Thermal Roof Survey in South Hampstead
Thermal imaging to find moisture and heat loss patterns in a roof in South Hampstead, using drones and thermal imaging where it applies. Call or email for a price.
- Stains that keep coming back
- Damp where roofs meet walls and chimneys
- Cold spots on ceilings under the roof
What a survey costs
Several things affect the price of a survey:
- Features like valleys, chimneys, dormers and parapets
- Height and safe access
- Whether thermal imaging or a drone is needed
- The type of building, from a house to a block or an office
Our price is from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, including VAT.
What we need to know
There’s no need for technical words. Just let us know:
- Where water is showing inside, if it is
- What made you get in touch
- What kind of property and roof it is
- Any photos you have, taken from ground level or a window
When you’re ready to go ahead, call 07833 053749 or email us. From there it is a case of choosing a package, agreeing the price and fixing a day.
Thermal roof survey in South Hampstead
Your report sets out the thermal images alongside ordinary photos, making it clear where on the roof each pattern is. Each one comes with an explanation, the moisture readings and our recommendation. With a Premium Survey, the report reaches you the same day. You can talk the findings through with us at the in-person consultation. There’s a 12-month follow-up as well. Typical surveys look at missing or slipped insulation and wet insulation beneath the membrane, on loft conversions, insulated roof spaces and ceilings below the roof.
In London’s terraces and conversions, roofs are packed close together, so privacy and neighbours matter as much as the view. Images are taken to show the roof we’re surveying, with care for neighbours’ privacy, in South Hampstead as anywhere. Mention access, height and anything unusual about the building as you book. The extra view helps most on steep slopes, tall stacks and rear additions.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that is said too.

Flying and imaging in South Hampstead
The wider area around South Hampstead has a long history of building, with Winfield House about 0.9 miles south-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
If you look after a shop, office or commercial unit, for instance near O2 Centre, a commercial roof can be photographed from above without anyone walking on it. Controlled parking zones are common in London, so mention any permit rules for South Hampstead. Hotels and guest houses near South Hampstead cannot easily close rooms for a leak, so it is worth knowing the roof’s condition.
South Hampstead is about 1 mile south of Hampstead, in Greater London. From houses to flats and shops in South Hampstead, we can survey the roof on a weekday or at the weekend. South Hampstead is one of the places in Greater London we cover.
Surveys in NW3, NW8 and NW6 work the same way as everywhere else we cover. You will find streets such as Avenue Road, Acacia Road and Harben Road. If you’re just outside South Hampstead, we cover Swiss Cottage (1 mile north), St John's Wood (1 mile south), Haverstock (1 mile east), Belsize Park (1 mile east) and Primrose Hill (1 mile east). Further out, we also cover London (4 miles south-east), Kensington (3 miles south-west), St Pancras (3 miles south-east), Shoreditch (4 miles east), Walthamstow (7 miles north-east) and Hoxton (4 miles east).
Local landmarks in South Hampstead
Around South Hampstead, our work takes us to homes and buildings near Cafe Med pub, St. Mary's Town and Country School and Holy Trinity CofE Primary School. Nearby too are Cecil Sharp House (1.1 miles east) and Primrose Hill (0.6 miles east). There’s a railway station in South Hampstead itself: South Hampstead station. A little further out are Isokon Gallery (0.8 miles north-east) and O2 Centre (0.5 miles north-west). For a walk, there’s Adelaide Nature Reserve and The Long Water.
How the survey changes by roof type
Single-ply and EPDM roofs
On larger commercial single-ply roofs, thermal imaging can help target moisture readings. That makes the survey more focused.
Loft insulation
Insulation often gets moved during work in the loft. Thermal images can show where it has been pushed aside.
Tips from our surveys
Nothing here needs a ladder. A few suggestions:
- Keep a record of when stains appear
- Clear leaves from outlets and gutters each autumn
- Heat the home normally on the days before
- Keep dated photos of any marks on ceilings
After the visit, we put the thermal images, photographs and moisture readings into one report. We explain what each image may mean, with our recommendations. Premium reports are sent the same day.
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 South Hampstead
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. It helps when deciding whether to patch an area or replace the roof. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
Prices start from £150, including VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the price for your survey before booking.

South Hampstead: your questions answered
Can you fly a drone over a roof in South Hampstead?
It depends on the exact address and the weather on the day. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Each address is checked against all of them before the drone goes up. Before any flight, we check the Drone Safety Map for airspace restrictions. The flight also waits for calm, dry weather, though the rest of the survey goes ahead either way.
How do I find out if my home in South Hampstead 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. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
Can you tell me if my roof has asbestos?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Will you walk on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest, and the report records anything we couldn’t see.
How long does the survey take?
Time on site depends on the roof, but most surveys take roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. The written report follows by email.
Will thermal imaging find my leak?
Thermal imaging can help, alongside other checks. The results depend on conditions on the day. Where it can’t be pinned down, the report suggests a next step, like electronic leak detection.
The survey, step by step
Once we have finished looking, we write up our findings as a written report with photos, sent to you by email. As for time on site, most surveys take roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents as you book.
- You tell us 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.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
How to prepare
- Clear the way to the loft hatch
- If you are buying, check with the agent that we can get in
- Let us know where we can park nearby
