    <p><font size="4">There are very good roof mounting systems that do
        not require finding the rafter. There was a thread on this
        within the past two weeks.  I understand the comfort of lagging
        into a rafter, but unless you can see the rafters from below,
        you'll never know 100% you did not come out the side of the
        rafter, especially if the rafter is checked. We use the hammer,
        two pilot holes to establish the rafter edge if we are attaching
        to the rafter. That is a cool tool though that I never saw
        before.  Chris</font><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>
