Crowell Thermal Roof Survey
Thermal roof surveys for homes and businesses in Crowell. We’ve completed more than 5,000 surveys across London and the South East.
- Damp around chimneys and parapets
- Water that travels before it shows
- Damp patches with no obvious cause
Tips that help
These tips come from what we see on roofs every week:
- Talk to us about the weather when booking
- Move stored items away from the loft hatch
- Check from ground level or a window, never by climbing
- Photograph damp patches with the date
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it is easy to find each area on the roof.
Deal with small splits and lifted seams promptly. Once water gets under a membrane, it can travel far before it appears inside.
Thermal roof surveys for homes and businesses in Crowell
Our thermal survey records how the surface temperature varies across your roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It is important to know that the camera shows temperature, not water, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. We survey flat roofs, commercial roofs and loft conversions, and people most often book us about wet areas near outlets and upstands and water that travels before it shows.
Older buildings in small places like Crowell 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. Check with the council before planning any work on a listed building or one in a conservation area.
The report works through the roof section by section, from the main slopes down to the gutters and outlets. It records what’s sound as well as what is not.

What else we do in Crowell
Different roofs, different checks
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. The camera can give clues to where it is sitting, given suitable conditions on the day.
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are often laid over insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
How we price thermal roof surveys
Survey packages start from £150, with VAT included. The price for your roof depends on:
- The height of the building and how the roof can be seen safely
- If the survey needs thermal imaging or a drone
- How big the roof is
- Whether you choose the Basic, Standard or Premium Survey
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.
Booking your survey
What helps most when you contact us:
- Where the property is, with the postcode
- Any marks or damp showing indoors
- Access details, such as a loft hatch or a shared roof
- Any deadline, such as an exchange date
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, call 07833 053749 or email us with the address and the days you’d prefer.
Thermal roof surveys around Crowell
Historic houses like Adwell House, about 2.9 miles west, show how far back building in the area around Crowell goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
If you live in an older home near Church of the Nativity of the Blessed Virgin Mary, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view from the air or with a thermal camera helps. Anyone responsible for a site like Mill Lane Community Primary School will know that a view from above covers a wide roof far faster than walking it.
Crowell is about 4 miles south-east of Thame, in Oxfordshire. We survey roofs in Crowell across London and South East England. Crowell is one of the places in Oxfordshire we cover for thermal roof surveys. We also survey roofs in Oxford.

Your questions about thermal roof surveys in Crowell
How do I find out if my home in Crowell is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Crowell?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
What happens after the survey?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Will you go up on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the loft space and a drone where it applies, and the report records anything we couldn’t see.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. We’ll talk about access as you book.
How do I arrange a thermal roof survey in Crowell?
To arrange a survey, call 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Can a thermal survey trace a roof leak?
Thermal imaging can help, alongside other checks. The results depend on conditions on the day. If the source can’t be confirmed, we’ll say what could help next, like electronic leak detection.
The survey, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Somewhere like Crowell needs a little journey planning: 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.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We carry out a visual inspection of the roof from wherever it can be seen safely.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there’s safe access.
- We write up the thermal images alongside ordinary photos and recommendations.
Getting ready for the survey
- For a flat or shared roof, check access with whoever owns or manages the building
- Jot down any questions you want answered
- Have keys ready for side gates, garages or roof access doors
Booking a survey
If you’re buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just call 07833 053749 or email us when you are ready.
