In which scenario must an inspector notify the client about the use of a drone?

An inspector must notify the client before flying the drone for a roof inspection because this action directly impacts how the inspection will be conducted and it informs the client about the methods being used. Using a drone for inspections can raise various concerns, including privacy, safety, and potential liability, which makes it essential for the inspector to communicate transparently with the client about the techniques and equipment being employed. This notification ensures the client is aware of the process and can express any concerns regarding the use of a drone.

In contrast, using a drone solely for aerial photography may not necessarily require prior notification, as it does not directly affect the inspection of the roof itself. Also, if the roof is in good condition, prior notice about drone usage may not be deemed necessary because the inspection would not uncover any significant issues. Finally, informing the client only when the drone captures malfunctioning components does not address the need for transparency regarding the methods being used, which is crucial regardless of the outcome of the inspection. Hence, proper communication of the drone's usage before conducting the inspection is vital for maintaining professional standards and client trust.
