I work at a small town fire department where we obviously display a flag. We recently had a remodel and our flag pole is now a couple feet away from the building. When the flag is flown at half mast the flag rests on the roof of the building. I have been flying it just high enough that it does not touch the roof, but that is not a true half mast. Is this okay, or should it be at half mast? I am sure the obvious answer here is to move the flag pole, but that is not an option.
