Precision Thermal Drone Surveys & Roof Inspections
We locate hidden roof leaks, heat loss, and structural defects across South East England, Kent, and London. No scaffolding. No ladders. 100% safe.
ALMA Digital Ltd delivers survey-grade structural inspections, advanced sub-surface thermal diagnostics, and ultra-high-definition video and images across South East England, London and Kent. We eliminate the need for high-risk and expensive scaffolding, cherry-pickers, and dangerous ladders and deliver centimetre-accurate intelligence from a completely non-intrusive, ground-isolated footprint. Our advanced radiometric thermal sensors see through building surfaces to pinpoint problems in minutes.
Our CAA Compliance
We operate fully within the UK Civil Aviation Authority (CAA) Open Category Framework (C2 Subcategory) and hold verified A2 Certificates of Competence (A2 CofC). Every site deployment is backed by a permanent £5,000,000 commercial public liability policy compliant with EC Regulation No. 785/2004.
Thermal Drone Surveys
Identify critical heat anomalies and energy loss with our state-of-the-art thermal drone surveys. We provide detailed reports for predictive maintenance and enhanced operational safety. Our thermal drone surveys help identify hidden defects that are often invisible during standard visual inspections. Using advanced thermal imaging technology, we can detect trapped moisture, water ingress, insulation failures, heat loss, and areas of potential deterioration across flat and pitched roofs.
By identifying issues at an early stage, property owners and facilities managers can plan targeted maintenance, reduce repair costs, and avoid unexpected failures that may disrupt operations or damage assets.
Residential Thermal Insulation & Leak Surveys
The building envelope plays a critical role in protecting a structure from weather, moisture, and energy loss. Our thermal drone inspections assess roofs, façades, cladding systems, and external building elements to identify defects that may compromise building performance.
Thermal imaging can reveal insulation deficiencies, thermal bridges, moisture intrusion, and areas of heat loss, helping clients improve energy efficiency, maintain compliance, and protect the long-term value of their property.
Comercial Asets Inspection & Development Surveys
Elevate your asset management from reactive to proactive. Whether you manage industrial warehouses, large-scale commercial developments, or corporate facilities, thermal drone surveys provide a non-destructive, high-resolution "health check" that manual inspections simply can’t match.
Traditional inspections are time-consuming and often miss what the naked eye cannot see. Our drone-based thermal imaging detects anomalies in real-time, offering critical advantages:
Identify structural heat loss, moisture ingress, or insulation gaps during and after construction to ensure peak energy performance and build quality.
Rapidly scan vast roof areas for leaks and structural compromises without the need for expensive scaffolding or downtime.
Protect your investment by identifying electrical hotspots in HV infrastructure or machinery before they lead to costly failures or fire hazards.

Residential Applications Covered
Thermal Imaging Inspections
Fast, non-invasive heat loss inspections pinpoint water ingress and thermal bridging in walls, windows, doors, and roofs, and identify air leakage and damp with high-resolution thermal imaging. Detailed assessment of external walls and high facades on large houses using a 4K camera.
Roof & Moisture Surveys
Detect hidden water leaks under roof membranes and flashing or pooling water that isn't visible to the naked eye, preventing major structural damage.
Solar Panel Health Checks
Inspect residential solar installations for hotspots or defective cells that can lower energy output and potentially pose fire risks. We can verify that your solar panels are installed correctly and free from any faults or defects, whether covered under warranty or caused by wear and tear over time.
Building Envelope & Energy Audit
Whether you’re purchasing an older home, investigating suspected damp, or assessing a property’s energy performance, Thermal Imaging offers clarity and confidence that a traditional visual inspection cannot match.
Industrial Applications Covered
Asset & Infrastructure Inspections
Regular thermal inspections help asset owners maximise system performance, reduce downtime, and support preventive maintenance strategies, ensuring optimal return on investment.
Solar Photovoltaic (PV) Inspection
String-level and cell-level failure tracking, identifying bypass diode failures, hot spots, internal resistance anomalies, and cracked sub-strings.
High-Voltage Electrical Infrastructure
Detection of localized resistance heating at junction points, terminations, transformers, and distribution components.
District Heating & Mechanical Assets
Identification of subsurface fluid distribution leaks, pipeline insulation degradation, and industrial HVAC fluid dynamics issues.
Agriculture & Environmental Applications Covered
Livestock Management
Monitor livestock health by detecting body temperature variations and track animals across large areas, even at night.
Wildlife Conservation
Conduct deer population counts or locate fawns hidden in long grass before mowing to prevent accidents.
Precision Farming
Inspect residential solar installations for "hotspots" or defective cells that reduce energy output and can pose fire risks.
Safety & Security
Conduct surveillance over large areas to detect unauthorized perimeter breaches using discreet aerial monitoring methods.
Public Safety & Emergency Applications Covered
Search and Rescue (SAR)
Use heat signatures to locate missing persons or pets in low-light conditions, dense forests, or rugged terrain.
Firefighting Support
Assist local crews by mapping heat sources and fire spread through smoke to help them target water drops more effectively.
District Heating & Mechanical Assets
Identification of subsurface fluid distribution leaks, pipeline insulation degradation, and industrial HVAC fluid dynamics issues.
