Thermal imaging roof survey in Kensal Town, Greater London
Wondering about the roof at a property in Kensal Town? We carry out thermal roof surveys in Kensal Town and across Greater London, with plain-English findings.
- Water that travels before it shows
- Damp around roof outlets and upstands
- Stains that keep coming back
Do you need a thermal roof survey in Kensal Town?
Some defects simply cannot be seen with the eye. Wet insulation, gaps in insulation and heat loss are frequently invisible from outside. Thermal imaging gives us another way to look for them.
A survey makes sense if you’ve noticed:
- Areas of a flat roof that may hold water
- Water getting in at parapets and stacks
- Thin or uneven insulation in the roof
- Moisture around outlets and upstands
If you run a business near Westfield London, large commercial roofs are frequently easiest to see by drone or thermal camera.
What to check before booking
- Is there a chance to talk the report through?
- How long they’ve been surveying roofs
- Which parts of the roof they’ll actually see
- Whether you get a written report with photos
How a thermal roof survey works in Kensal Town
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. It helps us see how far water may have spread under the covering, which is hard to judge by eye. We then check those areas with moisture readings. If you’ve noticed areas losing heat at the eaves and junctions and missing or slipped insulation, we can find out what’s behind it, on ceilings below the roof, pitched roof slopes and commercial roofs alike.
London roofs sit shoulder to shoulder in terraces and blocks, which makes care around neighbours part of the job. Images are taken to show the roof we are surveying, with care for neighbours’ privacy. Tell us about the building and access as you book. The extra view helps most on steep slopes, tall stacks and rear additions.
You receive the findings by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

What a thermal roof survey looks like in Kensal Town
Kensington Palace, about 1.6 miles south-east, is one of the historic houses in the wider area around Kensal Town. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. 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.
Take a building like St Thomas' CofE Primary School: thermal images can show where wet insulation sits under a big flat roof. For a London address like Kensal Town, it helps to know about controlled parking before the day, along with any off-street space.
Kensal Town is about 2 miles north of Kensington, in Greater London. Kensal Town is one of many places we visit across Greater London. Kensal Town is one of the places in Greater London we cover for thermal roof surveys.

Roof by roof
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are often laid over insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. Thermal imaging helps suggest where it is, when the conditions allow.
Practical tips
Most of what helps is simple and safe from ground level. A few suggestions:
- Take photos of stains as they appear, so we can compare
- File the images with your roof records
- Heat the home normally on the days before
- Ask us about the forecast if rain is expected
Once we have been, the thermal images, photos and readings go into a single report. Each image is explained in plain words, with our recommendations. With a Premium Survey, you get the report the same day.
Deal with small splits and lifted seams promptly. Water that gets under a covering can spread a long way before it shows.
How it works
On the day, we start by asking what you’ve noticed and what you’d like to know. After that, we look at everything we can see safely, from ground level, from windows, in the roof space and by drone where it applies. The survey usually takes between one and two hours for most houses, with bigger or more complicated roofs taking longer. In Kensal Town, as in much of London, plenty of 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 as you book.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there is safe access, in the loft.
- Patterns that stand out are checked with moisture readings.
- Each image is set beside a normal photo and explained in the report.
How to prepare
- Point out any leaks or damp patches
- Let us know about parking before the day
- Leave side gates unlocked
How to book
Prices start from £400, including VAT. What you pay depends on the roof’s size, access and the package, so call 07833 053749 or drop us an email with the details.

Kensal Town: your questions answered
Can parking be tricky for a visit in Kensal Town?
It rarely stops a survey, but it’s worth planning. Let us know what parking is available nearby, and the visit is planned around it.
Are there drone restrictions around Kensal Town?
That depends on where the roof is and on the weather. The flight restriction zone around London Heliport in Battersea comes within about 2 miles of Kensal Town. We check the exact boundary for the address before flying, and if the roof falls inside it, we ask for permission first. 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. High wind or heavy rain also stops a small drone flying, and the rest of the survey does not depend on the drone.
Can you use a thermal camera on a sloping roof?
It can be useful, though pitched roofs are usually harder to read. The air space under slates and tiles can hide patterns, so we also look from the loft where it’s safe.
How long will you be at the property?
It usually takes about one to two hours at most homes, and longer for a large or complex roof. We’ll confirm the timing when you book.
What happens after the survey?
You’ll receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
What’s the best way to book?
To book, phone 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Will you go up on the roof?
Only when it’s 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.
Why act early in Kensal Town
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. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Prices start from £400, including VAT. The final price depends on the size and height of the roof, access and which survey you book.
