Clapham Junction Thermal Roof Survey
We take a careful look at the roof at your property in Clapham Junction, and put it all in a written report with photographs.
- Moisture around outlets and upstands
- Heat escaping through the roof
- Damp that repairs haven’t cured
About our thermal roof survey in Clapham Junction
A thermal survey isn’t a quick fix for every roof problem. Sun, shade, reflective surfaces and wind can all change what the camera shows. That’s why we check findings with moisture readings and a close visual inspection. The report is clear about what the images show and what they do not. Where something can’t be confirmed, we say what would help next. We survey insulated roof spaces, pitched roof slopes and flat roofs, and people most often book us about stains that keep coming back and areas of a flat roof that may hold water.
London airspace is busy and tightly controlled: there are flight restriction zones around Heathrow, London City and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Before a drone goes up in Clapham Junction, the address is checked against all of them, and permission is never taken for granted.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

How the survey changes by roof type
Loft insulation
Heat loss shows most clearly when it’s warm inside and colder outside. We explain in the report how the conditions on the day affected what we saw.
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
What we can’t see
A survey is a close look at the roof, but it can’t do everything. Its limits include:
- A structural engineer’s assessment
- A formal energy assessment
- Reliable images in rain, strong wind or on a wet roof surface
Not sure which survey suits your roof? You can ring 07833 053749 or email us and we’ll tell you. What a survey covers and does not.
What this survey covers
- Loft conversions
- Commercial roofs
- Flat roofs
- Pitched roof slopes
- Ceilings below the roof
- Insulated roof spaces
How it works
Once we have finished looking, we write up our findings as a photo-illustrated written report, emailed to you. As for time on site, it typically takes between one and two hours at most homes, and about three to four hours for a commercial roof. London terraces rarely offer a view of the whole roof from one spot, so a visit in Clapham Junction moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- We start with the roof, its history and any signs of damp or heat loss.
- 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.
- The Premium report reaches you the same day, and we go through it with you in person.
Before we arrive
- Let us know about any leaks, stains or damp patches you know of
- Unlock side gates and any roof access doors
- If you’re buying, let the agent know when we’re coming
Arrange a survey
Booking is simple: just call 07833 053749 or send us an email and give us some details about the property and we will explain which survey suits. We confirm the price before anything is booked.

What a thermal roof survey looks like in Clapham Junction
Carlyle's House, about 1.4 miles north, is one of the historic houses in the wider area around Clapham Junction. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. There are several hotels within about a mile and a half of Clapham Junction, 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.
Shop and office owners around Southside Wandsworth may find that a commercial roof can be photographed from above without anyone walking on it. If your house is among the older ones in the streets near Clapham Welsh Presbyterian Church, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Clapham Junction is about 3 miles south-east of Kensington, in Greater London. Surveys in Clapham Junction work the same way as everywhere we cover: a careful inspection, photos and a written report. Clapham Junction is one of the towns and villages in Greater London we cover for thermal roof surveys.
Every address in SW11, SW18 and SW4 is within our area for thermal roof surveys, from the main roads to the quietest streets. Whether your property is on York Road, Este Road and Home Road or a nearby road, we can survey it. You’ll find Clapham Junction on the A3207, which makes it straightforward to reach. Nearby, we also carry out thermal roof surveys in Battersea (1 mile south-east), Sands End (1 mile north-west), Chelsea Harbour (1 mile north-west), Wandsworth (1 mile south-west) and Clapham (1 mile east). Further out, we also cover London (4 miles north-east), City of Westminster (4 miles north), Marylebone (4 miles north), Kensington (3 miles north-west), St Pancras (5 miles north-east) and Shoreditch (6 miles north-east).

Can I check my roof myself?
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where applicable.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Common questions in Clapham Junction
Is my home in Clapham Junction listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is drone flying allowed in Clapham Junction?
It depends on the exact address and the weather on the day. The flight restriction zone around London Heliport in Battersea covers Clapham Junction, or comes right up to its edge. Before any flight there, we ask the heliport for permission, and the flight only goes ahead if it is 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. Each address is checked against all of them before the drone goes up. Strong wind or a downpour also stops a small drone flying, though the rest of the survey goes ahead either way.
What can thermal imaging tell me about my roof?
A thermal camera shows differences in surface temperature. The patterns can suggest wet insulation, gaps in insulation or heat escaping. Findings are checked with moisture readings.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Can thermal imaging show missing insulation?
The camera can point to heat loss and gaps in insulation. We don’t give energy ratings or heat loss calculations, but the report shows where to look more closely.
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, and moisture readings are used to check it.
Can you do a thermal survey in any weather?
The weather makes a real difference. It works best after a sunny day, with a dry roof surface and little wind. Rain and strong wind can make the images less clear, so we talk through the forecast as you book.
Do you need a thermal roof survey in Clapham Junction?
Unexplained damp is one of the main reasons people ask for thermal imaging. Water can travel under a roof covering or along timbers before it shows inside. The camera helps narrow the search.
These are some of the problems a survey can pick up:
- Patches of heat loss across the roof
- Wet insulation beneath the membrane
- Leaks far from where the stain appears
- Stains that keep coming back
Controlled parking zones are common in London, so mention any permit rules for Clapham Junction.
Questions to ask before you book
- What experience they bring
- Whether any drone flown is registered with the CAA
- What the report includes, and whether it has photos
- Will they check the loft as well as the outside?
