    <p>If the temperature is right, my IR camera can see the rafters. 
      Best to check early on a cold morning with the heat on in the
      building.  Otherwise I'm of the William "Hammer" system
      persuasion.  Never found anything better.<br>

        <div>I started using the Bosch D-tect 150 a few years ago after
          a friend who had success with it recommended it.  Works great
          on most roofs.  It needs a smooth surface to roll on so I use
          a piece of Soladeck box.  Older roofs with ply over roof
          boards don't scan very well so I sometimes go back to the
          mallet method.  </div>
        <div><br>
        </div>
        <div>I also highly recommend the Chip Tool!  Every installer
          should have one.  It's best use in my opinion is for
          installing fall protection.  I don't recommend it be used with
          a "micro flashing" though, as the pilot hole next to the
          rafter may only be barely covered by the "flashing".</div>
