Thermal roof survey in Exeter
Professional thermal roof survey services in Exeter and surrounding areas. Local, reliable handyman - no job too small.
Location
Exeter, Devon
Thermal imaging survey of your roof using radiometric thermal camera on our DJI Matrice 4 Thermal. Reveals hidden heat loss, moisture trapped in the structure, and insulation failures - problems invisible to the naked eye.
See What's Hiding Under Your Roof
Your roof might look fine from the outside. But what's happening underneath? Trapped moisture silently rotting timbers. Missing insulation letting your heating bill soar. Failed membranes letting water in drip by drip.
A thermal camera sees what you can't.
💡 Pro tip: The best time for thermal roof surveys is during cooler months (Oct-Mar) when the temperature difference between inside and outside is greatest. Early morning flights often give the clearest results.
What Thermal Imaging Reveals
| Problem | How It Shows |
|---|---|
| Heat loss | Bright spots where warmth escapes through the roof |
| Wet insulation | Areas that hold heat differently to dry sections |
| Missing insulation | Hot patches amid cooler, well-insulated areas |
| Membrane failure | Moisture patterns under flat roof coverings |
| Blocked ventilation | Temperature anomalies around ridge and eaves |
Visual vs Thermal
| ✅ Thermal Imaging | ❌ Visual Only |
|---|---|
| Sees beneath the surface | Only shows visible damage |
| Detects moisture before it causes visible damage | Finds leaks after the damage is done |
| Maps insulation performance | Can't tell if insulation is working |
| Quantifies heat loss | Guesswork at best |

What to Expect
Step 1: Briefing & Setup
I discuss what you're concerned about, check weather conditions (cloud cover and wind matter for thermal), and plan the survey approach.
Step 2: Thermal & Visual Flight
The drone captures both thermal and visual imagery of your entire roof. The thermal camera records precise temperature data at every point - not just pretty colours.
Step 3: Analysis & Report
Thermal images are reviewed and annotated. You get a clear report showing any heat loss zones, moisture areas, or insulation gaps - with recommendations for what to do next.
🔧 DIY Tips
You can spot some heat loss signs without a drone:
🔧 What to look for
- Snow melting unevenly on your roof (hot spots melt first)
- Ice forming at the eaves (sign of heat loss through the roof)
- Some rooms noticeably colder than others upstairs
- High energy bills despite recent insulation work
- Damp patches on bedroom ceilings
📐 Simple checks
- Go into the loft on a cold day - can you feel warmth? That's heat escaping
- Check insulation depth - should be 270mm for modern standards
- Look for gaps around pipes, hatches, and where walls meet the roof
- Feel around windows in the roof for draughts
⚠️ Limitations
- You can't see moisture trapped in the structure
- Visual checks miss partial insulation failures
- Ground-level thermal cameras can't see the roof properly
💡 Pro trick: On a frosty morning, look at your roof from the street. Areas where frost melts first are losing the most heat. It's a free thermal survey, just less precise.
Rather leave it to a pro? No problem - that's what I'm here for. Give me a call.
Good to Know
🏠 Energy bills through the roof? (Pun intended.) A thermal survey pinpoints exactly where you're losing heat, so you can fix the right areas instead of guessing. Many customers recoup the survey cost within a single winter through targeted insulation improvements.
Combine with visual inspection for the complete picture - surface damage plus hidden problems in one visit.
Older Exeter properties benefit most from thermal surveys. Solid walls, original slate roofs, and retrofitted insulation that may have settled or been installed poorly - thermal imaging reveals it all.
Frequently Asked Questions
What does a thermal roof survey actually show?
The thermal camera detects temperature differences across your roof surface. Hot spots indicate heat escaping through poor insulation. Cold spots on the interior side show where heat isn't reaching. Wet areas show up differently to dry areas because moisture changes the thermal signature. You get a colour-coded image that makes problems obvious.
When is the best time of year for a thermal survey?
October to March is ideal - you need a decent temperature difference between inside and outside for the best results. Early morning or late afternoon works well. That said, moisture detection works year-round because wet areas hold temperature differently regardless of season.
Can it find where my roof is leaking?
It can identify areas of moisture in the roof structure, which is often the first step in finding a leak. Water travels along rafters and membranes, so the wet area shown on thermal may not be directly below the entry point - but it narrows things down massively.
How is this different from a visual drone inspection?
A visual inspection shows surface damage - cracked tiles, lifted flashings, loose ridges. Thermal imaging reveals what's happening underneath - trapped moisture, insulation gaps, heat escaping through the structure. Ideally you want both for the complete picture.
Do I get a report I can show my builder?
Yes - you get annotated thermal images alongside normal photos, with a written summary explaining what each area shows. Builders, roofers, and insulation contractors can use this to quote accurately for any remedial work needed.
