Thermal roof surveys for homes and businesses in Anstey
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera does not see water itself, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. If you’re worried about moisture around outlets and upstands and damp patches with no obvious cause, we can find out what’s behind it, on commercial roofs, ceilings below the roof and pitched roof slopes alike.
Older buildings in small places like Anstey may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, which suits a building where any change needs care, before anyone decides what work it needs. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
Every survey ends with a written report, with photos, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

Signs you need a thermal roof survey in Anstey
After a repair, some owners want to know whether the roof has dried out. Thermal images and moisture readings can suggest whether moisture is still trapped, given suitable conditions on the day.
A survey makes sense if you’ve noticed:
- Thin or uneven insulation in the roof
- Damp patches with no obvious cause
- Damp where roofs meet walls and chimneys
- Moisture around outlets and upstands
The streets around a church like Church of St George are often among the oldest in a place, and if your home is one of the older ones nearby, thin or patchy insulation under an old roof often shows up clearly on a thermal image.
Choosing a roof surveyor
- What’s outside the scope of the survey
- What exactly goes into their report
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Will they check the loft as well as the outside?
Practical tips
A few practical points come up again and again on our surveys. They apply to most roofs:
- Clear a path to the loft hatch before we arrive
- Keep dated photos of any marks on ceilings
- Note where damp appears and after what weather
- Clear leaves from outlets and gutters each autumn
Premium Surveys include an in-person consultation, giving you the chance to talk through the images and findings. There is a 12-month follow-up too.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
Questions from Anstey
Is my home in Anstey listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover Anstey?
Yes. Our area covers London and the South East, and Anstey is part of that. You can ring 07833 053749 or use the contact form with the address and some details.
Are you insured?
We are covered by professional indemnity and public liability insurance.
Can you give me structural calculations?
No. We note visible signs like sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Does someone need to be in?
Not necessarily. If we only need the outside, we can agree that ahead of time, but the loft and any rooms with damp need someone to let us in.
Does the report include photographs?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
What does a thermal roof survey show?
The images show how warm or cool each part of the surface is. Differences can suggest wet areas, missing insulation or heat loss, which we then check with moisture readings.
Flying and imaging in Anstey
England has around 10,000 conservation areas and about 500,000 listed buildings. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
Take a building like Anstey First School: a drone or thermal camera can show a large roof in a single visit.

What we do, step by step
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey normally takes roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. For a village or hamlet like Anstey, the journey is planned in advance: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
Before the survey
- Mention any parking restrictions on your street
- If you’re buying, let the agent know when we are coming
- Note where any stains or damp appear
