Thermal imaging to find moisture and heat loss patterns in a roof in Walton on the Hill, using drones and thermal imaging where applicable. Get in touch for a price.
- Cold spots on ceilings under the roof
- Water that travels before it shows
- Damp where roofs meet walls and chimneys
What we do, step by step
The visit has one job: to see as much of the roof as can safely be seen and record it clearly. Notes and photographs go into the written report. It usually takes between one and two hours for most homes, plus time to check any thermal findings with moisture readings. Older roofs in small places like Walton on the Hill can have low, tight loft spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- 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.
- The Premium report reaches you the same day, and we go through it with you in person.
Before we arrive
- Mention any parking restrictions on your street
- If you’re buying, check with the agent that we can get in
- Leave a clear route to the loft
Getting a price
If you have photos of the roof, send them over. Pictures from ground level or a window are fine; never climb up to get a better view. To get started, call 07833 053749 or send us an email.

How a thermal roof survey works in Walton on the Hill
Thermal imaging is part of our Premium Survey, which starts from £400. You also get a drone inspection where it applies, structural analysis and a report on the same day. There is an in-person consultation as well, plus a follow-up 12 months later. You can call 07833 053749 or send us an email with the address and a note of what you’ve noticed. For big commercial roofs, we quote on size and access. We survey commercial roofs, insulated roof spaces and ceilings below the roof, and people most often book us about damp around chimneys and parapets and thin or uneven insulation in the roof.
Some older homes in villages like Walton on the Hill are listed or in a conservation area. A look from above or with a thermal imager doesn’t touch the roof, so it’s a gentle way to see the condition of an old roof. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

When to book a survey in Walton on the Hill
Building owners and managing agents use thermal surveys to plan work on larger flat roofs. It can suggest which areas may be wet and which seem dry, so moisture readings can be targeted.
We’re frequently asked to look at:
- Damp patches with no obvious cause
- Areas losing heat at the eaves and junctions
- Water getting in at parapets and stacks
- Leaks far from where the stain appears
If you look after a building such as Walton-on-the-Hill Primary School, thermal images can show where wet insulation sits under a big flat roof.
Questions to ask before you book
- Which viewpoints they use to see the roof
- What experience they bring
- Their report turnaround times
- What the report includes, and whether it has photos

Before and after the survey

- Keep the report to compare against after any repair
- Talk to us about the weather when booking
- Keep dated photos of any marks on ceilings
- Clear a path to the loft hatch before we arrive
Once we have been, the thermal images, photos and readings go into a single report. We explain what each image may mean, with our recommendations. With a Premium Survey, you get the report the same day.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Gaps frequently appear after work in the loft.

Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on, photographs included.
What a survey costs
When we price a survey, we consider:
- Building height and the viewpoints available
- The use of thermal imaging or a drone
- Basic, Standard or Premium
- The roof’s overall size
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.
Helping us price your survey
Before you get in touch, it’s useful to have:
- Whether there is a loft hatch, a shared roof or tricky access
- The property’s address and postcode
- Why you want a survey: buying, a leak, a storm or new work
- Where any leaks, stains or damp patches show inside
Thermal roof survey starts from £400, including VAT. The exact figure depends on the roof and the package, and you can call 07833 053749 or send us an email to find out.
How the survey changes by roof type
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below often show. Shiny surfaces can reflect heat, so we take care reading the images.
Loft insulation
The difference is clearest when the home is heated and it’s cold out. Our report notes how the conditions affected the images.
Your questions about thermal roof surveys in Walton on the Hill
Do you cover Walton on the Hill?
Yes. We work right across London and the South East, and Walton on the Hill is part of that. You can ring 07833 053749 or send us an email with the address and some details.
How do I find out if my home in Walton on the Hill is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Will thermal imaging find my leak?
It can help narrow down where water may be getting in. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. It is used alongside a close inspection and moisture readings because the camera can’t confirm water on its own.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
What will the report tell me?
A written report with photos, covering the condition of the roof, the defects we found and what we recommend. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
Will I get photos?
Yes, every report has them. Each finding is shown in a picture where possible, which makes the report easy to follow.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance.
