Thermal Imaging Surveys
Thermal Image Capture
Precision drone thermal surveys that reveal heat loss, damp and hidden faults across roofs and building envelopes, captured safely from the air, with no scaffolding and no disruption.
EXPLAINER
DRONE THERMAL IMAGING SURVEYS, EXPLAINED
A drone thermal imaging survey uses a radiometric infrared camera mounted on a UAV to measure the surface temperature of a building from the air. Because heat behaves differently where insulation is missing, moisture is present or air is escaping, these temperature patterns reveal problems that are invisible to the naked eye — across entire roofs and facades, and without scaffolding or disruption.
It is a fast, non-invasive way for property owners, managing agents, surveyors and insurers to pinpoint heat loss, damp and hidden defects before they become costly. Every survey is flown by a qualified drone pilot and interpreted by an experienced operator, so the findings you receive are ones you can act on.

WHERE THERMAL IMAGING MAKES THE DIFFERENCE
Heat loss & insulation gaps
Spot missing or degraded insulation and thermal bridging across roofs and walls, so energy stays where it belongs.
Damp & water ingress
Identify moisture, tracking water and trapped damp by the tell-tale temperature signatures they leave behind.
Flat roof leak detection
Locate the source of flat-roof leaks by mapping where wet insulation retains heat, so repairs can be targeted precisely.
Solar & electrical faults
Reveal hot spots on solar arrays, connections and electrical plant that signal faults long before they escalate.
Non-invasive inspection
Survey the whole building envelope from the air with no scaffolding, no access equipment and no disruption to occupants.
Fast, complete coverage
Capture an entire roof or elevation in a single flight, giving comprehensive data in a fraction of the time.

HOW A THERMAL DRONE SURVEY WORKS
-
01
Survey planning
We assess the site, agree objectives and plan the flight and airspace so the survey is safe, compliant and focused on what matters to you.
-
02
Optimal-condition flight
We fly when thermal contrast is greatest, capturing the roof and envelope with a calibrated radiometric camera.
-
03
Radiometric capture
Every image records true temperature data, not just a colour picture, so anomalies can be measured and compared.
-
04
Expert analysis
An experienced operator interprets the imagery, separating genuine defects from harmless temperature variation.
-
05
Actionable report
You receive a clear report with annotated thermal and visual images, as well as our findings and recommended next steps.
IN_THE_FIELD
THERMAL IMAGING IN ACTION
Thermal imagery turns invisible temperature differences into a clear visual map, making heat loss, damp and defects immediately obvious and easy to communicate to clients, insurers and maintenance teams.
LAUNCH_FAQ
THERMAL IMAGING SURVEY FAQs
How accurate are drone thermal surveys?
Radiometric cameras measure surface temperature to within a fraction of a degree. Combined with the right survey conditions, this reliably highlights anomalies such as missing insulation, damp and air leakage for closer investigation.
When is the best time to carry out a thermal survey?
When thermal contrast is greatest typically cool, dry, overcast conditions, often early morning or after sunset, with a temperature difference between inside and outside. We advise on timing when you book.
Can you detect damp or a roof leak from the air?
Yes. Moisture changes how a surface holds and releases heat, so wet areas and tracking water often show as clear thermal patterns across roofs, parapets and facades.
Do I need scaffolding or roof access?
No. The drone captures the whole roof and envelope from the air, so there is no scaffolding, no access equipment and no working at height. This is what makes a drone survey faster, safer and lower cost.
What deliverables do I receive?
A report with annotated thermal and visual images pinpointing anomalies, plus our findings and recommended next steps. Formats can be tailored for insurers, surveyors or maintenance teams.
Which areas do you cover?
We carry out thermal drone surveys across London and UK-wide. Get in touch with your location and we will confirm availability.
