Removing an old roof-mounted accessory leaves attachment points that need a compatible repair. Cutting off the visible bracket does not restore the underlying roof layers. The condition around the mount may also need evaluation.
What to do next
Ask who will remove the equipment and who will restore the roofing. Request a scope covering the penetrations and affected covering. Keep completion photographs so a future leak investigation can identify where the former attachment was located.
