Moisture Scanning

We have a full range of trolley mounted and hand held capacitance meters designed specifically for detecting moisture within built up roofing systems which we offer as an alternative to our infrared thermal imaging surveys.

Roof Leak Detection

If you suspect your roof is retaining water our roof leak detection procedure will enable us to locate trapped moisture within your roofing system swiftly, accurately and without the need for destructive and penetrative measures.

We offer moisture scanning as an alternative to our infra-red roof inspections, as whilst thermal roof surveys are often useful there are some occasions where it simply isn’t the most suitable tool for the job.

Moisture Scanning is particularly useful for detecting moisture in roofing systems:

  • Above unheated buildings
  • Where there are heat generating sources at roof level
  • Where the roof waterproofing is covered with chippings or similar.

Access To The Latest Moisture Scanning Technology

At NWIR we’ll always offer you a range of solutions to every problem, along with expert advice about which you should choose and why. And if a moisture scanning survey seems appropriate we’ll employ the very latest in non-destructive scanning technology – the Dec Scanner.

This versatile and reliable device employs low-frequency electrodes to measure the moisture content of your roof with pinpoint accuracy, allowing us in turn to generate a moisture map and roof condition report informed by high-quality data samples. These surveys are simple and straightforward to conduct, requiring no downtime or disruption to your business.

After the Completion of your Moisture Scan Roof Survey

Upon completion the report we provide contains a complete photographic documentation of your roof’s current state, along with our recommended actions for repair included for your convenience. Moisture scanning technology is most appropriate for detecting problems above unheated buildings, where heat generating sources are present at roof level, and when your roof contains a layer of chippings or other loose materials.

But regardless of what method of covering you employ, and whatever condition your roof is currently in, our commercial roofing contractors will always tailor-make the most effective roof diagnostics solution for your situation.
