Our Investigation Methods

Visual Inspection

Systematic visual assessment of all potential leak entry points including flashings, valleys, tiles and penetrations.

Thermal Imaging

Thermal cameras detect temperature differentials caused by moisture, locating hidden damp and leak tracks invisible to the naked eye.

Moisture Mapping

Electronic moisture meters map moisture distribution across roof and ceiling areas, tracing the water's path from entry to appearance.

Invasive Investigation

Where necessary, targeted access to roof space or structure to trace leak paths and identify the precise entry point.

Leak Investigation FAQs

Why can't my roofer find where my leak is coming from?

Roof leaks are notoriously difficult to trace because water travels along roof timbers, membranes and cavity walls before appearing at a visible point. The visible damp patch is rarely directly below the entry point. Our specialist leak investigation using thermal imaging and moisture mapping can locate the exact source when visual inspection alone has failed.

What is thermal imaging and how does it help find roof leaks?

Thermal imaging cameras detect differences in surface temperature. Wet materials have a different thermal signature to dry materials, allowing us to map moisture distribution across roof surfaces and ceiling areas. This reveals the leak track from entry point to visible damp, even through insulation and building materials.

How much does a roof leak investigation cost in Colchester?

Roof leak investigations in Colchester start from £149 for a standard visual investigation. Thermal imaging investigations from £199. Price varies depending on property size, access complexity and equipment required. All investigations include a written report identifying the source and recommended repair.

Will you repair the leak as well?

No. We investigate and report only — we do not carry out repairs. This means our leak investigation report is truly independent. We identify the exact source and recommend the appropriate repair, which you can then commission from any roofing contractor of your choice.
