Thermal roof survey in South Kensington
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. This can give an idea of how far water has travelled beneath the membrane, which is hard to judge by eye. We then check those areas with moisture readings. If you are worried about cold areas below the roof and stains that keep coming back, we can find out what’s behind it, on ceilings below the roof, pitched roof slopes and flat roofs alike.
In London’s terraces and conversions, roofs are packed close together, which makes care around neighbours part of the job. We take care to focus on the roof we have been asked to look at, in South Kensington as anywhere. Mention access, height and anything unusual about the building when you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
After the visit, you get a written report with photos, emailed to you. It sets out the condition of the roof, any defects and our written recommendations.

Tips that help
You don’t need to be a roofer to help. What helps most:
- Talk to us about the weather when booking
- Check outlets after heavy rain
- Keep a record of when stains appear
- Clear a path to the loft hatch before we arrive
You can pass the report to a roofer so they can see where the problem areas seem to be. Because the images are paired with photos, it is easy to find each area on the roof.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
Why get it checked now?
Heat lost through a roof costs money every winter. The camera can point to gaps and thin areas in the insulation, so you know where to put things right. In South Kensington, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.
The Premium Survey includes thermal imaging and drone inspection where it applies, from £400 inc. VAT. We will tell you which package suits the questions you have.
Why us?
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- Thermal imaging and drones used where they help
- Package prices that include VAT
- A photo-illustrated written report

Landlords, agents and block managers in South Kensington
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Larger roofs take longer.
If you own several properties, surveys can be booked for more than one address. To arrange surveys for several addresses, call 07833 053749 or email us.
Drones, thermal imaging and South Kensington roofs
The flight restriction zone around London Heliport in Battersea covers South Kensington, or comes right up to its edge. If your survey includes the drone, we ask the heliport for permission first, and only fly if it is given. Within a mile and a half or so of South Kensington there are several hotels, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, large roofs are where photos from the air and thermal images show the most at once.
Hotels and guest houses near South Kensington cannot easily close rooms for a leak. If you run a business near Harrods, thermal images can show trapped moisture across a wide commercial roof.
South Kensington is about 1 mile south-east of Kensington, in Greater London. Wherever you are in South Kensington, we can carry out thermal roof surveys at your property, on a weekday, Saturday or Sunday. South Kensington is one of the towns and villages in Greater London we cover for thermal roof surveys.

Different roofs, different checks
Loft insulation
Heat loss shows most clearly when it’s warm inside and colder outside. Our report notes how the conditions affected the images.
Felt and asphalt flat roofs
Felt and asphalt roofs often show wet areas as patches that differ from the rest. Moisture readings are used to check them.
Common roof problems in South Kensington
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 moisture readings can be targeted.
Most people get in touch when they’ve noticed something like this:
- Heat escaping through the roof
- Cold spots on ceilings under the roof
- Areas of a flat roof that may hold water
- Thin or uneven insulation in the roof
If you live in an older home near Chapel of St Luke, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Before booking any roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether you get a written report with photos
- Is VAT included in the price?
- Which limits apply to the survey

Questions from South Kensington
Is my home in South Kensington listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will parking be an issue for a roof survey in South Kensington?
Parking in South Kensington, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Does thermal imaging detect leaks directly?
Thermal imaging shows temperature rather than water. Because wet insulation holds heat for longer, it can show as a different temperature, but we check each finding with moisture readings.
Do you climb onto every roof?
Only when it is safe. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the roof space and a drone where it applies, and the report records anything we couldn’t see.
Are you structural engineers?
No. We are roof surveyors, not structural engineers. We will recommend an engineer if we see signs that call for one.
How do I book a survey in South Kensington?
The quickest way is to call 07833 053749 or use the contact form. Give us the address and some details about the roof, and we will take it from there. We survey on weekdays, Saturdays and Sundays.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. We’ll talk about access when booking.
How the survey works
Photographs are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it is applicable and the weather allows. Most surveys take about 1–2 hours at a typical home, though large, tall or awkward roofs take more time. In a London conversion, the way into the roof space is often from a communal landing or the top flat. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- 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.
- Any patterns of interest are checked with moisture readings where we can reach them.
- We write up the thermal images alongside ordinary photos and recommendations.
Preparing for the visit
- Check the loft hatch can be reached
- If it isn’t your property yet, arrange access through the agent
- Check pets are kept safely away
