Lewknor Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof for Lewknor, from an experienced roof surveyor. Every survey comes with a written report and photos.
- Gaps in loft insulation

- Heat escaping through the roof
Prices for thermal roof surveys in Lewknor
A few things affect what a survey costs:
- The type of building, from a house to a block or an office
- Whether thermal imaging or a drone is needed
- The roof’s overall size
- Height and safe access
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. We’ll give you the figure before anything is booked.

Here’s what helps us most when you get in touch:

- Your postcode, so we can check access and travel
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, ring 07833 053749 or drop us an email.
Thermal roof survey in Lewknor
A thermal camera can help when the cause of damp isn’t obvious. Water can travel some distance under a roof covering before it shows inside, and the camera can show patterns that help us follow it. The images are used alongside a visual inspection and moisture readings, so no conclusion rests on one method alone. If you’ve noticed patches of heat loss across the roof and gaps in loft insulation, a survey will tell you what’s going on, on pitched roof slopes, loft conversions and commercial roofs alike.
Older buildings in small places like Lewknor may be listed or in a conservation area. A look by drone or thermal camera does not touch the roof, which suits a building where any change needs care, before anyone decides what work it needs. Check with the council before planning any work on a listed building or one in a conservation area.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

What happens if roof problems are left?
Buyers get extra information from thermal images that the eye can miss. Hidden problems found before exchange can be raised with the seller or agent. Older cottages and farmhouses around Lewknor can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Thermal roof survey starts from £400, including VAT.

Lewknor: your questions answered
How do I find out if my home in Lewknor is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you carry out roof surveys in Lewknor?
Yes, Lewknor is within the area we cover. We work right across London and South East England. You can ring 07833 053749 or send us an email with the address and some details, and we’ll talk through which survey suits.
Can you check my loft insulation with a thermal camera?
The camera can point to heat loss and gaps in insulation. We don’t give energy ratings or heat loss calculations, but the images show where improvements may help.
How do I arrange a thermal roof survey in Lewknor?
To book, call 07833 053749 or drop us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.
Can a thermal camera see water?
The camera doesn’t see water itself. Because wet insulation holds heat for longer, it can show as a different temperature, and moisture readings are used to check it.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you when booking.
What conditions are best for thermal imaging?
The weather makes a real difference. It works best after a sunny day, with a dry roof surface and little wind. Rain, wind and heavy cloud can weaken the patterns, so we discuss the forecast when booking.
The survey, step by step
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can safely be seen, from ground level, from windows, in the loft space and by drone where it applies. Most surveys take about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Around Lewknor, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We carry out a visual inspection of the roof from wherever it can be seen safely.
- Thermal images are taken to show differences in surface temperature.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- You get a report with thermal images, photographs and our recommendations.
Getting ready for the survey
- Gather any invoices or paperwork from past roof work
- Let us know about any leaks, stains or damp patches you know of
- If you are buying, let the agent know when we are coming

DIY checks: what’s safe
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That is where a survey comes in, using safe viewpoints and a drone where applicable.
It is useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
Surveys for landlords and agents in Lewknor
Letting agents can arrange access with tenants. We survey on weekdays and at weekends, which helps when tenants work during the week.
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time.
Roof by roof
Felt and asphalt flat roofs
These coverings sit directly on the layers beneath, so temperature differences often show through. Any patterns are checked with moisture readings.
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. The camera can show where it no longer covers the ceiling.

Thermal roof surveys in Lewknor: local notes
West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
If you live in an older home near Church of St Margaret, 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. Take a building like Lewknor Church of England Primary School: a drone or thermal camera can show a large roof in a single visit. With Adwell House about 1.6 miles north-west, the area around Lewknor has a long history. Close-up aerial shots and thermal images let an old roof be checked without anyone disturbing it.
