Thermal roof surveys for homes and businesses in Lenham
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. The camera doesn’t see water itself, so findings are checked with moisture readings. Thermal imaging is included in our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. If you are worried about gaps in loft insulation and wet areas near outlets and upstands, we can find out what’s behind it.
In smaller places like Lenham, many homes are bungalows and houses with roofs you can partly see from ground level. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. The forecast decides the day, as calm, dry conditions suit both. Close-up images often show wear on ridges, verges and flashings that can’t be judged properly from ground level.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Common questions in Lenham
Do you cover Lenham?
Yes, Lenham is within the area we cover. We survey roofs across London and the South East. You can ring 07833 053749 or drop us an email with the address and some details, and we’ll talk through which survey suits.
Will you come out to Lenham?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Are you structural engineers?
No. Our survey is not a structural engineer’s report, and it doesn’t include calculations. We’ll recommend an engineer if we see signs that call for one.
Will you fly a drone over my roof?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Will the camera show exactly where the water is?
No, not on its own. It shows surface temperature, and wet areas can show up because they hold heat differently. That’s why we check any patterns with moisture readings.
What does a thermal roof survey show?
It records surface temperature across the roof. Differences can suggest wet areas, missing insulation or heat loss, which we then check with moisture readings.

Do you need a thermal roof survey in Lenham?
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, particularly when there’s a clear difference between inside and outside.
These are some of the problems a survey can pick up:
- Areas losing heat at the eaves and junctions
- Damp where roofs meet walls and chimneys
- Moisture around outlets and upstands
- Areas of a flat roof that may hold water
For site and facilities teams at buildings such as Lenham Primary School, thermal images can show where wet insulation sits under a big flat roof.
Before booking any roof surveyor
- Whether you can ask questions once you have the report
- What exactly goes into their report
- What the survey will not cover
- How they’ll see the roof: from the ground, the loft, the roof or by drone
Practical tips
There’s plenty you can do without going near the roof. What helps most:
- Move stored items away from the loft hatch
- Leave the roof to people with safe access
- Take photos of stains as they appear, so we can compare
- Keep a record of when stains appear
We note the weather and surface conditions, and how they may have affected the results. It helps you judge how firm each finding is.
Clear outlets and gutters regularly, so water does not sit on the roof. The less water sits, the less can find its way beneath.
Why act early in Lenham
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. That helps you and your roofer decide what really needs replacing. Arranging work in a smaller place like Lenham is easier with notice than in an emergency. Knowing early gives you time to get the right people in.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Prices start from £400, including VAT.

Drones, thermal imaging and Lenham roofs
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Many roofs like these cannot be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
If you live in an older home near St Mary's Church, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image. Historic houses such as Leeds Castle, about 3.6 miles west, show how far back building around Lenham goes. Photos from the air and thermal images let an old roof be checked without anyone disturbing it.

What happens on the day
Every roof is different; as a rough guide, the survey takes between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. You are welcome to ask questions while we are there. In a smaller place like Lenham, as anywhere, the forecast plays a part: the parts that need calm, dry weather are planned around it.
- You tell us about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
Before we arrive
- Let us know about parking before the day
- Make a note of anything you’d like us to look at
- Have any paperwork from past roof work to hand

Where a roof is shared: we need access agreed with the freeholder or managing agent. Mention it when you contact us and we will plan the visit with that in mind.
What affects the cost of thermal roof surveys
A few things affect what a survey costs:
- Building height and the viewpoints available
- Basic, Standard or Premium
- Features like valleys, chimneys, dormers and parapets
- Any need for thermal images or a drone flight
Every price we give includes VAT, and the written report is part of the package. Our price is from £400, including VAT. Size, height and access decide where your roof falls.
