The following photographs show  nuclear readings being taken on a Modified Bitumen Roof System and on a Ballasted Roof System.  Examples of the finished drawings for a nuclear moisture survey are also shown.

 

 

 

 

This is a nuclear moisture survey in progress on a modified bitumen roof system.  Nuclear readings are being taken at grid points that were laid out on the roof surface.  As the readings are taken, they are also recorded on the drawing.

 

 

 

 

 

 

 

 

This nuclear moisture survey is being conducted on a Ballasted Roofing System.  The ballast has been removed at the grid point locations so that the meter can be placed directly on the membrane.  On Ballasted Roof Systems nuclear moisture detection is the only viable system to use.  Infra red will not work on this type of system.
