Flag Display Guide. Displaying the Flag at Half Mast: When you need to display the American flag at half mast, you actually need to hoist it completely to the peak of the pole and then instantly lower it to the half staff position. At the close of the day, the flag should again be raised to the peak of the flag pole and then lowered completely.
When the American flag is flown at half-staff, state and other flags should be removed or flown at half-staff too. If Your Flag Can't Fly at Half-Staff For flags that can't be lowered, such as those on many homes, the American Legion says that attaching a black ribbon or streamer to the top of the flag is an acceptable alternative.
