Thermal imaging roof survey in Childs Hill, Greater London
Get a clear view of the roof at a property in Childs Hill. We visit on weekdays and at weekends.
- Damp around chimneys and parapets
- Wet insulation beneath the membrane
- Leaks that are hard to trace
When you need someone else
We only report whatever is safely visible on the day, so there are some things a survey cannot cover:
- Readings unaffected by sun, shade or reflections
- Proving moisture from the images alone
- The condition of timbers we cannot see
If in doubt, ring 07833 053749 or drop us an email and we’ll point you to the right survey. What our survey covers.

Thermal roof survey in Childs Hill
A thermal survey can point to places where heat is escaping through the roof. Missing or slipped insulation and gaps at the eaves often show up as temperature differences. It works best when the building is heated and it is colder outside. Our report points out what the images suggest and where to look more closely. We do not give energy ratings or heat loss calculations. We survey insulated roof spaces, loft conversions and commercial roofs, and common reasons people get in touch are stains that keep coming back and damp around roof outlets and upstands.
London airspace is busy and tightly controlled: restriction zones surround Heathrow, London City Airport and London Heliport, and Hyde Park, the City of London and the Isle of Dogs have restricted areas of their own. Every address in Childs Hill is checked before any drone flight, and where permission is needed, the flight waits for it.
What you get is a clear record of the roof on the day we saw it. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

Checking the roof from the ground
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That’s where a survey comes in, using safe viewpoints and a drone where it applies.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Common roof problems in Childs Hill
Once a leak has been fixed, people often ask whether the roof is still wet. A thermal survey with moisture readings can show whether wet areas remain when the conditions on the day are suitable.
Problems we come across often include:
- Damp where roofs meet walls and chimneys
- Damp that repairs haven’t cured
- Water that travels before it shows
- Patches of heat loss across the roof
Anyone responsible for a site like All Saints' CofE Primary School NW2 will know that thermal images can show where wet insulation sits under a big flat roof.
Before you book anyone
- Whether you can ask questions once you have the report
- Whether the loft space is looked at, where there is one
- How much experience they have with roofs like yours
- Which parts of the roof they’ll actually see
Why get it checked now?
A poorly insulated roof loses heat year after year. Thermal images can show where insulation is missing or has slipped, so you know where to put things right. In Childs Hill, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Dealing with it early is far less disruptive.
Our price is from £400, including VAT. What you pay depends on how big and how high the roof is, access and which survey you book.
Why us?
- Surveys seven days a week
- An independent view of the roof
- Two decades and more of roof surveys
- More than 5,000 surveys completed

How the survey works
We do not take risks to get a closer look. We inspect what can be seen safely, and if part of the roof can’t be seen, the report says so. Most visits take an hour or two for most homes, plus time to check any thermal findings with moisture readings. In Childs Hill, as in much of London, a good many properties are flats or terraces without side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when you book.
- First we discuss the roof, any damp and the forecast for the visit.
- We look over the roof from wherever it’s safe.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
Before we arrive
- For a flat or shared roof, check access with whoever owns or manages the building
- Keep pets in another room
- Find any records of previous roof work
Getting a price
A quick phone call is normally the easiest start: ring 07833 053749 or send us an email and we will ask a few questions about the roof. The price is agreed before a date is set.

Thermal roof surveys around Childs Hill
With Heath House about 0.7 miles east, Childs Hill sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Within a mile and a half or so of Childs Hill there are several hotels, and like offices and blocks, hotels often sit under flat roofs. If you look after one, a large roof can be surveyed without guests having anyone working above them.
The streets around a church such as All Saints are frequently among the oldest in a place, and if yours is one of the older homes nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view by drone or thermal camera helps. A roof leak in a hotel or guest house around Childs Hill means lost rooms as well as repairs, so it is worth knowing the roof’s condition.

Questions from Childs Hill
Is parking a problem for a survey in Childs Hill?
Sometimes, yes. If Childs Hill has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Does a conservation area affect roof work in Childs Hill?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a 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.
Can you inspect my roof with a drone?
Where it is applicable and safe, yes. We’re a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It is included in the Drone Roof Survey and, where applicable, the Premium Survey.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we don’t provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Is thermal imaging good for finding leaks?
It can help narrow down where water may be getting in. Patterns can suggest where trapped water has spread. We combine it with a visual inspection and moisture readings because the camera can’t confirm water on its own.
Does thermal imaging detect leaks directly?
No, not on its own. It shows temperature, and wet materials often behave differently from dry ones. We confirm what it suggests with moisture readings.
How do I arrange a thermal roof survey in Childs Hill?
The quickest way is to phone 07833 053749 or email us. Give us the address and a few details about the roof, and we’ll recommend the right survey. Surveys run on any day of the week.
How the survey changes by roof type
Parapets, valleys and junctions
Damp at junctions can be hard to see by eye. We combine a close visual check with the thermal images.
Loft insulation
In the roof space, the camera can pick up gaps and thin areas of insulation. We look where there is safe access.
