre-survey is a fast way to map anchor locations and document visible roof and anchor condition, especially on large or hard-to-reach roofs. It does not replace the hands-on inspection and testing a qualified person needs to certify anchors.
What a drone can do
- Map anchor locations against the roof plan
- Photograph visible corrosion, damage and membrane problems around anchors
- Document condition over time, with dated imagery
- Survey many roofs quickly across a portfolio
- Reduce roof trips on buildings with difficult access
What a drone cannot do
- Test an anchor or confirm its capacity
- Check fasteners, torque or hidden deterioration
- Certify anything: certification requires a qualified person and scientifically valid testing
When a drone pre-survey makes sense
- Before the annual inspection, to plan the inspector's time
- Before an acquisition or refinancing. See anchor compliance in due diligence.
- After a major storm, to spot damage before anyone goes on the roof
- Across a portfolio, to find the buildings that need attention first
Rules and courtesy
- Commercial drone flights in the US require a remote pilot certificate under FAA Part 107
- Airspace near airports and some urban areas may need authorization
- Tell tenants and neighbors before a flight over occupied buildings
Then get on the roof
Whatever the drone finds, the next step is a qualified person on the roof. 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.
