Final answer:
Upon discovering roof damage, a technician should promptly notify the building owner to allow them to make a decision regarding repairs. Directly repairing or ignoring the damage, or waiting without reporting can be unprofessional or lead to liabilities.
Step-by-step explanation:
When a technician finds damage on a roof, the best practice is to notify the building owner immediately. It is important for the homeowner or the person in charge of the building maintenance to be aware of the issue so that they have the opportunity to decide on the next steps. Repairing the roof without permission could lead to liability issues, ignoring the damage could worsen the problem and is unprofessional, and waiting for further instructions without notification may delay necessary repairs. Therefore, a technician's duty is to document the damage and ensure that the building owner is informed as soon as possible.
