Flat Roof Moisture Surveys

Flat roof moisture surveys are used to identify areas of retained moisture within roof build-ups without the need for intrusive investigation.

At Southern Roof Diagnostics, we use specialist moisture mapping equipment to assess the condition of flat roofs, helping to determine the extent and spread of moisture within insulation and underlying layers.

This approach allows for informed decisions to be made regarding repairs or replacement, ensuring works are targeted and cost-effective.

When are Moisture Surveys Used?

Moisture surveys are typically used to assess the condition of flat roofs where water ingress is suspected or known to have occurred.

They are particularly useful in the following situations:

  • Investigating ongoing roof leaks or damp issues

  • Assessing the extent of moisture within existing roof systems

  • Determining whether a roof requires repair or full replacement

  • Verifying areas of concern prior to undertaking remedial works

  • Supporting condition surveys and lifecycle planning

By accurately identifying areas of retained moisture, this method helps avoid unnecessary replacement and ensures that any required works are properly targeted.

How Do Moisture Surveys Work?

Moisture surveys are carried out using non-destructive testing equipment designed to detect variations in moisture levels within roof build-ups.

Using specialist capacitance-based meters, we scan the roof surface to identify areas of elevated moisture beneath the waterproofing layer. These readings allow us to map the extent and distribution of moisture without the need for intrusive investigation.

Areas of concern are recorded and, where required, can be verified through further inspection methods to ensure accurate interpretation of results.

This approach provides a clear understanding of roof condition, supporting informed decisions on repair or replacement.

What You Will Receive

Following the survey, a clear and concise report is provided outlining all findings.

This includes:

  • Marked roof plans showing areas of elevated moisture

  • Photographic records of the roof condition

  • Summary of findings and observations

  • Guidance on targeted remedial works or further investigation where required

The survey results provide a clear understanding of the condition of the roof, helping to inform whether localised repairs or more extensive works may be necessary.

Ideal for contractors, surveyors and building owners looking to accurately assess roof condition without unnecessary disruption.
