Discover What Lies Beneath

What you can't see beneath a roof's surface can cause the greatest damage. Nimbus Roof Technologies specialises in advanced below-the-roofline diagnostics, combining thermal imaging, moisture detection, and core sampling to reveal hidden defects, assess performance, and plan repairs before issues escalate. Our approach gives you confidence in the integrity, longevity, and compliance of your flat roof assets.

Whether for maintenance, ecological benefit, or energy generation, Nimbus ensures every roof is used to its full potential while safeguarding people, buildings, and the environment.

Thermal Surveys - Seeing the Invisible

Thermal imaging allows us to detect moisture ingress, trapped water, and heat loss without destructive inspection. By pinpointing:

  • Areas of wet insulation
  • Localised leaks beneath membranes
  • Variations in thermal performance

…we can produce highly accurate, actionable data that guides refurbishment or maintenance decisions.

Core Sampling - The Physical Confirmation

While thermal surveys identify potential problem areas, core samples provide a physical assessment of the roof structure. By taking measured samples of membranes and insulation, we confirm:

  • Material composition
  • Condition of underlying layers
  • Extent and severity of moisture penetration

Combined with thermal surveys, core sampling ensures a comprehensive understanding of the roof's condition, forming the basis for informed decision-making.

The Nimbus Advantage - Diagnostics in Collaboration

Our unique USP lies in the integration of thermal imaging and core sampling. By using both together, Nimbus provides a complete picture of hidden roof issues: where moisture is located, how far it has spread, and the impact on thermal performance.

This collaborative diagnostic approach enables:

  • Targeted refurbishment strategies
  • Accurate risk assessment
  • Efficient allocation of resources
  • Long-term performance assurance

Detailed Reporting & Compliance

Every survey is accompanied by a comprehensive report, detailing:

  • Condition of the roof asset
  • Areas of concern and their severity
  • Expected lifespan of the existing system
  • Recommended remedial or refurbishment action
  • Compliance with industry standards and best practice

This evidence-based reporting ensures full transparency, supporting decision-making for architects, building managers, and facility teams.
