Thermal imaging used to be the kind of tech you’d only see in military documentaries or science fiction films. But today, it’s one of the most powerful tools in modern property maintenance, energy auditing, and industrial inspection. At Balmore Group, we’ve been at the forefront of using thermal drones to carry out precision surveys for clients across Glasgow and Scotland.
In this guide, we’ll walk you through the essentials, from how thermal imaging works to why drones have changed the game, what the surveys cost, and where you’ll benefit the most. Whether you’re managing commercial facilities, maintaining your home, or overseeing a large-scale infrastructure project, thermal drone surveys could be exactly what you need.
What Is Thermal Imaging?
Thermal imaging (or thermography) detects variations in heat using infrared cameras. Every object emits infrared radiation, and thermal cameras capture this to produce a visual “heat map” showing temperature differences.
This is particularly useful for spotting issues that the naked eye can’t detect, such as:
- Hidden leaks
- Heat loss through poorly insulated roofs and walls
- Electrical hotspots (overloaded circuits, overheating components)
- Water ingress in flat roofs
- Faulty solar panels
It’s non-contact, fast, and completely non-destructive, making it perfect for delicate or hard-to-reach areas.
Where Are Thermal Imaging Surveys Used?
Thermal surveys are incredibly versatile. At Balmore Group, we’ve delivered thermal inspections across a wide range of industries and environments, including:
- Residential Roofing: Our roof drone inspection service uses thermal imaging to detect leaks, heat loss and trapped moisture, especially useful for flat or inaccessible roofs. Many of our clients in the Glasgow West End and East End use these surveys as part of their regular property maintenance.
- Commercial and Industrial Sites: For larger buildings and facilities, industrial drone inspections allow us to detect insulation failures, HVAC issues, and energy inefficiencies that lead to skyrocketing utility bills.
- Solar Panel Farms: We utilise thermal drones to identify “hot spots” on panels, which indicate underperforming or faulty photovoltaic cells.
- Heritage and Historic Buildings: When working on older properties, thermal imaging is an ideal non-invasive method for detecting dampness, poor insulation, or internal leaks, without damaging the structure.
- Mechanical and Electrical Systems: Using thermal drones to fly over or around industrial systems is faster and safer than manual inspections, especially in confined spaces or areas with high-voltage equipment.
What Are the Benefits of Thermographic Surveys?
The advantages of a thermal survey go beyond basic inspections. Here are some key benefits:
- Early Detection Saves Money: Catching issues before they worsen helps avoid costly emergency repairs and extends the life of your roof or equipment.
- Improved Energy Efficiency: Identifying heat loss or insulation gaps can reduce your heating bills and carbon footprint.
- Fewer Health Risks: Detect damp and mould-related moisture build-up before it affects air quality or your building’s structure.
- Minimal Disruption: With drone-based surveys, we don’t need scaffolding or ladders, making the whole process much faster and safer.
- Accurate Reports: We provide clear, image-supported reports with thermal overlays and repair recommendations. Perfect for insurers, landlords or facilities managers.
Why Choose a Thermal Drone Over a Handheld Thermal Camera?
Traditional handheld thermal cameras are great, but they have limitations, especially for larger or elevated areas.
Here’s why thermal drone surveys offer the upper hand:
- Access: Reach high rooftops, chimneys, solar arrays, and confined spaces with ease
- Speed: Cover large areas in a single flight
- Safety: No need to send workers up scaffolds or into hazardous zones
- Better Data: High-res imaging combined with geo-referenced data
- Greater Detail: We can run thermal and visual imagery side-by-side for pinpoint accuracy
This is particularly useful for roofing contractors in Glasgow, surveyors, or property managers who need fast, reliable data without taking unnecessary risks.
How Do Drones Conduct Thermal Surveys?
Here’s how we typically run a drone survey at Balmore Group:
- Planning & Permissions: We review the site, conduct risk assessments, and ensure flight paths comply with CAA regulations.
- On-Site Survey: Our licensed drone pilots use UAVs fitted with FLIR thermal cameras to scan your site.
- Image Processing: We analyse both visual and infrared data to highlight potential problem areas.
- Report & Advice: You’ll receive a detailed report with images, findings, and our recommendations, whether it’s roofing repairs, insulation upgrades, or further investigation.
We integrate this process seamlessly into our full range of roofing services in Glasgow, so whether you need advice, repair or follow-up work, we’re already on-site and ready to go.
How Much Does a Thermal Drone Survey Cost?
Drone inspection pricing varies depending on:
- Size of the site
- Level of detail required
- Complexity (i.e. confined spaces, altitude restrictions)
- Deliverables (basic imagery vs. full diagnostic reports)
Typical costs might be:
- Residential roof scan: £350–£600
- Mid-sized commercial property: £800–£1,500
- Large industrial sites: £2,000+
We’ll always offer a custom quote upfront with no surprises. And because we’re a full-service roofing contractor in Glasgow, we can bundle inspections with repair work, saving time and cost
How Long Does a Thermal Imaging Survey Take?
Most surveys take between 1–3 hours, depending on site size. Data processing and analysis usually take an additional 24–48 hours, after which you’ll receive your detailed report.
Thanks to drones, even large commercial roof scans can be completed with minimal disruption to your day-to-day operations.
Is a Thermal Imaging Survey Worth It?
In short, yes. For homeowners, businesses, and developers alike, thermal imaging provides a quick return on investment through:
- Lower repair costs
- Better energy performance
- Peace of mind (especially during winter or post-storm)
- Reduced operational downtime
- Solid data for decision-making or insurance claims
We’ve worked with roofers across Glasgow, property owners, councils and conservation bodies, and nearly all of them report significant value from their investment.
