What a thermal roof survey looks like in Walham Green
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. If your home in Walham Green is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Many roofs like these can’t be judged properly from the pavement, and that is where a view from above or a thermal image earns its place. Within a mile and a half or so of Walham Green there are several hotels, and like offices and blocks, hotels frequently sit under flat roofs. If you look after one, a large roof can be surveyed without guests having anyone working above them.
If you look after a shop, office or commercial unit, for instance near Putney Exchange, big, flat commercial roofs are where aerial photos and thermal images help most. With Carlyle's House about 1 mile north-east, the area around Walham Green has a long history. Older roofs nearby can be steep and hard to see from the ground, and a survey from the air or with a thermal camera doesn’t touch the roof itself.
Walham Green is about 2 miles south of Kensington, in Greater London. We survey roofs in Walham Green and the rest of Greater London. Walham Green is one of the towns and villages in Greater London where we work for thermal roof surveys.

Thermal roof surveys for homes and businesses in Walham Green
Thermal imaging is useful when a damp patch has no clear cause. Water can travel some distance under a roof covering before it shows inside, and temperature patterns can help us trace where it may have come from. The images are used alongside a visual inspection and moisture readings, so no conclusion rests on one method alone. If you’ve noticed leaks far from where the stain appears and patches of heat loss across the roof, a survey will tell you what’s going on.
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 Walham Green is checked before any drone flight, and permission is never taken for granted.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

What else we do in Walham Green
What a thermal roof survey does not cover
No survey can tell you everything, and it’s better to know them up front. Bear these in mind:
- Insulation values or heat loss calculations
- Reliable images in rain, strong wind or on a wet roof surface
- Hidden layers that need to be opened up to check
Not sure which survey suits your roof? You can phone 07833 053749 or drop us an email and we’ll tell you. What a survey covers and does not.
Roofs we survey in Walham Green
- Insulated roof spaces
- Flat roofs
- Loft conversions
- Pitched roof slopes
- Ceilings below the roof
- Commercial roofs
How the survey works
There is not much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll take it from there. The survey itself takes about 1–2 hours for most houses, with bigger or more complicated roofs taking longer. In Walham Green, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, tell us when booking.
- You let us know about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- 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
- Unlock side gates and any roof access doors
- Make sure the loft hatch can be reached
- Tell us where we can park nearby

What you can safely check yourself
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Practical tips
Here are a few things we’d tell any owner, before and after a survey:
- File the images with your roof records
- Check outlets after heavy rain
- Remember the conditions on the day affect the results
- Keep the heating on as usual before a heat loss survey
You can pass the report to a roofer so they can see where the problem areas seem to be. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Clear outlets and gutters regularly, so water doesn’t sit on the roof. Less standing water means less chance of it getting under the covering.
Signs you need a thermal roof survey in Walham Green
Building owners and managing agents use thermal surveys to plan work on larger flat roofs. Patterns can point to wet areas and show which parts look sound, so we know where to take moisture readings.
Problems we come across often include:
- Areas losing heat at the eaves and junctions
- Damp patches with no obvious cause
- Leaks far from where the stain appears
- Ceilings that feel colder in places
Walham Green is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier.

Walham Green questions
How do I find out if my home in Walham Green is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. 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 fly a drone over a roof in Walham Green?
It depends on the exact address and the weather on the day. Walham Green is inside, or right on the edge of, the flight restriction zone around London Heliport in Battersea. We ask the heliport for permission before flying there, and only fly if it’s given. London’s airspace includes flight restriction zones around Heathrow, London City Airport and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. A small drone cannot fly safely in high wind or heavy rain, and the rest of the survey doesn’t depend on the drone.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
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, but we check each finding with moisture readings.
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. If one is needed, the report says so.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Is thermal imaging good for finding leaks?
Thermal imaging can help, alongside other checks. What it shows depends on the weather and the roof. If the source cannot be confirmed, we’ll say what could help next, such as electronic leak detection.
