Moisture Mapping

See What Is Happening Beneath The Surface.

Moisture mapping helps clients understand whether water is trapped within a roof build-up before committing to repair, overlay or replacement works.

Using specialist non-destructive equipment, we survey the roof in a systematic pattern to locate areas of elevated moisture that may not be visible from the surface.

Where required, targeted core samples can be taken to confirm the roof build-up, verify moisture levels and help interpret the significance of the readings.

The result is not just a moisture map, but a technical basis for deciding whether a roof can be overlaid, repaired locally or requires more extensive strip-up and replacement.

This helps clients avoid unnecessary replacement where moisture is isolated, and avoid inappropriate overlay where trapped moisture presents a wider risk.

Reporting

IntegriTest field technicians will scan your roof and provide you with a detailed report that includes a gridded map of the moisture levels and recommendations for any necessary repairs.

What we do in detail

Measuring moisture conditions in flat roofs

The Tramex dec-scanner is a non-destructive moisture meter that can determine the relative moisture levels in a build-up of up to 6 inches (152mm). IntegriTest will attend the site to carry out the moisture map using the dec-scanner and associated moisture meters and take pin measurements at the wettest and driest locations identified by the dec-scanner. Our trusted partners can provide dewatering and roof drying if required.

What roof type does moisture mapping work with?

IntegriTest can carry out moisture mapping on most flat roof constructions including but not limited to:

  • Warm roof construction with any deck type. 
  • Single-ply membrane, 
  • Built-up felt, 
  • Mastic Asphalt 
  • Hot-Melt 
  • Liquid Applied Membranes 
  • Cold roof
